SOLUTIONS
Fingerprint Data & Image Solution
A solution that integrates tenprint card digitization, fingerprint image editing, and fingerprint data management assets to each client's requirements.
A fingerprint system depends on digitized paper cards, readable fingerprint images, and data management connected to a recognition engine. We keep three assets, tenprint scanning, fingerprint image editing, and dedicated fingerprint data management, as a common base and tailor the operating environment, screens, and integrations to each client. Fingerprint recognition and matching run through commercial SDKs and external engines, and preprocessing such as fingerprint image enhancement is developed to each project's requirements.
Architecture
SUB-SOLUTION 01
Fingerprint Template Data Management
A dedicated management system that stores and searches fingerprint templates and metadata. Original fingerprint images and matching templates are stored separately, and templates are indexed for matching searches. Matching algorithms are provided through commercial SDKs and external engines.
- Template indexing — template indexes for matching searches
- Encrypted storage — ARIA-256-GCM, a Korean standard algorithm (our STRCrypt library; not a KCMVP-validated module)
- Metadata search — registration date, collection context, resolution, quality score
- Separate storage of original images — template DB reserved for matching indexes
- Standard template formats — ANSI/NIST-ITL and ISO/IEC 19794-2 input and output (compatibility per integrated SDK)
SUB-SOLUTION 02
Tenprint Scan & Source Data Generation
Tenprint cards are scanned and converted into standard source data for recognition engines. The scanning core segments each finger, normalizes resolution, and applies WSQ compression, and also provides paperless scanning functions including image scanning, viewing, encryption and decryption, and quality control. The same core is applied to large-scale document digitization projects.
- Document scanning and registration — single- or double-sided, color, grayscale, or black-and-white input
- Automatic tenprint card segmentation — per-finger area detection and cropping
- Automatic 500 DPI conversion — resolution measured and normalized to the standard
- WSQ conversion — saved in the standard fingerprint image compression format (WSQ)
- Search and dedicated viewer — search by condition, encryption and decryption protection, Excel and PDF export and printing
- Scan quality control — task totals and status views
SUB-SOLUTION 03
Fingerprint Image Editing
A dedicated fingerprint image editor providing adjustment, correction, and automated image processing. Edited output is saved in WSQ format for downstream recognition and matching.
- Dedicated fingerprint image editing — WSQ format applied automatically on save
- Image formats — JPG, PNG, TIF, BMP, WSQ
- Task-focused interface — tools shown for the selected function
- Automatic filters — selectable fingerprint-specific processing filters
- Automatic task history — undo and redo
