Fingerprint in eKYC¶
Definition¶
Fingerprint biometrics in eKYC uses fingerprint capture and matching for identity verification, primarily in systems like India's Aadhaar where fingerprint data is available for authentication.
Fingerprint in Different eKYC Contexts¶
| Context | How Fingerprint Is Used |
|---|---|
| Aadhaar biometric eKYC | Customer places finger on certified scanner, matched against UIDAI database |
| Phone fingerprint sensor | On-device authentication (not identity verification against database) |
| Border control | Live fingerprint matched against passport chip or database |
| Law enforcement | AFIS (Automated Fingerprint Identification System) |
Aadhaar Fingerprint eKYC¶
| Aspect | Details |
|---|---|
| Capture device | Certified fingerprint scanner (STQC approved) |
| Template format | Minutiae-based (ISO 19794-2) |
| Matching | Against UIDAI central database |
| Accuracy | ~95% first-attempt success (lower for manual laborers with worn fingerprints) |
| Challenge | Worn/dry fingerprints in elderly and manual workers |
Key Takeaways¶
Summary
- Fingerprint is primarily relevant in Aadhaar-based eKYC (India) and border control
- Worn fingerprints in elderly and manual laborers reduce accuracy (~5-10% failure rate)
- Phone fingerprint sensors are for device authentication, not identity verification against databases
- Face is replacing fingerprint as the primary biometric for eKYC due to contactless capture
