Description

Anti-counterfeiting method and device for engineering digital photos

technical field

The invention relates to an engineering digital photo anti-counterfeiting method and device for engineering digital photo management.

Background technique

In order to strengthen the on-site control of concealed projects and key links and provide real-time information that can be traced based on the actual situation of the construction of more dangerous projects such as power grid substations and lines, the power sector uses digital photo data to strengthen the safety and quality control process of power transmission and transformation projects. However, in the existing engineering digital photo management, the digital photos are taken on-site, and then sent to the server after sorting out and saved to the server. During this process, it is easy to make up photos, synthesize photos, etc., which affects the authenticity of digital photos. In the prior art, there is no method that does not affect the existing digital photo management steps and can effectively prevent the occurrence of false phenomena such as re-shooting and synthesis.

Contents of the invention

The technical problem to be solved by the present invention is to provide an engineering digital photo anti-counterfeiting method and device for the above-mentioned defects of the prior art.

In order to achieve the stated purpose, the present invention provides an anti-counterfeiting method for engineering digital photos, comprising:

A. The server pre-establishes the project photo database, basic photo library, abnormal photo library, false photo library, and the GPS information and date information of each project in the project photo database;

B. The user terminal takes digital photos containing GPS information and date information on the spot, adds an identification code to the digital photos, saves the digital photos locally and sends them to the server synchronously;

C. The server obtains the digital photo sent in step B, extracts the GPS information and date information in the digital photo, and compares it with the GPS information and date information of each project stored in the project photo database to determine whether the digital photo belongs to one of the projects , if yes, save the digital photo in the basic photo library of the server, if not, save the digital photo in the abnormal photo library.

D. The digital photos stored on the user end are sorted by the staff and uploaded to the server. The server receives the sorted digital photos and checks whether there is a digital photo with the same identification code in the basic photo library. If it exists, the basic The digital photo in the photo library is replaced by the corresponding received digital photo. If it does not exist, it is judged that the received digital photo is a fake photo and stored in the false photo library.

Further, the digital photos in the basic photo library are encrypted. Encryption is performed to artificially alter the digital photos in the underlying photo library anyway.

Further, in step C, after judging that the digital photo belongs to one of the projects, the digital photo is associated with the corresponding project.

Further, the date information is accurate to the second.

An engineering digital photo anti-counterfeiting device is characterized in that it includes a server module and a client module, and the client module includes:

A shooting module is used to take digital photos with GPS information and date information;

The photo additional identification code module is used to instantly add identification codes to the photos taken by the shooting module;

Detailed ways

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with specific examples:

GPS means the abbreviation of English Global Positioning System (Global Positioning System).

As shown in Figure 1, a kind of anti-counterfeit method of engineering digital photo, comprises

Step 101, the server pre-establishes a project photo database, a basic photo database, an abnormal photo database, and a false photo database, and the GPS information and date information of each project are established in the engineering photo database.

Step 201, take a digital photo that includes GPS information and date information on the spot, step 202, add an identification code to the digital photo, step 203, save the digital digital photo with the added identification code locally, and step 204, synchronize the digital photo with the added identification code The photo is sent to the server;

The identification code is a number used to distinguish different photos, and may be a random binary code or other similar codes. In order to facilitate the realization, the identification code can not be added, and the GPS information in the photo and the date information accurate to the second can be used instead of the identification code, thus greatly simplifying the steps and improving the efficiency.

Step 301, extract the GPS information and date information in the digital photo and compare it with the GPS information and date information of each project in the project photo database, and judge whether the digital photo belongs to one of the projects, if so, go to step 302, the The digital photo is associated with the project and stored in the basic photo library of the server, if not, go to step 303 to save the digital photo in the abnormal photo library.

The engineering GPS information in the engineering photo database includes the longitude range value and the latitude range value, the time information includes the time range value, the GPS information in the digital photo includes the longitude value and the latitude value, the time information is the time value, and the time value in the digital photo Compare with the time range value in the project photo database and judge whether the time value is within the time range value range. If not, the photo does not belong to the project. Compare the longitude range value and the latitude range value to determine whether it is within the range. If not, it is judged that the GPS photo does not belong to the project. If it is, then the digital photo belongs to the project. Through the comparison of GPS information, ensure that the photos are taken on site, and through the comparison of time, ensure that the photos are taken during the construction stage, and then save the digital photos in the basic photo library as real photos. When the scope of the project location is irregular, the exhaustive method can be used to realize .

After the staff organizes the digital photos stored locally, it proceeds to step 401, where the sorted digital photos are sent to the server, and in step 402, the server receives the sorted digital photos and checks whether there is an identical identification code in the basic photo library. If it exists, then enter step 403, replace the digital photo corresponding to the received digital photo with the digital photo in the basic photo library, if it does not exist, then enter step 404, judge that the received digital photo after sorting is a fake photo, and Save to fake photo gallery. When replacing a digital photo, the file path and file name of the original digital photo are not changed, only the content of the digital photo is replaced. Since the digital photo in the basic photo library is a real photo, the original layout of the digital photo is maintained, and the The authenticity of the photos prevents the content of the photos from being modified when the photos are sorted out afterwards.

Take the photos of the foundation trunking taken by the construction project department on the spot within the specified time as an example. After taking the photos, add an identification code to the photo of the foundation trunking, such as: 101010100101010101, and then send the photos of the foundation trunking to the server and save them locally , for the sake of illustration, the photo of the foundation line trench on the server side is represented by photo A, and the photo of the local foundation line trench is represented by photo B. Photo A judges that photo A belongs to the project through GPS information and time information and saves it in the basic photo library; photo B , after sorting out, the path and name of photo B were changed to ××Construction Project Department Quality Management Digital Photo\Civil Works\***Unit Project\Foundation Inspection Trough 001, after sending to the server, find the basic photo library through the identification code In the corresponding photo A, replace photo B with photo A, while keeping the name of "foundation inspection tank 001" and the corresponding file directory unchanged.
