fuzzy commitment

Fuzzy commitment is a security method that protects sensitive data, like biometric information, by allowing some variations or errors in the data during verification. It combines the original data with a randomly generated secret, storing only a fuzzy version that can tolerate minor differences. When you later try to access the protected data, the system can still confirm your identity even if your input isn't exactly the same as initially recorded, thanks to this flexibility. This approach enhances security while accommodating natural inconsistencies in biometric or other data inputs.
