Premium OTT videos are safe from hacking thanks to forensic watermarking technology

Digital rights management (DRM) technology is used by over-the-top (OTT) platforms like Netflix and Amazon Prime to manage users and restrict access to premium video streams. It aids in the fight against piracy. DRM technology encrypts video assets using the AES format, which can only be decrypted using a licence key. In the event of piracy, this technology divides a video asset into blocks so that only one block can be decrypted at a time, minimising the damage. Nevertheless, the pirates have become more skilled over time. No matter how hard OTT platforms and content owners try, unauthorised users can still get their hands on high-quality premium HD content, which means content owners lose out on legitimate revenue.

nversions in DRM protected content are frequently exploited by hackers, particularly at the client level, which is also known as the user device. Decryption occurs at the end of a distribution chain, which provides an avenue for leakage of encrypted content. In this case, the device player receives an analogue signal. By using sophisticated algorithms, hackers are able to capture the video stream blocks as they are played back.

As a result of this, Hollywood studios are worried about losing millions of dollars in revenue from their expensive and slick movie content. DRM software developers have tried to fill in this security hole by incorporating video watermarking into their product line. As technology advances, so do the methods for inserting obscured text or codes into video frames, making them virtually invisible to the naked eye and virtually impossible to detect by recording software.

Forensic watermarking has four components: Each video frame will be encoded with a copyright or ownership message that will be decrypted using a secret watermarking key (a) and the host signal or video frame (b). video frame with watermarks.

Forensic watermarking requires that the ownership information remain intact throughout the entire video frame’s lifespan, even if the original video asset’s frame combinations are distorted by hacker activity such as resizing and re-encoding, transcoding, copying, or distribution. To combat piracy, the majority of major Hollywood studios are expecting OTT platforms to add not only multi-DRM measures but also a powerful watermarking option so that their anti-piracy teams can quickly discover how and from which users their premium content is pirated.’ Forensic watermarking and multi-DRM video protection are now being integrated into a single workflow by many multi-DRM SaaS providers to help OTT platforms meet Hollywood studios’ requirements.

As with most other online content sites, pirate websites charge for advertising space on their pages. Scammers frequently use branded campaigns to trick ad networks into displaying their ads. This strategy allows them to profit from both ad impressions and the number of times pirated content is viewed (if advertising is present within the audiovisual file itself).

At this point, content owners can track down piracy. forensic watermarks contain hidden information such as device ID, session ID, username, copyright information and more. When a video asset is leaked, content owners can use watermarks extracted from any frame of the video to identify the leaker and take appropriate action against them.
