Not only in Vietnam, but around the world, media units always have to worry about copyright protection. Watching and downloading pirated movies from these platforms is not an easy task for any basic user. The reason for this barrier comes from Widevine. So what is Widevine Leak? What is Widevine L1? In this detailed article, Thu Do Multimedia will introduce to you one of the ways that platforms protect digital right management on the internet!
Widevine DRM – Something that prevents you from taking screenshots
Taking a screenshot seems like a harmless action. But if we can take screenshots, why can’t we record the entire movie screen and then share it on pirated movie sites?
That’s what media units are afraid of, and to completely solve the problem, they won’t let you take screenshots while using them.
In fact, preventing you from taking or recording your screen is not simply a small feature of the application, but behind it is Widevine, one of the security certificates to protect content on digital platforms.
Widevine is a type of security certificate to protect digital content that Google has developed and integrated on its devices since 2010. Simply put, Widevine will prevent digital content (on Netflix or similar platforms). similar) may be downloaded or copied illegally.
Widevine certification helps your device meet security requirements, allowing you to have the best user experience. But even when equipped with Widevine, each device has a different level of Widevine.
If your device is equipped with Widevine L1, the highest level, you will have Netflix streaming on your phone at the highest resolution (4K, Full HD). On the contrary, if the device only has Widevine L3, you can only stream content in basic image quality (SD 580p).
What is Widevine level protection?
Widevine comes in two versions: Widevine Classic and Widevine Modular. The first version, Widevine Classic, supported devices from 2017 and earlier and has now been discontinued by Google. The version that is trending and will also be mentioned in this article is Widevine Modular.
Widevine certification will affect two processes: Video decoding and processing. Both of these processes must be executed in the TEE (Trusted Execution Environment), a partition on the terminal motherboard that handles confidential data. This helps ensure that the data that needs to be protected (in this case copyrighted movies and TV shows) is not violated, filmed, captured, and shared illegally with third parties.
Widevine certificates do not charge copyright fees, so manufacturers will not have to pay additional fees to integrate them into their devices. Widevine comes in three levels: Widevine L3, Widevine L2 and Widevine L1.
What is Widevine L3?
Widevine L3 is the lowest security certificate. These devices will not process video through the TEE. Therefore, streaming content will be easily interfered with by third-party applications. Due to such a great risk, devices that own Widevine L3 will only stream content at the highest level of SD 580p.
What is Widevine L2?
Sitting in the middle is the Widevine L2. This level of security is often jokingly called “amphibian”, since only video decoding is performed at the TEE. The remaining video processing will be performed outside the TEE partition. This will still create loopholes for third-party applications to interfere with content that needs to be encrypted. Therefore, devices that support Widevine L2 can only stream content with a resolution of 720p or lower.
About 10 years ago, 720p was an ideal number for HD video. But since mid-2020, major video sharing platforms like YouTube have downgraded 720p to SD. In addition to recent devices improving image quality, streaming content above 720p is no longer as popular as it was in the past.
What is Widevine L1?
Winevine L1 is the highest level of security. Most smartphones today are equipped with this level of security, so it has gradually become a common standard for phone companies to integrate this certificate into their products.
At the L1 level, all video decoding and processing will be performed entirely in the TEE partition. Therefore, third party intervention will be almost impossible. Copying and sharing encrypted data (such as Netflix content) on these devices will be impossible.
Devices equipped with Widevine L1 can stream the highest quality video from today’s streaming platforms because copyright concerns are minimized.
Widevine on Smart TV
Most smart TVs on the market today are equipped with Widevine. TVs from 2017 and earlier will be equipped with Widevine Classic.
However, cheap smart TVs or domestic products in the Chinese market will often not have Widevine L1 but only Widevine L3. Because they do not meet the L1 standard, these TVs, even running Android, will not be able to be installed from the app store. Installing APK files from outside is also not the optimal solution.
Widevine on Android TV Box
Android TV Box is an external device that “turns” your TV into a Smart TV. The Android TV box market has really exploded recently due to users’ need to enjoy digital content. And of course, Android TV Box must also have Widevine certification to bring the best experience to users.
Cheap Android TV Box products are usually only installed with Android for mobile devices, with Widevine L3 certification. This not only causes inconvenience to users but also leaves open the possibility of users being upgraded and supported in the future. In contrast, reputable Android TV Box products will have Android TV installed, a specialized version for TV Box devices, and comes with Widevine L1. Users should carefully study the device’s information before purchasing.
Sigma Multi-DRM Against Widevine-leaked
Recently, some accounts have shared ways to “Dump Widevine” through which hackers understand the structure of Widevine and find ways to bypass the License Server to get the decryption key.
There are many efforts to combat copyright infringement, like the MPA asking internet organizations such as Github to remove accounts that promote copyright infringement; and as most copyright protection organizations, Sigma Multi-DRM and Thudo Multimedia also finds ways to prevent the exploitation of Widevine vulnerabilities by hackers.
In Vietnam, thanks to the special design through the “Sigma Active Observer” – SAO- protection layer, Sigma Multi-DRM not only provides a solution to protect content with key encryption, but SAO also helps observe all Abnormalities in the process of exchanging rights between License Server and Devices. Success from observing to warn, as well as eliminating abnormalities has helped many large content providers such as TV360 (Viettel) or FPT Play (FPT) stand against Widevine leak exploitation.
