Then, if the uploaded file is related to the APP customer service consultation, the file can be judged to be fake and modified and can not be used as a basis for settlement of the claim of the user.
And step 410, if the number of times of loading the watermark on the file is more than 1, reversely deducing whether the monitoring information of the file is consistent with the related information of the user or not according to a watermark encryption rule. If so, go to step 411, and if not, go to step 412.
Specifically, in the embodiment of the present invention, when the number of times of loading the watermark on the file is greater than 1, it is proved that the uploaded file has appeared in the APP before, so that the device identifier of the uploaded file, the timestamp triggering execution of the operation of uploading the file, the user location information, the CustID, and the channeldid code can be reversely deduced according to the watermark encryption rule, and compared with the device identifier when the user actually uploads the file, the timestamp triggering execution of the operation of uploading the file, the user location information, the CustID, and the channeldid code, and whether the two codes are consistent or not is checked, thereby determining the authenticity of the file uploaded by the user.
Therefore, the embodiment of the invention reversely verifies whether the information source provided by the user is the APP real information by using the watermark encryption rule, thereby effectively preventing fraud and other behaviors of the user.
Furthermore, after the anti-fraud result of the file uploaded by the user (namely the authenticity result of the file uploaded by the user) is obtained, the anti-fraud result is real user data and is uploaded to the cloud storage server through artificial intelligence, the anti-fraud result is questioned and is transmitted to the artificial customer service in a mode of transmitting the user CustID, and the artificial customer service performs user return visit to confirm the authenticity of the file uploaded by the user.
Therefore, the embodiment of the invention reversely deduces the related information of the uploaded file through the watermark encryption rule, and judges whether the operation is performed by the user at the moment according to the information, thereby judging the authenticity of the uploaded file of the user. Further, by analyzing the user behavior, a blacklist judgment rule can be added to screen high-quality users for seat personnel.
In the processing processes of the three embodiments, the embodiment of the invention monitors the user behavior, and adds the encrypted watermark in the operation object of the preset operation after the user triggers the preset operation, so that the user sensitive information is protected, the user sensitive information is prevented from being leaked and maliciously tampered, and meanwhile, in the subsequent practical application process, the user information in the watermark can be reversely calculated according to the preset encryption algorithm and compared with the user information reserved in advance, so that the user information is used as an important basis for verifying the authenticity of the user data. In addition, the embodiment of the invention can trace back the information leakage source according to the monitoring information and can search the information leakage behavior.
On the basis of the foregoing embodiment, the embodiment of the present invention further provides that after different behaviors (screen capture, file upload, and file download) of the user are monitored by the monitoring mechanism, different tags are further added to the different behaviors, respectively, so that different operation behaviors of the user on the operation object can be effectively recorded. For example, if a user performs a screen capture operation, a file download operation, and a file upload operation on the same file, the embodiment of the present invention adds a screen capture tag, a download tag, and an upload tag to the same file, and records all operation behaviors performed by the user on the file.
Specifically, as shown in fig. 5, another watermark encryption method provided by an embodiment of the present invention is shown, where the method may include:
The type of one preset operation corresponds to one type of tag, for example, a screen capture tag corresponds to a screen capture operation, a download tag corresponds to a file download operation, and an upload tag corresponds to an file upload operation.
The embodiment of the invention integrates the label added for the preset operation with the equipment identifier, the timestamp triggering the preset operation, the user position information and the user identifier to obtain a string of binary character strings, and sign signature verification encryption is carried out on the binary character strings to obtain the encrypted character strings.

At this time, the encrypted character string can not only protect the user sensitive information, but also contain the user behavior tag information. The user behavior tag information clearly records all the operation behaviors of the user on the operation object.
In the practical application process of the embodiment of the invention, the embodiment of the invention can also adopt a preset decryption method to decrypt and obtain the watermark on the file, so as to obtain each label in the watermark and the time axis record obtained by the time point corresponding to each label, thereby judging the authenticity of the file.
