If you forget your password when logging into an e-mail or online shopping Web site, the site will likely ask you a security question: What is your mother’s maiden name? Where were you born?

And if they don’t, it might not be hard to search for it online or even make a lucky guess. But Rutgers computer scientists are testing a new tactic that could be both easier and more secure.
