Abstract
The development of multimedia technology has paved a way for rapid and fast communication. Various multimedia objects are transmitted through Internet once they have been captured. This has lifted up the concern over secure communication and also copyright protection issue. It is likely a case for the creator to be in dilemma whether the data had reached the intended person with all its imbibes integrity or not. Watermarking is an art of hiding owner’s signature in terms of text, audio, video, or image to prove the authenticity of an owner. This serves as safeguard for the originator in case of any misshape. In this paper, an efficient and blind watermark embedding method has been developed using Haar wavelet. The binary logo is used as a watermark that carries a sequence of zeros and ones. The single bit of watermark is embedded in k block size of the original image. The proposed scheme shows an excellent performance and has admirable robustness against various attacks.
