Apparently, it takes us 45 seconds on average just to confirm who we are.
But by using computers to identify our voices, this authentication process can be cut to 15 seconds on average, saving the bank pots of cash and us lots of hassle.
Citi has just begun rolling out this kind of voice biometrics authentication for its 15 million Asian banking customers, starting in Taiwan, Australia, Hong Kong and Singapore.
Citi uses the "free speech" method to begin a more natural conversation with the customer immediately...
Free speech has another advantage: it's harder to fake a realistic conversation using recordings. With the passphrase method it's plausible that fraudsters could record a customer's voice as he or she says the phrase and then use this high-quality recording to try to spoof their way through security in future.
The drawback with the system is that banks need to obtain customers' permission before recording voiceprints.
From 2018, the European Union's General Data Protection Regulation will require organisations to say what data they collect on you, for which purposes, and to obtain your explicit consent.
Some customers say no, but usually only around a quarter, says Ms Thomson. Citi's Asian efforts seem to bear this out, with a 75% uptake so far.
And as the technology gets cheaper over the next five years, we could soon be talking to parking meters, vending machines, robot hotel concierges and driverless taxis, to pay for things and check in.
La voce delle persone è pubblica , il che significa che è facile da registrare / elaborare / riprodurre, quindi come può quel sistema essere più sicuro rispetto alle solite domande di sicurezza segreto ?
