Step S5：Server reads the shooting date of the photo, is obtained and the shooting date from key database
Associated key, and the photo according to the key pair is decrypted, and obtains camera site coordinate.
Step S6：Server reads the job number of the photo, is obtained from engineering data base according to the job number
Take engineered locations coordinate；The camera site coordinate and the engineered locations coordinate are compared, so as to obtain judgement conclusion.
It should be noted that the execution object of step S1, step S5 and step S6 are servers, step S2, step S3 and
The execution object of step S4 is terminal device.
The key that terminal device networked server obtains in step S2 is the date on the same day based on server, with terminal device
Date setting it is unrelated.To ensure that user can only obtain a unique and newest key, and can not be set by changing terminal
The standby date is to obtain expired key.
Camera site coordinate is written to photo property information with encrypted test mode in step S4, shooting date and input by user
Location job number is written to photo property information with plaintext version.In order to which server end obtains the shooting day of cleartext information
Phase, so as to obtain key from key database according to shooting date.
The embodiment of the present invention passes through associated unique close with the date with being obtained from server to picture-taking location coordinate
Key is encrypted, and shooting date and the camera site coordinate of photo uniquely determine.By server end be decrypted and with
Engineering data base carries out comparison and is judged, has prevented the possibility manually played tricks, has ensured the authenticity of photo.
It should be understood that the size of the serial number of each step is not meant to the priority of execution sequence, each process in above-described embodiment
Execution sequence should determine that the implementation process without coping with the embodiment of the present invention forms any limit with its function and internal logic
It is fixed.
Camera site coordinate described in the present embodiment is the coordinate information that global positioning system (GPS) obtains.
Preferably, judgement conclusion described in step S7 is：If the camera site coordinate and the engineered locations coordinate
For error of coordinate within 100 meters, it is true to judge the photo；Otherwise, judge the photo for falseness.Due to global location
Geographical location information measured by system is there are certain error, and engineering construction place also includes certain geographic range, because
Obtained geographical location information allows certain deviation in the comparison for this, the deviation can be configured according to actual conditions or
Change.
Terminal device described in the present embodiment is the intelligent mobile terminal with camera shooting camera function, including mobile phone, tablet etc..
Preferably, server obtains further comprising the steps of after judgement conclusion：Server is using the judgement conclusion as mark
Label are write on photo, and are preserved to photo library.Server end will determine that label is write on photo, make one mesh of authenticity of photo

Preferably, the server is Cloud Server.
The course of work is as follows：Server generates unique key daily, the key be stored in key database and with day
Phase is associated, and in networking, the key on the same day is obtained from server daily for the terminal device of user, is stored in local, and daily zero
During point, proxima luce (prox. luc) key is abandoned.
User's using terminal equipment is taken pictures, and shooting unit work shoots required photo, while fixed by the whole world
Position receiving unit receives GPS information, obtains the camera site coordinate of spot for photography, and obtain the shooting date of terminal device simultaneously
Information and user input job number (or engineering name, title of spot for photography by information input unit on photo
Retain in the server), encryption unit is encrypted using key pair camera site coordinate, then by the shooting position of ciphertext form
The job number for putting coordinate, the shooting date of plaintext version and plaintext version is written in the attribute information of photo together, finally
It is uploaded to server, it should be noted that not necessarily uploaded on the shooting same day, the upload date has no effect on sentencing for authenticity
It is fixed.
After server receives the photo of user's upload, photo attribute information is analyzed, obtains the shooting of photo
Date (plaintext), job number (plaintext) and camera site coordinate (ciphertext), then according to shooting date from key database
Key associated with shooting date is found, decryption unit is decrypted according to key pair camera site coordinate (ciphertext), from
And obtain the camera site coordinate (plaintext) of the photo.
Server obtains engineered locations coordinate also according to job number (plaintext) from engineering data base.
Engineering data base is preset in server, and the position for including all job number information and the engineering is sat
Information is marked, according to advance setting, camera site coordinate and engineered locations coordinate are compared, so as to be judged, obtained
Judgement conclusion.
If the error of coordinate of the camera site coordinate and the engineered locations coordinate within 100 meters, judges the photograph
Piece is true；Otherwise, judge the photo for falseness.
Finally, server writes the judgement conclusion as label on photo, and preserve to photo library, and such later stage answers
When looking into, the engineering construction photo authenticity of upload is very clear.
