    Image copy pervention

    Hi all,
    Is there any way so that no one can copy the images which i burnt in my CD? Is there any specific property for Images?

    You can not protect it through the FileSystem, because to view images, you will need reading rights, and that alse enables you to copy them

    One way of doing it, could be. That you encrypt the images with an encrypting program like PGP, and create your own viewer for viewing the images on the CD. That way, if a user copies the images directly from the CD, thay can't use the images in any viewer.

    You view will ofcourse know the code, and hence it can decrypt the file and show it to the user.

    If your application shows these pictures on the screen, the user can still do a PrintScreen to copy the pictures.
    I once saw a tool that protected images from being copied with PrintScreen, but that completely messed up other programs functionalities (eg. the bitblt API function didn't work anymore).
    I don't know the name of this tool anymore, I immediatly removed it from my system.
