Abstract

In this paper. we describe a novel content-based image signature for authentication using the ridgelet transform. The signature is extracted from the Radon dornain and entropy coded after a 1D wavelet transform, which is essentially the so-called "ridgelet transform". Unlike traditional authentication signatures. it has the ability to localise tampering at a high resolution, robust to content-preserving manipulations such as compression and allows a progressive authentication.
