Sony looking at using blockchain for digital rights management

Tech giant Sony wants to use blockchain to store digital rights data, a new patent application published this week has revealed.

The company reasons that the current solutions for digital rights management (DRM) are unreliable because they often rely on a single 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.”

Sony envisages using this technology to manage rights to various content and data such as movies, television, video, music, audio, games, scientific data, medical data and more. The patent application was jointly filed by Sony and Sony Pictures Entertainment.

Th technology would work by encoding users rights on a dedicated blockchain using a genesis block. When a user purchases a film or game, their rights to said content would be committed to the blockchain.

Sony said: “A DRM computer system would verify the rights in the blockchain and then decrypto the media when needed. This computer system can take different forms, including a ‘DRM agent’ residing on a user’s device.”
