Medical Image Encryption Using Modified AES

In recent years mostly all the health centers and hospitals use the wireless networks and internet for biomedical information exchanging, the secure of this information in not verified and cannot be grantee in such environment, the personality of patient and for security concerns inside such institutions there is a need for encryption system that can easily encrypt the biomedical data and it can be shared with other centers via internet without and concerns about privacy. Our system based on modified advanced encryption standard (AES), with encryption and decryption in real time taking to consideration the criticality of data that been encrypted.
