And the backup record is carried out on the access record, so that the data access behavior is monitored and tracked, and the traceability and the credibility of the data are improved. The access authority and the control authority in the encryption processing method are set, so that the access and the control of the risk data of different levels are more flexible. Corresponding authority levels can be set according to different business requirements and security strategies, so that only authorized personnel can access and operate risk data of the corresponding levels, and compliance and security of data access are improved. By performing customized encryption processing on the risk data according to the risk level determination result, the security, privacy protection level and access control capability of the data can be improved. This helps to protect the financial data of the enterprise from risks and threats and ensures confidentiality and integrity of the data during transmission, storage and processing.
