Ask HN: Will the new W3C EME DRM standard make pirates' jobs easier?

1 点作者 whitehat2k9大约 8 年前
The W3C is expected to ratify the EME (Encrypted Media Extensions) standard for DRM&#x27;ed video on the web. This will essentially provide content creators with a uniform, standardized way to protect their content as it&#x27;s delivered to consumers over the web.<p>However, wouldn&#x27;t standardization actually make it easier for pirates (as well as legitimate consumers who wish to download a copy) to capture content? For example, what prevents someone with a penchant for reverse engineering from interfacing with and&#x2F;or intercepting the media stream from the DRM module? What prevents someone from developing a modified web browser with the ability to directly download DRMed streams?

EME isn&#x27;t a DRM standard. It&#x27;s an API for passing over the keys to a DRM system. So no, it doesn&#x27;t make things any easier than the object tag ever did.<p>The DRM module doesn&#x27;t necessarily pass the content back to the browser if it&#x27;s an OS component (which it often is) - there may be a secure video path. Heck, in the case of Netflix&#x27;s 4K service, it appears the OS itself doesn&#x27;t even see the content, it&#x27;s entirely kept within the GPU in a secure area.<p>If the DRM system does pass back the content to the browser then you could stream rip it from the video path, but &#x27;twas ever thus. And it&#x27;s worth noting in those scenarios content providers only seem to allow non-full HD content to be shown.<p>There&#x27;s nothing in the EME specification that defines how a DRM CDM module works, so there&#x27;s nothing to help compromise one in the specification, and generally speaking for the last few years DRM systems have actually got pretty good at protecting their keys to prevent impersonation.
