In this paper, the authors have proposed an efficient watermarking algorithm for copyright protection of digital images. This algorithm is able to embed or hide digital image such as company's logo or trademarks into original image. They have altered all of the R, G and B values of the image which is taken as signature data, to an array of data bits. Then the data bits are encrypted to unlike pixel positions on the host image depending on key value and image size. As a result, they get a watermarked image. After that they have formed three different image shares using any two components of R, G and B of entire watermarked image.
