Fingerprint biometrics: are current controls enough for IAM teams?

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.
