In today's world most of the communication is done using electronic media. Data security is widely used to ensure security in communication, data storage and transmission. Security of multimedia data is an imperative issue because of fast evolution of digital data uses the permutation step, taking from Data Encryption Standard (DES) algorithm. Theoretical analysis and experimental results prove that this technique provides high speed as well as fewer exchanges or transfer over unsecured network. Multimedia data security is achieved by methods of cryptography, which deals with encryption of data.
