Abstract: An audio/video distribution system with enhanced digital rights management. configured for use with a source of programming, a third party responsible for authorization, and an audio/video output device at a recipient location, includes a source encryptor and a receiver and authentication device disposed at a recipient location. The source encryptor is responsible for transmitting the programming (including any applicable plus policies, rights and/or rules) in encrypted form with missing content to the recipient location. The receiver includes an input for receiving the programming, a decryptor, an output for delivering the programming to the audio/video output device, a bi-directional link for communicating with a third party authenticator, a sensor for receiving a programming request from the programming request device, and a processor.

Abstract: An autonomous and portable smartcard reader device incorporates a high level of embedded security countermeasures. Data transfers are encrypted with two specific input devices, namely a light sensor and PIN or other keyboard entry, and at the output through the use of a dual-tone encoder-decoder. The unit may be used alone or as a plug-in to another device such as a PDA, cell phone, or remote control. The reader may further be coupled to various biometric or plug-in devices to achieve at least five levels of authentication, namely, (1) the smartcard itself; (2) the smartcard reader; (2) the PIN; (3) private-key cryptography (PKI); and (5) the (optional) biometric device. These five levels account for an extremely strong authentication applicable to public networking on public/private computers, and even on TV (satellite, cable, DVD, CD AUDIO, software applications. Transactions including payments may be carried out without any risk of communication tampering, authentication misconduct or identity theft.
