Biometrics: The Future of Security

Biometrics includes a variety of approaches for safeguarding identity-based on physical or behavioral traits. Some of the typical biometric approaches include:

• Fingerprints
• Face topology
• Iris structure
• Hand geometry
• Vein structure
• Voice
• Signature
• Keystroke recognition.

In recent years, biometric security has seen a sharp growth; largely due to the fact that many mobile users have become comfortable using tools such as fingerprint identification for access. For example, the touch ID biometric is present on Apple’s iPhone 5s and generations following, along with the newer iPads.

Biometrics offers several advantages over identification cards, passwords and PINs’ the most significant advantages are the requirement that the person being identified is physically present and the elimination of the need to remember codes or passwords. Currently, fingerprint authentication is the most common used via mobile. One report forecasts that rising demand for smartphones, tablets and wearable mobile devices that incorporate biometrics will drive a global market of 2.5 billion users with nearly 4.8 billion biometric devices by 2020. Most significantly, it is forecasted that within three years, biometrics will become a standard feature on smartphones as well as other mobile devices.

In the future, biometrics can potentially be even more secure by including keystroke dynamics. Keystroke dynamics are a biometric approach that utilizes both physical and behavioral traits by measuring each person’s keystroke dwell time and flight time. This is an attractive approach because it is very accurate and yet not very intrusive for a user, which are the two biggest challenges with using biometrics.

Due the requirement of the users physical presence, biometrics is an effective way to prove the true identity of the individual user. Yet, the biggest advantage of biometrics is also the biggest drawback. Biometrics collects and stores data, but not just any data. It collects the data about the person that makes them unique. Many people find this intrusive, violating and do not what their unique data stored. With the growth of biometrics, at what point does security become so personalized that option of privacy is potentially compromised to ensure protection? Is the future foundation of security reliant upon consumers’ submission to biometrics?

  1. Hi-I think that biometrics can be a great alternative to passwords. I am personally so overwhelmed with having so many passwords! I cannot keep up with all of the passwords I have for my various social media accounts, online banking, health insurance, e-mail, e-commerce sites I frequently shop on, etc. It would be so great if I could simply use my fingerprint to access whatever account I need, without having to remember my password. Not only is this easier, but I would feel more secure as I would be the only person able to access my accounts.


  2. Great topic selection with biometrics—it increasingly has become a big topic in technology and marketing.

    Keystroke dynamics are an intriquing new modality for biometrics. Keystroke dynamics, however, will never be a main stay in terms of authenticating users because it is a behavioral biometric. Your keystrokes vary depending on your mood and state of mind – when you are angry you tend to type faster and pound the keys. There is even a difference in how you type when you are actively thinking about what you type and typing stream of conscience.

    Additionally, a certain aspect of keystroke dynamics involves a key logger – a software program that actually records all of the keys you press. While the key logger for a keystroke dynamics program tends to only focus on a few key characters (d, f, l, a, and i), it is not difficult to imagine a key logger being left on to record all key strokes.


    1. Thanks for the insights in the flaws of keystroke dynamics! The main motivation behind this effort to study and implement keystroke dynamics is the fact that keystroke dynamics biometrics is economical and can be easily integrated into the existing computer security systems with minimal alteration and user intervention.

      If keystroke dynamics aren’t a good solution, what other biometric approaches can be utilized to protect consumers and verify identity?
