Abstract
This paper presents a proposed watermarking technique used for protecting images from tampering by the attackers and other third parties. This technique is consisting of three stages: pattern generation, watermark embedding and watermarking extracting. In proposed work, two patterns (primary and secondary) are generated from some features of the image that used as a watermark, then applying a genetic algorithm to get random, unique and robust patterns, the primary pattern will be embedded in the main diagonal of the cover image. In addition to generate and embed the secondary pattern in the secondary diagonal of the cover image, the purpose of secondary pattern is to ensure a secure connection between the sender and the receiver. When the sender sends the image, the recipient at first extract the secondary pattern, if this pattern is matched with original embedded one, this mean the image are kept from attackers and the receiver can extract the primary pattern, and, if the secondary pattern not matched, the recipient tells the sender to resend the image again. As a result the proposed technique gives good results when applied on different cover images, since the embedded watermark is imperceptible and unique enough to detect the tamper.
