Improving the security of images transmission

The security of images transferred via internet is very important issue. The proposed system tries to satisfy all requirements of security to ensure that any medical image related to any patient do not allow to be accessed via any unauthorized person. We can use an encryption scheme for encrypt medical image. Only the authorized person can decrypt this medical image and can obtain the original image. The ownership of these medical images is very important to improve. We can identify the ownership of any medical image by using watermark related to the owner of this medical image. We used name of the patient and serial number. Capture the ear image of the owner then extract features from ear after that encrypt those features then used it as watermark. The size of the medical image is very effective point in transmitting via internet. Because of this the proposed system used mix of compression techniques applied on medical image before sending via internet. Run time is very important in any system and complexity is very important aspect in computer science. To reduce run time and complexity of the proposed system, we can use DWT to separates an image into approximation image LL, HL LH and HH.
