Abstract
This paper proposes a novel method for watermarking gray scale images in spatial domain by modifying the least significant bits of the pixels in the image. The embedding process creates a watermarked image with hidden information that in future can proclaim its ownership details. Data to be embedded is integrated in the image selectively on a subset of pixels using a rule that replaces the LSB’s of the image with the watermark signal bits. The method is successful in generating marked copies of the original image with high PSNR value and good visual qualities suitable for distribution via any media or publishing in Internet.
