A Look at Google’s Widevine Digital Rights Management System

Google's Widevine

How It Stops HD and Ultra HD Video Piracy

Google’s Widevine Over-the-top (OTT) platforms such as Netflix and Amazon Prime are currently where the majority of people watch videos. In the past, consumers had to keep video files on their own devices in order to watch films. As a result of the ease with which users can access the same videos on multiple devices, content producers and owners are faced with a number of challenges, some of which include piracy and the restriction of concurrent streams on a single subscription plan.

Both of these challenges are a direct result of the ease with which users can access the same videos. In addition, one of the most significant difficulties facing the industry right now is providing high-definition information to a user’s device while simultaneously ensuring that the device possesses enough levels of both hardware and software security to prevent data loss.

These issues can be resolved by implementing a digital rights management (DRM) solution. Widevine is a well-known digital rights management (DRM) and anti-piracy solution that was developed by  Google’s Widevine. It is compatible with the Firefox and Chrome web browsers, as well as mobile devices running Android OS and smart TVs. The vast majority of well-known OTT players and video-streaming services depend on Widevine to protect the content that they provide to their users.

Widevine protects video streams on three levels:

The hardware level, the software level, and the code level. CENC, which stands for common encryption protection system, is at the core of this DRM protection. It details the encryption standards and key mapping procedures that a DRM content decryption module (CDM) employs in order to decrypt video files on the client device.

Widevine makes use of CENC protocols to link video files to the licencing keys that it distributes to content packagers like PallyCon’s in order to make it possible for client devices to be able to play back adaptive bitrate video. Adaptive streaming is an absolute requirement for content producers because of the possible income loss that could follow from enabling access to HD material on devices that do not have adequate security.

According to Widevine’s

Definition of security levels L1, L2, and L3, the L1 level provides the highest level of protection while playing premium HD videos from major OTT providers. Widevine is dependent on the trusted execution environment (TEE) of the device’s CPU in order to transmit high-quality video content.

The TEE is a process that is considered to be more secure and less vulnerable to hacking. Than other processes because it is executed independently of the processes that make up. The operating system and can make use of the full potential of the processor and memory. Code and data are protected within a safe zone in the processor with the help of the TEE.

TEE applications are similarly dependent on the hardware. And their encryption keys are embedded in the processor chip, which makes tampering extremely difficult. Obtaining L1 level security is accomplished by utilising the. TEE to set up a distinct zone for the execution of Widevine’s code. Within the TEE, both the video and the encryption are processed at the same time.

Multi-DRM systems have a number of benefits, one of which is the capacity to play. DRM material within a web browser without the requirement of a separate plug-in. You can eliminate the need to develop native programmes for each client platform, such as personal computers and mobile devices. By enabling the playing of DRM content on the majority of platforms with a single web application. This enables you to enable the playing of DRM content on the majority of platforms.
