Abstract
the security risks of Internet banking have always been a concern to the service providers and users. In this work we analyze user authentication methods being used in various online environments, such as internet banking, electronic transactions and financial services, to identify the characteristics and issues of such authentication methods in order to present a user authentication level system model suitable for different online services. We integrated multi factor authentication with multi layer authentication techniques in order to produce a standard layered multi factor authentication model suitable for different internet banking services based on risk assessment criteria. The produced model consist of 5 level in which each level contain a one or combination of authentication factors such as knowledge based, possession-based or Biometric-based factors. The model then enhanced by adding control information factors, specifically for levels (4, 5), in order to support layering needs. Our paper suggests standard model compared to multi layering guidelines and it shows improvement and fulfillment of authentication needs.
