The Case for Biometrics

Learn about options that will fortify your access control

Is your facility’s physical security at risk for breaches? Maybe you’re fed up with lost keys, ID swapping and tailgating. Perhaps your risk profile has shifted and you need to restrict access in ways you never had to before. Consider biometrics if it’s time to beef up your credential system. You can add a higher level of authentication by requiring occupants to present their hand, fingerprints, face or eyes to gain entry.

Specify with Purpose
Security risks morph over time, requiring that you stay on top of threats your facility could experience. Adding biometrics should be driven by a verifiable security need. Companies that use one of these robust systems routinely cite concerns such as international and domestic terrorism, theft, data breaches, and occupant safety, says Paul Penzone, Managing Director of Operations and Program Development for ABM Security: “It comes down to protecting people, product, and property.”

Consider what goal or objective a biometric credential will satisfy for your building. Deploying this technology can improve security in numerous ways:

  • Use identification that cannot be forgotten by the carrier
  • Require a token that is expressly difficult to duplicate
  • Eliminate manual badge checks
  • Remove the possibility that a credential can be passed to another person
  • Add a secondary level of identification
  • Reduce costs associated with keys and cards
  • Limit access to a select group of occupants or areas within your building
  • Minimize your security risk profile
  • Enhance corporate accountability

A biometric ID can also serve as a master credential. Consider that an average employee may be issued a key, a photo badge, a PIN code, and a smart card. A single occupant could have up to four methods to gain access, not including guards at any checkpoint.

Dig Deeper Into Biometrics

Did you know biometrics are more than fingerprints and iris scanning? Learn more about the many biological markers that can serve as a unique identifier.

Despite security gains, biometric data can also raise significant privacy concerns. Use the existing legal framework to assure occupants that their data will be protected. Learn More.

“Biometrics provide an opportunity to standardize a credential methodology that spans multiple access systems,” says Sean Ahrens, Global Practice Leader for Security Consulting and Design Services with Aon Global Risk Consulting.

You also need to decide if your biometric system will verify or identify enrollees, Ahrens adds. A one-to-many match means that a presented credential will be compared to all of the other templates on file, essentially identifying the individual and giving them access according to the permissions associated with their profile. A one-to-one match will simply verify that the presented credential is confirmed for entry.

If you aren’t sure whether biometrics should be used for your entire population or a subset of employees, refer to your security risk assessment. You need to decide which threats your organization can tolerate and those that are necessary to address, says Penzone. Look for ways biometrics will minimize inherent risks as well as create efficiencies and cost savings.

Establishing the impact of adding biometrics will also help you justify the upfront expenditure required.

“Weigh the investment in this advanced form of security vs. the detriment of not having it,” advises Penzone. “Beyond the immediate impacts of an act of violence, how would an event affect your company’s bottom line in terms of reputation and long-term stability?”

As you forecast your budget, make note that any biometric option will need to be upgraded after five years, Penzone adds. Continual refinement of the technology will surpass previous systems in their matching capabilities within a matter of years.

Fingerprints Are a Constant Even as We Age

We accept that our noses and ears will lengthen as time marches on, but what about changes to our fingerprints? The unique pattern of ridges on our fingers have long been used by forensic experts with the assumption that they remain static over the years. A study completed by Michigan State University faculty and published in the Proceedings of the National Academy of Sciences confirms that fingerprints are fixed. Using multilevel statistical modeling, the records of over 15,500 apprehended subjects were studied over time periods ranging from 5-12 years. Adults of varying age, race and gender were included. The empirical data found that papillary patterns are relatively stable apart from limited changes caused by physical damage such as scars. This cements fingerprints as one of the most stable biometric marks.

Ensure Successful Enrollment
Biometrics can present a small learning or culture acceptance curve with employees. Many organizations select fingerprints because the public already has a basic understanding of how they work and has more confidence in its track record than other biometrics that have only recently been commercialized, notes Penzone.

Hand geometry may also be easier to transition to than others. People’s hands are readily visible at all times and this form of identification may be viewed as less intrusive than other forms. However, hand geometry doesn’t have the same degree of individuality as other biometrics – a person’s hand could swell from something as basic as retaining fluids after a salty meal or conditions such as arthritis or pregnancy, much less an injury, Penzone says. He suggests pairing hand geometry with another layer of verification such as a PIN pad, photo ID, or card reader. Ahrens adds that at the very least, have every individual enroll both hands so they can still have access if there are any minor changes.
