Technique for Security of Multimedia using Neural Network

With the increased popularity of multimedia applications, there is a great demand for secured data storage and transmission techniques. Security is a prevalent concern in information and data systems of all types. In order to satisfy secure multimedia data transmission between sender and receiver, this paper proposes technique for Security of Multimedia using Neural Network. Since the encryption process is one way function, the artificial neural networks are best suited for this purpose as they possess features like high security, no distortion and its ability to perform for nonlinear input-output characteristics. To protect from attack, the paper introduces a Model for Cryptosystem Using Neural Network, which is of high security and low cost. Based on this model separate Encryption and Decryption Algorithm is presented. Also Training Algorithm for Multi-layered Neural Network is provided to hold secure multimedia data. The proposed work finds its application in medical imaging systems, military image database communication and confidential video conferencing, and similar such application. The results are obtained through the use of MATLAB 7.0.1.
