Problem Statement

Students, universities, examination boards, and employers need to access academic transcripts of students applying to higher education, work, or when transferring from one university to another. Such documents can be easily stored and shared online. However, there is a problem of verification of authenticity, enabling privacy-preserving access, as well as prevention of fraudulent or double use of transcripts in such sharing of PDFs, etc online.

Consider an example. After completing a 4-year degree program, a student graduates from a university and receives a degree and academic transcript showing his/her performance. The student is now the legitimate owner of these documents. However, this ownership comes with a clause of immutability— in that, the student cannot unilaterally change the contents of the certificate and transcripts. The university is empowered to alter these documents as the issuer of them (in some cases, even rescind certificates issued to students). However, the university is not the owner of these documents and cannot consent to these documents being used by some third party without the knowledge and consent of the student. Similarly, an employer who is using these documents to grant employment to the student, may have a clause that these same documents may not be used for gaining an alternate employment, while the current one is active. The employer may sometimes need to further share these documents with potential clients and/or regulators, however, this cannot be done without the knowledge or informed consent of the owner of these documents. 

A DPI architecture needs to provide sufficient underlying mechanisms where such nuances of ownership and entitlement such as the above, can be supported reliably. Privileges, obligations and liabilities should be made known to each stakeholder separately, and enforced by the architecture. Such an architecture should ideally be decentralized in nature, and should not empower just one entity to enforce these semantics, making this one entity the single point of failure and compromise. 

We invite you to design a solution using building blocks of the DPI architecture for managing, verifying, and sharing academic transcripts of students with other universities, companies, examination boards, etc. This solution should enable exam boards or universities to make available academic transcripts which students can share with other universities or companies at the time of applying for higher studies or employment. The solution should prevent fraudulent use as well as double use of documents, e.g. if a student has secured admission in a university, the student cannot, while holding on to the seat, apply to another university for an equivalent degree course.

Authors of the selected posters will have an opportunity to present their ideas on the day of the workshop.

More information on Digital Public Infrastructures:

Digital Public Infrastructures or DPIs enable countries, communities and businesses to achieve societal outcomes at scale using open and interoperable technologies to promote innovation and inclusion. It employs the following architectural principles to achieve this development:

DPI Tech Architecture Principles:

Interoperability –  To prevent information/data silos, monopolization, and walled gardens with the help of published protocols & standards/specifications for the ecosystem to adopt and comply with.

Minimalist & Reusable Building Blocks – A full solution approach assumes just one solution fits all  but a DPI approach uses minimalist components that perform one function well to catalyze combinatorial innovation and user-centric solution.

Diverse, Inclusive Innovation – Promote inclusion through the use of open APIs and other standards.

Federated & Decentralized by Design – Avoid centralisation to prevent over-aggregation of information by using solutions like wrapper apis across disparate systems.

Security & Privacy by Design – Build a ‘Trust no one architecture’ that operates on optimal ignorance – each system should know as little as possible.

Please refer to this website to familiarize yourself with DPI thinking and how you can build your own DPIs.

Talk and Speaker Details

  1. Title: DPI and the Four Internets

Abstract: One of the fundamental challenges in DPI design is to resolve issues of ownership. No technological solutions are possible until we have a sound understanding of what ownership entails. In this talk, we will look into how the term ownership is interpreted in different contexts and their implications on public infrastructure design. When it comes to the Internet itself, there are at least four different ways in which ownership of the information space, are addressed. This is exemplified by the “Four Internets” model proposed by O’hara and Hall. In this talk, we will also address the Four Internets paradigm and its implications on DPI design.

