Framis™Evidence verification

Verify a Framis evidence fingerprint.

Paste the SHA-256 hash of an image (64 hex characters) to confirm whether Framis has captured it as part of an infringement-recovery investigation, when, and whether the timestamp has been anchored on the Bitcoin blockchain.

Compute a SHA-256 of any file with shasum -a 256 file.jpgon macOS/Linux or PowerShell's Get-FileHash -Algorithm SHA256 on Windows.

What this is

Framis preserves chain-of-custody evidence for image-licence recovery cases. When we identify a candidate infringement, the exact bytes of the image are downloaded, fingerprinted with SHA-256, and that fingerprint is submitted to the OpenTimestamps Bitcoin calendar service.

Once Bitcoin confirms the batch (typically within a few hours), the fingerprint is locked into the most extensively-audited public ledger in the world. Anyone — including a court, opposing counsel, or the brokerage named in the case — can verify the timestamp independently of Framis.
