Multi-DRM vendors make it easier to protect premium video content from piracy

Digital rights management and forensic watermarking technologies have aided OTT platforms like Netflix and Amazon Prime in their meteoric rise to prominence. While the former allows OTT players to securely manage their users, the latter inserts undetectable data into video frames to track the source of leakage if pirates manage to break through the DRM system. 

Video content must be encrypted using DRM systems approved by major corporations because of the fragmentation among leading players in the market. Multi-DRM SaaS vendors have risen as a result, allowing video content to communicate with licencing servers owned by different corporations. The multi-DRM vendor provides both DRM video watermarking services. 

OTT platforms stream content to users' devices 24 hours a day, seven days a week. When a client device requests playback of DRM-protected content, the OTT website first authenticates the user's credentials. A DRM licence is then requested by the client devices for the specific piece of video content. If the device is an Android or Apple device or a browser, the multi-DRM vendor authenticates the licence from the  Google Widevine, Windows PlayReady, or Apple FairPlay licencing server. Encryption and decryption in the distribution chain can be coordinated through the multi-DRM vendor, which is where video files are encrypted in the final stage. 

When a video is queried, the multi-DRM vendor inserts undetectable data into each video frame, which contains information about the user ID, session ID, query time, device ID, etc., at the encoding level. A forensic watermark is what you're seeing here. In the OTT cycle, a robust watermark travels throughout the distribution chain and on each device. If you pirate a video, you'll still see the watermark in the pirated version. When the owner of the content discovers an illegal video, it can remove this watermark to determine where the leak originated from. 

Both the DRM licence and the forensic watermark are restrictive in many ways, allowing OTT players to reap the most benefit from their purchases. Although securing streaming video appears to be a complicated process, the multiple DRM technology handles it in a single, integrated workflow. In addition, because it is available as a SaaS, content creators can access it at any time, from any location.
