Key dependent feature point based image Watermaking scheme

Abstract

An approach to a blind discrete Wavelet Transformation (DWT) domain feature point based image watermarking technique is proposed in this paper. The embedding of the watermark is performed into the image feature points defined by the Harris detector and the additional feature points are generated from the existing feature points using a key dependent algorithm. The proposed method is simple and secure. It is also experimentally found to be robust against various geometric and noise attacks. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2012.
