For a long time fingerprints have been  the ubiquitous identifier. They allow us to solve crimes, track people, and as of recently, even unlock our iPhones. But what if there was something even more dependable than fingerprints? New developments in technology indicate that that’s the case — we’re now seeing the development of voiceprints.

Voiceprints — more scientifically known as voice biometrics — are as distinctive as fingerprints. Companies have begun taking advantage of voiceprints to provide an extra layer of security for their customers — after all, it’s possible to get someone’s password, but you can’t duplicate someone’s voice. Basically, there are two ways that voiceprints can be used — either you have a particular phrase that you say, like a password, or you give a long sample of your speech involving many different sounds, and then the computer program can recognize you. There are many different possible combinations for how this technology can be used.

John Buhl of Vanguard, a company that has really started making moves on voiceprint technology, stated:

We’ve done a lot of testing, and looked at siblings, even twins. Even people with colds, like I have today, we looked at that.

In addition to using voiceprints as possible password protection, banks and other companies that deal with secure information are taking voiceprints to help weed out fraud. They’re hoping to prevent criminals from making false calls authorizing payments.

Finally, law enforcement officials are also using voiceprints and other biometric data. In the United States, the police are able to use voiceprints to track people who are on parole. In other countries, the use of voiceprints has gotten even more extensive. The New Zealand government alone has amassed over one million voiceprints at this point.

This is yet another intersection of technology and privacy that is both fascinating and concerning. The databases that both private companies and the government are currently compiling of people’s voices are not regulated, and they’re growing fast. The Associated Press estimates that roughly 65 million voiceprints are being stored in some combination of private and government databases.

There are a lot of privacy concerns inherent in this issue. One is that it could rob people of anonymity in cases where they so desperately need it, such as anonymous tips or counseling services. People may be pushed away from calling say, a suicide hotline, because they are worried that their voice would be tracked back to them.

There’s also a concern over the fact that in general, corporations and governments are collecting way too much information on us. A privacy expert at the University of Pennsylvania, Professor Joseph Turow, stated:

Companies are using data drawn from our internet and purchasing [behavior] – and now our voices – and connecting it to the identities that they’ve created for us. Then they can lead us in a variety of different directions, based on their stereotype of us.

Because we often see technology progress more quickly than our laws governing it, the use and collection of voiceprints are essentially unsupervised. That right there is an important lesson to keep in mind — we have this great technology, but at some point we may need to question the uses for it. While I don’t think that voiceprints are going away anytime soon, activists’ concern may slow the progression of collection until we figure out exactly how we want to use this new resource.
