Security is an ever-present concern in today’s world. Increasingly, we are seeing how biometric
authentication, such as fingerprint identification, facial recognition, or DNA, is being used to enhance security systems.
Thanks to the prevalence of smartphones with touchscreens and high-definition cameras, it’s easier than ever before to implement these additional security protocols. The general public is embracing the technology as an easy way to prevent unauthorized access to accounts. In fact, 52% of consumers want banks to add fingerprint scans to banking apps.
But biometric technology goes far beyond fingerprints and facial recognition. Currently, there is advanced research being done about new and exciting ways to confirm identity. From analysis of fingernails, earlobes, and keystroke patterns, there are endless methods that are currently being explored, and each biometric has benefits and drawbacks.
For example, DNA is the most reliable identifier, and it does not change over the person’s life, making it a valuable long-term solution. However, DNA identification is not useful in identifying people over the Internet or at a distance. For example, a person walking in an airport wearing a hat and sunglasses cannot be identified via DNA, but it would be possible to identify them using thermal facial recognition.
As explained in the below infographic that was developed by Avatier, some biometric identifiers create certainty, while others are used as secondary metrics that could be a part of multi-factor security protocol.
For example, identification via fingerprints is ubiquitous and long-term. This could be paired with a fingernail plate scan which scans the surface of the fingernail. Researchers are developing this secondary biometric method because of the potential benefits of having authentication that lasts only two months until the fingernail grows out. Transient identifiers such as these may be the way future IT managers make sure users regularly change their passwords.
Lean more about emerging and established biometric authentication methods, their history, and how they work.
