Digital rights management and forensic watermarking technologies have aided OTT platforms like Netflix and Amazon Prime in their rise to prominence. If pirates manage to get past the DRM system, they can use one of these methods to track the source of leakage, while the latter inserts undetectable data into video frames.
Video content must be encrypted using DRM systems supported by major corporations because of the fragmentation among leading players in the industry. As a result, multi-DRM SaaS providers, which allow a piece of video content to communicate with licencing servers owned by various corporations, have emerged. Video watermarking and digital rights management (DRM) services are available from the same vendor.
An always-on model is used by OTT platforms to deliver content to users’ devices. The OTT website authenticates the user credentials whenever the client device requests playback of DRM protected content. Requests for a DRM licence are then made by client devices for the specific piece of video content. Google Widevine, Windows PlayReady or Apple FairPlay licencing servers are used to authenticate the licences of Android and Apple devices and popular browsers respectively. Because the video file is encrypted at the end of the distribution chain, the multi-DRM vendor serves as a node to coordinate both the encryption and decryption processes.
When a video is queried, the multi-DRM vendor inserts imperceptible data into each frame of the video that carries information about the user ID, session ID, time of query, device ID, etc.. A forensic watermark is what you’re looking at. The OTT cycle’s distribution chain and each device carry a robust watermark. Watermarks are permanently embedded in pirated videos. When a video’s owner discovers an illegal copy, they can use this watermark to track down the leak.
Due to the numerous restrictions imposed by the DRM licence and the forensic watermark, online video distributors (OTTs) can get the most out of their investments. Although securing streaming video appears to be a complicated process, the multiple DRM technology handles it in a single, integrated workflow. The SaaS model allows content creators to access and use the software on-the-fly, no matter where they are located in the world.
