ARTtrust makes it possible to provide a unique identity to each print in an edition or to each unique work. 
It is a self-certification system. Artists protect their works and their authors' rights and guarantee to buyers the authenticity of purchased work.

Buyers verify the authenticity of the work thanks to the silver tag applied to the work and the gold tag applied to the certificate of authenticity.

Guarantee: 

The traceability of the work by buyers or collectors, everywhere in the world.

The longevity and the lifetime certification of the tags and of the system.

Buying "ARTtrusted" works of art guarantees the origin and the value of the investment, whether at time of purchase or at resale, and for a very long time.
