<Embodiment 1>
FIG. 1 is a functional block diagram showing a configuration example of an electronic device according to the first embodiment.
As shown in FIG. 1, the electronic device 1 according to the present embodiment has an acquisition unit 1a, a calculation unit 1b, and a storage unit 1c. Examples of the electronic device 1 include mobile terminal devices such as mobile phones (including those called smartphones), tablet terminals, and mobile PCs (Personal Computers), but the electronic devices 1 are stationary devices such as stationary PCs. You can also do it.

The calculation unit 1b can be included in, for example, a control unit that controls the entire electronic device 1. The acquisition unit 1a or a part thereof can also be included in this control unit. This control unit can be realized by, for example, a CPU (Central Processing Unit), a working memory, a non-volatile storage device that stores a program for controlling the entire electronic device 1, and the like. This storage device can also function as a storage unit 1c. Further, this control unit can also be realized by, for example, an integrated circuit.

The acquisition unit 1a acquires feature information indicating the characteristics of the usage of the nearby device (near device), which is a device located (existing) in the vicinity. Here, the device can be an electronic device of the same type as the electronic device 1, but for example, when the electronic device 1 is a portable type (portable type), a neighboring device is an installation type. , And vice versa.

Further, the above-mentioned feature information can refer to characteristic information (feature amount) regarding a usage method (how to be used) and a usage state of a nearby device, and specific examples thereof will be described later. Regarding whether or not it is located in the vicinity, for example, it can be made to correspond to whether or not the acquisition unit 1a can acquire the feature information of the device. That is, a device capable of acquiring feature information by the acquisition unit 1a can be treated as a nearby device. Since the acquisition unit 1a monitors such nearby devices and collects feature information, it can also be referred to as a collection unit, a monitoring unit, or the like.

The acquisition unit 1a may have, for example, a wireless communication unit that wirelessly communicates with a nearby device. This wireless communication unit can be configured to perform wireless communication based on, for example, a wireless LAN (Local Area Network) standard. In addition, this wireless communication unit may be configured to perform wireless communication based on other wireless communication standards such as Bluetooth (registered trademark; the same shall apply hereinafter) and ZigBee (registered trademark), including the IEEE802.15 standard. can. Examples of Bluetooth include Bluetooth Basic Rate / Enhanced Data Rate (BR / EDR) and Bluetooth Low Energy (LE). Therefore, the wireless communication unit can be configured to perform wireless communication using, for example, a short-range wireless communication technology such as RFID (Radio Frequency Identification). Further, this wireless communication unit may be configured to perform wireless communication based on a plurality of types of wireless communication standards.

However, the acquisition unit 1a may have, for example, a wired communication unit other than the wireless communication unit, or may have a photographing device such as a still image camera or a moving image camera. When the acquisition unit 1a is a wired communication unit, the feature information can be acquired by using a device in the same wired LAN as a nearby device. When the acquisition unit 1a has a photographing device, the acquisition unit 1a can be configured to have an extraction unit that extracts feature information of a nearby device from the data photographed by the photographing device. Further, the acquisition unit 1a may be a combination of a plurality of various examples as described above, and the calculation unit 1b, which will be described later, may appropriately configure an optimum configuration according to the feature information required for calculating the reliability. You can use it.

The calculation unit 1b calculates the reliability of the nearby device according to the feature information of the nearby device acquired by the acquisition unit 1a. The reliability can be defined as, for example, the higher the frequency with which the device is located in the vicinity, but the reliability is not limited to this.

The storage unit 1c can have a storage device such as a memory. The storage unit 1c stores the reliability calculated by the calculation unit 1b. Actually, the storage unit 1c stores information indicating the reliability (reliability information). The storage unit 1c can be configured to store the reliability for each nearby device. However, the calculation unit 1b or the like may be provided with a function of specifying a user so that the storage unit 1c stores the reliability for each user (for each user information).

As described above, in the electronic device 1 according to the present embodiment, feature information can be acquired from nearby devices, and the reliability thereof can be calculated and stored. As described above, according to the electronic device 1 according to the present embodiment, it is possible to easily collect information on a reliable device.

Then, based on the reliability stored in this way, the electronic device 1 can distinguish a reliable device (device) from the feature amount of the nearby device. Further, the electronic device 1 can identify a reliable user by storing the reliability for each user. In other words, according to the electronic device 1 according to the present embodiment, a reliable device or user (for example, a user account) is derived from the action record of the actual device (the action record of the user who moves with the device). be able to.

