Abstract

Method for producing a video stream (PR), comprising a) authenticating a first user (122,122''); b) capturing a first primary video stream (PV) showing the first user (122,122''), comprising a first primary authentication video part (AP); c) capturing a fourth primary video stream (PV) visually showing the first user (122,122'') from a different point of view, comprising a fourth primary authentication video part (AP); d) calculating one-way functions (OW) of the first and fourth primary video streams (PV), each being calculated using the respective primary authentication video part (AP); and e) automatically producing the produced video stream (PR) based on the first primary video stream (PV). For each of the one-way function (OW) outputs, the output is embedded into a least one of the video streams so that the embedding de- pends on content in a video stream which is not the same as the video stream into which the embedding is made; the output is stored; and / or the output is publicly published (PP).
