Microsoft’s new system, Argus: A Fully Transparent Incentive System for anti-piracy Campaigns, is based on the transparency element of blockchain technology, as the study’s title indicates. Argus is a trustless incentive system built on the Ethereum blockchain that seeks to safeguard data gathered from the open anonymous population of piracy reports.
There have been several inevitable challenges during deployment to maintain security despite complete openness. With a watermark technique described in the article, Argus allows backtracing of pirated material to its source.
Each report of leaked material includes an information-hiding process, often known as proof of leakage. No one except the informer will report the identical watermarked copy unless they possess it.
