With the explosive growth of the Internet in recent years have become progressively advanced in the rapidly growing field of internet application, data securities, including copyright protection and data integrity detection, have become a vast concern. One key for achieving information security is digital watermarking, which embeds hidden information or secret data in the image [1]. This technology works as a suitable tool for identifying the source, creator, owner, distributor, or authorized consumer of a document or image. Watermarking can also be used to detect a document or image is illegally distributed or modified [2]. Watermark techniques can be divided into two groups: Visible and invisible, the visible watermark is used if embedded watermark is intended to be seen by human eyes, For example, a logo inserted into corner of an image. While the invisible watermark is embedded into a host image by sophisticated algorithms and is invisible to the human eyes [3]. In digital right management (DRM) systems, encryption and robust watermarking are two major schemes for applications [4], the encrypted digital if one bit is received erroneously during transmission, part or whole of received data would not be decrypted, leading to the uselessness of such contents. For robust watermarking, the watermarked contents and their original counterparts look similar, or even identical from subjective point of view. During the transmission, if some parts are received in error, the received contents can partly be recognized and the copyright can be preserved [1].
