Abstract:
Abstract More information is transmitted in a digital format now than ever. Digital watermarking technology is a method of protecting copyrights for this information. In this paper, new watermarked algorithm is suggested. This algorithm consists of three stages, the first one, image is divided into several blocks, and these blocks are tested to find out the least dominant color channel in these blocks. This channel is used to embed data of watermark. The second stage is comparison process using key and each number in key represent specific bit location exist in one of two most dominant color channel. In case, the bit from the most dominant channel is equal to the bit that extracted from watermark, (zero) will be stored in Least Significant Bit LSB of least dominant color channel. Otherwise, (one) will be stored. The third stage is the key regeneration process. This research gives an excellent result by providing high quality watermarked image, as well as provide high degree of complexity through regeneration process and comparing key with one of two channels and rounding between them. Keywords:- Least Dominant Channel, New Watermark Algorithm, New Least Significant Bit, Copyright Protection.
