Kansai Telecasting Software Co., Ltd. Collaborates on Ministry of Internal Affairs and Communications Adopted Project, Demonstrating Safety Evaluation of Information Distribution in Internet-Challenged Environments

VeriServe Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Tadahiro Shigihara; hereinafter "VeriServe"), which provides services to support software quality improvement, collaborated with Kansai Telecasting Software Co., Ltd. (Headquarters: Osaka, Osaka Prefecture; Representative Director and President: Takashi Hashimoto; hereinafter "Kansai Telecasting Software") on a project adopted by the Ministry of Internal Affairs and Communications. In the demonstration of a disaster information infrastructure combining IPDC (IP Data Cast)*1 and blockchain technology, VeriServe conducted safety evaluations, comparative verifications, and threat analyses from a third-party perspective, focusing on ensuring reliability with a view towards social 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 transmits information simultaneously via 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, such as the stagnation of administrative procedures and economic activities. To address such situations, the importance of a mechanism that can distribute information without relying on communication networks is increasing.

Kansai Telecasting Software is working on building an information distribution infrastructure that functions even during disasters by combining IPDC, which distributes data simultaneously using broadcast waves, and 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 (threat analysis) based on system configuration

Security evaluation assuming numerous attack scenarios

Identification of challenges and proposals for improvement with a view towards social implementation

Technical feasibility and safe operation are separate issues. Especially for public information infrastructure, ensuring reliability through objective verification by a third party is indispensable. VeriServe utilized its accumulated knowledge in software quality and cybersecurity to support the assurance of reliability in this project.

Details are also introduced in VeriServe's case study article. Please refer to it.

Verification Results

Through this verification, the effectiveness of the method combining IPDC and blockchain was confirmed from the perspective of a disaster information distribution infrastructure. In addition, an evaluation was conducted from the perspective of ensuring information authenticity in an offline environment, confirming its effectiveness and clarifying challenges and points of attention for practical operation.

Furthermore, threat analysis visualized anticipated risks and presented directions for security measures towards future social implementation.

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 a mechanism to ensure information authenticity, it is expected to contribute to solving conventional information distribution challenges.

In the social implementation of such new technologies, ensuring reliability through third-party verification is indispensable, and VeriServe is contributing to improving social acceptance by fulfilling that role.

Future Outlook

Moving forward, discussions for social implementation will proceed based on the knowledge gained from the demonstration. VeriServe will continue to support the advancement of technology and the assurance of reliability from the perspectives of security and quality, contributing to the realization of public information infrastructure.
