The First Of Its Kind

A touchless fingerprint solution that utilizes existing hardware

ONYXTM is a software-based authentication solution that uses a device's camera to capture and identify a user's unique fingerprint. A quick download and install enables touchless fingerprint access on just about any mobile device. Manufacturers can integrate quickly and easily, as it's entirely software-based.

ONYX forever changes the way businesses and users interact on mobile devices. We give businesses more flexibility in delivering their data, products and services, while providing customers with a game-changing combination of increased security, reliability and convenience.

Greater Accuracy

Images we capture from a mobile device's camera are "normalized" with our software resulting in more accurate fingerprint rendering and identification.

If your finger is dirty or it has a scratch, Onyx will still capture your fingerprint. Our software compensates for distortion by allowing adjustments in tolerance levels: if by default we're scanning 100 data points, we can lower it and still get a reliable match.


Better Reliability

Because Onyx is touchless you don't have to worry about the sensor getting dirt or oil build up over time, which causes reliability issues with touch-based sensors.

Another inherent problem with touch-based sensors is pressure. When various amounts of pressure are applied to a touch-based sensor the image collected can be distorted.  Onyx's touchless approach removes pressure from the equation.

We can reliably enroll 99% of the population - regardless of age or skin pigmentation.


Inherently Progressive

Mobile device manufacturers already have huge Research and Development departments working to constantly make their cameras better. It only makes sense to let them do the hardware improvements, allowing us to concentrate on making our software better and ensuring it’s compatible with the latest camera enhancements.

By putting our focus on software, not hardware, we are positioned to take advantage of emerging technologies. In the near future, other innovations such as 3D cameras, infrared technology, and ultrasonic sensors may allow Diamond Fortress Technologies to improve Onyx in ways never before thought possible.


Fast & Easy Deployment

Unlike the more common hardware solutions, Onyx is entirely software-based, which gives us the ability to deploy it faster than those that are hardware-based.

Because Onyx is a software library, we can bypass the manufacturing/warehousing/delivery/implementation issues our competitors are presently grappling with.



Developers and manufacturers looking to incorporate biometric authentication into their devices and systems can easily integrate Onyx without having to incur the expense of developing purpose-built hardware and concerning themselves with form factor redesigns.

This reduces cost and integration time so that you can get Onyx in the hands of your users faster than with typical hardware based touch sensors.

Onyx can also be integrated with your existing database/system.



Any time improvements are made and fully tested, the updated software can be pushed out right away to your end-users over the air. As hardware becomes more advanced, Onyx can capitalize on those improvements almost immediately.

Of course, additional functionality and user improvements can be distributed in exactly the same way.

Our OTA update system was intentionally designed to keep Onyx flexible enough to adapt to whatever the future has in store.

How it works

Onyx is compatible with both Android and iOS.

Finger Placement

Place two fingers together in view of the rear facing camera.

The Ellipse

Center the index finger inside the ellipse. ONYX will then auto-focus and auto-capture the fingerprint.



Diamond Security

Security Focused

Onyx quietly works behind the scenes to support secure, frictionless, anytime/anywhere authentication. It becomes the de facto means of proving you are who you say you are for all mobile-based business to business or business to consumer or personal interactions.

We never store your fingerprint. We take the image and convert it to a template using complex mathematical algorithms. The resulting template is stored in the secure layer of your mobile device. It can also be stored securely on an enterprise wide server.

The Code

Onyx is a software library written in C++, wrapped with Java for use on Android and Objective C for use on iOS, that acquires, processes, and matches images captured with the rear-facing camera of mobile devices.

Stored Template File Size

The size of the template varies by print, but it is approximately 188 KB, which allows for fast transfer speeds across any network.

Pixels Per Inch

The image resolution is an industry standard 500ppi; however, through our propriety image processing we achieve higher quality pixels that allow for greater accuracy and better FRR/FAR rates than other solutions.

Operating Range

The optimal operating range depends on the camera in your mobile device, however our tests have yielded the best results when the finger is placed 4-6 inches from the camera lens.

Matching Modes

Onyx allows an organization to use our built-in matcher and it also supports 3rd party matchers. The built-in matcher supports One-to-One & One-to-Many matching.

Camera Requirements

The minimum camera resolution required for Onyx to work properly is a paltry 1.5 megapixels, making it an excellent option for legacy devices.

Camera Controls

Controls include Auto-Focus, Manual & Auto-Capture, and Manual & Auto-LED control.

Compatible Operating Systems

Onyx is capable of working on a variety of operating systems including, iOS, Android, Windows 200/2003/XP/Vista/7/8, Linux and OS X.


Several types of encryption and security protocols can be supported from AES 256 and RSA for template encryption to SSL and TLS for transmission of the template over the network.
