This functionality is accessible by default for hardware level DRM implementation from each of the three major DRMs (for example, Widevine Modular Level1, Playready SL3000, and Fairplay DRMs (with Operating System 12+)). Nevertheless, this security is largely applicable on native app implementation types on mobile devices; whereas, viewing the material through a browser on Android devices is not necessarily subject to the same limits.
For instance, if an Android device is able to support widevineLevel 1 implementation, then it offers security against screen recording while content is being played using an Android application. This protection is provided even if the device is not specifically designed to do so. The device provides this level of defence for its user.
The same gadget, however, cannot offer the same level of protection to the user when the content is being played on browsers as it does when the content is being played on mobile devices (like chrome). Because these browsers do not offer compatibility for the widevine DRMan anti-piracy technique, utilising Firefox or any of the other browsers is not an option when the content is being consumed on an Android smartphone. This is because widevine DRMan is an anti-piracy mechanism. If, on the other hand, the service provider has a compelling use case to provide chrome browser-based playback on android mobile and they would also like to ensure protection against screen capturing, then they will need to invest in chrome-specific screen capture protection solutions such as this anti screen capture solution. They also have the option of deciding not to offer playback via the Chrome browser on android-based mobile devices.
The protection of the output, which is also referred to as HDCP or CGMS:
After being enabled with the appropriate parameters, digital rights management solutions (DRM) are able to provide the capability to defend against recording using digital output signals (such as HDCP) or analogue output signals. This is possible for DRM to do (such as VGA, etc.).
Once this is activated, it ensures that the content that is being sent is of HD quality and that, once it has been copied out, it will not be reproduced using HDMI or VGA types of digital or analogue output. In addition, once it has been copied out, it prevents it from being reproduced using any other type of digital output. In addition, it stops any other kind of digital or analogue output from being used to copy the content, thus it can’t be copied. Devices that are able to activate the hardware level of DRM implementation are the only kind of devices that are able to make this feature available to users (e.g. Widevine Level 1 for android). It is not possible to make this feature accessible on devices that only have a software implementation (such as Widevine Level 3 on Android), which describes every other type of device.
However, despite the fact that some devices offer support for DRM at the hardware level, it is not as easy to accomplish as it might appear due to the complex nature of HDCP implementation on the device’s end. This is the case even though some devices do offer support for DRM. The following chain of events has a good chance of producing results that are difficult to anticipate.
During the process of encrypting the movie, the data in the video clip will be jumbled up by an algorithm, and as a result, the file will be useless once the encryption is complete. As a direct consequence of this, there is not even the remotest possibility that the data might be decoded. This is made possible with the use of a key, which, in conjunction with the algorithm, is used in order to encrypt and decode the digital information. This makes it possible for a third party to read the information that has been encrypted. Because of this, it is now feasible for an outside entity to view information that had previously been encrypted. As a result of this, it is now possible for an external party to view information that had been encrypted in the past. Despite the fact that the information has been encrypted, it is not going to be very difficult to interpret it due to the reason stated above. The audio, the video that was captured in standard definition (SD), as well as the video that was captured in high definition (HD), each make use of their very own one-of-a-kind special key. This applies to both the video and the asset (HD). The process of encrypting or decrypting a video clip is considered to be an operation that uses symmetric cryptography because of this reason. This is possible due to the fact that both the encryption and decryption processes use the same key. This is due to the fact that the same key is used for both the encrypting and the decrypting of the file when using symmetric cryptography.