As a result, the electronic device 1 uses this reliability as information for automatically determining whether or not it is a reliable device (or user) when using a new service, and the device is based on the reliability. (Or user) can be registered. Therefore, for example, when registering for a service for communicating using the electronic device 1, it is possible to automate the registration of a device or user that one can trust and eliminate troublesome authentication processing. That is, the electronic device 1 can be configured to automatically register a reliable user or device using the reliability, and the security at the time of friend registration can be improved.

Further, in the present embodiment, it is possible to construct an information collection system including a plurality of such electronic devices 1. This information gathering system is a system in which a plurality of electronic devices 1 located in the vicinity of each other store the reliability of each other, and one electronic device treats the other electronic device in the vicinity as the electronic device 1 as a nearby device. The reliability of the nearby device is stored.

Further, the acquisition unit 1a can be configured to have a detection unit that detects a nearby device (detects that a nearby device exists in the vicinity). This detection unit can be realized by constantly operating the wireless communication unit, the wired communication unit, the photographing device, or a combination thereof as described above, and periodically executing the detection. That is, in the case of the acquisition unit 1a having the detection unit, when the device is located near the electronic device 1 and becomes a nearby device, the feature information of the nearby device is acquired, and the reliability of the nearby device is usually improved. Information can be collected from.

In this way, by providing a detection unit in the acquisition unit 1a to constantly monitor devices located in the vicinity, the electronic device 1 normally collects information on the state of nearby devices, and based on some feature information, the electronic device 1 normally collects information. A value (reliability) indicating whether or not it is reliable can be held.

<Embodiment 2>
The second embodiment will be described mainly on the differences from the first embodiment with reference to FIGS. 2 to 9, but various examples described in the first embodiment can be applied. FIG. 2 is a functional block diagram showing a configuration example of an information collection system including the electronic device according to the second embodiment.

As shown in FIG. 2, the information collecting system according to the present embodiment includes an electronic device 10 in which a setting unit 1d and a transmission unit 1e, which will be described later, are added to the electronic device 1, and an electronic device having the same configuration as the electronic device 10 ( Proximity equipment) 20 and can be provided. The acquisition unit 2a, the calculation unit 2b, the storage unit 2c, the setting unit 2d, and the transmission unit 2e in the neighboring device 20 are the acquisition unit 1a, the calculation unit 1b, the storage unit 1c, the setting unit 1d, and the transmission unit, respectively, in the electronic device 10. It can have the same function as 1e. The number of nearby devices 20 to be stored in the electronic device 10 is not limited to one, and may be a plurality of devices.

As feature information, the acquisition unit 1a includes position information of the nearby device 20, time zone information indicating the time zone in which the nearby device 20 is located in the vicinity of the electronic device 10, the strength of the radio wave emitted from the nearby device 20, and the nearby device 20. It can be configured to acquire at least one of the accelerations of.

The acquisition unit 1a is the position information (latitude and longitude information) acquired by the position information acquisition unit using the GPS (Global Positioning System) system or Wi-Fi (registered trademark) technology provided in the nearby device 20 as the position information. Can be obtained. In addition, the acquisition unit 1a can also calculate the position information from the image of the nearby device 20 captured by the photographing device.

Further, as feature information, the acquisition unit 1a provides position information in a situation where the nearby device 20 is not located in the vicinity of the electronic device 10, and a position in a situation where the nearby device 20 is located in the vicinity of the electronic device 10. It can be configured to acquire at least one of the information. At least in the former case, the acquisition unit 1a can acquire the position information (in this case, the past position information) from the nearby device 20 by communication. By taking into account the past position information, the calculation unit 1b can calculate the reliability based on the movement of the nearby device 20 not only when it is located in the vicinity of the electronic device 10.

The acquisition unit 1a can acquire the time zone information from the nearby device 20, but the acquisition unit 1a is not limited to this. For example, the acquisition unit 1a may obtain information (for example, device information) that it is located in the vicinity and add time to make it a part of the feature information. That is, the acquisition unit 1a can acquire, for example, the time when some information such as the position information can be acquired by the acquisition unit 1a from the value of the internal clock as the time zone information. The acceleration can be, for example, information acquired by an acceleration sensor provided in the nearby device 20.

