An introduction to Biometric Access Control solutions

An introduction to Biometric Access Control solutions

Learn how Zwipe experts answer some of the most commonly asked questions about Access Control solutions in the section below.

When it comes to secure processes, the term ‘biometric access control’ may sound highly complex and can often be difficult to convey. This means it becomes challenging for users to trust the latest secure technologies used for access control applications. Therefore, technical methods that eliminate risks and create trust are of high importance.

Here comes the use of biometrics to improve such processes. Zwipe Access, our biometric card solution based on fingerprint access control is a new and highly secure smart card solution. It is battery-less and fully compatible with market leading card-based access control infrastructures. It doesn’t require an additional biometric reader as fingerprint capture, extraction and comparison are performed within the card itself.

How does a biometric system recognize or identify a person?

Biometrics is a process of establishing a person’s identity based on his/her chemical, behavioral or physical attributes. Such systems work with already enrolled and stored biometric data of an individual that is generated by a special algorithm using suitable characteristics to create a biometric template. The system can then be used to identify the person with the biometric data stored in the system. 

How is Zwipe Access different from other access card solutions?

When it comes to secure access control solutions, security gaps must be identified and ruled out from the very beginning. Zwipe Access seamlessly integrates complex processes into a standard ID card with the help of cutting-edge technology using biometrics. It can be easily integrated into existing card reader infrastructures and end users’ biometric data are securely stored as a unique template only in the card.

With a biometric access control system, it’s far more difficult for someone to gain entry using someone else’s ID. This means that the cardholder’s biometric data never leaves the card, thereby, providing increased data privacy to the cardholder. With its unique capability and secure processes, Zwipe Access cards eliminate security gaps caused by borrowed, lost, or stolen cards.

What are the different biometric modalities that can be used for access control solutions?

A biometric system identifies users with their physical or behavioral characteristics. Biometric data is collected with a capture device, it’s then processed and characteristic biometric reference data is stored in a database or ideally in a portable data carrier, such as a smart card. This process is called enrolment. When the user wants to access the system, he or she presents their biometric trait again. Biometric probe data is then generated and compared with the previously recorded reference data. Access is granted depending on the similarity determined by a dedicated algorithm and the security policy of the application. 

There are various biometric modalities including fingerprint, face, iris, hand geometry, veins, voice patterns, or DNA data. These modalities have different advantages and drawbacks to certain characteristics including uniqueness, permanence, and collectability. Which modality is best suitable for a specific application scenario depends on how these individual characteristics are weighed.

A Biometric System-on-Card (BSoC) performs data capture, processing, storage, and comparison of biometric data within a smart card. Although other modalities may be possible for this system architecture solution, the majority of BSoC is currently focusing on fingerprint recognition.
