METHOD OF CONTENT-DEPENDENT WATERMARKING IMAGES BASED ON SECURITY VISUAL SECRET SHARING SCHEME

Abstract

A method of content-dependent watermarking images without embedding digital watermark based on visual secret sharing scheme, which allows to encrypt the digital watermark as a noise like secret and public shadow images using binary content-dependent wavelet-pattern with visually significance features and code table and to reconstruct the digital watermark by means of performing a logical operation (AND, OR or XOR) on a secret and a public shadow images. The results of computer simulation are represented.
