Biometric template protection using cancelable biometrics and visual cryptography techniques

摘要: Wide spread use of biometric based authentication implies the need to secure reference data. Various template protection schemes have been introduced prevent forgery and identity thefts. Cancelable biometrics visual cryptography are two recent technologies address concerns regarding privacy data, improve public confidence acceptance systems. is an important technique that allows generation revocable templates. As number instances limited once compromised they lost forever. templates be cancelled revoked like passwords innumerable times. Recently, various approaches utilize stored impart central databases introduced. This work attempts summarize existing in literature making these protect
