摘要：With the tremendous expansion of the Internet and multimedia technologies in the recent past, digital media is being manipulated more frequently. Digital watermarking technologies are one of the best solutions for authentication and copyright protection of digital data. In this paper, we applied our lossless image authentication technique on different datasets, random images and also on different blocks of the same image. Our lossless watermarking technique achieved good comparative results than the existing watermarking techniques both in terms of authentication and also in terms of the perceptual quality.
