基于DWT-SVD和DSP的数字图像加密算法实现
IMPLEMENTATION OF DIGITAL IMAGE ENCRYPTION ALGORITHM BASED ON DWT-SVD AND DSP
摘要
Abstract
In order to solve the security problem of digital images in communication channel transmission, we propose a new digital image encryption algorithm based on DWT-SVD. Singular value of the image has good irreversibility against the geometric attacks, and after mathematical transformation, the image centroid will not change. Based on the above analyses, in this paper we dwell on the designing idea of the DWT-SVD algorithm, and present the implementation steps of the algorithm. The DWT-SVD algorithm could be implemented on the constructed platform of image processing system based on DSP, and through the experimental test we can find that the DWT-SVD algorithm could well fight against geometric attack in communication channel, thereby ensure the security, invisibility and robustness of the images transmitted in the channel.关键词
