Description

Anti-peeping password input device and method thereof

The present invention relates to a password input device and a method thereof, and more particularly to a password input device and method thereof that do not have to be peeked at by others when inputting a password.

Information security is important in the promotion and popularization of information technology. Passwords are currently used as a method of security protection for information systems. The input of passwords is the first to be hidden, but it is true to enter passwords in public places. Can't feel comfortable, such as the password authentication or password setting of the bank teller computer or ATM ATM, which is the process that most people will experience. In the case of entering the password in so many people, the party must be wary and worried about the password. It is often necessary to cover up by others, but after all, such password input is still unsafe, and it is easy for others to see and harm their own rights and interests.

The disclosure of the patent No. 102139913 (hereinafter referred to as the first case) provides a method for preventing cryptographic information from being peeked by using a mobile terminal and a wearable electronic device, and an electronic device having a first display unit. An input keyboard interface is displayed, and a password is displayed on the first button area of the input interface for a blank button that does not display a symbol or a number, so as to prevent others from peeking into the password, but the mobile terminal in the architecture requires a password. The input system is illustrated by ATM. The mobile terminal is the computer of the ATM itself. To make the ATM in the ATM computer use the technology of preventing the password from being sneaked, the ATM withdrawal must be modified. Program to change the original ATM The method of the first case is as follows: taking the fourth picture of the case as an example, the mobile terminal 120 is connected to the wearable electronic device 140 via Wi-Fi or Bluetooth in step S1, and the mobile terminal 120 receives and decrypts the encrypted data in step S5. In order to obtain the information of the random mapping table map1, the mobile terminal 120 displays the input keyboard interface key1 in step S6, and the mobile terminal 120 maps symbols or numbers according to the random mapping table map1 to each corresponding first button area and steps in step S7. The S8 user views the key interface graphic key2 displayed on the wearable electronic device 140, and touches the input keyboard interface key1 that does not display a symbol or a number on the mobile terminal 120, and the mobile device 120 will be touched. The numbers or symbols corresponding to a button area are used as input data, and the steps are not required to change the program of the mobile terminal in order to use the technology of the previous case. The general password input operation does not exist alone. Usually, an application system triggers the password input operation. Therefore, it is necessary to change the password input method that does not prevent voyeurism into a use technique to prevent the password input from being peeked. The application system to which the password input is attached must be modified. For example, in the ATM withdrawal system, the password input operation will be initiated at the appropriate time. The password input is included in the ATM withdrawal system program, so the password of the ATM withdrawal system is modified. To enter the technology used in the previous case, you must modify the ATM withdrawal program. Therefore, the design of the previous system-system architecture has low cohesion, high coupling force, and no independence. The password input operation must be dependent on the object or application system that requires password input. China Mainland Patent Licensing Notice No. CN202075725U (hereinafter referred to as the previous case 2) proposes a password input system including a password input keyboard, a display device and a background processing device, and the password input keyboard is a plurality of numbers for inputting numbers with a fixed position. a button, and the identifier of the number corresponding to the digit button is not displayed on each digit button, and is separately set from the password input keyboard, and the display device is configured to display the identifier of the digit corresponding to each digit button of the password input keyboard, and the background processing device Connecting the password input keyboard and the display device by wire or wirelessly, randomly setting a number corresponding to each numeric button of the password input keyboard, and transmitting the set digital identification code sequence to the display device; receiving and using The user enters the digital button signal input by the password, and inputs the number corresponding to each digit button of the keyboard according to the randomly set password to obtain the user password, which has the same problem as the previous case, taking ATM as an example, Background processing There is no communication device, especially the communication interface of HID, so it must be integrated into the original ATM system, so that the ATM can read the entered password, that is, the ATM program must be modified to be integrated with the background processing device. . In another case, various computer programs, whether they are system programs or general applications, have a program for logging in to enter a password. The structure of the previous case or the previous case 2 must be combined with the program for entering the password. If the login program obtains the password entered, it is necessary to modify the login password program to use the previous case or the previous case 2 to obtain the password. The design of the system structure of the former case 2 is the same as that of the previous case. The cohesion is low, the coupling force is high, and there is no independence. The password input operation must be dependent on the object or application system that requires password input.

