The invention discloses a hierarchical
encryption storage
system and management method for multi-dimensional anti-depression
drug component data in the field of medical
data security and
information management. The hierarchical
encryption storage
system comprises a
data acquisition layer, a sensitivity hierarchical module, a multi-dimensional
encryption engine, a distributed storage cluster, an
access control center, a
key management system and an audit
traceability module. The
data acquisition layer is used for acquiring and standardizing multi-dimensional component data of the anti-depression
drug; the sensitivity layering module calculates a data sensitivity index S based on an entropy method, and divides data into a public layer, an
internal layer and a core layer. The method solves the problems of coarse encryption
granularity, rigid authority management and weak anti-
attack ability in the storage of the existing anti-depression
drug component data (such as the molecular structure and
curative effect data of a 5-hydroxytryptamine
reuptake inhibitor), reduces the data
leakage rate by 92% or more, improves the access efficiency by 40%, and has good application prospects. The method is suitable for sensitive data full-life-cycle management of pharmaceutical enterprises and medical institutions.
