Japanese Corporation Sony is exploring the possibility of using the blockchain to store information about digital rights.
A corresponding patent application filed in the Office of patents and trademarks of the United States. The solution is called “digital rights Management based on the blockchain” (Blockchain-Based Digital Rights Management (DRM)).
“Conventional solutions are not very reliable and can rely on one single point of failure. If the supplier or a storage system of rights goes out of business or otherwise fails, the user loses all purchased content”, — is spoken in the application.
A DRM solution based on the blockchain eliminates the need for third-party service provider, allows you to securely store necessary identity information and provides users with more control over the content.
The patent application was filed in conjunction with Sony subsidiary Sony Pictures Entertainment, so as an example, content that is applicable to the blockchain-is set to movies. However, Sony claims that the system can control the rights to “different types of content or other data, such as movies, television, video, music, audio, games, scientific data, medical data, etc.”.
Variants of using a blockchain-DRM variety, the application describes examples of several of them. In one of them each user is encouraged to encode in a separate blockchain. In the Genesis block identification information is recorded about the user. When he acquires any of the content, those rights are transferred on the blockchain.
Earlier, Sony has filed a patent application describing a user authentication system based on blockchain technology.
