An in-depth investigation at Google’s Widevine digital rights management system.

Specifically focusing on how it prohibits users from copying high definition and ultra high definition movies. Over-the-top (OTT) platforms, such as Netflix and Amazon Prime, are where the great majority of consumers currently watch videos, as opposed to storing video files on their own personal devices.

Because users can watch the same videos on a range of devices, content owners and creators face a number of issues as a result. Piracy and the fact that a single subscription plan places a cap on the number of streams that can be played simultaneously are two examples of these problems.

In addition, the business world faces a huge challenge when it comes to the delivery of high-definition (HD) content to the device of a user while at the same time making certain that both the hardware and the software have enough levels of security to prevent data leaks.

One approach to resolving these challenges is through the utilisation of digital rights management (DRM), which is also referred to as anĀ anti-piracy technology.

Widevine by Google, which was developed by Google, is a well-known digital rights management (DRM) solution for high-definition (HD) material. It is compatible with the online browsers Chrome and Firefox, as well as mobile devices that run the Android operating system and smart TVs.

In order to guarantee the safety of their content, the vast majority of well-known OTT players and video streaming services make use of this.

This technique safeguards video streams by employing software, hardware, and programming code.

The “common encryption protection mechanism,” which is referred to by its acronym CENC, lies at the centre of the protection provided by digital rights management. It supplies the encryption standards and key mapping procedures that a DRM content decryption module (CDM) employs to decrypt video files on the client device. Video files can be decrypted using these several methods.

CENC protocols are supplied to content packagers in order to enable client devices to view movies at variable bit rates. Widevine makes use of these protocols when it comes to tying video files to licencing keys.

Due to the fact that it enables people, adaptive streaming is an absolute necessity for content providers. If people watch HD content on devices that do not offer sufficient protection, there is a chance that they will suffer a loss of financial resources.

The L1 security level offers the maximum level of protection while playing premium HD videos from major OTT services, in accordance with Widevine’s definition of the L1, L2, and L3 security levels.

The trusted execution environment (TEE) of the device’s processor allows for the transmission of video of a high quality over the Widevine protocol.

The Trusted Execution Environment (TEE) is the entity responsible for safeguarding the code and data in a secure part of the processor. This strengthens its security and decreases the risk that it will be hacked in the future. It is able to make the most of the power that the CPU and memory have to offer because it is not dependent on the operating system in any way.

Applications utilising TEE also require the use of hardware. It is incredibly impossible to change the encryption keys because they are hard-coded into the processor chip of the computer.

In order to generate Widevine’s code an environment that is unique to itself, the TEE is utilised as part of the process. This ensures that security at the L1 level is maintained.

The TEE is accountable for operating on both the video and the encryption at the same time.

The capability of a web browser to play digitally protected information without the need for a separate player to be installed on the computer. Plug-in is one of the benefits that users of multi-DRM systems receive from the use of these systems. You can make DRM content playable on the overwhelming majority of diverse operating systems by utilising only one web application. eliminating the requirement to design “native” programmes for each client platform, such as personal computers and mobile devices, is just one of the many advantages.
