Paper Abstract

This paper describes how to integrate encryption in an algorithm which uses wavelets to compress data. Wavelets are more useful in image compression than other methods. This is because the definition about which data should be left out is more flexible. This adaptation of wavelets to specific features of images leads to acceptable results. The use of computers in image transfer will increase further and it will therefore become necessary to transfer image data quickly. In addition, a protection of the image against unauthorized access will become necessary. Image compression increases the amount of time needed for transferring an image. Regarding the area of telemedicine, there is a demand for the protection of images. The reason for this demand is the need to prevent the relationship between patient data and an image from being determined. Therefore, the approach intends to describe a combination of image compression by using wavelets and to integrate encryption into the wavelet- transform and -compression procedure.
