Muttoo %A Sushil Kumar %J BVICAM's International Journal of Information Technology %D 2012 %I Bharati Vidyapeeth's Institute of Computer Applications and Management %X Image watermarking is considered a powerful tool forCopyright protection, Content authentication, Fingerprintingand for protecting intellectual property. We present in thispaper a watermarking algorithm based on block wise changingmagnitude of DFT domain. This algorithm can be used as anapplication for copyright protection. To provide multi-levelsecurities we have first used best self-synchronizing T-codes toencode the watermark. The encoded watermark is thenembedded into the cover image using a stego-key. We haveanalyzed our algorithm against noise such as Salt and Pepper,Gaussian and Speckle. %K Watermark %K DFT Composition %K Image Processing %U http://www.bvicam.ac.in/bijit/Downloads/pdf/Issue8/05.pdf
