Encryption
Locking, Encryption and Decryption of Media Files can be performed in real time by VCube. This process is based
on MTAK technology. (Merging Technologies Active Key).
Active Key does two things:
1. Protects non-encrypted Media Files from un-authorized use. This enables Media Files created by VCube or
Pyramix to be locked out from Playback or Processing in a VCube or Pyramix Timeline by using a metadata
flag in the files themselves. This first level of security prevents media files from Playout but the actual data
streams in the files are not encrypted so they remain CPU efficient since they do not require real-time encod-
ing or decoding when they are created or played back.
2. Protects and encrypts media at the time of creation making un-authorized use of these files virtually impossi-
ble. 128bit data encryption of the actual media files themselves is applied in real time as well as a metadata
flag indicating to VCube and Pyramix that the files in question are protected from playback via Active Key and
must be authorized before they may be decoded in real-time for playback or further processing.
