Fuzzy Vault with Iris and Retina: A Review
نویسنده
چکیده
Biometric systems play an important role in authenticating the identity of an individual. Such authenticated systems are still prone to attacks and securing them is an important issue. To overcome this, biometric based authentication is blended with cryptography resulting in a framework called fuzzy vault which provides a high level of security. Fuzzy vault is a biometric cryptosystem used for protecting private keys and releasing them only when the legitimate users enter their biometric data. Fuzzy vault provides better security with iris and retina, because of their higher stability and template longevity as compared to other biometric traits. This paper reviews the basic concept of biometric security, operations in fuzzy vault along with its advantages, limitations and its implementation with iris and retinal biometric traits.
