A Secure Cancelable Fingerprint Authentication for Cloud Services

Traditional password-based authentication systems create difficulties for users while remaining vulnerable to security breaches. The solution under consideration establishes biometric-based cloud service access, which enables users to terminate their services whenever needed. The minutia cylinder code is a great local descriptor for fingerprint authentication in public databases. It meets security needs and protects privacy, while still using the advantages of biometric technology. The cancelable fingerprint template design has two key parts: a simple way to create cancelable features and a method for making adjustable, partial cancelable features. The first part employs encoding-nested-difference (XOR), while the second part contains a basic reindexing procedure. The implementation of the proposed template design has led to reduced public database storage requirements and time needs on FVC2002 DB1–DB3 and FVC2004 DB1–DB3, with a 0.21% false acceptance rate and a 0.2% improved EER, and TPR/TNR stood at 99% throughout testing. The system delivers improved security because both stolen biometric templates become useless along with the addition of new biometric samples during re-enrolment. The system implements multi-factor authentication by combining cancelable biometrics with multiple factors. The performance study demonstrates exceptional accuracy combined with minimum false acceptance and rejection rates, which makes it a good means for secure cloud access.
