Art Spotter

A free artwork passport for an artist's work. Makes a certificate for a work (title, artist, year, medium, size, edition) with a fingerprint of its picture, as printable text and schema.org data the artist can publish, so anyone can later check the picture is unchanged.

make_artwork_passport
