4.7 Authenticating Recorded Video
VIGIL Server embeds a security key in recorded footage for each video frame. These keys can be easily checked to verify that the
footage is authentic and has not been tampered with.
Begins the authentication process; a window opens displaying the progress. Depending on the length
and location of the video footage, authentication may take several minutes to complete. You can
cancel the authentication at any time by clicking Cancel. Any frames that were processed prior to
cancelling have been authenticated. If the video is authentic, the Authentication Complete mes-
sage will be displayed.
If the video has been tampered with, the authentication will halt at
the first damaged frame and provide an error message with the
problem frame number.
If Real-Time Authentication (in VIGIL Server Settings |
Search tab) is enabled, during playback a large red X is dis-
played over the frame if the footage does not pass authen-
tication.
