Understanding Digital Rights Management (DRM)

Have you ever wondered why you can't record or download videos from Netflix or other streaming platforms? This is due to a technology called Digital Rights Management (DRM), which prevents piracy and protects content creators' intellectual property.

How DRM Works

DRM is a way for companies like Netflix, Amazon Prime, and Hulu to protect their videos from being downloaded or recorded. When a video is played on a platform with DRM enabled, the video is encrypted and can only be decrypted by a trusted executable environment. This means that even if you try to screen record or download the video, you'll only get a scrambled or encrypted file that can't be played.

Encryption and Decryption

To understand how DRM works, let's take a step back and look at encryption and decryption. Encryption is the process of converting plaintext (readable data) into ciphertext (unreadable data). Decryption is the process of converting ciphertext back into plaintext.

In the case of DRM, the video file is encrypted using an algorithm like AES 128. To decrypt the file, you need two keys: an encryption key and an initialization vector (IV). Without these keys, the video file remains encrypted and can't be played.

Widevine and FairPlay

Widevine and FairPlay are two popular DRM solutions used by Google and Apple, respectively. These solutions provide a secure way to play protected content on devices like smartphones, tablets, and smart TVs.

How DRM is Implemented on FON

FON, a platform for creating and selling online courses, also offers DRM protection for its videos. If an instructor wants to protect their video content, FON can enable Widevine and FairPlay DRM, which ensures that the video is only playable through a trusted executable environment. This prevents piracy and ensures that the video content is protected.

Conclusion

DRM is a complex technology that protects digital content from piracy and unauthorized use. By understanding how DRM works, we can appreciate the efforts of content creators and platforms like Netflix and FON to protect their intellectual property.
