Secure Image was first copy protection solution for the Internet. Being encrypted and domain locked, the images cannot be saved or scraped because they cannot be displayed anywhere except on the owner's website. However as web users learned about PrintScreen and many different screen capture softwares evolved, Copysafe Web became the solution for copy protection from all avenues of exploit.
But Copysafe Web, being based on image encryption is no longer popular because other solutions like ASPS, Safeguard Media and Guest Video provide real copy protection with DRM options for all media including text, images, PDF and video.
Secure Image software is still available and with support for anyone still using it or wanting to use image encryption with Domain Lock.
