Resilient Rights Protection for Sensor Streams

Today’s world of increasingly dynamic computing environments naturally results in more and more data being available as fast streams. Applications such as stock market analysis, environmental sensing, web clicks and intrusion detection are just a few of the examples where valuable data is streamed. Often, streaming information is offered on the basis of a non-exclusive, single-use customer license. One major concern, especially given the digital nature of the valuable stream, is the ability to easily record and potentially “re-play” parts of it in the future. If there is value associated with such future re-plays, it could constitute enough incentive for a malicious customer (Mallory) to duplicate segments of such recorded data, subsequently re-selling them for profit. Being able to protect against such infringements becomes a necessity. In this paper we introduce the issue of rights protection for streaming data through watermarking. This is a novel problem with many associat...
