In this modern world Digital watermarking is of prime importance. This has increased the demand for copyright protection. Digital watermarking is a solution to the problem of copyright protection and authentication of multimedia data while working in a networked environment. In this paper a non-blind watermarking has been proposed that embed a randomly generated binary numbers as watermark. Human Visual System (HVS) has been used to embed the watermark below the detection threshold (JND). High quality of robustness and imperceptibility are achieved through Just Noticeable Difference (JND) base selection of the detail coefficients. The experimental results show that the proposed technique is more resistant against all types of common signal processing operations and geometric attacks.
