This platform assigns a unique Provenance Code to every published article and fixes a Content Fingerprint at the signing stage (computed with the SM3 national cipher over the title, author, source, abstract and body).

If an article is modified after publication, the recalculated fingerprint will differ from the archived one and this page will report "verification failed". This helps preventing tampering and also identifies unauthorized reprints: legitimate reprints must keep the tracing code and source attribution intact.

Note: the fingerprint does not cover volatile fields such as view counts or update times, so normal browsing counts and column changes do not affect verification.
