Japanese know-how big Sony is taking a look at utilizing blockchain to retailer digital rights knowledge.
In an application revealed Thursday by the U.S. Patent and Trademark Office, Sony explains that present digital rights administration (DRM) options that goal 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.”
A blockchain might retailer the required identification info to make sure customers might watch the merchandise they buy, in line with the submitting.
DRM techniques seek advice from applied sciences that restrict entry to copyrighted supplies solely to those that buy entry. Sony cites UltraViolet, a cloud-based locker for digital rights, as one instance.
The software was filed collectively by Sony and subsidiary Sony Pictures Entertainment, and the doc particularly cites films for instance of the kind of media the system could possibly be utilized to.
However, Sony additionally argues the blockchain-based system might handle rights to “various types of content or other data, such as movies, television, video, music, audio, games, scientific data, medical data, etc.”
The software describes a number of potential implementations of the know-how. In one, every consumer’s rights are encoded on a devoted blockchain. This ledger begins with a genesis block, which shops figuring out details about that consumer. When the consumer acquires rights to sure content material – by buying a film obtain, for instance – these rights are dedicated to the blockchain.
Concurrently, a “DRM computer system would verify the rights in the blockchain and then decrypt the media when needed. This computer system can take different forms, including a “DRM agent” residing on a consumer’s gadget, in accordance with Sony.
