While the media face is hidden, fixed on the head or the body of the camera will give all the information to identify it. Scientists argue that it needs only 4 seconds of video from the camera, which should be compared with already in the database rollers - as is the case with fingerprints.
To determine the owner, used biometric characteristics such as height, stride length, walking speed.
Egocentric Video Biometrics - so called
published study . Now common camera GoPro, manufacturers are trying to sell a variety of smart glasses. Anonymous users using these cameras are now under threat: study suggests the possibility of identifying it with the comparison with other base video. But there is a positive side too - for example, cameras, equipped with a system using such technology can not be used by thieves, they just shut off automatically. In social video service can be set up automatic detection of the user who has removed the video.
For precision work technology the camera should be mounted on the human body, so shooting video with a conventional camera will not help identification. The minimum duration of the video should be 4 seconds. One of the authors compare the fingerprint technology: for her, too, need a database for comparison. The more "smoothly" to make a video, the more movement on it - the higher the possibility of identification. In this case, even the use of software stabilization reduce the quality of only 2 percent.
