Secure An Image

[Anonymous]

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?

Any ideas....


thanks

The simple way what i feel is do water mark to your images.. You can do it by using either Photoshop or any other image editing tool.

If you want any help in Photoshop kindly visit below website, where i have posted Photoshop articles.

watermark doesnt help...

the images are some kind of important info like account figures and etc, only allow to view, not to copy. So if watermark was use, either the info cant be view because watermark might block or blur ceertain part, which the data will be useless.

What i need is to secure it from download....

Any suggestion ??

thanks

You _CANNOT_ secure an image or prevent it from being downloaded based upon this one very simple train of mind.



That image, is on your server.
If you want your client to view this image, it *MUST* be transferred to your client's computer.

ie.. it gets downloaded WHENEVER it is viewed.
And therefore, is cached in the temp files of the browser.


Keep in mind, the only data that is 100% secure, is the data that doesn't exist.
Everything else is fair game.
