The invention discloses a scene and compliance fused dynamic hierarchical data
encryption method and
system, and the method comprises the steps: obtaining multi-
source data, and carrying out the preprocessing of the multi-
source data, and obtaining to-be-encrypted data; key words in the to-be-encrypted data are extracted, and weight coefficients are distributed to the key words according to semantic roles and / or industry risk coefficients; according to the
data type, determining a characteristic value corresponding to each keyword; determining a scene coefficient and a compliance coefficient; based on the
weight coefficient, the feature value, the scene coefficient and the compliance coefficient, determining a data sensitivity
score and a data sensitivity level corresponding to the to-be-encrypted data; and based on the data sensitivity level, encrypting the to-be-encrypted data by adopting the
encryption strategy of the corresponding level. According to the method provided by the embodiment of the invention, the security of the high-sensitivity data is ensured, the resource waste caused by excessive
encryption is avoided, the whole process is automatic, the labor cost and the overall cost of security protection are greatly reduced, and the comprehensive efficiency of
data processing and security protection is improved.
