BioSign — Mobile Fingerprint Authentication

The smartest, most powerful mobile fingerprint algorithm.

Enquire

Suprema's BioSign is a fingerprint matching algorithm purpose-built for mobile embedded applications. Its two-step matching with Suprema's patented Entropy Point Pairing method delivers excellent authentication performance in the compact, resource-constrained environment of a smartphone or embedded device.

The deep-learning-based algorithm adapts to each user's fingerprint condition and authentication habits over time, sustaining accuracy and speed as the device ages and usage patterns shift. BioSign is sensor-agnostic — the same algorithm runs unchanged on capacitive and in-display fingerprint sensors of any size.

BioSign is licensed by Suprema to OEMs and device integrators. Suprema South Africa can connect mobile device manufacturers, IoT integrators and embedded-systems teams in South Africa with Suprema's BioSign licensing team for evaluation kits and integration support.

Industry Demands

The specific security and operational requirements Suprema's solution addresses in this sector.

  • Mobile-grade authentication speed and accuracy on resource-constrained hardware
  • Sensor-agnostic algorithm — capacitive and in-display fingerprint sensors
  • Adaptive matching that compensates for finger condition and user habit
  • Small footprint suitable for embedded operating systems
  • On-device matching with no cloud round-trip
  • OEM licensing model with technical support during integration

Deployment Scenario

A South African handset OEM building a regional mobile device adopts BioSign as the fingerprint authentication algorithm for unlock and in-app authentication. Suprema South Africa coordinates the evaluation licence, hands the OEM Suprema's reference integration kit, and routes deeper technical questions back to Suprema's BioSign engineering team.

Solution Features
