Security Enhancement Techniques of The Fuzzy Vault: A Review
نویسندگان
چکیده
Security of a biometric system is of paramount importance considering increased commercial use for allowing access to sensitive areas. In this context protection of stored biometric templates is of particular interest as these templates are irrevocable once leaked. Fuzzy vault has emerged as a novel cryptographic construct for the protection of biometric templates. But like every other technique this scheme is rife with loopholes. To overcome these issues several security enhancement techniques have been introduced for the fuzzy vault. This paper discusses these security issues and the various enhancement techniques currently available for fuzzy fingerprint vault. Keywords— fuzzy vault, biometrics, security, security enhancement.

A collusion attack on the fuzzy vault scheme
The Fuzzy Vault scheme is an encryption scheme, which can tolerate errors in the keys. This leads to the possibility of enhancing the security in environments where these errors can be common, such as biometrics storage systems. Although several researchers have provided implementations, we find that the scheme is vulnerable to attacks when not properly used. This paper describes an attack on t...
