artHash is a new collaboration by Tom Ritchford and MovingPictures.Gallery (Benton C Bainbridge and Eric Barry Drasin)
artHash is a free, open-source system for digital artists to publish unique fingerprints of their work.
A hash is a unique fingerprint of a document: a short string of numbers and letters computed from the data in a digital file. That file will always return the same string of characters whenever it is ‘hashed’; however the hash may not be decoded to reveal the contents of a file. Thus, hashes may be shared publicly to fingerprint a digital artwork without exposing it to unauthorized copying.
Dragging documents and directories onto the artHash application generates this unique string using the high-quality SHA-256 algorithm. Upon generation of the code, the hash is published by artHash and can be disseminated to prove the identity of digital artworks.
The published artHash allows creators to demonstrate the primacy of their claim to any intellectual property in the form of a digital media file.
