Implementing a successful open banking architecture is critical for a bank to fully leverage the benefits of open banking. Here are some of the standards and specifications that different countries around the world follow: Considering all the above key requirements and how the different regions have met these requirements, we have created WSO2 Open Banking. If the solution doesn’t meet the expected customer experience, no one will use the products and services that are provided through the open banking platform. So then the third parties can consume those APIs and generate new services to the bank’s customers. Our article on Strong Customer Authentication provides more details. In addition, about the system architecture is so important that it has become the foundation of the system analysis and design is also discussed. Banking System Data Flow -Context Diagram. In the same way, the API developers of the bank need to have a proper way to create and version APIs and manage the lifecycle of the APIs that are exposed by the bank. These WSO2 products are well used and well tested with different customers and use cases around the world. endstream endobj startxref The user stores can be of different types such as LDAP, AD or JDBC and different users should be able to provide different access rights. Redirect approach is where the bank user is redirected to the bank’s authentication portal from the third-party application. (BIAN) is an independent, member owned, not-for-profit association to establish and promote a common architectural framework for enabling banking interoperability.It was established in 2008. Especially when making payments through the open banking platform, frauds can happen. However it isn’t just about exposing APIs and implementing a consent management layer, there are a lot of other requirements when implementing an open banking platform such as API management, API security, and other functional and operational requirements. Three ways have been identified in different open banking implementations to revoke the given user consents: When a third party wants to consume APIs from banks they would typically come to the bank’s API store where they can explore existing APIs that are published and see what is available to develop their applications. ����Oy��E����$p_��wq�g��� Having to go through all the authentication steps iteratively can lead to bad user experience. These would improve the confidence of the third parties to use the open banking platform exposed by the bank. Authenticating users only via one authentication factor is not enough. To identify what the key requirements of an open banking platform are and how they can be implemented, selecting the right technology is a top priority. Everyone from your compliance officer to your open banking project manager to your CTO needs to have complete confidence in the open banking platform you choose. They might need to test those APIs before exposing them externally. If you wish to disable cookies you can do so from your browser.

The central business activity is the transaction processing system which handles the money flow between the accounts. API analytics can help see how the exposed APIs are performing and how they can improve. Once the bank receives the user consent, it will share the required information with the third-party application. YeLo Bank, a digital-only, mobile-first neobank focused on serving mass-market consumers, has won the AWS Startup Architecture Challenge of the Year 2020 India finals. These two layers are SOA (Service Oriented Architecture) based and Java compliant. Banking Information System Architecture Taking into account the nature and diversity of activities performed by banking institutions, information systems providing support have a high degree of complexity rendering it difficult to clearly delimitate their architecture. For example, ATM locations, branch locations, exchange rates, and interest rates can be exposed by means of open APIs. This is a Component diagram of Banking Management System which shows components, provided and required interfaces, ports, and relationships between the Current Account, Saving Account, Employees, Accounts and Balance. %PDF-1.5 %���� This type of diagrams is used in Component-Based Development (CBD) to describe systems with Service-Oriented Architecture (SOA). Different banks use different combinations of authentication factors from basic, SMSOTP, Vasco, fingerprint, voice, Facebook, Google, and more. Bank staff and bank users already reside in different user stores, and we would need to provide a place to keep the third parties.

The bank provides an interface for bank users to log in and revoke the consents. This redirection can be done either via a browser or via a mobile app. ATM Channel of Banking: In simple words The ATM is known as Automated Teller Machine. For many banks, replacing these systems may well be the best way to reduce complexity and support business growth. So then the third parties can consume those APIs and generate new services to the bank’s customers. The traditional banking model is undergoing rapid and significant transformation fueled by heightened customer expectations, a raft of regulatory mandates, and the convergence of emerging technology with new business models that blurs lines between previously distinct industries. There should be a capability to identify the risk level of a transaction and if it is low then the bank can exempt the user from having to go through all the authentication factors. When thinking about existing data and services there can be some set of data that can be exposed via open APIs. In addition to all of the above requirements, an open banking platform should provide proper API management capabilities to both third parties and API developers of the bank. Banks always carry the risk of choosing the wring system design or … The user interfaces, emails, alerts, reports and error messages of the API calls should also provide better user experience and everything should be according to the standard which is specified by the bank.
