      Protecting your identity on Facebook

      Local assistant professor Rey Anzaldua knows a thing or two when it comes to computers and the World Wide Web.

      "I was there when the hackers were first getting started", said Anzaldua. "I'm still here where I've seen organized crime take over the hackers."

      Anzaldua's specialty is computer security.

      He's also written several books in computer forensics.

      This computer expert says you have to be careful about what you put on the internet. "Once you put something on the internet it is there forever.", said Anzaldua. "You post a picture, it's there forever. You put your public information or private information on the internet, it's there forever."

      Then you have social sites like Facebook that many people flock to.

      Anzaldua says, "On Facebook I've seen people put their name, siblings names, their children, spouse, address, phone number and e-mail address.

      They put everything in there but their checking account, and that just gives somebody who wants to steal their identity all the information they need." Action 4 News has learned teenagers and young adults seem to put more of their personal information out on the internet.

      "Stealing the identity from children is now becoming a really big business. A business that doesn't have to exist if your child's personal information is protected."

      Meanwhile your private information on Facebook may not me so private after all.

      According to the Wall Street Journal, many of the site's most popular apps are leaking users' personal information to dozens of advertising and tracking companies, no matter how you set up your privacy controls.

      The social networking site says it is taking steps to "dramatically limit" users' exposure.
