Abstract
AbstractData hiding process hides secret data in a media and reversible image data hiding is a technique in which the cover image can be completely restored after the extraction of secret data. In this paper a simple method is proposed for reversible data hiding in image blocks, by calculation of correlation matrix before data embedding. New data hiding method in these blocks is applied, by considering the pattern of correlation matrix and correlation threshold. Experimental results show that this method is capable of providing a great embedding capacity without making noticeable distortion with high PSNR.KeywordsReversible data hidingcorrelation matrixthresholdingblockssum-blockerror correlation
