A graphics engine may include a decryption device, a renderer, and a sprite or overlay engine, all connected to a display. A memory may have a protected and non-protected portions in one embodiment. An application may store encrypted content on the non-protected portion of said memory. The decryption device may access the encrypted material, decrypt the material, and provide it to the renderer engine of a graphics engine. The graphics engine may then process the decrypted material using the protected portion of the memory. Only graphics devices can access the protected portion of the memory in at least one mode, preventing access by outside sources. In addition, the protected memory may be stolen memory that is not identified to the operating system, making that stolen memory inaccessibleto applications running on the operating system.
