Apple's recent announcement about the release of its mobile wallet app—called Apple Pay—energized the mobile payments community. One reason for the spike of interest is Apple Pay's use of fingerprint biometrics as an additional layer of security in validating customers and their transactions. What may have gotten a little a little lost in the chatter that followed this announcement was another, related announcement. As reported in a September 19 FinExtra story, MasterCard (MC) announced it had completed a pilot project that used a combination of facial and voice recognition on a smartphone. MC said that the trial program—which involved MC employees around the globe conducting 14,000 transactions—had a successful validation rate of 98 percent.
The Apple and MC announcements together certainly show that the future of the additional security options on smartphones looks promising. As a recent post noted, consumer research has consistently found that consumers' largest concern about using mobile phones for financial transactions is security. But are biometric technologies ready for prime time? Will their application in the payments ecosystem really give payment providers more confidence that the person they are dealing with is not an imposter?
The latest generations of Apple and Android smartphones are equipped with fingerprint scanners, cameras, and microphones, which allow for the use of fingerprint, voice, and facial recognition. But limitations exist for each of the techniques. The Apple and Android fingerprint readers, for example, were compromised within days of their initial release. And facial and voice recognition applications work best in controlled conditions of lighting and with limited background noise—an unlikely environment for a smartphone user on the go.
But security experts agree that additional customer authentication methodologies—beyond the common user ID and password entry fields—increase the overall authenticity of transactions. Numerous companies are continuing to focus their research and development efforts on improving the reliability and use of their authentication products. So while there is no "one size fits all" authentication solution over the weak and easily compromised ID-and-password method, these biometric methods represent a step forward, and are likely to improve over time.
The Retail Payments Risk Forum is taking a close look at biometrics technology and its impact on the payments system. We are working on a paper assessing biometrics and authentication methodologies that will probably be released by the end of the year. We're planning a forum to be held this upcoming spring on mobile authentication technologies. And we're continuing to write posts on the topic in Portals and Rails.
Please feel free to contact us with your suggestions on biometric issues you would like to see us address in our continuing efforts.
