I think its going to be less possible in the future. Computers are causing us to lose privacy, and that's only going to continue. That's both though social media, which we can control (so far), and government records, which we can't.
Social media is working towards identifying people even when they don't opt-in, and that's really bad. Fortunately society is becoming more accepting, but also still not actually accepting, and it may also go the other way in the future. I don't see the trend to losing privacy reversing though.
