Palm-vein scanning is biometric authentication that identifies a person from the vein patterns inside the palm. Infrared sensors capture these internal patterns, making them difficult to replicate or spoof. The technique suits high-security environments but remains uncommon because it requires specialized hardware. section 15.1.5 section 15.1
Palm-vein scanning is most appropriate when:
- A system needs contactless identity verification in a high-security setting. section 15.1
- The deployment can support dedicated infrared scanning hardware. section 15.1.5
- The organization accepts lower availability than fingerprint or facial authentication. section 15.1.5
Figure 15.1 Biometric authenticatation is a three-step process. First, a user registers their data. Then the user tries to authenticate and be verified by the system.
Follow the biometric authentication flow from user enrollment through authentication and verification before access is granted. section 15.1.5
