Biometrics: Using Physical and Behavioral Characteristics to Combat Identity Theft
Every day we read about the theft of personal data from organizations we thought would be able to protect this
information. If we can’t count on organizations like banks, credit card companies, hospitals, and the government’s Office of Personnel Management to protect this information, how do we interact in a world where we must verify that we are who we say we are?
Biometrics, the physical or behavioral characteristics unique to you, offer a viable solution to this issue. Physical characteristics such as fingerprints, face, iris, hand geometry, speech, and DNA, as well as behavioral characteristics like your gait, keystroke patterns, and heart beat rhythm hold the key to protecting your identity and personal information.
For this edition of The Download, we will compare a number of biometric signals to understand those most useful in preventing identity theft. We will also review the maturity of equipment, including smart phones used to collect biometrics; discuss the vulnerabilities of biometric identity systems; and look at current examples of biometrics used by the military in Iraq and Afghanistan for identity recognition.
