Specifically, in this embodiment, the core number threshold is 4; if the determination result in step S1 or S2 is no, it cannot be determined whether the computing capability of the client computer meets the requirement; if the determination result in step S2 is yes, it may be determined that the GPU of the client computer satisfies the computation capability, and the desensitization operation of the file may be performed directly on the client without further determining the performance of the CPU of the client computer.

Specifically, in this embodiment, the memory threshold is 8GB, and if the memory of the client computer is greater than or equal to 8GB, it can be determined that the memory meets the requirement.
S5: if the judgment result in the step S2 or the step S4 is yes, the client performs scanning and matching on the content of the file when transmitting the file, and if the content of the file is matched with the sensitive data information, performs desensitization operation on the sensitive data information according to a preset first desensitization method. Specifically, in this embodiment, the first desensitization method is data replacement, that is, the related real sensitive data is replaced with a fictive value, and the desensitization method can be set according to specific requirements to meet different requirements; if the judgment result in step S2 or step S4 is yes, it may be indicated that the computing power of the client computer meets the requirement of the computing power required by the desensitization operation of the sensitive data information in the file, and the client computer may perform the desensitization operation.
S6: and after desensitization operation is completed, marking the file after desensitization of the sensitive data information as a client desensitization file, and transmitting the client desensitization file to the server. After marking, when receiving the desensitization completed file, the server side directly stores the desensitization completed file without performing desensitization operation.

In step S7, the client needs to mark before sending the file, so that the server performs desensitization operation on the sensitive data on the file after receiving the file, specifically, in this embodiment, the second desensitization method is data replacement. If the judgment result in the step S3 or the step S4 is negative, it indicates that the computing capability of the client computer does not meet the requirement of the computing capability required by the desensitization operation of the sensitive data information in the file, and the client computer cannot perform the desensitization operation, so that the desensitization operation of the sensitive data information in the file needs to be performed at the server.
