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.

Systems and methods for performing semantic analysis of media objects

A multi-source bridge content distribution system links multiple content owners with access network operators or content distribution providers leasing space on access networks so that multi-media content can be provided from multiple content owners to consumers through a multi-source bridge or data center. Content files and associated content owner preference settings are provided from a plurality of content sources or providers to the multi-source data center. Files stored at the data center or locally at an access network are provided to subscribers through the local access network Content files are provided if the content owner preference settings are a sufficient match with service provider access network preference settings set up by the service provider using the access network to provide content to subscribers.

Multi-source bridge content distribution system and method

Digital content files containing entertainment media such as movies, TV shows, and the like are distributed from at least one content source primarily responsible for the original creation of the media to subscribers over a network system. The content source is connected over at least one content source network to a plurality of distribution partners, and each distribution partner is connected with a selected group of subscribers over an access network. A requested digital content file is distributed from the content source to a subscriber in a network distribution path comprising at least the content source network, the distribution partner associated with the subscriber, and the second network. A profile information package containing subscriber preferences is transmitted from the subscriber to the content source by way of a proxy over the network distribution path, and the profile information package is stored at the content source.
