Technology has opened the world up. We can find information and photos on just about every subject you can imagine. And as we become more and more absorbed with the world of social media, the more we forget and ignore just how much of ourselves we are exposing. Putting our profiles in private settings is a false sense of security and anonymity, assuming only family and friends can see what we are up to. Russian photographer Egor Tsvetkov has taken photos of approximately 100 strangers going about their day in St. Petersburg. His project *Your Face is Big Data* is both a troublesome and impressive example of the power of technology.
