A Russian photographer has used facial recognition and image searches to look at privacy implications of the technology.Using an app called Find Face, Egor Tsevtkov used random images of people that he took walking through underground stations. He then searched through Russian Facebook rival VKontakte.Through Find Face, Tsevtkov found the profile pages of at least 24 people. With their profiles he was able to understand personal details about their lives, including their hobbies, professions, relationship status and eating habits.”I was feeling creepy, because when you learn a lot about somebody's private information like family, or work, or pets you see them in another way,” he said, reported The Telegraph.”This experiment highlights the disconnect between individuals believing they are sharing personal information and pictures only with friends, family, and colleagues, when in reality such information is virtually public,” said Christopher Weatherhead, a technologist for Privacy International, told the newspaper. “It is critical that we should retain control of the information we put online.”
