Abstract
In this article, we have developed a chaos base visual encryption mechanism which can be applied in the electrocardiogram (ECG) medical signal. A main idea for using chaos sequence is to increase the un-predication compared with other kind of random sequences. Thus, we based on a values mapping of 1D chaotic scrambler and a permutation scheme to achieve ECG visual encryption. A way to realize the visual encryption mechanism is to scramble the signal values of the input ECG signal by multiplying 1D chaotic signal to randomize ECG signal values, and then a chaotic address scanning order encryption is applied to the randomize reference values. Simulation results show when correct deciphering parameters are put in, the signal will be completely recovered, and the mean square error value e is 1.5849×10−29. As long as there is an input parameter error, for example, with 0.00000001% initial point error, it could make chaotic array, and the ECG medical signal will not be recovered back.
