BioSign 2.0

World's Best Mobile Fingerprint
Authentication Algorithm

Suprema BioSign™is optimized iteration of Suprema's world best biometric algorithm
developed for mobile devices to ovver unrivalled recognition accuracy and
ultra-quick authentication performance while accommodating multiple sensor sizes.


• 2-stage fast matching algorithm with patented “Entropy Point Pairing” method
• Optimal architecture for mobile embedded applications
• Hardware independent: free from hardware acceleration (ARM-NEON / GPU / DSP)
• No floating point arithmetic and all codes are fully written in C/C++


• Enhanced robustness to the variation/distortion of fingerprints by Suprema’s patented technologies
• Reconstruction of discriminative fingerprint patterns from various noises
• Unique pattern analysis technique to ensure consistent performance over low-quality fingerprints
(wet/dry skin, partial wound, crease)


• Intelligent self-learning algorithm to reflect users’ fingerprint condition and habit
• Highly compressive template to cover full finger area and variations
• Smart template management to enable algorithm to deal with variation and habit of user


• Sensor-specific pre-processing algorithm ( capacitive / optical / under glass (up to 300um))
• Sensor independent features and patterns
• Satisfactory FRR even with smallest sensor size (13 mm2)
• No dependency to the sensor shapes (square/rectangle)


The world’s fastest, most accurate
mobile fingerprint technology ever

BioSign 2.0 provides unrivaled authentication performance through advanced machine learning algorithm. The ultra-fast
matching speed can even be achieved with mid-to-low range smartphone processors with the highest security while
ensuring the lowest false acceptance rate (FAR)

When speed matters
