We have previously discussed the current forms of biometric credentials and how markers are used to provide authentication. In this article, we will look at how biometrics are increasingly chosen as a reliable and secure method of identification, as well as potential future technologies.
What is the future of biometric technology?
Every day, people use facial or fingerprint biometrics to unlock their phone or access their apps. The EU Entry/Exit System (EES) is being introduced to attempt to streamline and speed up the usual delays international travellers experience when entering the European Union. British police forces have begun to roll out live facial recognition systems. Facial recognition uptake is rapidly increasing, with a predicted market growth from $6.94 billion in 2024 to $7.9 billion in 2025; an increase of 13.8%. Generally, experts believe acceptance of biometric credentials is expected to increase by 2030.
Potential benefits of further biometric uptake
If implemented properly, biometrics are a valuable addition to site security and access control setups. Even in a limited role, having biometric credentials to add multi-factor security allows for the unique markers of the user to reinforce their other credentials. They cannot be shared, and if tied to an audit trail, can give a very accurate identity linked to access events or attendance logs. This also increases the defensibility of highly secure sites or zones, as biometric credentials are much harder to steal or copy.
In a well-tuned system, the throughput of users through pedestrian chokepoints can be sped up dramatically. Without needing to type a long PIN or fumble in a bag or pocket to find a physical credential such as a card or key, the systems involved can automatically check and approve people on approach and allow or deny their access further. This can also help with the potential hygiene risks associated with multiple users using PIN pads or keys.
With the huge range of biometric markers, and the different combinations possible, the level of security from a full suite of biometric access readers would be incredibly difficult to deceive and could allow individuals a choice of biometric measurement. For example, Tensor's T32xx clocking station can use smart card/fob, fingerprint, or PIN, or our FaceStation facial authentication scanner which can also use smart card credentials.
Potential roadblocks to further biometric uptake
For all the advantages that biometrics can offer, sometimes these positives form parts of the criticism. One of the largest issues that biometric access control needs to overcome are problems around personal privacy. Privacy advocates often point to the personal nature of biometric data and the concerns around its collection and storage. Due to the immutable and permanent nature of biometric markers, if this data is compromised, the impact is likely to be higher than simply changing a password. Companies must work hard to earn the trust of the public and their customers; to prove they are a reliable and secure data controller. They can do this by applying for and being awarded international standards and accreditations, like the International Organization for Standardization (ISO) and others.
Other concerns are based on the danger of performance and misidentification. As the technology still feels comparatively new, the general perception is that biometric technologies are still unreliable or experimental. Some issues arise with perceived performance across demographics or different working conditions. Any issues with bias or accuracy need to be acknowledged and addressed. This was recently a concern for Essex Police, who needed to stop facial recognition deployments while an update was applied. Problems may also arise if someone is mistakenly given access or a legitimate user is locked out.
The final hurdles that biometrics must overcome are the potential loss of choice, and a possible slippery slope towards civil rights infringement becoming more prevalent, as biometrics begin to be used in ways beyond their original design, such as mass monitoring or profiling without individuals' consent. Furthermore, people who are uncomfortable with the idea of using their biometrics at their workplace may feel pressured to do so. Alternatives or Multi-Factor Authentication (MFA) systems such as a combination of PINs, smart cards, and biometrics (like Tensor's T32xx range) could all help to keep security high and concerns low.
What could the future look like?
General trends appear to show an uptake in biometrics, but whether one type or another will prove to be the most dominant is unclear. What is clear however, is that access control and biometrics that require smartphone access will probably be a forerunner. With approximately 60% of the global population using a smartphone, and the increasing functionality of Internet of Things (IoT) controls, user expectations are likely to mean access control systems will soon prioritize the user experience. A swift and simple process to gain access to buildings or make payments with a tool that most people always keep on their person is already a reality.
