Improved Digital Watermarking Techniques and Data Embedding In Multimedia
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 2
Abstract
Digital watermarking is a technology being developed to ensure security and protection of multimedia data. The purpose of digital watermarking is not to restrict use of multimedia resources, but rather to facilitate data authentication and copyright protection. In this paper, we discuss the general requirements on data hiding and digital watermarking. It includes topics in spatial watermarking;spread spectrum watermarking, spectral watermarking, and a brief survey of currently available commercial and public domain software are provided. The Improved technique is robust to image/video compression, and one can recover the hidden data without requiring the availability of the host signal. The new scheme enables signature images to be as much as 25% of the host image data, and hence could be used both in digital watermarking as well as in image data embedding.
