Lockervideo is one of the rare software making it possible to integrate a confidential code of reading into the video files residing or forwarding on its hard disk, whatever is extension (avi, mpg, MPEG, wmv) and whatever is type (divx, xvid, etc). This protection prohibits thus purely and simply the reading of all beforehand encodés documents vidéos if the personal password were not correctly seized; and this, whatever the multi-media reader used. It in addition leaves the free access to any other video document which was not thus treated.
