Resumen

With the growth in digital world, it is becoming more important to find a method toprotect the security of digital media. An image watermarking model based on visual secretsharing (VSS) is proposed for protection of ownership. In the embedding phase, thewatermark 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 secretwatermark is reserved for watermark extracting by the owner. In the extracting phase, thehiding watermark is extracted from the watermarked image first and then directlysuperimposed on the secret watermark to recover the watermark information. Digitalwatermarking has been proposed as a possible brick of such protection systems. However,application of watermarking for multimedia content protection in realistic scenarios posesseveral security issues.A digital watermarking technique is used to generate meaningful shares. The secret imageshares are watermarked with different cover images and are transmitted. At the receiving side,the cover images are extracted from the shares and stacked one by one which reveals the secretimage progressively. Digital watermarking using visual cryptography provides improved securityfor encrypting secret images.
