This invention provides a method and
system for verifying and tracing file fingerprints for
scientific instrument data, comprising: Step S1, acquiring user identity information and instrument identifier of the
scientific instrument, identifying the
original data file through file monitoring and automatically collecting basic
metadata to generate labeled
metadata; Step S2, calculating the file
fingerprint based on the
algorithm identifier using a digest
algorithm and writing it into a
fingerprint database; Step S3, performing
fingerprint comparison on the file fingerprints; if the fingerprints are the same, reusing the existing
content object identifier and adding a new version
record; if they are different, creating a new
content object identifier and adding a new version
record; and when the same reservation identifier, upload
time difference not exceeding a preset threshold, and fingerprint inconsistency are met, creating a version fork and recording the fork
reason code and fork reason
payload for
traceability; Step S4, performing
verification processing on the downloaded file. The beneficial effect is that this invention can meet the comprehensive requirements of
traceability, auditability, and real-time performance for the
security management of
scientific instrument data.
