Evaluation of LSB Watermarking Scheme for Grayscale Images

With the recent advent in technology the availabili ty, access, transmission and manipulation of digita l data (such as images, audio, video, software etc.) have become very easy. Digital Watermarking is a technology developed to ensure and facilitate the data authentication, security and copyright protect ion. This paper incorporates the LSB watermarking o f grayscale images. The algorithm is simple and effects of various attacks are studied in terms of quality and efforts.
