Sensitive data desensitization processing method and device

The invention provides a sensitive data desensitization processing method and device, relates to the technical field of data security, and can be used in the financial field or other technical fields. The method comprises the following steps: acquiring a sensitive data identifier for distinguishing sensitive data, and separating the sensitive data according to the sensitive data identifier; encrypting the sensitive data, and sending the encrypted sensitive data to a server; and if the encrypted sensitive data returned by the server is received, decrypting the encrypted sensitive data, and carrying out desensitization processing on the decrypted sensitive data. The device executes the method. According to the sensitive data desensitization processing method and device provided by the embodiment of the invention, the security of the desensitization data in the data transmission process can be further improved, the data security is ensured, and the labor cost and the time cost are saved by performing desensitiza
