Abstract

In this paper, it is shown that there is a fundamental flaw in the paper [Chih-Chin Lai, A digital watermarking scheme based on singular value decomposition and tiny genetic algorithm, Digital Signal Processing 21 (2011) 522-527]. The method has watermark ambiguity problem at detector and could not be used as a proof of ownership as stated in the paper. (C) 2013 Elsevier Inc. All rights reserved.
