How forensic watermarking fills the void left by a multi-DRM approach in tracing the source of a leakage
In order to ensure the safe delivery of content to the user's player and ensure that only verified browsers and players can access premium content, digital rights management solutions are required. To keep content safe from piracy or limit the number and type of devices that can access it, digital rights management (DRM) technology uses codes. DRM technology, on the other hand, can do little to stop piracy and illegal distribution or identify the source of leakage once the content reaches the user device.
The original video must be identified in order to secure DRM protected content outside of legitimate service providers. To put it another way, the infringing users or commercial pirates must be tracked all the way back to the last legitimate point of access. Video watermarking for forensic purposes enters the picture here. When using watermarking, the identification data (such as IP addresses, subscriber information, and session information, for example) is permanently embedded in the video. At the point of origin, the CDN (content distribution network) during distribution, or on the client device, the watermark can be inserted.
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.
