Data processing method and system and readable storage medium

The invention provides a data processing method, a data processing system and a readable storage medium, and the data processing method comprises the steps: obtaining a first public key and a first private key through a first algorithm, and obtaining a second public key and a second private key through a second algorithm; calling data information of the target equipment, executing first data encryption and second data encryption, acquiring encrypted data, storing the encrypted data in a file storage system, and uploading the stored information to an alliance chain; in response to an access obtaining request, obtaining the storage information through the alliance chain so as to download the encrypted data from a file storage system based on the storage information; and executing first data decryption and second data decryption on the encrypted data to obtain data information of the target equipment. The data information of the target equipment can be safely and reliably stored, the development cost is greatly
