Near-collisions and their Impact on Biometric Security (long). (arXiv:2205.04229v2 [cs.CR] UPDATED)

Biometric recognition encompasses two operating modes. The first one is
biometric identification which consists in determining the identity of an
individual based on her biometrics and requires browsing the entire database
(i.e., a 1:N search). The other one is biometric authentication which
corresponds to verifying claimed biometrics of an individual (i.e., a 1:1
search) to authenticate her, or grant her access to some services. The matching
process is based on the similarities between a fresh and an enrolled biometric
template. …
