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.
