Sony announced Monday that it’s using blockchain technology for digital rights management (DRM), “starting with written educational materials under the Sony Global Education arm of the business,” reports Engadget. “This new blockchain system is built on Sony’s pre-existing DRM tools, which keep track of the distribution of copyrighted materials, but will have advantages that come with blockchain’s inherent security.” From the report: Because of the nature of blockchain, which tracks digital transactions in records that are particularly difficult to forge or otherwise tamper with, its application as a DRM tool makes sense and may also help creators keep tabs on their content. Currently, it’s up to creators themselves (or the companies they create for) to monitor their contents’ rights management. Sony’s system could take over the heavy lifting of DRM. The way blockchain works allows Sony to track its content from creation through sharing. This means that users of the blockchain DRM tool will be able to see — and verify — who created a piece of work and when. Sony Global Education is the current focus of the DRM tool, but going forward, the company hints that the rest of its media — including entertainment like music, movies, and virtual reality content — may be protected the same way.