3. Title: Digital Twin for City-Scale Mobility Management and Planning

Abstract: Urban mobility has become a major challenge in many Indian cities. Bangalore has been ranked the most congested city in India in terms of traffic for several years in a row. Digital twins can provide a way to improve urban mobility by enabling what-if analyses (e.g. making a street “one way”) and by helping city planners to make better infrastructure decisions (such as adding a new metro line). However, digital twins require city-scale traffic models which are based on a good understanding of the mobility patterns and mode choices of the citizens. Recent advances in AI indicate that with sufficient sensor data about traffic volumes, speeds and other information about the road network, it is possible to build city-scale mobility models to achieve congestion mitigation and transport optimization. Such AI-driven digital twin models leverage computer vision, graph neural networks, transformers and agent-based simulations. This talk presents an overview of a digital twin solution for urban mobility based on the IUDX (India Urban Data Exchange) platform. IUDX is a MoHUA sponsored project as part of the Smarter Cities Initiative of the Government of India. The talk also describes our initial efforts in building a traffic model for Bangalore in collaboration with the Bangalore Traffic Police.

4. Title: Practical Privacy-Preserving Identity Verification using Third-Party Cloud Services and FHE

Abstract: National digital identity verification systems have played a critical role in the effective distribution of goods and services, particularly, in developing countries. Due to the cost involved in deploying and maintaining such systems, combined with the lack of in-house technical expertise, governments seek to outsource this service to third-party cloud service providers to the extent possible. This leads to increased concerns regarding the privacy of users’ personal data. In this work, we propose a practical privacy-preserving digital identity verification protocol where the third-party cloud services process the identity data encrypted using a (single-key) Fully Homomorphic Encryption (FHE) scheme. Though the role of a trusted entity such as government is not completely eliminated, our protocol significantly reduces the computation load on such parties. We implement our protocol using the Microsoft SEAL FHE library and demonstrate that secure demographic and biometric matching queries and age comparisons can be efficiently performed on batched FHE ciphertexts.

Speaker Bio: Dr. Srinivas Vivek is currently the Infosys Foundation Career Development chair professor at IIIT Bangalore. Previously, he was a postdoctoral researcher in the Cryptography group at the University of Bristol.

5. Title: Driving the Digital Public Infrastructure Growth Story with Data Exchanges

Abstract: India has witnessed an unprecedented digital revolution through the ‘India Stack’ that is unlocking the economic primitives of identity and payments at population scale through AADHAR and UPI. The third and final piece of the stack is establishing a new governance model through easy access and exchange of data. 

The real power of data is realized when there is seamless flow of data from the data provider to the data consumers and the data silos are broken. How the data is managed, exchanged and used is crucial to successfully resolving complex problems in domains such as agriculture, urban, geospatial and healthcare etc. A data exchanges is a platform which acts as an enabler to solve these problems and build innovative solutions. When developed for public good, the data exchange platforms are ideally open source, based on standardized data models and have robust security, privacy and accounting mechanisms that facilitates their easy adoption across the digital ecosystem.

This talk will focus on the idea of Digital Public Infrastructures and Data Exchanges in particular and how they are a critical tool for Digital transformation of a society. I will discuss the benefits of seamless flow of data from the providers and the consumers with some use cases and how business cases could be developed around these.

7. Title: Managing privacy in digital applications for public health

Abstract: DPIs provide an efficient path to rolling out robust citizen-centric applications at scale. Ensuring privacy of personal data for such applications is a key requirement, and this often requires domain and region-specific approaches. Public health applications can benefit from the services and capabilities of DPI and similar platforms, especially mechanisms for data protection and consent management. However, deploying applications that ensure privacy of health data across a variety of healthcare settings and demographics poses a number of challenges. In this talk, we explore some of these challenges, and discuss approaches for managing privacy that can be enabled by digital platforms, as well as limitations to such approaches.

8. Title: Building an Inclusive ID Systems

Abstract: In today’s digitally connected world Identity is one of the key factors that the environment consumes to make decisions.  From our social media handles to email addresses our identities are multiple and they differ based on the context. With Identity at the centre of this revolution, governments across the globe are attempting to leapfrog into the digital age. Governments are looking for a faster and more efficient way to deliver service to their citizens & residents. Foundational identity is one of the easiest yet most effective ways to achieve this goal. While this explosion is good, it has also created a digital entry barrier for many. This barrier is a curse when it comes to digital governance and service delivery across the world. We will discuss several ideas and strategies adopted by the open-source project – MOSIP to achieve the goal.

We will explore what goes into building, designing and securing inclusive digital Identities across multiple cultures.
