  • Disney Patents Blockchain-Based Movie Distribution System to Stop Pirates

    I don't see what this gets them that the kdm setup doesn't already provide.

    Disney is one of the best known brands in the world and the owner of an impressive collection of movies and TV shows.

    New and old releases earn the company a healthy stream of revenue, both in movie theaters and through its own movie streaming service Disney+.

    While there is plenty of competition from other movie studios, Disney’s single biggest threat appears to be piracy. To tackle this issue, Disney’s in-house anti-piracy team works around the clock, and the company takes part in the ACE coalition as well.
    Disney’s Blockchain Anti-Piracy Patent


    Through these anti-piracy efforts, Disney has helped to take down dozens of piracy sites and services. However, the media giant is also trying to be more proactive. A newly awarded patent proposes a blockchain-based media distribution system that aims to prevent early piracy leaks.

    The patent in question, titled “Blockchain configuration for secure content delivery,” focuses on the distribution of content to movie theaters. This is a vulnerable process where pirates with the right connections can make copies during or after delivery.

    There are already several security mechanisms in place to prevent leaks from happening. Theaters have to adhere to strict rules, for example, and movies are all watermarked. Nevertheless, Disney believes that this isn’t sufficient to stop pirates.

    “[S]uch security mechanisms are often reactive rather than preventative. For example, watermarking configurations insert a watermark into content to track piracy after the piracy has already occurred. As a result, current configurations do not adequately prevent piracy,” the company explains.
    Verifying Rights


    Disney argues that by implementing a secure blockchain-based system, the distribution process can be more tightly controlled. Among other things, it will make it impossible for a movie to be played before it arrives at the intended location.

    “In contrast with previous configurations, the blockchain configuration verifies that the content is received at the intended destination prior to allowing playback of the content at that destination,” the patent reads.





    The system can also be configured with other anti-piracy features. For example, it can track the number of times a movie is played to prevent bad actors from showing it more often than they should.

    “Further, the blockchain configuration has an automated auditing mechanism that tracks playback of the content at the destination to ensure that the quantity of playbacks is accurately recorded. Therefore, piracy by the intended recipient, in the form of a greater quantity of actual playbacks than reported playbacks, is prevented.’
    Other Playback Environments


    While Disney regularly refers to movie theaters and projectors, it specifically states that the patent also applies to other ‘playback environments.’ For example, when Disney content is sent to other streaming providers, which will need the proper credentials to play the content.

    There are several possible practical implementations but whether Disney has concrete plans to use these in the real world is unknown. That said, it’s certainly intriguing to see that the company is seriously considering the blockchain.

    It is worth noting that this anti-piracy system is focused on the content distribution and delivery process. This will, in theory, help to prevent pre-release leaks. However, it won’t stop pirates from ripping movies and TV shows directly from Disney+.

    Disney is not the only media company that has an interest in blockchain technology. Earlier this year, DISH Network secured a patent for a system that online services can use to check if an uploader has the proper rights to share something.

    If you are going to release day-and-date...you're the pirate! You're putting in the hands of "who knows?"

    Why would anyone copy a movie in a theatre when they can get a digitally perfect copy with picture and sound streaming right on in.

      Some of these patents and press releases are only targeted towards shareholders and mean nothing for reality.

        The only thing I can think of is enhanced security over time, if the media block is constantly having to "phone home" to ask for permission to play a movie.

        We know that the DCI "budget" of six minutes a year for correcting a drifted media block clock can easily be overridden by manufacturers. Indeed, the ability to do this is absolutely necessary, because if a DCI system is installed without the server configured to sync to a NTP server regularly, the media block's secure clock will drift out of budget relatively quickly (though some more quickly than others).

        Barco and Dolby will send you a patch on request that will allow the clock to be reset without limit on the next reboot, if it finds a stratum 0 or 1 NTP to sync to. GDC are a bit more retentive over the process, and will only correct a clock by remoting in to the affected server. However, the mere fact that this ability exists is a potential security hole, albeit one that would require a dishonest and/or compromised employee at a hardware manufacturer to exploit. If a "master patch" - that allows you to reset the secure date and time to anything you like, over and over again - ever got out, then any KDM ever issued for that media block would effectively open the movie permanently.

          Even in this case, a blockchain implementation would not be worth the overhead. Simply checking if the time is "right" by matching it with a few "time servers", that send you a signed answer would be a far less complicated solution than running a blockchain.

          I guess the other advantage in this is that they can eliminate the middle-man, instead of paying something like Deluxe to distribute KDMs for you, you could now simply publish the KDMs to the blockchain, instead of sending out e-mails. This doesn't add anything particular to the security of the system though and it remains to be seen if a blockchain will be cheaper to run than distributing keys via e-mail.

          I guess, we could benefit more from a UNIFORM content publishing API and on-line distribution platform. Where you get a certificate and an URL and have your TMS or servers fetching the content automatically from the content publisher. If they're wise, they could even use a peer-to-peer protocol to reduce their bandwidth cost, just like the pirates do, they're trying to fight.

              Yeah, that document has been passed around here before. I guess it's a nice start, at least to automate the KDM side of things. The other part would be the actual content, the DCP itself.

              It looks like with Bitcoin's current roller coaster ride, the hype around blockchain is back. While blockchain can certainly be a solution, it often just isn't. Blockchain works best in a "distributed trust" model, where essentially nobody trusts nobody. While that may sound like your average Hollywood studio, it's not how DCI content distribution currently works.
