Abstract: Systems and methods for preserving privacy in distribution of content using private tokens in accordance with embodiments of the invention are disclosed. In one embodiment, a method of anonymously tracking a digital content and remediating unauthorized distribution includes generating a private token including an identifier distinguishable from tokens generated by other playback devices and the association with the playback device is not shared, receiving a portion of content, embedding a digital watermark in the content, where the digital watermark includes the private token, detecting an unauthorized copy of the content, extracting the digital watermark from the unauthorized copy of the content, broadcasting an enforcement message containing the private token to the playback devices, receiving the enforcement message, and performing an enforcement action on the playback device in response, where only a playback device that generated the private token responds.

Abstract: Systems and methods for securing communications in a playback device using a key base and at least one key contribution in accordance with embodiments of the invention are disclosed. In one embodiment, a process includes generating a key base using a decryption key and at least one key contribution, where the decryption key can be recovered using the key base and the at least one key contribution, receiving the key base, receiving the at least one key contribution, sending the key base to a decryption module, sending the key contribution to a control module, performing a control feature on the piece of content using the control module, providing the key contribution to the decryption module when the control feature is performed, generating the decryption key using the key base and the at least one key contribution, and accessing at least a portion of the piece of content.

Abstract: Systems and methods for retroactive assignment of personally identifiable information in distribution of content in accordance with embodiments of the invention are disclosed. In one embodiment, a method of controlling anonymity of user profiles includes generating an intermediate identifier using a playback device, where the intermediate identifier is random and different from intermediate identifiers used by other playback devices and is not known to be associated with the playback device by entities other than the playback device, sending the intermediate identifier associated with consumption data concerning content files that have been accessed on the playback device to an audience measurement server, aggregating the consumption data into an anonymous user profile, sending personally identifiable information about a user of the playback device to the audience measurement server, and combining the personally identifiable information about the user with the anonymous user profile.

Abstract: Systems and methods in accordance with embodiments of the invention enhance the security of content distribution using individualized playlists. In many embodiments, a playlist is individually composed for a client device so that the selection of content included in the playlist encodes information. One embodiment includes generating a watermark sequence, where each watermark sequence is a unique identifier, selecting between alternative chunks of encoded content based upon the watermark sequence, where each of the alternative chunks of encoded content includes the same perceptual content and differs in the way it is watermarked, and listing the selected chunks in a playlist, where content assembled using the playlist includes a unique watermark sequence.

Abstract: Systems and methods for rapid content switching between pieces of content presented in a plurality of stations using streaming content distribution in accordance with embodiments of the invention are disclosed.

Abstract: Systems and methods are disclosed that authenticate devices or users, and enable playback of secured streaming content through a media player. In one embodiment, the invention is a system for receiving secure content over an unmanaged network, including a security application configured operate on a user device with access to a network, where the security application is configured to receive a request for playlist data from the media player, send a playlist request to a content server, receive playlist data from the content server, send playlist data to a media player, receive a security access request from the media player, send a security access request to a security server, receive security access data from the security server; and send security access data to a media player.

Abstract: Systems and methods for collecting audience measurement data using content protection signaling messages while playing back content are disclosed.

Abstract: System and method for identification of ownership to media objects through analysis of semantic information in the media objects are disclosed. Semantic information is a term that can be used to describe aspects of the content of a media object that are apparent to a human viewing or listening to the content. In many embodiments, the media object is analyzed for semantic information that are indicative of media ownership such as, but not limited to, station identification logos, franchise logos (e.g., the title credits of a popular television series), theme songs, the distinctive voice of a news presenter, the face and/or voice of an actor and/or other characteristics of the media object are used as a basis for determining entities associated with the media object.
