This paper presents a watermarking method using signatures for still images. An image authentication approach is requested to guarantee reliability of conveyed image data. To protect copyright, watermarking with digital signature is required. The watermarking method is a tool for ownership identification or content honesty information. The conventional watermarking methods are not directly applicable. To alleviate this issue, we propose a new watermarking method which uses signature and Sobel mask. We apply Sobel mask to classify image into two regions: edge and smooth regions. Pre-generated diagonal and anti-diagonal shape patterns are applied to generate specific signature for watermarking. Performance assessment is conducted in simulation results section. Watermarking signatures are embedded in the test images, and three metrics were applied to assess the performance.
