Woman Finds Identity Stolen On Facebook
Experts Say Fake Profiles Easy to Make
UPDATED: 8:55 am CST February 4, 2009
MADISON, Wis. -- Privacy experts are reminding people who use online social networking sites like Facebook to be careful not to fall victim to identity thieves. An area woman recently found out that it doesn't take much to create a fake profile page on a site like Facebook.
Gabriela Cezar, an acclaimed stem cell researcher, created a Facebook account about a year ago to network. But a search for the University of Wisconsin researcher today turns up two Gabriela Cezars. She said that about a month ago someone stole her name and picture and is posing as her.
"On a more personal level, it's very uncomfortable for us to imagine people being able to access your information under a fake profile that you don't even know," Cezar said.
Mike Masino, a security instructor at Madison Area Technical College, said that
listing simple data like your birth date, phone number or, in worst cases, your address, is dangerous and can give imposters enough information to harm your credit.
"If you do online banking, there's often a dropdown menu if you lose your password for information. There's a key word or something, usually it's a pets name or what school you went to or who's your best friend, (and) most people have all that information on their Facebook site and it's given out freely," Masino said.
Cezar said she is writing a complaint to Facebook, which has a section for fake page complaints on its Web site.
Experts said people who want to protect their identities on sites like Facebook or MySpace.com should limit the information they share on their profiles.Experts recommend managing privacy settings to block people from looking at your profile if they aren't on your friends list. Experts said people should only accept friend requests from people they actually know, adding that sometimes it's best to call the person and make sure they are the person on Facebook or MySpace.com.
