A Practical Approach on Human Authentication Using Biometrics

This is a work in progress, presenting concepts and techniques directly related to the practical use of the Fuzzy Vault Scheme (FVS) biometrics cryptosystem on human authentication using biometrics. Many applications handle confidential information from their users. These information need to be handled in a secure way. One way of handling information securely is through cryptography, where the use of passwords is a common practice. Passwords are the weakest link on a conventional cryptosystem, because passwords can be easily copied or stolen. Biometrics is a way to overcome issues regarded the usage of passwords. Biometrics signals are more secure, but they also need to be protected. To protect biometrics signals one can use cryptography based on biometrics keys. But, due to the variability of the biometrics signal, biometrics cannot be directly used as cryptographic keys of a traditional cryptosystem. Cryptosystems that address to overcome these issues are called Biometrics Cryptosystems.
