Some banks are now moving toward a two-channel authentication approach similar to Voice Pay's, in which both the Internet and another channel such as a phone line are used to authenticate account holders, says Ross Anderson, a professor of security engineering at Cambridge University, in the United Kingdom. But while this added layer of security is to be welcomed, voice prints have yet to prove themselves.
"Experiments with many previous systems over the past 20 years have shown that voice prints just aren't good enough for unattended operational use in this kind of application," Anderson says. "Either you set the threshold so that everyone's accepted--fraudsters too--or you get too many false negatives."
Voice Pay claims to be different. Unlike older approaches to voice verification, which analyze the waveforms of a person's voice by breaking it up into its constituent fundamental frequencies, Voice Pay's system uses vocal samples to create a model of the person's throat. Dutch bank ABN-AMRO is currently installing the same underlying technology for its four million customers, says Harris.
Voice Pay won't reveal the false-acceptance and false-rejection rates for its system, however. It argues that consumer confidence will come from the fact that Voice Pay will guarantee all payments.
"You will always get false matches," says Harris. But the accuracy of the engine at this stage makes them so improbable that the system is more secure than existing payment systems, he says.
In fact, fraud should be dramatically reduced, says Ogden, because there's no need to dish out credit-card details during a transaction.
Since the system was quietly launched a month ago, more than 120,000 users have registered for accounts, says Ogden. But they won't be able to use their accounts until retailers come onboard and start including the Voice Pay icon within their shopping baskets.
Despite a global recession, mobile-payment services are surging in the developing world.
Industry leaders hope that new technologies will make mobile search more usable.
Another useful technology but...
... it is still going to need to integrate with systems that know what they are doing. Far too many of the systems banks and others use today are too dumb for this to help much. Only if the system can be updated to make sensible decisions will it be useful to add this. Then, however, it will be really useful

Will it understand us as other VRSs do?
If we want to make a payment will it say "I could not understand you, did you say 'Spray the Pan'?" Voice Recognition Systems today still require a massive amount of learning before you can use it without too many errors, but that's because the algorithms don't process the voices as humans do. First, it should determine if it could understand what was said without processing, then if it couldn't understand it should make a tree of most likely matches and filter the ones that don't make sense in context, then if it still can't figure it out with a high enough probability it should ask you to repeat louder or quieter or more clearly.
If someone designs a system using these steps can I get some money for the idea?
I do not trust this type of system for a couple of reasons. Right now the creator claims this system is reliable and that it will guarantee payments. I assume by guarantee that it will ensure a person making a payment is authenticated 100% of the time, which today's biometric systems do have some error rates. I predict there will be a technology race, if you will, between voice authentication systems guaranteeing a 100% authentication rate and voice synthesizing machines. I predict voice synthesizing machines will take a sample voice and be able to recreate every nuance in that person's voice, using similar algorithms as those used in the authentication scheme of this pay system (Voice Vault's 117 unique patterns), and effectively authenticate to this system.
Second, this system has no way of telling if a person is in duress. It may be able to detect the mood the person is in, but it doesn't know the reason for the mood change, such as fear caused by violent threats.
Here's something else to be concerned about - "Voice Pay won't reveal the false-acceptance and false-rejection rates for its system, however. It argues that consumer confidence will come from the fact that Voice Pay will guarantee all payments."
Great, now we know it's not 100% guaranteed. Claims to have a secure system which do not reveal details about their system ultimately are not in the best interest of the public. Sure, trade secrets are necessary, but not revealing the error rates makes me mistrust.
We don’t need a voice authentication or an iris authentication or a digital imprint one. We don’t need nothing that can be ‘replicated’.
We need an instant and unique ADN authentication. That’s it.
Voice.Trust for mobile payments
www.voicetrust.com is already global market leader for voiceprint enabled password reset solutions. So security of voiceprint enabled authentication solutions is at least proven by Vocie.Trust.
