Biometric templates are irreplaceable—you can't change your fingerprints if stolen. FHE provides the strongest protection, keeping templates encrypted throughout matching.

Protection Methods

Cancelable biometrics apply irreversible transformations. Biometric cryptosystems bind templates to keys. FHE enables encrypted matching without exposure.

H33 Approach

Templates never exist unencrypted on our servers. FHE matching protects throughout the verification lifecycle.
