6 Challenges with Non-Phone-Based Biometrics

Text

In my previous blog post, I talked about the rise of biometric authentication in typical payment environments. That market is currently dominated by phone-based biometrics where consumers authenticate the transfer of payment information on their device via a fingerprint scanner or face ID. For the merchant, it is a simple contactless transaction.

Non-phone-based biometric payments, however, are more complicated. They generally require merchants to own payment terminals that are equipped with hardware and software powerful enough to read biometric data. While interest in non-phone-based biometric payments are present in certain countries around the world, implementations pose many challenges.

Lack of Standards Make Rollout Challenging

Security standards are critical to the widespread adoption of any technology. Today, all the biometric payment solutions are tied to a single provider, each of which chooses to set its own standards. The privacy of personal data is enshrined in protective laws in almost all jurisdictions and these laws often lag technical change. Whilst the principles and purposes of data protection laws are consistent, their application and specifics are not necessarily. Both factors make widespread rollout challenging for any technology provider.

Concerns Over Biometric Data Privacy

Biometric data privacy a major market inhibitor. In many countries, we have seen concerns from consumer groups and governments where biometric cameras have been used for security or marketing purposes and governments also remain cautious over the creeping commercialization of such data.

Strangely, while consumers are expressing strong hesitancy about their image data being held for non-phone-based biometrics, the level of concern on the phone is far lower even though data is often held in the cloud. Maybe this is because many of us see our phone as an extension of ourselves – our brain’s external hard drive.

Biometrics Are Hard, But Not Impossible to Crack

Hackers have shown that it is possible to fool security systems that depend on fingerprint and even iris scanning with low-tech solutions based on high-quality photographs. One, for example, was able to beat an iris scanner simply by sticking a photograph of an iris to the inside of a hard contact lens to emulate the shape of an eye. Another popular video shows a shopper in China using face recognition at a self-service kiosk – as she bends down to tie her shoelace, instead of the camera scanning her face it simply recognizes the man behind her in the queue who is distracted by his phone and is billed for her purchases. The serious issue with biometrics is that, unlike with a password or token, once your face or finger has been compromised you can’t simply change it to another one.

Costs Are High for Non-Phone Based Facial Recognition

Most solutions in use today need a high-quality camera, considerable processing power and greater internet bandwidth. Facial and iris reading also depends on the right ambient light conditions, making the technology difficult to roll out in many circumstances. Cameras usually need to be mounted at face height which can be challenging in an in-store environment. All these conditions, though achievable, are expensive to implement and are difficult to roll out.

Limitations with Face Recognition

Facial recognition has come a long way but there are still many challenges with the technology when it comes to non-phone-based devices. From a payment environment standpoint, ambient light is a key factor since bars are often dark and retail stores can be overly bright in North America. This can govern what type of businesses opt for this technology. Another key limitation with facial recognition technology is skin tone. Research has shown that facial recognition is more accurate for white males and considerably less for dark skin toned females. One of the common inferences from the research reveals that the AI behind the platforms often uses the internet for source “learning” comparison data. As the population of faces on the internet is more skewed towards white and male images, there is a correspondingly more robust data set. There are also concerns for disabled users for more obvious reasons as well as countries where face coverings are common (although iris recognition is a potential solution here). In short, facial recognition is far from universal.

Fingerprint Adoption Is Likely to Be Set Back By COVID-19

Attitudes to physical contact have changed since the COVID-19 pandemic and the acceptability of public fingerprint readers may be affected for the foreseeable future. Fingerprint readers on personal phones, on the other hand, are not affected by this.

Future of Non-Phone-Based Biometrics

In markets such as China, where the adoption of facial recognition is high, special terminals equipped with super-high-resolution cameras and extra processing power can enable acceptance. However, I believe that the widespread international availability of such technology will depend on market standards. In countries where there is a lower penetration of smartphones, there is a lot more interest in a fingerprint as a relatively low-cost way to identify a consumer. Wider adoption of this into mainstream payments will depend on technology standards and on people’s willingness to use something touch based.

We expect to see more use and acceptance of non-phone-based biometrics over time as standards for it emerge and consumers are satisfied with the security and reliability of the experience but in the meantime, the phone-based model provides a very easy bridge.
