Earlier this summer, MasterCard announced a new multifactor authentication option for its cardholders: the selfie. Customers will soon be able to incorporate a selfie and facial recognition software into their accounts. The pilot program starts in the fall and will incorporate fingerprint scanning as well as facial recognition. Users will need to download an app to their smartphones to enable the new authentication methods, but if used successfully, the process should strengthen account logins and reduce the risk of identity theft.

Certainly, fingerprint identification has become more popular; readers are now found on most new smartphones. But getting this tool adopted by the B2B world might take some time, especially given the reluctance that many IT managers have over these technologies.

Tony Maro, the CIO for West Virginia medical records software vendor EvriChart, explained some of the possible benefits — and disadvantages — in an interview with Security Intelligence. “This may help reduce some online fraud. But it could be a mixed bag,” he said. “This isn’t about preventing people from stealing your credit card number. It’s about stopping the consumer from contesting purchases as a way to avoid paying for them.”

Another issue to consider is what happens to the digitized facial and fingerprint databases. Implementing these authentication measures gives enterprises the ability to collect the biometric data of potentially millions of individuals — and that information would be a gold mine for cybercriminals.

“This now becomes just another piece of data about you that’s going to be leaked in a data breach,” Maro explained. The storage of this data could become an issue for privacy advocates and yet another data store of personal information that needs to be tracked by intrusion detection and firewall software.

Finally, there is the reliability of the underlying technologies, which could be holding back companies from widespread adoption. “One-third of the time, my fingerprint still doesn’t unlock my cellphone,” said Maro. This could be why few of the multifactor or single sign-on vendors currently offer support for smartphone fingerprint readers. Part of the problem was that both Android and iOS didn’t have very robust application programming interfaces to support their readers until relatively recently, but the rollout has still been slow.

And facial recognition software is still not very accurate: Google’s software, for example, frequently misidentifies dogs as horses and kangaroos. “I’ve personally had a photo of Patrick Stewart autotagged as me on a friend’s Facebook stream once,” said Maro. While this may not seem so egregious at first glance, it’s a microcosm of the larger problems related to biometric authentication.

Still, the MasterCard selfie experiment in multifactor authentication is worth following when it is introduced this fall. Should this method of biometric authentication take off, it could soon be implemented at other institutions for security involving customers and employees alike.

How to Keep Your Secrets Safe: A Password Primer

There are two kinds of companies in the world: those that have been breached by criminals, and those that have been breached and don't know it yet. Criminals are relentless. Today’s cyberattacks have evolved into high-level espionage perpetrated by robust criminal organizations or nation-states. In the era of software as a service (SaaS), enterprise data is more likely to be stored on the cloud rather than on prem. Using sophisticated cloud scanning software, criminals can breach an enterprise system within…

Making the Leap: The Risks and Benefits of Passwordless Authentication

The password isn't going anywhere. Passwordless authentication is gaining momentum, though. It appears to be winning the battle of how companies are choosing to log in. Like it or not, the security industry must contend with both in the future.  But for some businesses and agencies, going passwordless is the clear strategy. Microsoft, for instance, has recently stopped forcing users to use a password to access their account, which allows access to a wide range of Microsoft business and personal…

Old Habits Die Hard: New Report Finds Businesses Still Introducing Security Risk into Cloud Environments

While cloud computing and its many forms (private, public, hybrid cloud or multi-cloud environments) have become ubiquitous with innovation and growth over the past decade, cybercriminals have closely watched the migration and introduced innovations of their own to exploit the platforms. Most of these exploits are based on poor configurations and human error. New IBM Security X-Force data reveals that many cloud-adopting businesses are falling behind on basic security best practices, introducing more risk to their organizations. Shedding light on…

Why Your Success Depends on Your IAM Capability

It’s truly universal: if you require your workforce, customers, patients, citizens, constituents, students, teachers… anyone, to register before digitally accessing information or buying goods or services, you are enabling that interaction with identity and access management (IAM). Many IAM vendors talk about how IAM solutions can be an enabler for productivity, about the return on investment (ROI) that can be achieved after successfully rolling out an identity strategy. They all talk about reduction in friction, improving users' perception of the…