Further, the calculation unit 1b can be configured to calculate the reliability for each device or each user. That is, the calculation unit 1b can be configured to calculate the reliability for each nearby device 20, and the storage unit 1c can be configured to store the reliability for each nearby device 20. In this case, the storage unit 1c stores the device information of the nearby device 20 in association with the reliability calculated for the device information. Alternatively, the acquisition unit 1a acquires the user information indicating the user of the nearby device 20 for acquiring the feature information, the calculation unit 1b calculates the reliability for each user indicated by the user information, and the storage unit 1c calculates the reliability for each user. Can be configured to store reliability. In this case, the storage unit 1c stores the user information of the nearby device 20 in association with the reliability calculated for the user.

Therefore, the acquisition unit 1a may be configured to acquire the device information or the user information at the same time when acquiring the feature information. The device information may be any one or more pieces of information such as the serial number, MAC (Media Access Control) address, and telephone number of the device, as long as the device can be identified.

The user information may be any information such as a name that can be identified by the user. When the proximity device 20 is a device into which an application program can be incorporated, it is preferable that the acquisition unit 1a acquires the application ID list as user information. Here, the application ID list refers to a list of IDs (user IDs) used in each application incorporated in the neighboring device 20. An application can be an application program to be executed in order to use a service. It is desirable that this application ID list includes IDs for applications for executing communication services.

The setting unit 1d sets at least one of the type of feature information acquired by the acquisition unit 1a and the type of reliability calculated by the calculation unit 1b (which information is considered to be preferentially trusted, etc.). The electronic device 10 does not have to be provided with the setting unit 1d, but if it is provided, the setting related to the collection of reliability can be changed, so that the reliability that more matches the intention of the user of the electronic device 10 is stored. Can be made to.

The transmission unit 1e collects information on its own device and spontaneously distributes it to a nearby electronic device (neighboring device 20 in this example), or transmits it at the request of the acquisition unit 2a. The information of the own device can be feature information or information that is the source thereof, such as MAC address, location information, application ID list, and the like. By providing such a transmission unit 1e, the electronic device 20 can also acquire feature information about the electronic device 10 and store the reliability of the electronic device 10.

The transmission unit 1e can be configured to have a wireless transmission unit, and in that case, when the acquisition unit 1a is provided with a wireless communication unit, the wireless communication unit can be used. Even if the electronic device 10 does not include the transmission unit 1e, the electronic device 20 can collect information on the electronic device 20 side because the electronic device 20 has a photographing device or the like as the acquisition unit 2a.

It was explained that it is desirable that the application ID list includes the ID of the application for the communication service. In this case, the electronic device 10 is executably incorporated with an application in which the user of the electronic device 10 communicates with another user who uses the other electronic device via a network such as the Internet.

In that case, it is desirable that the electronic device 10 determines the limitation of communication with the other electronic device in the application based on the reliability stored in the storage unit 1c. Here, the restriction of communication can refer to at least one of the possibility of communication and the degree of restriction. As a result, it is possible to perform automatic friend registration processing in the communication application, such as registering only highly reliable users as friends. In addition, the degree of restriction can include group restrictions and the like.

As described above, the limitation of communication with the other electronic device in the electronic device 10 can include the possibility of communication with the other electronic device. That is, the electronic device 10 can determine whether or not communication with the other electronic device in the application is possible based on the reliability stored in the storage unit 1c. In the electronic device 10, if the application has a function of registering a user of the other electronic device determined to be able to communicate as a communication target user, the above-mentioned automatic registration process can be performed. ..

Further, regarding the determination of the restriction, for example, the application can determine the restriction of communication with other electronic devices based on the reliability stored in the storage unit 1c, and the automatic registration process of friends according to this determination, etc. Can be executed. Alternatively, the electronic device 10 can be configured to provide its application with information indicating restrictions on communication with other electronic devices, which is determined based on the reliability stored in the storage unit 1c.

In addition, the restriction of communication with other electronic devices is limited to the restriction of communication with the user (user ID, etc.) of the corresponding other electronic device, that is, the restriction with the device may be imposed by such user restriction. can.

In this way, the electronic device 10 can automatically build a relationship of a certain service by using the reliability of the nearby device 20. Then, the electronic device 10 can determine the relationship with the user in the service for each user in the form of storing the reliability of each user. The electronic device 10 can determine the relationship with the device in its service for each device in the form of storing the reliability for each nearby device.

