Sony Tries Using Blockchain Tech For Next-Gen DRM (engadget.com)
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.
Didn't they all learn - - from the BMG-Rootkit scandal - about piracy being a service problem - about tamper-protections only hurting paying customers before?
Only SONY can take a technology intended to increase freedom, and turn it into a method of censorship! Good gawd! this company disgusts me. I stopped buying their products when they started putting malware on DVD's they were selling customers.
Repeat after me, folks: Blockchain is a buzzword for a logbook.
That's it. There's no "inherent security". It's just a log with a checksum. Any can tamper with that log as much as they like, just making sure that they control enough of the verification process to authoritatively say their claims are genuine.
Seeing and verifying "who created a piece of work and when" is not really ever a problem in copyright cases. The real problems are how much of a pre-existing work was used or referenced to make a derivative work, and whether the derivative work is sufficiently creative enough to stand on its own.
With so little detail, it's difficult to speculate on precisely how Sony thinks this technology will benefit anyone (including themselves). So far, the only people who benefit from industrial use of a blockchain are the people selling a blockchain as a solution.
You do not have a moral or legal right to do absolutely anything you want.
But that makes zero sense. If they wanted, if there is real incentive, it is going to be trivial for some pirates to spin up a ton of servers to quickly perform a 51% attack. Or do you think sony is just going to spend millions of dollars having hash farms sitting there hashing away just in case a pirate attacks?
And more importantly, in the event the pirates successfully pull off a 51% attack, then what? Is everyone just going to roll over and say "well, the majority of hashing power has voted" and just give up on the ? No, they are going to say "well, that's not really valid anymore, so lets just ignore it and go with what sony says is legit". And now you've just invalidated the entire point of having a blockchain. "We can't trust anyone, so we'll trust the blockchain collectively...until we decide we can't trust the blockchain, at which point we'll just trust the entity we didn't want to simply trust at the beginning".
If you give up on your principles as soon as they are inconvenient, they weren't really principles to begin with. Likewise if you can stop trusting the blockchain as soon as you think it is compromised, it was never really trusted to begin with.
