A robust image watermarking technique based on image interlacing

As a result to ensure and facilitate data authentication, security and copyright protection of digital media, digital watermarking techniques are widely used in these domains. The non-blind watermarking systems have a main problem that for extracting the watermark image from the watermarked image, the original image is required. This means an overhead over the system resources like memory in both sender and receiver and bandwidth in communications channel. In this paper a solution and more effective non-blind image watermarking for this problem is proposed. The proposed method depends on using image interlacing as a new way in the watermarking systems. The performance of this method is compared with the ordinary non-blind watermarking technique over a wide number of images. Simulation results show the effectiveness of the proposed method and robustness against attacks.