A specific example of the friend registration process as described above will be described with reference to FIGS. 3 to 9. FIG. 3 is a schematic diagram for explaining an example of information collection processing in the information collection system including the electronic device according to the second embodiment. FIG. 4 is a diagram showing an example of time zone information of another terminal collected by one terminal b in the information collection system of FIG.

The information gathering system shown in FIG. 3 shows a system used in a world in which six communities 101, 102, 103, 104, 105, and 106 of A to F exist. The community expressed here means an aggregate that shares position information with a small error for a certain period of time. The description in parentheses in FIG. 3, that is, homes 1 to 3, schools, workplaces, and circles is an example of a concrete representation of the community.

There is no specific information in the community itself, and it is a concept formed between terminals that share location information with a small error for a certain period of time. Here, the terminal as an example of the electronic devices 10 and 20 can be a smart device such as a smartphone or a wearable terminal. For example, the terminal a (111) of the community A (101) also belongs to the communities D (104) and F (106). This represents a case where the terminal a (111) belongs to each community at a different time zone. In addition, FIG. 3 illustrates the terminal b (112), the terminal c (113), the terminal d (114), and the terminal e (115).

Further, in the community A (101) of FIG. 3, for example, the smart device 121 not described with a, b, etc. does not share the position information with a small error with other terminals a, b for a certain period of time. Indicates a terminal. The smart devices 122, 123, and 124 are the same as the smart devices 121. In this way, even if you temporarily enter a certain community, it can be determined that it does not belong to that community, that is, it can be stored as having low reliability.

FIG. 4 shows the attribution information to the community in a certain week from the location information of each terminal. For example, information 202 of terminal c (113) and information 203 of terminal d (114) indicate that they belong to the same community from night to dawn (211) on weekday. Also, information 201 of terminal a (111), information 203 of terminal d (114), and information 204 of terminal e (115) indicate that they belong to the same community on Thursday evening (212). The hatching in FIG. 4 shows the hatching illustrated inside each of the communities 101 to 106 in FIG. 3, and represents the time zone belonging to each community. In this way, each smart device can express the state of attribution to a certain community at a certain time zone from the location information.

Here, a certain terminal (for example, terminal a) also stores its own position information, so that even when the terminal a moves, other terminals belonging to that community can be determined for each community of the destination. can do. In other words, the terminal can be configured to calculate the reliability of another terminal for each of its own position information (actually, for each position information having a certain range). More specifically, the terminal can be grouped according to its own position information, and the reliability can be calculated and stored for each group (that is, for each attribution state).

Next, an example of the software stack in the electronic device 10 exemplified by the smart device will be described with reference to FIG. FIG. 5 is a diagram showing an example of a software stack in each smart device in the information collection system of FIG.

As shown in FIG. 5, the smart device 301, which is an example of the electronic device 10, may have an application layer 302, a middleware layer 303, a driver layer 304, and a hardware layer 305. The collection module 306 as a range of software related to information collection related to the acquisition unit 1a, the calculation unit 1b, the storage unit 1c, the setting unit 1d, and the transmission unit 1e corresponds to the following part. That is, the collection module 306 has a setting screen 307 of the application layer 302, a controller 308 of the middleware layer 303, a database 309, an event handler 310, a producer 311 and a config (configuration information) 312.

The setting screen 307 can have a graphical user interface (GUI) related to the setting unit 1d. The controller 308 controls the entire collection module 306. The database 309 stores the collected feature information, device information (or user information), and reliability information calculated from the information. The event handler 310 controls the proximity sensor driver 314 described later to acquire the feature information of the nearby device and passes it to the controller 308. The controller 308 temporarily or semi-permanently stores this feature information in the database 309. The producer 311 calculates the reliability by referring to the feature information of the database 309 according to the config 312 in which the settings set from the setting screen 307 are described, and stores the reliability information indicating the reliability information in the database 309. The config 312 is information describing the settings set from the setting screen 307.

Further, the hardware layer 305 may have a proximity sensor 313 and the driver layer 304 may have a proximity sensor driver 314, which function as an example of the acquisition unit 1a. The proximity sensor 313 detects a device located in the vicinity based on, for example, Bluetooth.

