Review on Binary Image Steganography and Watermarking
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 11
Abstract
In this paper we have reviewed and analyzed different watermarking and steganography techniques. This is based on image processing in spatial and transform domain. We have reviewed different techniques like data hiding by employing pairs of contour edge patterns, edge pixels, visual distortion tables, visual quality preserving rules, substitution, fixed partitioning of images, run lengths in spatial and using Discrete Cosine Transform, Discrete Wavelet Transform in transform domain. We have also represented analysis of these techniques in the form of table considering different factors of watermarking and steganography like visual quality, embedding capacity, security, robustness and computational complexity. It is concluded that spatial domain techniques are best with some factors like visual quality, while transform domain are best for some factors like robustness against attacks or other image processing operations and security. The data hiding capacity and computational complexity are common factors for both the domains.
