The video streaming market has to deal with the constant threat of sophisticated piracy attempts on premium video content. Multi-DRM and forensic watermarking solutions are preferred by OTT platforms and major Hollywood studios in order to authenticate users and track piracy, respectively.
It’s true that OTT platforms have to manage their IT infrastructure around the world, which puts a strain on anti-piracy measures and causes a slew of technical difficulties. These measures can be taken to protect against global attacks and ensure smooth delivery of video content for users across geographies when using video watermarking techniques on a content delivery platform:
- Maintain a small storage and bandwidth footprint for metadata files on the delivery platform. So that the forensic watermarking platform can reliably identify a video file’s intended recipient, the edge server should store the metadata associated with the file. Both the server and the client benefit from using metadata instead of duplicating a file because it is more efficient in terms of resources used.
- Bitstream-based watermarking technology should be used instead of the A/B variant option for cache optimization. Caching of a single variant of the video asset by the CDN can be optimised with a longer life, resulting in a faster transmission rate.
- The embedding process should be streamlined, as speed is of the utmost importance in the streaming market. After submitting a query, no one wants to sit around and wait for the video to buffer. Adaptive bitrate segmentation and a vendor that inserts watermarks in single chunks should be selected by the delivery platform for faster watermarking.
- It is more difficult to attack a server than a client device, so the delivery platform should make sure that all critical operations of watermark embedding in DRM protect content take place on the server.
Through the use of multi-DRM, these precautions can improve asset security as well as speed up the watermark embedding process. Using a cloud-based watermark extraction service that works well even with low-quality and recompressed videos, it is possible to verify the owner of the content and track down the source of the piracy. Client-side watermarking, A/B or manifest-level watermarking, and bitstream-based watermarking are three broad categories of watermarking solutions.
An effective video watermarking service must be able to deter piracy, identify the piracy outlets, and take the necessary steps to prevent leakage of the video content. In order to detect piracy, keep an eye out for suspicious activity and compare the digital fingerprints of suspicious files to the production fingerprint. The watermarking software is then able to identify the watermark and extract the information contained therein. Resize and collusion attempts, for example, shouldn’t affect the robustness of the watermark. It should also remain legible even after the content has been altered. It’s also possible to take legal action after discovering the source of a stream that is being illegally downloaded.
