A New Semi-Fragile Watermarking Algorithm for Image Tampering Detection and Information Hiding

N.I. Glumov and V.A. Mitekin (Russia)


Digital watermarking, steganography, tampering detection.


The existing fragile (which means non-robust image modifications to any host) watermarking schemes and its applications to data hiding and image authentication are reviewed and analyzed in this article. A new semi fragile (i.e. robust to a certain set of host image modification methods) watermarking algorithm for combined data hiding and host image tampering detection is proposed, which allows to overcome major limitations and drawbacks of an existing watermarking schemes.
