Enhance fuzzy vault security using nonrandom chaff point generator
We review state of the art techniques related to fuzzy vault, especially CRC-based fuzzy vault. We analyze significant flaws of CRC-based fuzzy vault, demonstrate blend substitution attack on vault. We suggest new schema in replace for CRC-based fuzzy vault, proposed one specific algorithm to implement our schema. Security analysis and practical experiments are reported. New schema limits previous CRC problems including blend substitution attack and improve authentication quality.
