I wanted to know is there any way to encrypt the stored image files so that if the files are accessed illegally that cannot be abused.
And secondly, is it possible that after x months , patient study is automatically compressed using any compression tool like Winrar or 7zip to save space. And when user try to retrieve any specific study , it must be retrievable also. These zip files must be password protected if any user try to open them. But if the user query it through conquest the server must bypass or ignore the password restriction form the zip file
