System and method for enabling device dependent rights protection
Abstract:
A system and method for enhancing the protection of digital properties while also increasing the flexibility of distribution of the digital properties. In one embodiment, the digital property is protected through the binding of at least one unique client device identifier with the digital property prior to distribution. Decryption at a client device would therefore be dependent on a comparison of the unique client device identifier that is extracted from the encrypted digital property with a unique client device identifier of the device that is seeking to access the digital property.
