The invention relates to the technical field of
file management, in particular to a file cabinet internet-of-things
access control and data tracing method. The method comprises the following steps: firstly, generating a multi-site
coupling digital key by extracting identity, authority and terminal characteristics of a borrower; during access
verification, a dynamic instruction is used as a logic
mask to extract effective site features, and a cabinet door is opened when the effective site features are consistent; then, synthesizing a preorder
fingerprint with the identity residue of the borrower, writing the preorder
fingerprint back to the physical tag, and generating a progressive
fingerprint chain by adopting a
cascade hash
algorithm in a circulation process; and finally, disassembling the fingerprint chain through a
reverse analysis model, and restoring the identity of the borrower in each link in combination with a
cosine similarity matching
algorithm. According to the method, the problems that offline circulation of the archives is non-traceable, authority
verification is easy to crack and data highly depends on a
central database are solved, and decentralized auditing and responsibility
traceability of the archives in the whole life cycle are achieved.
