Record integrity

Check the record.

Compare a research record’s SHA-256 fingerprint with its archived version. This checks record integrity. Scientific findings require examination of the study’s methods, evidence and review status.

Verify a publication

Use the local record number shown on a publication page.

Paste the 64-character checksum from the record you want to compare.

Checksum matches

The fingerprints match.

The SHA-256 matches the archived canonical record. This confirms record integrity only, not scientific validity, independent review or general system safety. Publication notice status: corrected. Read the record notices.
