A method for detecting against unauthorized transmission of digital works comprises the steps of maintaining a registry of information permitting identification of digital copyrighted works, monitoring a network for transmission of at least one packet-based digital signal, extracting at least one feature from the at least one digital signal, comparing the extracted at least one feature with registry information and applying business rules based on the comparison result.

A system and method for identifying media content presented over a media playing device. The media content, such as audio and/or video, is either available digitally or digitally sampled. The media content is sampled to generate a media sample or analytical representation of the media content. The media sample is compared to a collection of sampled (or represented) media content to identify it and to ascertain information related to the sample. This media content-related information is then presented to the user via a display means on the media player. The media player then presents the user specific and related actions that are based upon the information presented and allows the user to directly execute their choice of actions.

A system, apparatus, method, and machine readable medium are described for performing advanced authentication techniques and associated applications. For example, one embodiment of a method comprises: receiving a policy identifying a set of acceptable authentication capabilities; determining a set of client authentication capabilities; and filtering the set of acceptable authentication capabilities based on the determined set of client authentication capabilities to arrive at a filtered set of one or more authentication capabilities for authenticating a user of the client.

Advanced authentication techniques and applications

A system, apparatus, method, and machine readable medium are described for adaptively implementing an authentication policy. For example, one embodiment of a method comprises: detecting a user of a client attempting to perform a current interaction with a relying party; and responsively identifying a first interaction class for the current interaction based on variables associated with the current interaction and implementing a set of one or more authentication rules associated with the first interaction class.

A packet filter (2500) for incoming communications packets includes extractor circuitry (2510) operable to extract data from a packet, and packet processor circuitry (2520) operable to concurrently mask (3010) the packet data from the extractor circuitry (2510), perform an arithmetic/logic operation (3020) on the packet to supply a packet drop signal (DROP), and perform a conditional limit operation and a conditional jump operation (3030).

Ownership of a secure process is enabled with a cryptographic system. Methods initializing and operating the cryptographic system transfer control from the loading program to the loaded program and, in essence from the cryptographic system vendor to its end-user. As a result, ownership of the secure process can be relinquished to the end-user so that it alone can subsequently use the cryptographic system to control the secure process of loading and running its user-programs. The cryptographic system and methods allow for secure operations and protect against tampering with application software. The application program is retrieved from an encrypted file in external memory and authenticated by the cryptographic system before being executed.
