Analysis on watermarking an image using hash partitioning with combination of GA-HBO with GA-BFA in BMP and JPEG images

New watermarking techniques have been created for multimedia security and copyright protection due to vast exchange of digital contents over internet. And, moreover this has become one of the major reason for the development of digital watermarking and to come up with innovations to protect intellectual properties of the digital world. Digital watermarking is the process that embeds data called a watermark into a multimedia object such that watermark can be detected or extracted later to make an assertion about the object. It may be visible or invisible. In this paper we are doing comparative study of watermarking two different formats of images i.e. BMP and JPEG image using a hybrid model which is a combination of GA-HBO based optimization techniques with another existing hybrid model which is a combination of GA-BFA based optimization technique with hash partitioning. Different types of parameters are going to be used for comparing the two different techniques. The proposed technique is implemented over the MATLAB.
