TITLE of the Paper Presented
Optimization of Stego Image retaining secret information using Genetic Algorithm with 8-connected PSNR
ABSTRACT of the Paper Presented
Due to the fast advancement of internet and digital technology, secured transmission of data over networks offers a great challenge. This problem of secrecy of information has long been received the attention of researchers due to its immense demand in real life applications such as information security systems. The problem is to optimize the stego image close to the cover image without affecting the secret embedded image, resulting in high visual stego image quality. In this paper, we have presented an improved genetic algorithm as the optimization algorithm to solve this problem. We have proposed a heuristic initialization technique to generate initial population and a new fitness function based on the Peak Signal to Noise Ratio (PSNR) obtained from 8-connected neighbors of each pixel. The proposed genetic algorithm is applied for the entire stego image and executed for a certain number of generations. The experimental results demonstrate that the proposed scheme is found to be relatively better than some existing steganography techniques in terms of enhanced PSNR of the stego image.
It is the first time I went abroad, alone, that again to present my paper in an International Conference. It also got published in the Science Direct journal by Procedia Publications – Elsevier.
I went to Singapore to attend the 19th International Conference on Knowledge-Based and Intelligent Information & Engineering Systems (KES 2015) to present my paper titled “Optimization of Stego Image retaining secret information using Genetic Algorithm with 8-connected PSNR”. Most of the other presentations were presented by professors or PhD students of very renowned universities all over the world. I was feeling blessed to be a part of such an event. I listened to many other presentations and the sessions were very enriching. I met and talked to some of these very talented people. They expressed happiness to see me, an undergraduate student, to possess the interest to write and present the paper in such a big event. Some took out time to attend the session when I presented my paper afterwards and praised. I was advised to continue possessing my interest on all these. I received lots of encouragements and gained more confidence after attending this event which will help me in future.
