Submitted by B.Suresh M.Tech(D.S.C.E) 07004D0610 Under the esteemed guidance of Dr.P.Ramana Reddy M.E,Ph.D Associate Professor&Head Department of ECE JNTUACE,Anantapur Tamper-proof Watermarks with Embedded Reversible Data Outline  Objective  Introduction  Ownership is true?  Need for Reversible Watermarking  Reversible data embedding for tamper-proof Watermarks Feature map Extraction Location map Coefficient adjustment Watermark Embedding and Verification  Experimental Settings  Experimental Results  Conclusion Objective “Authentication of Tampered watermarks with Embedded Reversible Data” A reversible watermark is embedded in to robust watermark in the discrete wavelet transform (DWT) domain. Generally, the robust watermark is used to verify the owner ship, but if the robust watermark is tampered or faked by the malicious attacker, then it cannot prove the ownership when it is extracted from the original image. In this, we focus on authentication and reversibility of the robust watermark, because the purpose of reversible data embedding is to authenticate the robust water mark , not only for the authentication but also restoration.
