Combining Crypto with Biometrics Effectively

The authors propose the first practical and secure way to integrate the iris biometric into cryptographic applications. A repeatable binary string, which they call a biometric key, is generated reliably from genuine iris codes. A well-known difficulty has been how to cope with the 10 to 20 percent of error bits within an iris code and derive an error-free key. To solve this problem, they carefully studied the error patterns within iris codes and devised a two-layer error correction technique that combines Hadamard and Reed-Solomon codes.
