Image encryption technology based on DWT
Yue Liu · Computer Engineering and Applications Journal · 2010
This article sums up the image of the encryption algorithm and produce.24-Bitmap image encryption is implemented in DWT domain,the data sequences used for encryption are created from Lorenz chaotic system.The article performs a detailed comparison of the effect scrambling DWT coefficients at different scales for encryption,as well as the systematic analysis of the experimental result,finally points out a question using of wavelet coefficients for encryption,and also provides another method for the image encryption.
