Abstract

We expect that the accredited certificate-based open banking, which is actively deployed in recent times, will solve the Galapagosization problem of the existing accredited certificate-based closed banking by supporting standard communication protocol and web compatibility. However, it is questionable how much the open banking will answer the security and usability problems of the existing closed banking. This paper is focused on analyzing the differences between the existing closed banking and the open banking, and then evaluates how much the security and usability problems of the existing closed banking are resolved by the open banking. The study firstly analyzes the security vulnerabilities raised in the process of providing closed banking services for the past 15 years or more, the countermeasures applied to enhance security, and the convenience impact of countermeasures. And then, the security and convenience of the open banking is inferred by analyzing the implementation difference between the closed banking and the open banking. The paper also briefly discusses how to improve the open banking to resolve the remaining problems of the open banking.
