VeriServe Collaborates on Ministry of Internal Affairs and Communications Adopted Project by Kansai Television Software, Demonstrating Safety Evaluation for Information Distribution in Internet-Challenged Environments

VeriServe Corporation (Headquarters: Chiyoda-ku, Tokyo; President & Representative Director: Tadahiro Shigehara; hereinafter VeriServe), a company providing services to support software quality improvement, collaborated with Kansai Television Software Co., Ltd. (Headquarters: Osaka, Osaka Prefecture; President & Representative Director: Takashi Hashimoto; hereinafter Kansai Television Software) on a demonstration project for a disaster information platform combining IPDC (IP Data Cast)*1 and blockchain technology. VeriServe conducted safety evaluations, comparative verification, and threat analysis from a third-party perspective, aiming to secure reliability for societal implementation.

This initiative is part of a demonstration project*2 by the Ministry of Internal Affairs and Communications, aiming to realize a new information infrastructure that enables the continuation of administrative procedures and economic activities even in situations where internet connection is difficult.

*1 A broadcasting service that divides data into IP packet format and simultaneously distributes information over broadcast waves.

*2 Development and Demonstration Project for Countermeasures Against Fake/Misinformation on the Internet (FY2025).

Overall picture of disaster information distribution and verification combining IPDC and blockchain.

■ Background

In recent years, the disruption of communication infrastructure during disasters has been recognized as an issue affecting not only the transmission of evacuation information but also the entire social function, leading to the stagnation of administrative procedures and economic activities. To address this situation, the importance of mechanisms that can distribute information without relying on communication networks is increasing.

Kansai Television Software is working on building an information distribution platform that functions even during disasters by combining IPDC, which distributes data simultaneously using broadcast waves, with blockchain technology, which verifies the authenticity of information.

■ VeriServe's Role (Ensuring Reliability through Third-Party Verification)

In this demonstration, VeriServe evaluated the safety and reliability of the system from a third-party perspective.

【Key Evaluation Items in this Demonstration】

- Comparative verification of IPDC + Blockchain method, PKI method, and DID/VC method.
- Risk assessment based on system configuration (threat analysis).
- Security evaluation assuming numerous attack scenarios.
- Problem extraction and improvement proposals with an eye towards societal implementation.

Technical feasibility and safe operation are separate challenges. Especially for highly public information infrastructures, ensuring reliability through objective third-party verification is indispensable. VeriServe leveraged its accumulated knowledge in software quality and cybersecurity to support reliability assurance in this project.

Further details are introduced in a case study article on VeriServe's website. Please refer to:

■ Verification Results

Through this verification, the effectiveness of the method combining IPDC and blockchain was confirmed from the perspective of a disaster information distribution platform. Additionally, an evaluation was conducted regarding the assurance of information authenticity in offline environments, confirming its effectiveness and clarifying challenges and considerations for practical operation.

Furthermore, potential risks were visualized through threat analysis, and directions for future security measures towards societal implementation were presented.

■ Social Significance

This initiative is an important step towards realizing a new infrastructure for delivering reliable information even during disasters.

In particular, by combining information distribution independent of communication environments with mechanisms to ensure information authenticity, it is expected to contribute to solving conventional information distribution challenges.

In the societal implementation of such new technologies, ensuring reliability through third-party verification is essential, and VeriServe is contributing to improved social acceptance by playing that role.

■ Future Outlook

Moving forward, discussions for societal implementation will proceed based on the knowledge gained from this demonstration. VeriServe will continue to support the advancement of technology and reliability assurance from a security and quality perspective, contributing to the realization of highly public information infrastructures.
