A NOVEL APPROACH IMAGE SECURITY FOR PUBLIC NETWORK TRANSMISSION

Abstract

With the progress in Data Transmission by an electronic system, the need of security has Become necessity. Due to Exponential growth of multimedia application, security must be a high priority. Image application have been rapidly used in our digital media world. Some exiting algorithm provides security of image applications. There are different algorithm for image encryption with having different parameter like image encryption ratio, encryption- decryption speed, compression ratio and security level. With the rapid increase of very high speed wireless networking, the main objective to be controlled like efficient ,robust and secure encryption algorithm required. With the exponential growth of image exchange, security of information is the main concern when information store and transmission over the internet. The objective of encryption algorithm protect the information from unauthorized person. The application of image in field of milarity confidentail image transmission, medical image application and some image of confidential projects. The main objective of image encryption algorithm provides the three most important components are following confidentiality, integrity and authentication for image transmission over the public network. The primary objective of this algorithm to provide that high speed encryption and decryption of the digital image as compared than normal AES image encryption algorithm.
