Using forensic watermarks as a component of its anti-piracy defence strategy
The Edge server minimises the possibility of unauthorised copying of premium over-the-top content by embedding forensic watermarks into its anti-piracy defence system. This prevents the distribution of pirated versions of the content.
It is more important than it has ever been for businesses that provide video on demand and over-the-top services (also known as VOD and OTT) to protect their content against unauthorised use and disclosure than it is right at this very moment. In fact, it is more important than it has ever been to do so. As an additional method of discouraging illegal streaming, the utilisation of digital rights management (DRM) protected content has attained universal appeal among content creators and distributors. DRM stands for digital rights management. The term “DRM” is an abbreviation that stands for “digital rights management system.” DRM refers to the management of digital rights. This is done with the goal of avoiding illegal streaming and minimising any damage that may arise as a result of it. With the help of watermarking, you will be able to distinguish between the video streams that are associated with each individual viewing session and the video streams that are associated with other sessions. There are a variety of techniques for adding a watermark to an image, the most prevalent of which being bitstream modification, A/B watermarking, and watermarking done on the client’s side. The process of watermarking is also capable of being completed in a variety of additional methods.
Any streaming player or device is capable of implementing session-based watermarking, which ensures that each unique user receives a one-of-a-kind copy of the video. This type of watermarking can be of immense utility, as it can be applied to any streaming player or device. Any streaming player or device is capable of having session-based watermarking applied to its content. Since all streaming sessions are sent from the edge of the CDN, it is possible for the edge server to perform the functions necessary for video watermarking. This is made possible by the fact that all streaming sessions are delivered from the edge. The most recent development in watermarking technology has made it possible for service providers to directly insert a watermark into an encoded bitstream. This has been made possible by the fact that the technology has advanced. Before the content is sent out to end users, the edge server will first create a unique identity for each individual piece of content during this phase of the process.
The following are a few examples of anti-piracy processes that can be put into action with the assistance of an edge server:
Before beginning the watermark pre-processing, the video asset that will be transmitted is first given the ABR transcoding treatment. This occurs before the beginning of the submission process. This approach of video analysis, which locates potential transition points in the video stream, is helpful in simplifying the process of encoding a WMID. It does this by identifying the places at which the video stream might change (Watermark Identifier). The information that was acquired from this analysis is added to the metadata and encoded while the bitstream is being packaged. This step takes place throughout the packaging phase.
It has been determined that the token for the watermark has been delivered: Before beginning each individual viewing session, the video player will first check to see if a WMID has been supplied in any capacity. A JSON web token that is likewise capable of performing the functions of a WMID will be generated by the platform management subsystem of the content provider.
When a request is made for a video, the edge server checks the WMID token to ensure that it is authentic before responding to the request. The WMID that was provided in the token is used to apply a watermark to the ABR video that was requested, and this only happens if the compliance tests are successful. This happens if and only if all of the tests are passed with flying colours. After that, the content delivery network (CDN) will disseminate videos that have already been watermarked, ensuring that every customer will receive their very own, individualised video stream. This will be done by distributing the videos that have already been watermarked.
Utilizing edge computing for bitstream watermarking can reduce the requirements for storage and bandwidth while simultaneously raising the video latency. This is made possible by the fact that it is only necessary to watermark a single version of an item. This is due to the fact that there is only one version of an asset that requires a watermark to be applied. This is because there is no requirement for there to be more than one version of an asset that contains a watermark in order for it to be effective. If the watermark can be located and obtained in advance, it will be much simpler to identify leaks and repair any damage that may have been caused as a result of those leaks. If the watermark cannot be identified and retrieved in advance, it will not be possible to identify leaks.
