This article is about the technique developed my Pritam Gundecha of Arizona State University. The technique allows users to determine the friends they keep on social networks, such as Facebook. Pritam used statistics with the number of people who disclose information, like their home address and gender. She used this to give users a "vulnerability score", which can be altered by removing people as friends. Pritam says, that for every person you remove as a friend you get five percent of your security back. This article made me realize how much people learn about me just by what I post or what others post on my Facebook wall. I could have a friend check me in to the 5th Ave Mall and have someone from home back in Southeast call me up, and ask me to grab something for them. Not even joking, it happened to me just last week. I was at the mall with my roommate and some friends from up here. Within a few minutes of being checked into the mall one of my friends calls me and asks if I would pick up her and her brother a sweatshirt from Madhatter. It's amazing how fast your personal life travels on social networks, just by how many friends you have. If you aren't careful about who you add, you never know what might happen. Someone could steal your identity, or telling the whole world about what you did yesterday or where you are today.
