PROJECT TITLE :

Block Based Robust Blind Image Watermarking Using Discrete Wavelet Transform - 2014

ABSTRACT:

Digital watermarking could be a process to provide authenticity by hiding a knowledge into a picture or audio or document. Hiding of data in an image can be tired frequency domain. Since frequency domain based mostly techniques are more sturdy against signal processing and geometric attacks than time domain primarily based techniques and watermark will also be extracted with(non blind) and while not(blind) original cowl image. In this paper we have a tendency to proposed a blind image watermarking technique which embeds watermark into image in frequency domain using discrete wavelet transform, singular worth decomposition and torus automorphism techniques. This technique extracts watermark without cowl image and additionally proved that this technique is robust against completely different signal and non signal processing attacks.
