With a Particular Emphasis on How Effective It Is in Preventing the Piracy of High Definition and Ultra High Definition Video
The great majority of people today view movies using over-the-top (OTT) platforms like Netflix and Amazon Prime rather than downloading video files and saving them on their own personal electronic devices to watch later.
The simplicity with which viewers can access the same videos across a range of platforms offers a variety of challenges for the owners and producers of content. Piracy and the limitation of the number of concurrent streams that may be seen with a single subscription plan are two of the problems that need to be addressed.
In addition, the industry faces a significant challenge in the form of a problem when it comes to the delivery of high-definition (HD) content to the device of a user while at the same time ensuring proper hardware and software security in order to prevent leaks. This presents a significant barrier for the industry to overcome.
One approach that can be taken to address these issues is the implementation of digital rights management (DRM), which is also commonly referred to as anti-piracy software.
Widevine by Google is a well-known digital rights management (DRM) solution for high-definition (HD) video that was developed by Google. It is compatible with the web browsers Chrome and Firefox, as well as mobile devices running Android OS and smart TVs. Widevine by Google was named after the company that developed it.
Widevine is the primary content security solution employed by the vast majority of well-known over-the-top (OTT) players and video streaming services.
Widevine provides protection for video streams on not one but three distinct levels, namely the hardware, the software, and the code.
The protection that is provided by digital rights management (DRM) relies heavily on CENC, which is an acronym that stands for common encryption protection scheme. In order for a digital rights management content decryption module (CDM) to be able to decrypt video files on a client device, it is necessary for this document to define the encryption standards and key mapping methods that are used by the CDM.
Widevine makes use of CENC protocols to link individual video files to the licencing keys that are distributed to content packagers. This is done so that adaptive bitrate video playback can be facilitated on client devices.
Adaptive streaming is an absolute requirement for content creators because of the potential revenue loss that could result from allowing access to HD content on insecure devices. Due to the fact that adaptive streaming is an absolute necessity, content creators are required to use it. Adaptive streaming is an absolute necessity.
According to Widevine’s definition of security levels L1, L2, and L3, the level L1 offers the highest level of protection when it comes to watching premium HD films from OTT giants.
When it comes to transmitting videos of a high quality, Widevine is reliant on the trusted execution environment (TEE) of the processor in the device.
The TEE is able to make the most of the capabilities of both the central processing unit (CPU) and the memory because it is run in a manner that is completely separate from the processes that are responsible for the operation of the operating system. As a consequence of this, the procedure is one that is not only more secure but also less likely to be compromised by an attack.
Because the encryption keys for TEE apps are hard-coded into the chips that make up the processor, it is very difficult to make any changes to these applications.
Utilizing the TEE to generate a zone that is unique in comparison to the other zones for the purpose of carrying out the execution of Widevine’s code is the method by which one can achieve L1 security.
The TEE is accountable for the simultaneous processing of video as well as encryption at all times.
Traditional “single DRM” systems required the installation of an independent browser plug-in, such as “Flash,” in order to secure audio and video content that could be played in a web browser. This was necessary in order to prevent unauthorised access to the protected media files. In order to prevent unauthorised access to the content, this was an absolutely necessary precaution to take. This needed to be done in order to prevent unauthorised use of the content, which is what made it an absolute necessity to be completed. On the other hand, the support for plug-ins in web browsers is gradually being phased out due to a variety of performance and security concerns. This is happening for a number of different reasons. As a consequence of this, digital rights management (DRM) solutions that are reliant on plug-ins are losing their place in the market and will eventually be completely phased out.
