How to Implement Biometric Capture (Fingerprint) into your Application

A growing trend in identification and access control is the use of biometric authentication, especially from fingerprints as it offers more security and convenience that traditional user name and password identification systems. Some of the most common Biometric identifiers include:

  • Fingerprint
  • Palm veins
  • Face recognition
  • Retina
  • DNA

These biometric identifiers are unique to individuals and are more reliable in verifying identity than password-based methods. In this article, we share some customers’ stories who integrated fingerprint devices into their application.

Usage Scenarios

fingerprint scanner sdk The most common usage scenarios we see with our Dynamsoft TWAIN SDKs are:

  • Authentication on login — fingerprints are captured and uploaded to a webserver, where the images are compared against pre-existing data
  • Biometric data capture for enrollment — for each user, a profile is built, which involves taking a head shot via a webcam and capturing fingerprints from a fingerprint device

Dynamsoft provides SDKs for both webcam capture and fingerprint scanning.

  • If you are developing a .NET desktop application, you can use Dynamic .NET TWAIN and its webcam add-on.
