BIOMETRICS AND BIOMETRIC TECHNOLOGY

Biometrics are the unique, measurable physical and behavioral traits of a person. Biometric technology is widely used: when you look at a camera to cross a border; make a smartphone payment; use your voice to confirm your identity; enroll your fingerprints to get a national ID card or register for voting; or even confirm you’re a device owner by the way you hold your smartphone. For almost two decades, Daon’s researchers have led the way in developing and refining powerful authentication solutions that have biometrics at their heart.

 

Why biometrics for authentication?

Biometrics are ideal for authentication because users don't need to remember complicated passwords or carry additional tokens. Biometrics also prevent the sharing of authentication credentials, unlike passwords and other factors that aren’t uniquely linked to a person.

 

Why mult-factor biometrics?

Each biometric has its own advantages and disadvantages for specific scenarios and use cases. Multi-biometric solutions are highly configurable and can greatly enhance flexibility; they allow different user convenience and security trade-offs to be made.

Each single biometric factor (e.g., face, voice, fingerprint) has its own advantages and disadvantages for specific scenarios and use cases. But multi-factor biometric systems are highly configurable and can greatly enhance flexibility, as they allow users to steer their own authentication journeys within the security parameters set by the organization. In addition, this flexibility allows organizations to make different convenience and security trade-offs as precise use cases and circumstances warrant.

Daon’s IdentityX platform offers a choice of biometrics to our customers, which greatly enhances user experience, acceptance and adoption. IdentityX (biometric technology platform ) also enables the use of biometric fusion, in which several biometric factors are combined to further boost performance.

 

Key biometrics for consumer applications include:

  • Face: using a camera to capture an image and authenticate a user based on the features of their face.
  • Voice (speaker recognition): using a microphone to capture a voice sample and authenticate a user based on their vocal characteristics and speech patterns.
  • Fingerprint: using a fingerprint capture sensor to authenticate a user based on the features of their fingerprint.
  • Palm: using a camera to capture an image of the palm and authenticate the user based on the lines of the palm's surface.
  • Behavioral biometrics: using the behavior of a user to authenticate them, e.g., by analyzing keystroke dynamics (a person’s unique typing rhythm).
  • Iris: using a camera (with appropriate illumination), where an image of the iris portion of the eye (i.e., the colored portion) is captured and the user is authenticated based on the pattern of the iris.

 

In addition, when biometrics (something you are) are combined with something you know (a PIN or passphrase) and/or something you have (a key or token) it is referred to as Multi-Factor Authentication (MFA).

Biometrics: on-device or on a server?

Biometric technology uses algorithms that can run on a user's personal device, on a server, or both. On-device algorithms are convenient, as they can work offline and provide instant guidance and results. But server-side solutions can take advantage of vast computing power to improve accuracy, perform identification tasks, and allow better auditing.

Daon strongly recommends choosing a biometric technology platform like IdentityX that can support both device- and server-side biometric matching.

 

Daon can help you to maximize your biometrics solution

In order to achieve optimal configuration for each different scenario, it’s important to measure the accuracy of each biometric, using a large collection of representative samples. Daon has benchmarked hundreds of biometrics algorithms: find out how we use this knowledge and experience to help our customers maximize the performance of their solutions. The Daon research team continuously evaluates, configures and combines biometric algorithms for different real-world deployment environments. Learn more about our Biometrics Research Lab.
