Abstract
Provided is a video playback system based on approval of a playback approver. A decryption key that can decrypt an encrypted and stored recorded video is generated only when video playback is approved by a playback approver using an appointed playback approval method and transmitted to the video recording device so that it is possible to prevent leakage of the recorded video with sensitive personal information.
