“…Tetsuya et al (2011) have proposed the blind watermarking algorithm which does not need to refer any original data in the watermark extraction pro cess. They also discuss the analogy between the pro posed watermarking scheme and CT CDMA com munication systems based on complete complemen tary codes [18].…”

Digital watermarking, means of hiding/inserting a message, which can be an image, audio, video or text within the digital media. This hidden/inserting message can be later being extracted or detected for a variety of purposes. In this paper, a novel multi resolution logo watermarking scheme using fractional M band wavelet transform (Fr M band WT) is proposed. The watermark is embedded in the multiresolution Fr M band WT coefficients of low frequency bands of the host image using singular value decomposition (SVD). A multi resolution nature of Fr M band WT is exploited in the process of edge detection. Experi mental results of the proposed logo watermarking scheme are compared with the previously available water marking algorithms, fractional Fourier transform (FrFT), fractional wavelet transform (FrWT). Further, the proposed watermark extraction scheme is also tested on different attacks. The results after being investigated the proposed watermarking scheme shows a significant improvement as compared to other existing methods.
