ABSTRACT
Security is the main concern in any field. With thefrequent attacks, it is a big challenge for the users toprotect the digital images which are transmittingover internet. Singular Value Decomposition (SVD)[7] provides a solution up to a greater extent. Thispaper mainly concentrates on the invisiblewatermarking. By using the Wavelets, invisiblewatermark embed into the original watermark. Themain focus concentrated on the wirelesscommunications; hence it is important to considersome factors into consideration, they are size of animage and requirements of bandwidth. Keeping inview of all these parameters, compression andtransmission should be done. The proposedalgorithm uses the SVD method along withcompression. The proposed algorithm is robustagainst all common attacks which exist in imageprocessing field. Tests have been done and resultsare satisfactory in terms of imperceptibility andsecurity.
