ABCD Analysis of Fingerprint Hash Code, Password and OTP based Multifactor Authentication Model

P. S. Aithal; Krishna Prasad

Authentication is the usage of one or multiple mechanisms to show that who you declare or claim to be. Authentication ensures that users are granted to some resources or services after verifying their identity. The essential characteristics of every authentication system are to provide high security for their users. Multifactor authentication model always improves or enhances the security compared to single-factor authentication model. This new model makes use of three factors-biometric Fingerprint Hash code, One Time Password (OTP), and Password. Fingerprints are not fully secret compare to passwords, because if passwords are leaked which can be easily revocable using another password and which is not true in case of fingerprint biometric security system.  If an authentication system uses only fingerprint biometric features, it is not easy to change fingerprint, because fingerprint is static biometric, which never change much throughout the lifespan. In this paper,  as per ABCD analysis various determinant issues related to Multifactor Authentication Model for Verification/Authentication purpose are: (1) Security issues, (2) User-friendly issues, (3) Input issues, (4) Process issues, (5) Customer Issues, (6) Service Provider issues, and (5) Performance Evaluation matrix issues. The constituent critical elements of Multifactor Authentication model determinant issues are listed under the four constructs - advantages, benefits, constraints and disadvantages of the ABCD technique and tabulated. The analysis has brought out many critical constituent elements, which is one of the proofs for the success of the new methodology
