Digital image scrambling algorithm based on orthogonal periodic real-number sequences
Huang Xianbo · Journal of Zhengzhou University of Light Industry · 2007
An image scrambling algorithm based onorthogonal periodic real-number sequence is proposed.The scrambled image can beobtained by transforming the original image and the orthogonal periodicreal-number sequence using FFT(fast Fourier transform) and inverse FFT.The simulation results show that the histogram of the scrambled image is random Gaussian distribution,and the data of the scrambled image has the characteristics of pseudo-random Gaussian noise.Then it can be transmitted and stored insecurity.
