When Privacy and Security Matter Most,
You Need 4 Fingers TouchlessID

4 Fingers TouchlessID

4 Fingers TouchlessID is the world’s first multi-finger contactless biometric authentication system that works on unmodified smartphones. It is a significantly more reliable biometric than other mobile-based solutions, providing prints that are the equivalent of those captured on traditional flatbed scanners. Unlike facial recognition, it won’t fail under bright lights or in dim rooms. In noisy areas, it’s better than voice. And it’s more secure than using a single thumbprint.

Capturing all four fingerprints at once increases the complexity of the data collected, enhancing overall security well beyond partial prints, like those captured by sensor-based mobile fingerprint solutions.

4 Fingers TouchlessID works on any iOS or Android smartphone equipped with a 5MP rear-facing camera and LED flash. It doesn’t require any additional hardware or sensors and is ready to deploy within any custom app using VeridiumID’s SDK.

Here’s How it Works

Fingerprint Recognition with 4 Fingers Touchless ID

Veridium’s Computer Vision team developed 4 Fingers TouchlessID because a highly secure mobile fingerprint recognition biometric simply didn’t exist. The team’s approach uses a smartphone to capture a high-quality image of your hand, providing more data to ensure the integrity and complexity of the biometric vector. The more complex the biometric vector is, the more precise and reliable authentication is.

The Veridium team is working with the National Institute of Standards and Technology (NIST) to include 4 Fingers TouchlessID in the government’s certification program for contactless fingerprint capture. This will ensure compatibility with developing law enforcement and immigration fingerprinting standards.

Independent Accuracy Testing

Independent QA testing firm iBeta tested 4 Fingers against the Drug Enforcement Agency’s biometric standards for Electronic Prescription of Controlled Substances (EPCS) applications. The study found that the system met the False Match Rate of 0.0001 with 95 percent accuracy, surpassing the accuracy levels needed to be a strong authenticator for password and token replacement, medical prescriptions, and mobile banking.

Before Cuy Móvil could bring more affordable mobile phone plans to Peru, it needed to figure out how people could register the SIM cards they purchased from the mobile operator with government. That’s where Veridium came in.

Benefits of 4 Fingers TouchlessID

  • Extremely low False Rejection Rate of 1.0% at a 0.01% False Acceptance Rate

  • >500 DPI resolution, the same as high-end flatbed fingerprint scanners

  • Works under any lighting conditions because it uses the device’s LED flash

  • Works on standard smartphones – no additional hardware required

  • Liveness detection to prevent presentation attacks (spoofing)

  • Uses a simple interface that makes it fast and easy to authenticate

  • 4 Fingers provides high-quality prints for 1:1 or 1:n matching

  • Supports legacy fingerprint database matching, including Interpol, NIST, and more coming soon.
