A system for secured capturing and authenticating of video clips may include: one or a plurality of capturing devices, each of the capturing devices comprising a camera and a first processor, and configured to: acquire a time stamp; capture a video clip of a scene and attach to the captured video clip metadata that includes the time stamp; transmit a notification that the capturing of the video clip has ended; upload the captured video clip with the attached metadata to a remote service unit. The system may also include a remote service unit comprising a second processor and storage device, configured to: receive the notification; receive an uploaded video clip; authenticate the received video clip by: verifying that the received video clip is unedited with respect to the captured video clip; and verifying that a time stamp in a metadata attached to the received video clip is identical to the acquired time stamp and that a time interval between the time indicated by the attached time stamp and a time at which the notification was received is equal to a length of the video clip and a limited time margin. |
