TL;DR: Fingerprint biometrics improve user verification by turning unique physical traits into reusable identity templates, but they also create privacy, spoofing, and irreversibility risks when data is exposed, according to 1Kosmos. The governance issue is not whether biometrics work, but how organisations secure a biometric that cannot be reset like a password.
NHIMG editorial — based on content published by 1Kosmos: fingerprint biometrics and security implications
By the numbers:
- Only 5.7% of organisations have full visibility into their service accounts.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.
Questions worth separating out
Q: How should organisations use fingerprint biometrics without increasing identity risk?
A: Use fingerprints as one assurance factor inside a broader identity programme, not as a standalone trust decision.
Q: Why do fingerprint biometrics create different risk than passwords?
A: Passwords can be reset after compromise, but biometric traits cannot be changed.
Q: What do security teams get wrong about biometric anti-spoofing controls?
A: They often treat liveness detection as a complete defence.
Practitioner guidance
- Separate biometric assurance from account recovery Use fingerprints to support authentication, but keep recovery paths dependent on stronger proofing than a single biometric factor.
- Choose scanner technology against the attack model Do not standardise on one sensor class for every use case.
- Minimise biometric template exposure Store only what the matching engine needs, encrypt templates at rest and in transit, and reduce retention wherever the business process allows.

Fingerprint biometrics are a human identity control that only works when the entire proofing and recovery chain is trusted. The article correctly treats the fingerprint as a unique identifier, but the real governance issue sits around capture quality, matching thresholds, and what happens after enrolment. In human IAM, a biometric is only as trustworthy as the upstream identity proofing and the downstream account recovery process. Practitioners should read biometrics as an assurance layer, not as proof that identity governance has been solved.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.
A question worth separating out:
Q: Who should be accountable for biometric data governance and privacy?
A: Accountability should sit with the identity, privacy, and security owners together, because biometric programmes span authentication, storage, retention, and legal use. If those responsibilities are split, the organisation can end up with strong capture controls and weak data governance, which is where many biometric risks accumulate.
