A British technology company has come up with a voice biometrics solution – Voicekey – that it will promote as a way to secure m-commerce transactions.
Developed from research at Nottingham Trent University, Voicekey has patents pending worldwide. According to the developers, in an increasingly mobile digital age, the need to remotely verify the true identity of an individual in a user friendly manner is becoming ever more necessary.
The company points out that as we move beyond simple mobile applications, that allow remote access to email etc., to more sensitive m-commerce type applications, where we can order goods and make payments on the move so, this need becomes evermore critical.
The Voicekey software extracts key unique features from an individual's voice in order to create bespoke biometric classifiers (voicekeys) that can be stored in a central database or, more preferably, locally on a user’s smartphone devices. This classifier can then subsequently be used to verify the identity of an individual.
In a typical APP version, when first launched a user would enrol within the APP by repeating a simple pattern of words or numbers three times in succession in order to provide a good quality sample of their voice. Bespoke Voicekey algorithms then generate the user specific voice biometric classifier, which after encryption, is stored securely on the mobile phone.
In normal use, the Voicekey APP would then simply prompt the user to repeat a simple random pattern of numbers or phrases. The recorded verification voice sample will then be used, together with stored biometric classifier, to give a yes or no identification of the user.
Voicekey is claimed to have advantages over other verification technologies. These include:
Typical applications for the technology include:
