AN IMPROVED ALGORITHM FOR JOINT SELECTIVE MULTIMEDIA ENCRYPTION (JSME) - A PRIVACY ENHANCING STRATEGY

To provide security in network is a global issue in cyber world as we all know in the age of universal electronic connectivity, of viruses, attackers and hackers of electronic eavesdropping there is indeed no time at which security does not matter. So, to provide security against the hackers or threatens becomes a critical issue. This paper discusses about the various different encryption algorithms that can be uses in various different disciplines viz. image encryption, audio encryption and video encryption. This paper designed a new algorithm for JSME that is termed as Joint Selective Multimedia Encryption whose purpose is to provide security of confidential information within small duration of time. The significance to use the concept of selective encryption is it provides a high level of security and consumes less time as well. The Practical use of this new designed methodology is to provide security to online video conferencing. The complete working of this new designed methodology is depends on three step encryption algorithm used for cyber security (3SEMCS). The parameters consideration during applying image, audio and video encryption is important factors.
