Digital Student ID for Costa Rica's TEC University

Costa Rica · Education · Digital Student ID · PoC

A project to build a digital identity system using OmniOne Open DID open-source software to issue mobile student IDs and connect them with university academic services.

Project Overview

The project aimed to develop a digital ID system for TEC (Instituto Tecnológico de Costa Rica), one of Costa Rica’s leading technical universities, enabling students to verify their identities and access academic services using mobile student IDs.

The project used OmniOne Open DID open-source software and W3C standards-based decentralized identifier (DID) and verifiable credential (VC) technology. It was conducted as a proof of concept (PoC) to assess the potential of digital identity technology in a university setting.

Background & Objectives

Korea's Ministry of the Interior and Safety and the National Information Society Agency (NIA) have supported official development assistance (ODA) projects that share Korea's experience in building digital government and DID services and help partner countries strengthen their digital government capabilities.

As part of this international cooperation, the Costa Rica project introduced digital student ID technology at a local university and sought to strengthen technical capabilities in digital identity and digital wallets.

Implementation & Architecture

The project used OmniOne Open DID open-source technology based on the K-DID Framework. Blockchain and DID/VC technology supported a system for issuing mobile student IDs and connecting the issued credentials with academic services.

The aim was to enable students to use university-issued digital identity credentials on their mobile devices and allow academic services to verify those credentials when needed.

How It Works

1Digital Student ID Issuance

University issues mobile student IDs
2Student ID Use

Students use credentials on mobile devices
3Academic Service Integration

University services verify digital identities

System Architecture Integrating Open DID

Digital ID architecture: Issuers (TEC, UCR, University) issue IDs and certificates through the Committee (Issuer System, Trust Agent, Verifier System, Wallet) to Service Providers (University, Shopping, Company)

Expected Outcomes

The PoC supports efforts by the Costa Rican government and universities to strengthen their capabilities in digital identity and digital wallets and assess the potential uses of mobile student IDs. By establishing a framework for issuing and verifying digital credentials in educational institutions, it is also expected to help identify opportunities to extend the approach to a wider range of university services.

Integrated Digital ID Services for Indonesia's Digital Government

Indonesia · Government · Digital ID · PoC

A project using OmniOne Digital ID to design an integrated digital identity authentication framework and demonstrate digital credential issuance, verification, and integration with public services.

Project Overview

To support the integration of Indonesia's government digital services, the project implemented a digital ID service model centered on the INAPas app, bringing together identity verification, digital credential issuance and verification, and access to a range of public services.

Using OmniOne Digital ID, the project designed a secure digital identity authentication framework based on X.509, W3C VC, single sign-on (SSO), and blockchain technology. The PoC and related consulting covered the issuance of digital health insurance and family relationship credentials, vaccination appointment booking, vaccination certificate issuance and verification, and access to vaccination status information for public health officials.

Background & Objectives

In 2023, the Indonesian government enacted a presidential regulation to accelerate digital transformation and integrate national digital services, identifying digital ID adoption as a key priority. This increased the need for an integrated digital identity authentication framework that could securely connect government services.

At the April 2024 cooperation committee meeting of the Korea-Indonesia Digital Government Cooperation Center, the two governments agreed to pursue an integrated digital ID services project and share Korea's implementation experience and technical expertise.

Implementation & Architecture

The project combined blockchain and DID/VC technology based on the K-DID Framework with the SaaS-based digital ID services provided by OmniOne Digital ID. It demonstrated an integrated service model in which users verify their identity through the INAPas app, receive digital credentials, and use them to access relevant public services.

The scope included integration with vaccination services to issue and verify vaccination certificates, as well as functionality that enables public health officials to view vaccination status information.

Key PoC Features

1Integrated Identity Verification

Digital identity verification via INAPas
2Digital Credentials

Health insurance and family relationship credentials
3Vaccination Certificate Issuance and Verification

Digital processing of vaccination certificates
4Public Service Integration

Vaccination booking and status information

Overview of Digital ID Structure

Digital ID structure: Issuers per institution, Owner (INApas) identity wallet, and Verifiers (INAku/INAgov), built on the INA Digital Platform and the Digital ID open source platform

Expected Outcomes

The project aims to strengthen the Indonesian government's capabilities in digital identity authentication services by sharing Korea's implementation experience and technology.

By presenting a model that connects authentication and credential use across public services through digital ID, the project is expected to serve as a reference for Indonesia's development of digital public infrastructure (DPI) for its citizens.

Cross-Border Academic Credential Verification between Japan and Korea

Japan · Education · Verifiable Credentials · PoC

A project applying digital student IDs and academic transcript VCs to university exchange programs between Japan and Korea to assess the feasibility of cross-border digital credential verification.

Project Overview

Japan's TOPPAN conducted a proof of concept (PoC) in collaboration with Soka University in Japan and Chung-Ang University in Korea to issue, submit, and verify digital academic credentials as part of the student exchange process.

The project aimed to assess VC interoperability between Japan and Korea by issuing student IDs and academic transcripts as verifiable credentials (VCs), submitting them across borders, and enabling the partner university in the other country to verify the submitted credentials. To support this process, a system for issuing and verifying VCs between the Japanese and Korean universities was built using OmniOne technology.

Background & Objectives

International student exchange programs require students to submit credentials issued by their home university to the host university, which verifies their identity and academic records.

The PoC applied VC technology to this process to assess whether universities in different countries could issue and verify digital academic credentials. Its scope covered both the verification of credentials issued in Japan by a university in Korea and the verification of credentials issued in Korea by a university in Japan.

Implementation & Architecture

Students received student ID VCs and academic transcript VCs from their home university and submitted them to the host university as part of their exchange application. The host university verified the submitted VCs to confirm the student's identity and academic records.

The same issuance, submission, and verification process was implemented in both Japan and Korea to test the feasibility of mutual verification of digital credentials across borders.

Japan–Korea VC Workflow

※ Note: VCs issued in Japan are verified in Korea. The same process applies when VCs issued in Korea are verified in Japan.

System Architecture Integrating Open DID

System architecture: Korea side (OmniOne Chain, Issuer, Trust Anchor, Verifier, Resolver, Wallet, Holder) and Japan side (OCSP Server, CA Server, Issuer, Verifier, Resolver, Wallet, Holder) exchanging VPs based on OID4VP

Expected Outcomes

Building on the knowledge gained and issues identified through the PoC, the project aims to establish an approach to VC interoperability between Japan and Korea by 2027.

Future plans include extending the model tested in education and student exchange to other cross-border services, including overseas employment, tourism, and global business. The goal is to enable secure verification of individuals' digital credentials across borders and contribute to the development of international digital identity systems.
