摘要:In recent years, internet revolution resulted in an explosive growth in multimedia applications. Hence, concern about assurance of ownership rights has been mounting. In this paper, three public image watermarking techniques are proposed. The first one, called Single Watermark Embedding (SWE), uses the concept of Visual Cryptography (VC) to embed a watermark into a digital image. The second one, called Multiple Watermarks Embedding (MWE) extends SWE to embed multiple watermarks simultaneously in the same host image. Finally, Iterative Watermark Embedding (IWE) embeds the same binary watermark iteratively in different positions of the host image, to improve the robustness. Experimental results show that the proposed techniques satisfies all the properties of digital watermarking such as invisibility, security, capacity, low computational complexity and is robust to wide range of attacks.
