Digitization and increased internet penetration have made the world a smaller place. It just takes a few hours for a film or show that has been released in one area of the world to go viral in another. Streaming material has made it imperative for creative companies to deploy comprehensive security measures in order to prevent piracy. DRM protected content and forensic watermarking are helping content companies prevent unauthorised access to audiovisual assets as well as dissuade and monitor piracy. “geofencing” can also be used by content owners to limit and optimise programming in distinct geographic regions.
Video assets may need to be restricted to certain regions in order for content providers to make money. If this is a security measure, it could be because they only have video licencing rights in certain regions and want to prevent the movies from being viewed outside of those regions. Geofencing is a term used to describe the practise of preventing movies from being seen in specified geographic areas.
Using geofencing, studios can time-shift the release of their content to cater to specific regional markets. As an example, a studio may want to offer a movie at a lower price or package it differently for a specific location. As a result, a bandwidth crisis is avoided because only relevant users see translated material. An IP address subnet is used to limit digital media in geofencing. Using a unique IP address, the local ISP (internet service provider) binds each device to the user’s actual location. You can prevent others from seeing the movie by blocking their access to specific IP addresses.
When it comes to pirated content being available in certain areas of the world, however, this logic is often defied. This is where video watermarking comes in. Forensic watermarking can be used in conjunction with geofencing techniques to monitor content leakage. The premium content’s watermark can be retrieved and identified by a watermark detector in the event of piracy to pinpoint the exact point of leakage. In this way, the vulnerable distribution routes or malicious users can be targeted and dealt with appropriately.
Because Google and Apple together cover the vast majority of mobile devices, applying Widevine and FairPlay DRM solutions to each video asset can make it secure and playable on the vast majority of these devices as well. As an alternative, content owners may use proprietary DRM systems, such as those hosted on self-hosted servers, to build their own video libraries.
