The Potential for Biometric Facial Recognition and Authentication

For all the buzz that biometric facial recognition authentication technologies have generated, it is important to recognize that the technology is still in its relative infancy. This is important because the power and potential of its use are poised to provide incredible levels of safety and service across a broad range of verticals.

More than ever, that increased level of digital and physical security is greatly needed. So now, is the time for a realistic discussion of how to harness the potential for biometric facial recognition authentication to ensure its continued development includes safeguards and seizes opportunities.

Biometric facial recognition authentication is now a regular household technology. Replacing the finger-scan security feature on previous models, the facial recognition capability of the iPhone X has millions of users experiencing the technology for the first time. The user’s face is confirmed by 30,000 separate infrared dots and works in concert with a robust series of fail-safes to prevent false authentication, including a traditional password. But the iPhone version of the technology represents just an inkling of its scope and possibilities.

It is important to note, though, that biometric facial recognition exists for a reason. And that reason is its ability to remove identification from something you know (like a password) or something you possess (like a laptop or security badge) and augment it with who you actually are. When used as a second factor of authentication, biometrics represent a dramatic security improvement.

And as some of the conversation about the technology understandably focuses on privacy and other issues, there are a host of other potentials for it that have yet to be reaped. Consider the potential of facial recognition merely as a customer service tool, removed from the more hot-button concerns that can sometimes derail a discussion on a technology’s possibilities. It’s a measured place to begin the discussion because views and opinions of privacy shift dramatically between industries.

According to Oracle’s Hotel 2025 report, there is growing enthusiasm for facial recognition systems that could be used to identify and even interact with guests, with 72% of hotel operators expecting to deploy such technology in the next four years.

For health care providers — particularly in the areas of assisted living and for patients who suffer from Alzheimer’s, dementia or any type of cognitive impairment — facial recognition offers increased patient protection. If a patient wanders away from a facility with no identification, facial recognition can help quickly identify them and get them back to safety.

In education, school districts in Arkansas and New York are already looking to facial recognition technology combined with machine learning algorithms to identify people, objects and even behaviors that could present safety threats.

For public safety and security applications, the possibilities are truly limitless. But there is a second technological piece of the puzzle that needs further development.

To truly harness the power of recognition, artificial intelligence and machine learning can be optimized with biometrics. Video is not like other types of data. It can be sped up or slowed down for review, but without AI, that process is still cumbersome and time-consuming. According to the National Center for Education Statistics, up to 94% of public high schools utilize cameras capturing live streams, making it unrealistic to parse the information captured manually in real time.

To achieve the greater complexities of advanced applications, video must be converted to bytes. AI can then efficiently parse through that data to identify patterns, building a search index of events. While biometrics are currently sophisticated enough to determine and identify activity, it will take further innovation in AI to close that remaining gap. That capability is still a year or two away, but it will be a game-changing tool across a wide breadth of industries.

How this will align with the post-GDPR era of privacy concerns remains to be seen. But what is certain is that the level of privacy compliance will be far more reliable in a technology that is professionally developed and deployed with accountability rather than what we have now: confusing footage shot on a thousand different camera phones and then broadcast, uploaded or shared after an event or incident has occurred, with no context, accountability or reliability — and, most importantly, no privacy considerations at all.

The question is not whether we will be captured on film over the course of our daily lives. There are already billions security cameras worldwide, and millions more in everyone’s’ pockets. But we need to figure out the best way to responsibly enhance what is already a reality with a technology that will create greater levels of safety and service.
