摘要：Digital Watermark processing technology has developed very rapidly during the recent years and widely applied to protect the copyright of digital image. In today's scenario protection of digital data is utmost necessary in every part of life. More robust methods are being developed to protect the proprietary rights of the multimedia. In this paper, an invisible watermarking technique is proposed, to embed multiple binary watermarks into digital medical images based on the concept of Visual Cryptography (VC). The proposed scheme embeds the watermarks without modifying the original host image. Multiple watermarks can be embedded as shares in the same image. In addition, the size of the watermarks is not restricted to being smaller than that of the original host image. Experimental results prove that, the output of proposed watermarking technique gives good similarity ratio, peak signal to noise ration and correlation coefficient.
