First-person camera could reveal your identity.

Do not show, do not show body, GoPro, Google glass, such as the first-wear equipment photographed only what I see is the world, so you think uploading such a video is anonymous? Maybe it's silly and naïve to think that way. Professor Shmuel Peleg of the Hebrew University of Jerusalem and Professor Yedid Hoshen published a paper called egocentric video biometrics, which says they have discovered a new method of identification: Based only on the jitter of the camera.

In an interview with The Verge, Professor Peleg said that each person's body size, height, muscle, and bone are unique, which determines that each person's physical movement is also very different. So, in theory, the identity of the video producer can be identified based on the analysis of the body's movements. Also, the video length requirement is only 4 seconds.

Professor Peleg says the video taken by a headset is like a fingerprint of a person. We can find a person by using a fingerprint sample, and by comparing the video we can determine if the video is recorded by the same person. He also said the results were published to remind people to think twice before uploading the video, and that not having a little face doesn't mean you're hiding. (So, human beings, do not preach, or do not shake.) ）

At present, two professors of the research object is limited to the video of the head-wearing equipment. Next, the scope of the study may extend to surveillance video. After all, we can see some of the characteristics of body movement from the monitoring. Using this method to achieve identity is "possible," says Prof Peleg, especially in countries like the UK where surveillance cameras are rampant. It is reported that in the UK, every 11 people have a surveillance camera.

In addition, since it is possible to identify identities through a headset, Professor Peleg and Hoshen are also quite confident that the method should be applied to video recordings made by wearable cameras. As a result, Mr Obama's moves in the previous days have been underpinned by a theory. December 1, Obama to Congress for 3 years, a total of 263 million U.S. dollars in the appropriation plan. Of these, 75 million will be used to purchase 50,000 wearable camera equipment for use by state and local police.
