Abstract: A system and method for recording, backing up, and authenticating footage from a dash cam or other video device comprises continuously synchronizing checksums from segments of video as they are recorded into rolling storage with an authentication server located remotely. Only metadata is uploaded until the video device experiences an interrupt event, at which point the last few rolling segments, as well as subsequent rolling segments until the termination of the interrupt event, are written to persistent storage and uploaded to the authentication server at the earliest opportunity. The metadata and video are encrypted with an asymmetric public/private key system enabling third parties to confirm, with the public key, that the metadata on the recording device and the authentication server match, and with the private key, download the video footage from the interrupt event.
