Verify Digital Work Timestamp

Check if a digital work has been timestamped and verify its ownership

Verify by File Upload

Upload the original file to check if it has been timestamped

Verify by SHA-256 Hash

Enter the SHA-256 hash directly if you have it

How Verification Works
  1. We compute the SHA-256 hash of your uploaded file (or use the provided hash)
  2. We search our database for a matching timestamp record
  3. If found, we display the timestamp details and owner information
  4. The verification is logged for statistical purposes
