Abstract: In general, embodiments of the invention include methods and apparatuses for securing otherwise unsecured computer audio and video subsystems. Embodiments of the invention perform watermarking of video and/or audio data streams output by a computer system. Additional security features that are included in embodiments of the invention include fingerprinting, snooping, capturing streams for local or remote analytics or archiving, and mixing of secure system content with local audio and video content.

Abstract: The present invention relates to methods and apparatuses for securing otherwise unsecured internal and external computer communications. According to one aspect, the invention relates to methods and apparatuses for implementing device gatekeeping. According to another aspect the invention relates to methods and apparatuses for encrypting and decrypting data sent over an external or internal interface. According to another aspect, the invention relates to methods and apparatuses for implementing device snooping, in which some or all traffic passing between a host and a connected device is captured into memory and analyzed in real time by system software. In embodiments, the software can also act upon analyzed information. According to certain additional aspects, the security functions performed by methods and apparatuses according to the invention can be logically transparent to the upstream host and/or to the downstream device.
