Data processing method and system based on SaaS and Pass platforms

The invention provides a data processing method and system based on SaaS and Pass platforms. The method comprises the following steps: receiving a target request sent by a client; decrypting the target request by using a private key corresponding to the client to obtain a user identifier and an operation instruction; determining a target address in a database based on the user identifier; and sending the operation instruction to the target address. In the embodiment of the invention, the target request sent by the client is the request encrypted by the public key, after the target request is received, the private key corresponding to the client is used for decrypting the request to obtain the user identifier and the operation instruction, and through the decryption process, the target request is prevented from being tampered in the transmission process. And the target address in the database is determined based on the user identifier, that is, the storage space corresponding to the client in the database is d
