Digital Public Infrastructure: An Overview

Digital Public Infrastructure: An Overview


Digital Public Infrastructure (DPI) is emerging as a transformative force, set to redefine the functioning, communication, and advancement of societies worldwide. DPI, the bedrock of technological systems and networks, meticulously crafted and sustained by governments or public entities, serves as the linchpin in furnishing essential services and fostering seamless connectivity, access, and data interchange among citizens, businesses, and institutions.

At the heart of DPI lies an unparalleled capability to democratize access to indispensable services and information. By provisioning robust digital platforms and networks, governments pave the way to bridge the gaping digital divide, ensuring individuals across all socio-economic strata enjoy equitable access to education, healthcare, government services, and economic opportunities.

What is Digital Public Infrastructure?

Digital public infrastructure (DPI) refers to platforms such as identification (ID), payment systems, and data exchange systems, enabling countries to deliver essential services to their populations. Digital public goods (DPGs) include open-source software, AI models, open data, standards, and content, which collectively contribute to making DPI a functional reality. 

The open format of DPGs allows for free adoption and adaptation, providing countries with cost savings and digital sovereignty—control over technology and data—as they build their DPI. This digital sovereignty preserves a nation’s flexibility in decision-making and supports its pursuit of Sustainable Development Goals (SDGs), fundamentally reshaping traditional models for development cooperation.

While proprietary solutions currently dominate the landscape of digital public infrastructure, concerns about contractual lock-ins and interoperability issues have prompted countries to explore open-source alternatives. 

Governments have the opportunity to embrace digital public goods with both technical and financial support from development cooperation partners, and they can seek assistance from the private sector as needed. Development partners can contribute significantly by addressing core challenges such as coordinating multilateral efforts, enhancing public procurement processes, ensuring financial and project continuity, and dismantling silos to facilitate collaborative development.

The Applications of DPI and the Technology that Enables It

Digital public infrastructure encompasses a vast number of areas where the application of this technology has influenced advancements:

Digital Identity Systems

The National ID System streamlines identification processes by utilizing unique biometric data such as fingerprints or facial features. This enhances security and accuracy in identity verification for various public services, from voting to accessing government benefits. Citizens benefit from a more efficient and secure means of proving their identity. Biometrics enhances security by providing a reliable method of authentication. Encryption is employed to safeguard the stored personal information, ensuring that unauthorized entities cannot access or tamper with sensitive data. 3G/4G/5G networks enable real-time verification, and standardization ensures interoperability across systems.

Digital Payments:

Digital payment systems, facilitated by digital wallets and secure encryption, revolutionize financial transactions. Citizens can conveniently and securely make payments, transfer funds, and conduct transactions online, promoting financial inclusion and reducing the reliance on traditional, paper-based methods.

Digital payment systems rely on digital wallets, which securely store payment information and facilitate transactions. Digital wallets use encryption to protect financial data during transmission, ensuring that sensitive information is not intercepted by malicious actors. This technology combination enhances the convenience and security of financial transactions. 3G/4G/5G networks provide connectivity for mobile payments. AI/ML analytics algorithms detect and prevent fraudulent activities.

Digital public infrastructure

Land Records:

The modernization of land records systems involves digitizing land records, conducting surveys for accurate updates, and integrating these records seamlessly with registration processes. Technologies like GIS, cloud computing, and mobile applications are employed to manage data efficiently. GIS utilizes spatial data for efficient mapping, security features protect land data and open data initiatives enhance transparency by making land records accessible. The transition from paper-based to digital systems simplifies property transactions.

Equipped with digital infrastructure, modern record rooms serve as centralized repositories, ensuring easy verification and reference for stakeholders. The overarching impact includes a decrease in property disputes, heightened efficiency in government administration, and an improved business environment.

Tax Network:

A digital tax network enhances the efficiency of tax-related processes. Cloud computing ensures scalable infrastructure, while APIs facilitate seamless communication between different tax systems. Citizens experience streamlined tax filing, quicker refunds, and improved accessibility to tax-related information. Data encryption ensures the confidentiality of sensitive taxpayer data, instilling trust in the tax system. Open data initiatives can provide public access to certain tax-related information.

Digital Document Storage:

Digital document storage eliminates the need for physical paperwork, offering a more efficient and environmentally friendly solution. Cloud storage enables easy access to documents, promoting collaboration and reducing administrative burdens. Citizens can securely store and retrieve important documents, contributing to a paperless and accessible document management system. Encryption ensures the security of stored documents, protecting them from unauthorized access and maintaining the confidentiality and integrity of the information. Standardization ensures compatibility across systems.

Digital public infrastructure

Citizen’s Portals/Applications:

Citizen’s portals or applications serve as centralized hubs for citizens to interact with government services. It provides a user-friendly interface for accessing information, submitting applications, and conducting transactions. With robust user authentication methods, such as two-factor authentication, citizens can trust the security of their interactions, making government services more accessible and citizen-centric. APIs enable seamless integration with various government services, allowing citizens to access information and perform transactions from a single interface. Mobile networks (3G/4G/5G) enable access through applications and cybersecurity features protect user data. AI/ML algorithms can personalize user experiences based on preferences.

Technology Enablers:
