Abstract
The main purpose of image compression is to reduce the memory space or transmission time and that of cryptography is to keep the security of the data. These two technologies are separate. But in some cases an image can be compressed if necessary, and then encrypted. To encrypt the compressed data and for transformation function many techniques are used in several areas. In this work, some of the Discrete Wavelet Transform based methods are discussed and a comparative study is performed between these methods. Then states the advantages of Discrete Wavelet Transform. Out of these methods Resolution Progressive Compression provides the best features.
