A Medical Image Encryption Scheme Using Chaotic Random Sequence

Abstract

Due to the development of internet and computer technology, most of the content exchange in network is image information which requires image transformation to ease the transmission. There is also lot of development happening on image encryption due to internet information attack, thus requires better image encryption algorithm. Chaotic technology with henon mapping is a recent image encryption technique which performs better than other algorithms. Because of randomness in ciphertext,chaotic technology reduces the unauthorized deciphering attempt.Hence recent digital image encryption considers chaotic technique as best secure image sharing technique.In the proposed method, the chaotic digital image encryption technology is used along with image transformation technique for better sharing and security of most valuable medical images. The experiment results discussed with the help of histogram,correlation, key size and sensitivity. The proposed work shows that security is better than existing techniques.
