  • Patent number: 10691830
    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.

  • Publication number: 20190012480
    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.

  • Patent number: 10045093
    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.

  • Publication number: 20160105719
    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.
