Ambiguity attacks on robust blind image watermarking scheme based on redundant discrete wavelet transform and singular value decomposition

Blog Article

Among emergent applications of digital watermarking are copyright protection and proof of ownership.Recently, Makbol RECT DRM Table Set (5/CN) and Khoo (2013) have proposed for these applications a new robust blind image watermarking scheme based on the redundant discrete wavelet transform (RDWT) and the singular value decomposition (SVD).In this paper, we present two ambiguity attacks on this algorithm Main Data Cable that have shown that this algorithm fails when used to provide robustness applications like owner identification, proof of ownership, and transaction tracking.Keywords: Ambiguity attack, Image watermarking, Singular value decomposition, Redundant discrete wavelet transform.
