Robust perceptual image hashing via matrix invariants
In this paper we suggest viewing images (as well as attacks on them) as a sequence of linear operators and propose novel hashing algorithms employing transforms that are based on ...

Wavelet-based blind watermarking of 3D models
Watermarking of 3D meshes has received a limited attention due to the difficulties encountered in extending the algorithms developed for 1D (audio) and 2D (images and video) signa...

Improved watermark detection robust to camcorder capture based on quadrangle estimation
In this paper, we propose a blind watermark detection scheme which is robust against composite geometric distortions. The composite geometric distortions mean that an image or a v...

Hierarchical watermarking for secure image authentication with localization
Several fragile watermarking schemes presented in the literature are either vulnerable to vector quantization (VQ) counterfeiting attacks or sacrifice localization accuracy to impr...
