REAL-TIME ANTI-PIRACY FOR BROADCAST STREAMS

摘要

Systems, devices, methods and computer program products respond to real-time piracy of broadcast streams. One method includes receiving requests from a requesting device for a plurality segments of a real-time content, where at least one of the requested content segments differs from another segment of the plurality of segments in at least one characteristic. In response to the request, a particular version of the requested segments is transmitted to the requesting device such that a unique sequence of the transmitted segments identifies the requesting device or a user or a transaction. A communication network is then monitored to obtain a disseminated version of the real-time content, and based on the at least one characteristic of the obtained real-time content, it is determined if the real-time content includes the unique sequence of segments, and if so, one or more actions are initiated to thwart further dissemination of the real-time content.

主权项

1. A method for thwarting unauthorized access to a content, comprising:
receiving requests from a requesting device for a plurality segments of a real-time content, wherein at least one of the plurality of the requested content segments differs from another segment of the plurality of segments in at least one characteristic; transmitting a particular version of each of the requested segments to the requesting device, wherein a unique sequence of the transmitted segments identifies one or more of: the requesting device, a user or a transaction; monitoring a communication network to obtain a disseminated version of the real-time content; determining, based on the at least one characteristic of the obtained real-time content, whether or not the obtained real-time content includes the unique sequence of segments; and upon a determination that the real-time content includes the unique sequence of segments, initiating one or more actions to thwart further dissemination of the real-time content.
