As the costs of the technologies fall, biometric identification tools — such as fingerprint, iris or voice-recognition scanners — are increasingly being used in everyday life. There are significant privacy questions that arise as biometric data is collected and used, sometimes without the knowledge or consent of the individuals being scanned.
Biometrics use has become more commonplace. Many smartphones, including iPhones, have fingerprint “touch” ID scanners that people can use instead of numeric passcodes. And law enforcement personnel have been using fingerprint scanners for years, both domestically and internationally. In the past few years, we’ve see banks capturing customers’ voice prints in order, the institutions say, to fight fraud. Or gyms asking members to identify themselves using their fingerprints. Reuters recently reported that companies are seeking to expand fingerprint-identification systems to credit cards and railway commuters.
And the voluntariness of a person submitting his or her biometric has also been questioned. Do you realize when you’re calling your bank that you’re handing over your voice print? Another situation a few years ago in Washington, D.C., also raised at the issue of voluntariness. The District considered requiring that all visitors to its jail “have their fingerprints scanned and checked against law enforcement databases for outstanding warrants.” So if you wanted to visit a friend or relative who was in the D.C. jail, you would have to volunteer to submit your biometric data. The plan was dropped after strong criticism from the public and civil rights groups.
Your biometric data can be gathered for any number of innocuous reasons. For example, I had to submit my fingerprints to obtain my law license, not because of a crime. Family members, roommates and business colleagues of crime victims have submitted fingerprints in order to rule out “innocent” fingerprints at a crime scene in a home or workplace. Some “trusted traveler” airport programs gather iris scans. Some companies use iris-recognition technology for their security systems. Read more »
