Sony, a Japanese tech giant, intends to use blockchain to store Digital Rights Data. According to the application published by the U.S. Patent and Trademark Office on Thursday Sony tries to explain that current digital rights management (DRM) solutions that aim for interoperability "may not be very reliable and rely on one unique point of failure. If the rights locker provider or system goes out of business or otherwise fails, the user loses all the acquired content."
The application describes that a blockchain can store the required information of identification that ensures consumers can view the products they purchase.
DRM systems are the technologies that limit the access to materials which are copyrighted to the users who purchased the access. Sony quotes UltraViolet, a cloud-based locker for digital rights, as one good example.
The application was jointly filed by Sony and its subsidiary Sony Pictures Entertainment with the document specifically citing movies as an example of one kind of media, the said system that could be utilized for Digital Rights Data.
The blockchain based system can manage rights to "various types of content or other data, such as movies, television, video, music, audio, games, scientific data, medical data, etc." Sony states.
Sony has already been exploring various other applications of the blockchain technology such as, for authenticating user data and managing education data.
