Medical Image Encryption Algorithm Based on Chaotic Function
Junjie Zhang, Jun Zhe Tan, Yun Cheng · 2017
The problem of image encryption on the telemedicine platform was discussed in this paper. The Arnold algorithm was introduced firstly, then based on the analyzing of those advantages and disadvantages in the encryption algorithm, a modified encryption algorithm was proposed by using the sensitivity of the initial value and the internal randomness of chaotic functions. Finally, effect evaluation was made on the image encryption algorithm of chaotic functions by introducing coherence from the horizontal, vertical and diagonal directions. Experimental results show that the correlation of encrypted image with the proposed algorithm is lower than the Arnold algorithm.
