Implement Biometric Capture (Fingerprint) in your Application

Implement Biometric Capture (Fingerprint) in your Application

These days, more and more websites are using biometrics authentication, especially fingerprint, as a form of identification and access control. This bring the question, what is wrong with using the username and password combination for login authentication?

While this traditional mean is viable in many identification systems, it has several disadvantages. For starter, it imposes a memory burden on users. For anyone who has been using the internet for a couple of months or more, he is almost surely to know the pain of recovering a forgotten password. But it is more than inconvenience. The password-based identification systems are vulnerable to user information leaking.

Biometric identifiers include fingerprint, palm veins, face recognition, DNA, and other distinctive, measurable characteristics. Since biometric identifiers are unique to individuals, they are more reliable in verifying identity than password-based methods.

This article will share some customers’ stories who integrated fingerprint devices into their application.

Usage Scenarios

From the communication history with our customers, I get the impression that Dynamsoft SDKs are widely used in the following two scenarios:

  • Authentication on login: The 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 headshot via a webcam and capturing fingerprints from a fingerprint device.

Dynamsoft provides SDKs for both webcam capture and fingerprint scanning.

TWAIN-Compatible Fingerprint Devices

Please note this is not a full list of TWAIN-compatible fingerprint scanners. It is just a list we gathered from our customers’ cases.