The communication application can be executably held as a plurality of applications 315, 316 and the like in the application layer 302. Each of the applications 315 and 316 can access the database 309, and each of the applications 315 and 316 refers to the reliability information, performs a registration process of friends and the like, and stores the application in the database 309.

Next, an example of the operation of the smart device 301 of FIG. 5 will be described with reference to FIGS. 6 to 9. FIG. 6 is a flow chart for explaining an example of operation in the smart device 301. FIG. 7 is a diagram showing an example of the format of the database 309, FIG. 8 is a diagram showing an example of a reliability calculation formula applied to the smart device 301, and FIG. 9 is a reliability graph calculated by the smart device 301. It is a figure which shows an example.

The user (user) 401 of the smart device 301 specifies the activation of the search function of the nearby device (neighboring terminal) from the setting screen 307 (step S11). After the activation is specified, the collection module 306 saves the setting for enabling the search function of the neighboring terminal in the config 312 (step S12), and activates the producer 311 and the controller 308 (steps S13 and S16).

The controller 308 activates the event handler 310 for receiving the event from the proximity sensor driver 314 (step S14). The activated producer 311 confirms the setting of the search function of the neighboring terminal by referring to the config 312 (step S17), and if it is valid, periodically monitors the neighboring terminal.

First, the producer 311 collects the information (MAC address, location information, application ID list) distributed by the own terminal (step S18). After that, the producer 311 reads out the information (MAC address, location information, application ID list, reliability) of the terminal (denoted as "A" here) that was close to the current time from the database 309 (step S19), and they (Step S20).

The database 309 is held, for example, in the format shown in FIG. Here, in order to simplify the explanation, it is described in KVS (Key-Value Store). However, the database 309 may be described in another format such as RDBMS (Relational DataBase Management System).

In the format shown in FIG. 7, it has two lists, a reliable device list (reliable_devices) 5001 and a reliable device list (candidate_devices) 5002, respectively. The components in both lists 5001 and 5002 have the same components. This component has a terminal MAC address (mac) 5011, a registration time (registered_at) 5012, an updated time (updated_at) 5013, and an estimated time zone (approx_period) 5014. Further, this component has a latitude (lat) 5015, a longitude (lng) 5016, a previously calculated latitude difference (d_lat) 5017, a previously calculated longitude difference (d_lng) 5018, and a reliability 5019.

The estimated time zone (approx_period) 5014 is in map format and holds a start time (begin) 5101, an end time (end) 5102, and a continuity (continuity) 5103.

The continuity 5103 counts the number of consecutive appearances during the estimated time zone. By being continuously counted for a certain period of time, it becomes a determination material for the terminal to move (transition) from the reliable device list (candate_devices) 5002 to the reliable device list (reliable_devices) 5001.

Returning to the description of FIG. Since the estimated time zone in which a certain terminal A is considered to be close to each other is held as the estimated time zone (approx_period) 5014 on the database 309, processing is performed on the terminal group including the current time. The producer 311 transmits the collected information (information of the terminal A) to the terminal A (step S21). The producer 311 can receive the latest feature information (information including the location information and the application ID list) of the terminal A as the response (step S22).

Further, when the event handler 310 receives the feature information (information including the position information and the application ID list) of the terminal A as the response in step S21 (step S23), the event handler 310 delegates the operation to the controller 308 (step S24). The controller 308 confirms the state of the terminal A with reference to the database 309 (step S25), calculates the reliability from the time and position information, and updates the database 309 to that value (step S26).

For the calculation method of reliability, for example, the mathematical formula of FIG. 8 can be applied. In this formula, the reliability can take a value in the range of 0≤Reliability≤1.

For example, if the amount of change of the two elements (latitude, longitude) is within the permissible value, the reliability of each can be calculated as 1. As illustrated with respect to latitude in FIG. 9, if the value exceeds the permissible value and is below the threshold value, the reliability is lowered. If the threshold is exceeded, the reliability of each can be calculated as 0. The same applies to longitude. In the mathematical formula of FIG. 8, _ai is the slope of each element function and can be made different between latitude and longitude, and when other elements are also adopted, the slope of the element can also be made different. ..

