The Japanese tech giant has shown interest in the use of blockchain technology to store identification information. This was seen in an application published on Thursday the 26th of April 2018 by the U.S. Patent and Trademark Office showing that users will be able to keep track of all the products acquired when stored on the blockchain. This isn’t the first time Sony has shown interest in the use of the technology. They have been looking at other applications including “authenticating user data”and ”managing education data”
Sony made it clear that current digital rights management (DRM) solutions that aim for the ability of computer systems or software to exchange and make use of information “may not be very reliable and rely on one unique point of failure. If the rights locker providers or systems go out of business or otherwise fail, the user loses all the acquired content.”
However, in a welcomed development, the blockchain could manage rights to “various types of content or other data, such as movies, television, video, music, audio, games, scientific data, medical data, etc.” says Sony.
Several potential implementations of the technology are stated in the application, one of which is the fact that each user’s rights are encoded on a dedicated blockchain. This ledger begins with a genesis block, which stores identifying information about that user. Rights to certain content are committed to the blockchain once they are acquired.
