A Review on Different Transform based Watermarking Techniques
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2016, Vol 7, Issue 4
Abstract
Over the past decades, watermarking plays a vital role in the branch of information hiding and it hides information in digital media. Watermarking is also used to prevent illegal usage as well as copyright protection or even source tracking. Along with the watermarking we can use the encryption for the extra protection of the images. To integrate both encryption and watermarking technology by the independence of and fusion of orthogonal decomposition, and for the comprehensive security protection of remote sensing images. In this paper we present a detailed survey of different existing watermarking algorithm and techniques for remote sensing image. We also discuss the issues and problems of each and every watermarking algorithm as a means for protecting copyrighted data. Hence this comparative study is not to examine the best algorithm, but to analyze the traditional techniques in order to help the researches to innovate more watermarking approaches in future.