In addition, the producer 311 can also transmit the information of the own terminal collected in step S18 to the neighboring terminal (step S27). When the event handler 310 receives the response from an unknown terminal (denoted as "B" here) (step S28), the event handler 310 delegates the operation to the controller 308 (step S29). The controller 308 confirms the state of the terminal B with reference to the database 309 (step S30), and if it does not exist in the enable_devices5001, registers it in the candidate_devies5002 (step S31). When the continuity 5103 of the approp_period 5014 of the terminal B exceeds a certain period (for example, 2 weeks (14 days)), the information of the terminal B is moved to the enable_devices5001.

That is, the controller 308 calculates the reliability of the terminal B from the time zone information such as the time and the position information, confirms it in the database 309, and updates the reliability as necessary. Of course, it is not necessary to compare the information acquired in step S30 with the information in the database 309 and calculate the reliability if it is unnecessary (if it is the same information).

As described above, the smart device 301 manages, for example, the estimated time zone (start / end time, number of continuations) of nearby devices, and based on the amount of change in position information (latitude / longitude), the reliability (reliability) ( Whether or not it is a reliable device, or whether or not it is a device that seems to be reliable, etc.) can be registered. Further, the smart device 301 can update the reliability based on the newly acquired feature information. Further, the smart device 301 can have a function of automatically registering as a friend when the nearby device 20 is a reliable device when the communication application is installed.

When installing a new community application, there are many troublesome points such as manually searching for information registration of friendships and registering while physically present. However, by applying this embodiment, it is possible to easily collect information on a reliable device, and by constantly holding a highly reliable terminal in the own terminal, after the application installation is completed. , You can complete friend registration automatically.

Further, when a plurality of applications different from each other are executably incorporated in the electronic device 10 such as the smart device 301 as illustrated in the applications 315 and 316, the following restrictions can be applied. That is, first, the calculation unit 1b calculates the reliability of the neighboring device according to the feature information acquired by the acquisition unit 1a for each predetermined time zone. Then, the electronic device 10 determines the restriction of communication with other electronic devices for each application based on the reliability of each time zone stored in the storage unit 1c. That is, the electronic device 10 can determine the type of community such as a family and determine the restriction of communication based on the reliability of each time zone.

For example, by estimating what the community is like from the time zone when the community is formed, it is possible to set it as a group generally realized in the communication application. For example, if a weekday community is formed from 20:00 to 8:00 every day, it can be estimated that the community is a "family". Also, if the acceleration of the terminal can be acquired, and if the amount of change in acceleration is almost 0 in the midnight time zone, it is a stronger "family" (the terminal is left asleep and sleeping). Can be estimated. Therefore, the terminals can be grouped according to the time zone information among the feature information of the neighboring terminals, the reliability can be calculated and stored for each group, and it can be determined whether or not the terminals can be trusted for each group. ..

More specifically, the application 315 can be an application for communication, and after installation on the smart device 301, refers to the library_devices5001 of the database 309 in the terminal. Since the terminal existing in reliable_devices5001 is considered to be a terminal that maintains a high degree of reliability with the community to which the own terminal belongs for a certain period of time, friend registration can be automatically performed. The application 316 is the same as the application 315, but the friend registration process can be performed based on the reliability of different groups (reliability calculated for different time zones).

As described above, it is preferable that the calculation unit 1b calculates the reliability of the neighboring terminal according to the feature information acquired by the acquisition unit 1a within a predetermined period. Whether or not it was acquired within a predetermined period (for example, a predetermined time zone) can be obtained from the time zone information as one of the feature information, but even if it is other types of feature information, the acquisition time can be confirmed and stored. You just have to go. By providing a period for measuring the reliability of neighboring terminals for a certain period of time in this way, terminals or users can be grouped.

Further, in this case, the electronic device 10 such as the smart device 301 can further include a period setting unit for setting the predetermined period. For example, this period setting unit can be provided in the setting unit 1d.

Applications 315 and 316 can also be configured to perform friend registration processing using different thresholds for a common reliability, in which case one of them will be registered as a friend more than the other. Become.

Further, as the degree of communication restriction, group restriction can be included as described above. Group restrictions can also be implemented by grouping based on a common reliability (reliability for each device or user) and setting restrictions for each group. Alternatively, as described above, the electronic device 10 is divided into groups based on its own position information, the reliability is calculated and stored for each group (that is, for each attribution state), and whether or not the electronic device 10 can be trusted for each group is determined. Can be decided. Further, both the time zone information and the location information can be used for grouping.
