The new series of Rip Off Britain begins this Monday on BBC1 resuming its mission to expose shams, scams and poor customer service.

In this series I look at how failures in Vodafone’s billing systems and customer services have left subscribers out of pocket and with costly black marks on their credit history; also I investigate how freely available information might be used by identity thieves to build up detailed profiles of their victims.

One item that I hope to be covering more of is the future of passwords.

Like a stuck record, over the last four or so seasons on Rip Off Britain I’ve made the point again and again about the importance of good password hygiene to minimise the risk of hacks.

But recent developments in voice biometrics technology might be part of a move to make our live online much safer. In fact, customers of some major UK banks and service providers are already using just their voices to securely log-in to their online accounts.

The software claims to analyse around one hundred different behavioural and physical characteristics of our voices (for example accent or length of vocal folds) and is being used by customers of TalkTalk and HSBC among others. Its developer, Nuance, says the technology is so sophisticated that it can even distinguish between identical twins.

We took a special version of the voice recognition app to the BBC pop up shop at the Trafford Centre in Manchester to discover whether shoppers there felt secure using their voice as their password.

Rip Off Britain airs on BBC1 Monday to Friday from 12th September at 9.15am.
