AbstractRapid development in technology to provide security to data in the form of images is a major issue. So to provide security to the original image, watermark image embedded in it. In this paper we use self embedded watermark using fragile watermark technique. Authenticity of an image can be tested using block based technique of self embedding fragile watermarking; to represent the entire image the feature image watermark is used. In each 2x2non overlapping block four authentication bits and eight recovery bits are generated. In each block three least significant bits are embedded with authentication bits and recovery bits are embedded in the three least significant bits of the mapped block This paper mainly summarizes the Selection of image, method of watermark insertion, detection and tamper localization and recovery procedure. The experimental results of this proposed method shows visual quality of image recovery better than some of the schemes.
