How to trust your player: Building an OTT service for today’s world

Prevent attacks against the DRM license acquisition servers. Make sure only verified browsers and players can access the media and DRM license in different devices.

Consider that hackers have honed their technical skills to develop and adopt new ways of defeating defenses and responding to detection with new brands and sites. The least technically sophisticated approaches that pirates use to get around the robust protection of sophisticated ott drm systems include high-quality camcording from 4K UHD TV displays. Advanced methods, similar to those of professional pirates, include high-bandwidth digital content protection (HDCP) strippers.

An integral part of content packaging is the insertion of DRM signaling in the media, such as the common encryption Protection System Specific Header (PSSH). Because the content packaging and playback workflows need to coordinate the DRM signaling and Content.

Encryption Keys (CEK), it is critical that the content packaging workflow and the multi-DRM system are tightly integrated. The content packager needs to retrieve the CEK from a multi-DRM service provider that manages these keys securely.
