A digital signature is cryptographic metadata that protects video from tampering. The Archiver or Auxiliary Archiver adds the digital signature to video frames.

Why use digital signatures?

Digital signatures protect your video against tampering and prove that it was not altered or manipulated, such as adding, deleting, or modifying frames. If video is altered, the digital signature will not match the original.

How are digital signatures applied?

Create fingerprint
Using a cryptographic key, a digital fingerprint is created based on the video frames.
Export the digitally signed video file
The exported video file contains the video frames, the digital fingerprint, and a copy of the cryptographic key. The file is now digitally signed.
