I Recognize That Face
You might think of fingerprint or retinal scanners when you hear the word biometrics, but the term has a broader definition. Facial recognition technology falls into the biometric category. There are already several cameras on the market that can detect faces. A few are able to recognize and remember a group of faces. You just take a picture of a friend, tag the photo and the camera will automatically tag any future photos of that friend. It's both cool and creepy.
Imagine using this technology in public places to identify the people passing through. For example, a major city might install cameras at high-traffic areas to scan for terrorists or identify criminals. While the motivation for using that technology might be pure, it creates difficult privacy issues. The city would have a record of everyone who passed through that neighborhood. The technology treats everyone as a suspect as if it's only a matter of time before each of us commits a crime.
And what happens if the technology makes a mistake and misidentifies someone? Weather conditions, clothing, hairstyles and even the cleanliness of the lens could affect the ability of the camera to identify people. Critics might ask: Why install a system that's unreliable?
What happens if a person suffers an illness or injury that changes his or her appearance? Such a change could present problems with biometrics. Adjusting the biometric system to accommodate the change could also result in a violation of the user's privacy. The system administrator now knows more details about the user.
A society with pervasive biometric systems would make anonymity a virtual impossibility. Should that society become oppressive or otherwise abusive to the population, the citizens would have few opportunities to react without revealing their own identities.
Groups like the Biometrics Institute are aware of privacy concerns and strive to create processes to limit the chance for biometric applications to violate a person's privacy. Other groups advocate that companies, governments and other organizations conduct a privacy assessment before installing a biometric system. With vigilance and caution, we may find a way to incorporate biometrics into our lives and still maintain our privacy.
