"The great advantage of voice is that all computers and phones have the sensor built in, whereas other biometrics require additional sensors," says Mike Brookes, a signal-processing researcher at the Imperial College of Science, Technology, and Medicine in London, who specializes in voice recognition. And, he adds, voice recognition also allows you to keep your hands free.
"Voice has been on the verge of breaking through for a number of years," says Brookes. He believes voice verification technology will finally start to take off, particularly with telecommunication and cell-phone companies, who are keen to push e-commerce services via Internet-enabled cell phones.
Another reason for the adoption of voiceprinting is the recent introduction of so-called "smart" credit and debit cards. These cards have eliminated the use of handwritten signatures for authenticating payments, and instead require customers to punch in a four-digit PIN, which is then verified against a number stored on a chip on the card.
Since the recent mass introduction of these PIN-verified cards in the U.K., for example, most types of credit-card fraud have plummeted. According to figures released in February by the U.K.'s Association for Payment Clearing Services (APACS), credit-card fraud dropped by 13 percent in 2005.
But one type of fraud continued to rise last year, by 21 percent: the problem lies in transactions made over the Internet, by phone, or by mail order. In these kinds of transactions, a card's information can be read out or typed in without additional authentication. The field of biometrics, in general, and voiceprinting, in particular, could go a long way toward solving this problem, Harris says.

Now the only technology required to steal your account is a wire-tap or voice-recorder. Duh.
Guest (Jason)
So that explains why they are wiretapping us
They say it is just international calls but it is all calls.

Using recordings for impostering
If one uses text independent SIV with a liveness test, you go a long way to preventing successful imposter attacks. Of course, nothing is perfect or 100% accurate. Not even humans.

How much would it cost an organization to implement a system like this one?
Guest (Leprechaun)
Cost depends on whether you are first
Roughly, the first org will pay $100 million. The second will pay $100 thousand. The twentieth will pay $10,000 per processor, in license fees.

does this mean i can't log in if i have a sore throat or if i catch cold?

It is well known that private investigator have voice simulation software/hardware. They use it to similate an acquaintance/friend and call up people and ask questions. Thus tricking the person to review vital information to someone they thought is a friend over the phone. They can use the same technology to access your account by tricking your computer to think it is you over the phone.
Guest (Dan Miller)
It's incorrect to say that voice simulation software can spoof a voice biometric... It's not a recording of the voice being saved. It is unique aspects of the voice in a profile. Tape recordings of the actual voice and voice simulation are not effective.
Guest (Leprechaun)
You just get a copy of the biometric hardware and tweek your simulation until it passes. No problem.

haha... i guess nothing is really "secure"
haha.. maybe nothing is really "secure." i don't know what's in hold for the future.

If memory recalls, there is a 2004 report published at a biometrics conference at Oxford that shows that normal sore throats, sinusitis and aging doesn't dramatically impact a speaker verification system's effectiveness. Of course, major illness, such as complete laryngitis, can reduce proper authentication. The general rule is that if your mother can recognize your voice, so can the automated speaker verification systems.

In the case of a person having a cold, there is a increase in false rejects but not in false accepts. It is therefor a human factors issue not a security issue
Manufacturing in the United States is in trouble. That's bad news not just for the country's economy but for the future of innovation.

Accuracy?
This sounds great. Any statistics on its accuracy?
