In many ways, cell phones have become tracking devices. We all know that they can reveal a lot of information about you, such as your location, who you called, and when you called someone.

In this article, you’ll learn how even if you follow every Edward Snowden-prescribed privacy precaution, your phone can still give away your secrets.

A group of scientists at the University of California, San Diego has discovered that taking a simple cotton swab of a cell phone could reveal all such information, and it could have profound implications in areas from medical research to law enforcement.
