US satellite broadcast service provider Dish Network is cracking down on online streaming piracy in many ways. In addition to litigation and other legal activities, the company looks at a wider range of situations. In a new patent application, Dish envisions a blockchain-based anti-piracy management system that promises to be open and accessible to everyone. "The inventor has conceived and simplified a software and / or hardware facility for content owners to claim content ownership so that copyright-friendly sites and services can effectively, efficiently and scalablely combat copyright piracy. Content owners provide watermark / fingerprint technology to embed identifiers in the content. The facility uses blockchain technology to add information related to each unique identifier in the database and allows authorized users (such as owners) to pass the block Chain transaction update information.
