SequenceCheck™ is an advanced API designed to ensure the accuracy and quality of fingerprint image data collected for government, civil applicant, immigration, or criminal databases. It performs fingerprint segmentation, sequence checking, and quality scoring, helping to maintain data integrity and improve biometric matching performance.

Key Features

Fingerprint Segmentation

• Slap segmentation: partitions multi-finger images into single finger images
• Single finger segmentation: extracts and centers fingerprint data, removing noise and dirt

Sequence Checking

• Verifies correct placement and sequence of fingerprint images
• Reports match scores between slaps and rolls for each finger
• Identifies non-matching slaps and rolls of the same finger

Quality Scoring

• Generates image quality scores based on contrast, brightness, size, ridge flow, and minutiae counts
• Supports tuning for specific scanning devices

Fingerprint Encoding

• Determines minutiae data and core/delta regions for matching
• Outputs data for application use

Palm Image Quality Check

• Measures leftness/rightness, full hand segmentation, and global quality scoring
• Compares upper and lower palm to ensure data consistency

API & Integration

• Well-designed, easy-to-use APIs (C, .NET, JNI, Web Service)
• Highly configurable, scalable, and extensible
• Supports all major image formats and major OS platforms
• Example programs and source code for integration
