Place and time authentication of cultural assets

Abstract

This paper proposes a place and time authentication system for cultural assets. We develop a protocol that combines traditional cryptographic techniques with place and time information to generate a secure tag for each cultural asset. We model the attacker capabilities and show that our secure tag helps ensure the authenticity of works of art. Our system has been deployed and validated in Italian and Greek museums in the context of CUSPIS project. © 2008 International Federation for Information Processing.
