Video Protection and Security

Encryption is the process of scrambling the video file, so that the video can only be played using the authorized content keys

DRM systems manage the content keys used to encrypt the video, and to provide a secure environment in which video is decrypted

Widevine DRM is Google's DRM licensing technology for streaming encrypted videos in Chrome, Android and Chromecast

Advanced Encryption Standard (AES-128) is the encryption algorithm used by DRM systems to encrypt videos
