i have a situation here...
I trying to secure a pdf/image from user download from internet. User can view it using online web browser like IE and etc through some CRM.
I manage to convert the pdf to image, because PDF allow to print.
But then now i try to secure this images, but how?
I manage to disable right click, manage to disable print, disable print screen. Now all i need is to prevent user from getting the images in Temporary Internet Files.
- my idea was, i know can't stop the file from download to user Temporary Internet Files, but i need to secure it so user can't grap the file from that folder and must view from the online CRM
- encrypt the image? zip the image? imagemagic to edit it? crop? image stream?
