The solution

Telos Shield is an innovative, law enforcement-focused mobile device application designed specifically for the NIST mFIT Challenge; it is powered by Telos’ touchless mobile device fingerprinting system and software development kit (SDK), ONYX. Telos’s patented technology involves methods to convert a finger image capture, process accurate images, and compare them to a predefined template such as touch-based livescan devices. The core of Telos Shield is the ONYX SDK which captures high-quality digital fingerprint images, leveraging existing camera sensors in various field conditions using commercially available off-the-shelf (COTS) mobile devices at consistently high-efficacy rates.

Key highlights

  • Telos Shield is powered by the ONYX SDK, which works on multiple mobile platforms
    • Image Capture - ONYX users Telos’s proprietary neural network, CaptureNet, to detect the fingers in the camera field of view, automatically capture them once they’re in focus, and segment each fingertip into a separate image file.
    • Image Processing - ONYX Core performs a normalization method on the captured images to return high contrast, high resolution, accurate fingerprint images.
    • WSQ On-Device – Integrated into the ONYX library is the ability to perform high-speed image compression via a NIST standard Wavelet Scalar Quantization algorithm on iOS or Android.
    • Image Output – ONYX contains methods to retrieve the fingerprint imagery for processing, storage, or transmission in various formats
    • AFIS Interoperability – The ONYX SDK provides several functions to facilitate integration with third-party on-server matching algorithms, and matching against enrollments from touch-based sensors, commonly found in an AFIS environment
    • The ONYX SDK is a fully customizable contactless fingerprint verification solution. Based on client specifications, the user interface application can be developed by Telos, or through a third-party license agreement, to integrate ONYX.
  • The Telos Shield app utilizes the mobile device’s GPS and camera to gather additional identifying data, such as face images or documents. It can save to multiple databases, cloud servers, local, LAN, etc.
  • The app automatically identifies which finger is captured and includes a verification feature to send fingerprint/face images for comparison to databases.
  • The app will automatically request a recapture if the image is of poor quality. Users can also manually request to redo a capture.
