ZenmuTech Inc. (hereinafter "ZenmuTech," Headquarters: Chuo-ku, Tokyo, Representative Director: Yasuhisa Abe), which pursues data protection and utilization through "secret sharing technology" that divides and disperses information in a meaningless form, announced that its core secret sharing technology has been adopted as a co-developed "Secret Sharing Proxy" (patent pending) in the medical DX platform "Digital Trust Grid" developed by AIHOBS Inc. (hereinafter "AIHOBS," Headquarters: Minato-ku, Tokyo, Representative Director: Yasuhide Hatta).
AIHOBS is a business company established to implement the research and development results accumulated by the "Healthcare AI Platform Technology Research Association (HAIP)" which emerged from the Cabinet Office's SIP (Strategic Innovation Program) Phase 2. It aims to build an industry-common platform connecting medical institutions and service providers, promoting its business in collaboration with co-creation partners including HAIP.
By implementing secret sharing technology in the proxy function of AIHOBS's multi-functional gateway (GW), it realizes both advanced data confidentiality and convenience in the medical field as a core technology of the zero-trust integrated platform.
This adoption marks an important milestone for the full-scale implementation of secret sharing technology into a practical operational network infrastructure in the medical field.
■ Background: Expanding Medical DX Market and Structural Security Challenges
The medical DX market is expected to expand due to factors such as the advancement of electronic medical records, the spread of telemedicine, the progress of AI diagnostic support, and the cloud integration of medical data. The standardization and sharing of medical information are also being promoted politically, making the development of a secure data distribution infrastructure a societal imperative.
On the other hand, medical institutions are targets of ransomware attacks, and disruptions in medical care or information leaks are extremely serious issues with significant social impact. Traditional security relying on encryption key management has structural limitations, such as the risk of decryption upon key leakage and increased operational burden.
■ Co-developed "Secret Sharing Proxy"
ZenmuTech's secret sharing technology is a next-generation security technology that adopts a mechanism to divide data into multiple meaningless fragments, which cannot be restored unless all fragments are present.
The "Secret Sharing Proxy" co-developed with AIHOBS implements this technology at the network layer, structurally protecting the medical data distribution path itself.
- Complete Meaningless Data
- Each dispersed fragment has no meaning on its own and cannot be deciphered as information even if stolen.
- Escape from Key Management Dependence
- Transforms the very form of information existence, rather than merely improving encryption strength.
- Elimination of Single Point of Failure
- Distributed management structure reduces the risk of information leakage due to a single compromise.
- Implementation into Zero-Trust Integrated Platform
- Achieves a shift from "protecting" security to "meaningless even if stolen" security.
■ Significance in Medical DX Platform
With the integration of AIHOBS's safe and secure network and the Secret Sharing Proxy, the following become possible:
- Secure utilization of medical AI
- Secure data linkage between medical institutions
- Operational efficiency not dependent on physical separation
- Secure utilization of real-world data
■ Establishing Position in a Growing Market
ZenmuTech aims to establish secret sharing technology as a standard architecture in high-security fields. Its adoption as a core technology for the zero-trust integrated platform marks an important step indicating the full-scale social implementation of next-generation security.
Starting with full-scale implementation in the medical field, ZenmuTech will continue to promote technological innovation that supports the safe foundation of data-driven societies in areas such as:
- Public/administrative data infrastructure
- Smart city concepts
- Industrial IoT data protection
- AI learning data infrastructure
【ZenmuTech's Secret Sharing Technology】
Secret sharing technology is an information security method that divides important data into "multiple fragments that are meaningless on their own (= shares)" and manages/stores them separately, allowing the original data to be restored only when the authorized combination of shares is assembled.
