Techniques for enforcing a depth order policy for graphics in a display scene

Abstract

Various embodiments are generally directed an apparatus and method for processing an encrypted graphic with a decryption key associated with a depth order policy including a depth position of a display scene, generating a graphic from the encrypted graphic when the encrypted graphic is successfully decrypted using the decryption key and assigning the graphic to a plane at the depth position of the display scene when the encrypted graphic is successfully decrypted.
