Sony the technology giant based out of Japan is looking to store digital data using blockchain technology.
On Thursday, U.S. Patent and Trademark Office published an application that explains Sony’s current digital rights management (DRM) solution which aims for interoperability “may not be very reliable and rely on one unique point of failure and if the rights locker provider or system goes out of business or otherwise fails, the user loses all the acquired content.”
According to the patent filed a blockchain would help in storing the identification information which would ensure users could watch the products they buy.
DRM systems is a technology that limits the access to copyrighted material and those who purchase the product will be able to access it. One example is Sony’s UltraViolet a cloud-based locker for digital rights.
Sony and its subsidiary Sony Pictures Entertainment jointly filed this patent application. Sony specifically focuses on movies as a type of media this system could be applied to.
Sony also believes that blockchain technology-based system could manage the rights to not only movies but also television, music, video, games, medical data and scientific data, etc.
The patent application explains various potential uses of the technology. One of the implication is that each user’s rights are encoded on a dedicated blockchain. Every ledger begins with a genesis block which stores information about a users identification.
Every user’s rights are committed to the blockchain and they acquire these rights by purchasing the content.