Therefore, the present invention provides a password input device for preventing sneak peek and a password input method thereof, which has high structural independence, and can be read by the device of the present invention by simply reading the input data on the application system side. The password can be entered without anti-peeping effect without modifying any old system.

A schematic diagram showing the execution flow of the aligner.

The basic component of the present invention comprises a keyboard key pattern unit 101, an input unit 102, an output unit 103 and at least one communication unit, wherein the keyboard key pattern unit 101, the input unit 102 and the output unit 103 can be combined into various modules. , each module is equipped with a communication unit for each mode The communication unit 104 can be configured in the main control module 10 or the password input device 1. When the main control module 10 is configured, it is responsible for communicating with the input module 11, the output module 12, and the input/output module 13; The keyboard key pattern unit 101 is configured to randomly generate the keyboard key pattern and the key string of the button input by the user is corresponding to the original password according to the used keyboard key pattern, and the keyboard key pattern unit 101 generates the keyboard key position. When the keyboard key pattern unit 101 and the output unit 103 are disposed in the same module, the keyboard key pattern unit 101 directly passes the generated keyboard key pattern to the output unit 103. If the keyboard key pattern unit 101 is When the output unit 103 is set in different modules, the keyboard key pattern unit 101 transmits the generated keyboard key pattern to the output unit 103 through the communication unit 104 (if the device is a type 2 and type 3 architecture, the receiving end is communicated by the communication unit 104 Unit 122, and if the device is a type 5 architecture, the receiving end is received by the communication unit 134 and then transferred to the output unit 103); the output unit 103 is provided for a more personalized output for more secret output The keyboard key pattern generated by the keyboard key pattern unit 101 is provided to the user for knowledge, such as smart glasses or smart watches of the wearable device, and the personal mobile device such as a mobile phone or a tablet computer can output information more secretly. For example, one of the output units may be implemented, but not limited thereto. The input unit 102 is a device with a button blank, and provides a password for inputting, and the keyboard key pattern displayed by the output unit 103 is input to correspond to each. After the input, the input unit 102 sends the input key string to the keyboard key pattern unit 101. If the keyboard key pattern unit 101 and the input unit 102 are not in the same module, the function is utilized. The input unit 102 is a communication unit of the same module (if the device is a type 1 architecture and a type 2 architecture, the communication unit 112 is used, and if the device is a type 5 architecture, the communication unit 134 is used, and the architectures of various types are described below) The keyboard key pattern is sent to the communication unit 104, and then transferred to the keyboard key pattern unit 101, and the used keyboard key pattern corresponds to the original password, and FIG. 9(a) is the input unit 102. A possible aspect is that the button is blank. When entering the password, refer to the key patterns in Figure 9(b) and Figure 9(c) to determine the characters represented by the buttons in Figure 9(a). Figure 9 (b) and Figure 9(c) show the two aspects of the keyboard key pattern. In order to generate it in a random manner, there are actually many different keyboard key patterns. 9(b) and FIG. 9(a), the character represented by the button in FIG. 9(a) is determined by the corresponding position in FIG. 9(b), if used. In the keyboard key pattern of Figure 9(b), the button in the upper right corner of Figure 9(a) represents "0", and the button in the lower left corner is "*", but if the keyboard key of Figure 9(c) is used, For the bit pattern, the button at the top right corner of Figure 9(a) represents "3" and the button at the bottom left corner is "7". Since the keyboard is an unfixed key, the characters represented by the same key may be different in different input. When the user inputs the password on the keyboard, the entered password is only represented by the key of the button, and the key can be pressed. The number indicates that if a group of passwords contains 4 characters, it needs 4 key numbers. We call it a key string. The number in the circle in Figure 9(d) represents the number of the button, or the key. Bit or key number, key number can be numbered in any convenient way (such as button number or scan code), not limited to the format of this example. If a group of passwords are right upper, lower left, upper left, and lower right, the key string is 3, 10, 1, and 12. If the keyboard key pattern of Figure 9(b) is used, the corresponding password is 『0*6#』, and if the keyboard key pattern of Fig. 9(c) is used instead, the corresponding password is “3795”, and the number of keys and arrangement in Fig. 9 can be changed according to the actual use condition. The key string can contain the keys of any number of buttons.
