How to select the right biometric technology?

Biometrics is gaining traction as businesses look for more reliable authentication methods for user access, e-commerce, and other security applications. Should your business, however, use biometrics? And, if so, which ones should you use and how should you go about selecting them? There is no ''the best" biometric solution. Different biometrics are needed for different applications.

How to select the right biometric technology?

Biometric technology is a field that no part of the IT industry can afford to ignore. From IT vendors to end-users, and from security system developers to security system users, biometric offers security benefits.


Each of these industries must weigh the costs and benefits of implementing such safety measures.



Depending on perceived user profiles, the need to communicate with other systems or databases, environmental factors, and a variety of other application-specific parameters, different technologies may be suitable for different applications.


1) User-friendliness: Some biometric systems are difficult to use. Users who have not received enough training may have trouble aligning their heads with a device for enrolling and matching facial models.


2) Incidence of errors: Biometric data is affected by two main causes of errors: time and environmental factors. As a person grows older, their biometrics can change. Environmental factors may either directly affect the biometric (for example, if a finger is cut and scarred) or interfere with data collection (for example, background noise while using a voice biometric).


3) Precision: Vendors often rate biometric accuracy using one of two methods: false-acceptance rate or false-rejection rate. Both approaches depend on the system's ability to restrict access to only approved users. However, depending on how you configure the sensitivity of the mechanism that suits the biometric, these measurements will differ significantly.

For eg, you might demand a closer match between hand geometry measurements and the user's template (increase the sensitivity). This will most likely lower the false-acceptance rate, but it could also boost the false-rejection rate. As a result, pay attention to how vendors arrive at quoted FAR and FRR values.



4) The price: Components are -

a) Biometric capture hardware;

b) back-end database maintenance computing power;

c) biometric system analysis and testing; installation, including implementation team salaries;

d) mounting, installation, link, and user system integration costs;

e) consumer education, which is often accomplished by marketing campaigns;

f) exception processing, which involves dealing with users who are unable to upload readable images due to incomplete appendages or unreadable prints;

g) productivity losses resulting from the implementation learning curve; and device maintenance.



5) Acceptance by users: In general, the less intrusive a biometric is, the more likely it is to be accepted. Certain consumer groups, such as religious and civil-liberties organizations, have, however, opposed biometric technology due to privacy concerns.


6) Essential security level: Organizations should decide if the application requires a medium, moderate, or high level of protection.

This option will have a significant impact on which biometric is most suitable. For low-to-moderate security applications, behavioral biometrics are usually sufficient; for high-security applications, physical biometrics are needed.


7) Stability in the long run: The stability of a biometric should be addressed, as well as the technology's maturity, degree of standardization, level of vendor and government support, market share, and other support factors. Technology that is mature and standardized has a greater level of stability.



Biometrics technology is still emerging. We hope that this blog will assist you in weighing all of your options while purchasing new biometric technologies.
