发明名称 Digital-rights management system
摘要 Devices (101) are assigned a unique, unalterable, identification or serial number (313) that acts as the devices "electronic" biometric. Any certificate (302) created by a key issuer will contain the device's assigned DRM public key and the device's electronic biometric data. When a consumer wishes to purchase new content (304) from a content provider (103), the consumer will send the DRM certificate containing its DRM public key and the biometric. The rights issuer will then create a license (306) that assigns the content in such a way that only a device with the particular biometric and DRM private key is allowed to render the content.
