A digital technique for art authentication

A digital technique for art authentication.

We describe a computational technique for authenticating works of art, specifically paintings and drawings, from high-resolution digital scans of the original works. This approach builds a statistical model of an artist from the scans of a set of authenticated works against which new works then are compared. The statistical model consists of first- and higher-order wavelet statistics. We show p...

A Group Digital Signature Technique for Authentication

A group digital signature technique using a digital signature algorithm and a challenge-response identification protocol is proposed to provide effective authentication. The proposed digital signature algorithm is based on solving quadratic congruence, factorization. and discrete logarithm problems. Based on the public key infrastructure, group members generate their public-private keys first. ...

Digital Art and Crowd Creation in Iran (Case Study: Tehran Annual Digital Art Exhibition)

In Being and Time Heidegger believes that Dasein is the only being who has existence, he also argues Dasein has two existential modes: authenticity and in-authenticity. inauthenticity is usual Dasein’s existence, A way of Being in which Dasein has strayed away of himself and has fallen into the chaos of others. In this way of Being he deals to beings as others do, just in terms of efficiency an...
