WHAT'S IN YOUR PROFILE? MAPPING FACEBOOK PROFILE DATA TO PERSONAL SECURITY QUESTIONS

This study investigates data privacy concerns regarding the use of Facebook and university students’ awareness of privacy control mechanisms, privacy best practices, and possible consequences of unprotected information-sharing in Facebook. Research found that students share a large quantity and variety of personal data in their Facebook profiles that, if compromised, could be used by an attacker to answer personal security questions setup as fallback authentication methods for other online accounts. The consequences of this type of data breach could include unauthorized bank account access, identity theft, or other crimes. Results suggest that students are generally unaware of best practices for data protection within Facebook, and often misuse available privacy control mechanisms. The researchers conclude by offering a set of best practices Facebook users can follow to help protect data privacy in Facebook.
