Abstract :
The main aim of this paper is to introduce a novel approach to preserve digital images´ copyrights. Hence as ISB scheme was selected in relation to the approach in an attempt conquer the issues of robustness and imperceptibility in watermarked imagery. According to the literature review, embedding the aimed secret bits (Watermark) is a problematic issue inside a host image (normal 8-bit, grey-scale) in a sense to make it undetectable by the HVS (Human Visual System) in addition to the matter that it is predicted to receive any attacks. The suggested method here represents an improved scheme for the embedding of ISB which maintains the robustness and cultivates the rate of security by employing repeated bits in various bit planes over an irregular order and it develops the LSB technique specifically in circumstances where robustness and imperceptibility are main points of assessment.
