Digital image watermarking based on VSS in BTC domain

Abstract

An image watermarking model based on visual secret sharing (VSS) is proposed for protection of ownership. In the embedding phase, the watermark is first divided by VSS into two parts: a hiding watermark and a secret watermark. Then only the hiding watermark is embedded into the original image and the secret watermark is reserved for watermark extracting by the owner. In the extracting phase, the hiding watermark is extracted from the watermarked image first and then directly superimposed on the secret watermark to recover the watermark information.

Genetic programming-based perceptual shaping of a digital watermark in the wavelet domain using Morton scanning

“…Pitas (1996) suggested a block-based method, where a bit stream is inserted in the luminance value in the blocks of the image. An image watermarking model based on visual secret sharing is proposed by Tai et al (2003). The technique was not robust against signal processing attacks, including image scaling and image rotation.…”
