New Image Encryption using Chaotic Map in Wavelet Domain
, Kumar S, Gera R.
Published in IEEE
Multiple image encryption is the prime concern of data security technology due to prevalence of capacity in storage and data transmission. In our paper we have introduced three-level multiple image encryption technique which uses Robust chaotic map. Firstly, the input images are concatenated and undergo 2D discrete wavelet transform and the image that is obtained is composed of low frequency components. Then using Arnold map image is being scrambled. Following to which encryption key generated from RCM is diffused with scrambled image. Since each key is unique it becomes difficult to decrypt and get original data. Again, using Henon map the scrambling is performed to acquire encrypted image. Lastly the performance analysis is carried out to know the security level of the system using histogram, correlation coefficients and NPCR and UACI values. © 2019 IEEE.
