Artwork timestamping: protect and prove your creations

Creating an artwork is one thing. Proving that you are its author is another. LiveGalerie offers certified timestamping to establish reliable, verifiable and durable proof of prior existence.

Why timestamping matters

In case of dispute, it is not the person who created first who wins, but the one who can prove it.

A simple image file or online publication does not always provide strong proof.

Timestamping proves that an artwork existed on a specific date thanks to a cryptographic hash, electronic signature and blockchain anchoring.

The LiveGalerie timestamping system

Integrity

Each deposit relies on a unique SHA256 cryptographic hash. Any modification produces a different hash.

Signature

Proof files are electronically signed via GnuPG by LiveGalerie, and in personal mode an artist signature completes the chain of trust.

Blockchain

OpenTimestamps anchors the proof in the Bitcoin blockchain and establishes prior existence at a given date.

Public certificate

Each timestamped work may have a public certificate showing the proof identifier, deposit date, blockchain status and manifest hash.
