Open Banking Architecture 101: The Principles and Non-Functional Requirements

Gain insights into Open Banking architecture and the AA Framework in this comprehensive guide

The Account Aggregator framework in India has emerged as a transformative force, bringing open banking to the forefront of the country's financial landscape. This innovative framework allows individuals and businesses to securely and seamlessly share their financial data across multiple financial institutions through a consent-driven mechanism.

By enabling the flow of real-time financial information, the account aggregator framework empowers consumers to have greater control over their financial data and facilitates the development of innovative financial services. It also fosters competition and collaboration among financial institutions, encouraging the creation of new and personalized offerings.

With the account aggregator framework, India is leading the way in embracing open banking principles, fostering financial inclusion, and driving a more efficient and customer-centric financial ecosystem.

What is Open Banking? What are its Major Characteristics?

Open banking refers to a system where banks and other financial institutions provide access to customer financial data through standardized application programming interfaces (APIs). It is characterized by the following key features:

Data Sharing: Open banking allows customers to share their financial data securely and directly with other banks, fintech companies, or third-party providers, with their explicit consent. This data includes transaction history, account balances, payment information, and more.

API Integration: Open banking relies on the use of APIs, which are sets of protocols and tools that enable different systems to communicate and interact with each other. Banks expose APIs that allow third-party developers to access customer data, initiate payments, and build new financial applications and services.

The Account Aggregator Framework enables secure access and at the same time automates the functionality of data sharing.

Let’s see the benefits for Banks in detail.

Improved Customer Experience

Open Banking is based on the increased interactions among consumers and partners through Omni-channels supported by API-based transmissions of data. Majorly backed by Open Banking Services and Analytics Service Platforms, the network leverages influential activities between the market and consumers.

It provides automated processing, and integration through an API framework to facilitate secure service communication and synchronization across the network.

Fully-Integrated Data Analytics

Bank’s AA Platforms leverage AI-driven analytics to cater to the needs of consumers. These events are stored in data lakes for future use. The integrated data fabric created by the AA framework enables flexible, reliable, and high-performance analytic processing leveraging all data resources available across the environment.

Increased Efficiency Using the Cloud

Banks need to ingest and process large amounts of data from multiple sources. Here, cloud-based AA solutions offer flexibility to accommodate the data with real-time processing aligning banking services with the dynamics of the real world.

What Should Banks and FIs Look for in AA Framework Solutions?

Technology Service Providers (TSPs) play a pivotal role in the success of AA Framework adoption for Open Banking in India. Their expertise in developing and integrating APIs, ensuring data security, managing infrastructure, and providing regulatory compliance support is crucial for enabling seamless and secure data exchange between financial institutions, data aggregators, and customers.

Major TSPs have platforms customizable to various Banks’ and FIs’ needs. Their role as technology enablers is instrumental in realizing the full potential of open banking, fostering collaboration, and transforming the financial landscape. So, here’s what Banks and FIs should look for in AA Framework solutions.

Factors to Consider for the Long Run

Security and Encryption - All sensitive data must be encrypted while in transit or should be stored in data lakes and private clouds and this includes authentication credentials. This should serve several purposes safeguarding the data, logging and monitoring remote access & securing authenticated encryption.

Scalability - The solution architecture must be able to serve large-scale deployments that would not only focus on customers' needs but also serve the future needs of a dynamic, growth-focused bank. It must provide a robust ability to scale and align with the business objectives as the banking system grows.

Performance and response times - Real-time processing, low latency, and throughput are necessary for banking architecture as they affect real parameters of banking that include card authorizations and transactions, payment transactions, fraud detection, and securities processing.

Compliance and Regulatory Support – AA Framework Analytics Partners assist in complying with the regulatory framework governing open banking. They should ensure that the implemented solutions adhere to data protection laws, privacy regulations, and other relevant guidelines set by regulatory authorities.

Services Required to Build AA Platforms

API Development and Integration - TSPs develop and maintain the necessary APIs (Application Programming Interfaces) that facilitate the secure and standardized exchange of data between financial institutions, third-party service providers, and customers. They ensure that APIs adhere to the specified technical standards and protocols, allowing seamless integration and interoperability.

Infrastructure Management - TSPs handle the management and maintenance of the technological infrastructure required for open banking operations. This includes server systems, cloud platforms, databases, and other components necessary to ensure reliable and uninterrupted access to financial data and services.

Features of Innovative AA Platforms

Consent Management Systems – Consent management systems that allow customers to provide and manage their consent for data sharing with financial institutions and authorized third-party providers. These systems ensure that customer consent is obtained and managed in a transparent and secure manner.

Data Analytics and Insights - Data analytics and insights services leverage the aggregated financial data to generate valuable information for financial institutions and service providers. These insights can be used for risk assessment, credit scoring, customer profiling, and developing personalized financial solutions.

For successful, open banking architecture, it is critical for a bank to fully leverage the benefits of the AA Framework in India. To identify the key requirements of an open banking platform you can get in touch with D2K’s Banking Fintech Experts for detailed roadmaps for AA Framework Adoption.
