متن کاملBlind Image Watermarking Using a Sample Projection Approach
this paper presents a robust image watermarking scheme based on a sample projection approach. While we consider the human visual system in our watermarking algorithm, we use the low frequency components of image blocks for data hiding to obtain high robustness against attacks. We use four samples of the approximation coefficients of the image blocks to construct a line segment in the 2-D space....

متن کاملDigital Image Watermarking Techniques: A Comparative Study
Digital watermarking plays an increasingly important role for proving authenticity and copyright protection. The Internet is an ideal medium for selling digital goods it also makes redistribution of pirated files very easy. Digital watermarking can be used to insert invisible data into an object helping to track down pirate copies and to prove rightful ownership in a dispute. In this paper we p...
متن کاملTwo Novel Chaos-Based Algorithms for Image and Video Watermarking
In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...
