Scientists have learned to identify the authors of anonymous videos

The next time you put on a GoPro or other wearable camera, remember that all your moves can be read as easily as a fingerprint. A new study found that owners of wearable video cameras leave biometric traces by which they can identify in a few seconds.
According to The Verge, scientists at the Hebrew University in Jerusalem have developed an algorithm that allows to identify the author of video camera shake. Shake the camera during shooting, are a kind of biometric signature inherent to a specific person.
To identify a person by one video is almost impossible, but you can reach him through a series of other videos with the same signature.
Four million four hundred six thousand seventy six
Researchers see this method of authentication is bad and good side. For example, a device like Google Glass could make use of the nature of the movements of the camera to authenticate a user who requests access to personal information. On the other hand, the biometric signature may fall into the hands of hackers who can later use it for their own selfish purposes. It is also possible that in this way law enforcement can expose criminals or to catch the protesters.
As the authors of the video provide enough information about yourself, experts advise them to exercise more caution when exchanging raw content. But researchers note that the stabilization of 2D video during shooting is not particularly affect the result, but a more complex system for image stabilization more difficult to identify the signature. Given the constant desire of manufacturers to produce cameras with maximum protection from shock, over time, this issue can be addressed by itself.
