Therefore, any image attribute information can be prevented from being tampered by checking each image attribute information.
As shown in fig. 5, the system comprises a device terminal 1 and a server 2, wherein the device terminal 1 is connected with the server 2;
the device terminal 1 is used for acquiring solid image data and acquiring a plurality of image attribute information of the solid image data, and performing secondary encryption on each acquired image attribute information to acquire a copy of image ciphertext information;
the server 2 receives the solid image data, each piece of image attribute information and the image ciphertext information, decrypts the image ciphertext information to obtain each piece of decrypted image attribute information, and verifies each piece of decrypted image attribute information and the corresponding received image attribute information to obtain a verification result.
In the above embodiment, the device terminal 1 performs secondary encryption on the obtained plurality of image attribute information to obtain one copy of image ciphertext information, so as to prevent the encrypted image attribute information from being tampered, and further improve the authenticity of verifying the image attribute information before encryption and the decrypted image attribute information.
In the above embodiment, the server 2 is used to compare whether the image attribute information before being encrypted and the image attribute information after being decrypted are consistent to determine whether the solid image data is falsified in the transmission process, thereby improving the authenticity and validity of the solid image data.
In the above embodiment, it is determined that the solid image data and/or each image attribute information is tampered during transmission as long as any one set of verification data verified by the verification module 23 is inconsistent.
Further, in the above-described embodiment, as shown in fig. 6, the device terminal 1 includes:
the acquisition module 11 is configured to acquire field image data and obtain a plurality of image attribute information of the field image data;

and the transmission module 14 is connected with the second encryption module 13 and is used for transmitting the solid image data, each image attribute information and the image ciphertext information to the server 2.
In the above embodiment, the device terminal 1 first acquires the solid image data through the acquisition module 11;
then, the first encryption module 12 directly obtains a plurality of image attribute information of the on-site image data, and respectively encrypts the obtained plurality of image attribute information for the first time to obtain encryption information corresponding to each image attribute information;
secondly, encrypting all the encrypted information for the second time through a second encryption module 13 to integrate all the obtained image attribute information to obtain image ciphertext information;
then, the transmission module 14 transmits the solid image data, each acquired image attribute information, and the image ciphertext information to the server 2.
In the above embodiment, the first encryption module 12 and the second encryption module 13 perform secondary encryption on the obtained multiple pieces of image attribute information, so as to respectively encrypt, merge and confuse each obtained piece of image attribute information, and generate a piece of image ciphertext information; therefore, the encrypted image attribute information is prevented from being tampered, and the authenticity of the server 2 for verifying the unencrypted image attribute information and the decrypted image attribute information is improved.

In the above embodiment, the first verification information includes image capturing authorization credential information, and the image capturing authorization credential information is used to determine whether the terminal device is authorized to capture the field image data.
For example, after the device terminal 1 is connected to the server 2 (i.e., after the device terminal 1 successfully logs in), the first request unit 111 of the acquisition module 11 sends image acquisition authorization credential information to the server 2, the server 2 receives and sends a first verification result according to the image acquisition authorization credential information, and the first receiving unit 112 receives the first verification result;
when the server 2 judges that the device terminal 1 is authorized according to the image acquisition authorization voucher information, the first verification result is verification passing, so that the first processing unit 113 performs acquisition operation;
when the server 2 determines that the device terminal 1 is not authorized according to the image capturing authorization credential information, the first verification result is a non-verification result, so that the first processing unit 113 does not perform the capturing operation.
Further, in the above-described embodiment, as shown in fig. 8, the transmission module 14 includes:
a second request unit 141 for sending a transmission request to the server 2 according to the HTTP communication technique;

In the above embodiment, the server 2 may be provided with a data service interface, and the second requesting unit 141 of the transmission module 14 of the device terminal 1 may send a transmission request to the data service interface by the HTTP communication technology;
the second receiving unit 142 receives the second verification result output by the server 2 according to the transmission request;
when the server 2 determines that the device terminal 1 is authorized according to the transmission request, the second verification result is that the verification is passed, so that the second processing unit 143 sends the solid image data, each image attribute information, and the image ciphertext information to the server 2;
when the server 2 determines that the device terminal 1 is not authorized according to the transmission request, the second verification result is non-verification, so that the second processing unit 143 does not perform the transmission operation.
