The basics of biometrics

In order to compare biometric applications, it is useful to know something about the basics. In this article, we briefly outline the ‘basics of biometrics’ for you.

1. General definition of biometrics

Biometric features are unique, person-specific characteristics that allow a person’s identity to be established. Body characteristics eligible for biometric solutions are not, or not easily transferable to other persons. Unlike, for example, cards, keys and passwords. They are also not prone to fraud, such as photos and signatures. Biometric features can not be removed.

2. Commonly used biometric features

Commonly used biometric features include:

  • Fingerprints
  • Eye (retina and iris)
  • Vein pattern in the palm or finger
  • Face, voice and speech

3. Why biometrics?

Biometric data is not transferable to other people in the same way that cards, keys and passwords are. Secondly, biometrics are much less susceptible to fraud. Photographs, signatures and access cards are susceptible to fraud, which means that a person’s identity cannot always be established with certainty in the process. A third feature of using body characteristics for biometric applications is that they are basically non-removable.

4. Biometric techniques

To ‘read’ the body characteristics mentioned above, biometrics uses several techniques. Think of:

  • Photo and video camera technology
  • Pressure measurement
  • Heat measurement
  • Voice recognition
  • Computer technology

5. The benefits of biometrics in identification

The advantage that biometrics offers in security or access solutions is twofold. On the one hand, ease of use: you don’t have to remember anything or take anything with you. On the other hand, the level of security: identification based on biometrics is much less susceptible to fraud.

With identification, it has another added benefit. It is completely personalised so offers little to no chance of identity fraud.

Strong together! Biometrics are regularly used in conjunction with conventional forms of identification. This increases the assurance that you are dealing with the right person.

Property or knowledge or biometrics? They are super strong together!

So far, ‘property’ (think passport or card) and ‘knowledge’ (think password or PIN) have always been the main forms of identification and security. To achieve an even higher level of security, combinations of the two have also been common for some time (think a card with PIN). Biometric security is not only an alternative to these traditional forms of identification, but offers opportunities to create an extremely high level of security by combining all three forms.

Due to the explosive growth of cybercrime, the need for higher levels of security will increase enormously in the coming years, especially biometric security solutions based on vein pattern recognition.* Ironically, their implementation may actually create new...

Biometric access control and privacy: what does the GDPR say?

The GDPR (General Data Protection Regulation) has been in force since 2018, and this has not gone unnoticed. Many organisations still struggle with its interpretation. In our own field, biometric access control, the GDPR also has the necessary impact. The court ruled...

FAR and FRR: security level versus ease of use

FAR and FRR. Anyone looking to assess or compare the performance of biometric security systems cannot avoid these terms. In this article, we explain what FAR and FRR mean, how they affect each other and their implications for security level and ease of use. Let us...

5 common biometric techniques compared

The best-known forms of biometric security are the fingerprint and iris scan. In addition, facial recognition and vein pattern recognition (of both finger and palm) are also on the rise. In this article, we list the pros and cons of all these forms. 1. Fingerprint...

How does vein pattern recognition work

There are three forms of vein pattern recognition. Palm vein pattern recognition, finger vein pattern recognition (both of which work using so-called near infrared* light) and retina vein pattern recognition. 1. Palm vein pattern recognition The haemoglobin in your...
