Security Enhancement for Watermarking Technique Using Content based Image Segmentation

Devising new methods for watermarking with high robustness capabilities is still a challenging research problem. Most of the already proposed schemes suffer from some drawbacks. These proposed algorithms are robust for some range of attacks, but not most of them. As an example, they can not sustain in front of rotation or cropping. This work is a continuation of our works reported in [1-2]. The paper combines both techniques in [1] and [2] to propose a novel watermarking method for data hiding in media signal operating in the frequency domain using content based image segmentation with security enhancing technique. Such watermarking methods present additional advantages over the published watermarking schemes in terms of detection and recovery from geometric attacks, and with better security characteristics.
