Introduction
Standard Revision Background and Technology Evolution
This standard, as a replacement version of GA/T 790-2008, reflects the development needs of fingerprint collection technology in the past 15 years. The main revision directions include: optimizing collection area parameters to meet the resolution requirements of modern automatic recognition systems, simplifying card layout to improve operating efficiency, and canceling the supplementary fingerprint frame to enhance the one-time collection quality.
Comparison of key technical parameters
| Project | 2008 version parameters | XXXX version parameters | Change range |
|---|---|---|---|
| Rolling stamp frame | 35×35mm | 38×38mm | +8.6% |
| Plane stamp frame | 90×90mm | 95×100mm | Width+5.6% Height+11.1% |
| Palmprint collection area | 180×100mm | 190×110mm | +5.6%/+10% |
Key points for implementation of the standard
Operation specification recommendations
- Use 120g white cardboard to ensure uniform penetration of the print
- Keep your finger parallel to the edge of the 38mm square when rolling the print
- Plane prints must cover the entire area of 95×100mm
Typical case applications
Tests conducted by the Material Evidence Center of a provincial public security bureau show that the new standard increases the fingerprint feature point extraction rate by 12.7%, especially the completeness of the papillary lines in the lateral palm print area reaches 98.3%, 9.2 percentage points higher than the old standard.
Technology Evolution Analysis
This revision reflects three major technology trends: 1) Biometric feature collection standardization is aligned with the international FBI EFTS standard; 2) Automatic recognition adaptation expands the collection area to meet the 600dpi scanning requirements; 3) Operational process optimization cancels the supplementary stroke link, forcing the collection quality to improve.
