Image watermarking is a tool used for authentication, ownership, intellectual property protection and many other security aspects of e-data. Dual watermarking is effective and efficient to prevent attacks, because it uses a private key and a public disordered mixing algorithm for the recovery of images. This can be a good way of protection of copyright and authenticity of images. In this paper, dual watermark scheme for protecting images is proposed, which provides a better way of protection of images against copyright infringements than the regular watermark technique.
