WingArc1st and Cybertrust Collaborate to Build a Digital Trust Infrastructure for the AI Era

WingArc1st Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Jun Tanaka; hereinafter, WingArc) and Cybertrust Japan Co., Ltd. (Headquarters: Minato-ku, Tokyo; President & CEO: Yuji Kitamura; hereinafter, Cybertrust) have agreed to collaborate on promoting the domestic adoption of 'trust services,' represented by e-seals and digital signatures, and on building a digital trust infrastructure for the AI era.

Through this collaboration, they will technically guarantee the authenticity of various forms and documents generated in commercial transactions, preventing spoofing and tampering, thereby ensuring secure data distribution, which is a prerequisite for automated analysis and data processing by AI.

The two companies will achieve both legal reliability and operational efficiency in the complete paperless transformation of inter-company transactions. Through the construction of a trust infrastructure compliant with global standards, they will contribute to the realization of an advanced data-driven society suited for the AI era.

While the digitalization of inter-company transactions and DX are accelerating, business automation using AI technologies, including generative AI, is rapidly advancing. In an age where AI processes vast amounts of data at high speed and makes autonomous decisions, technically proving the authenticity of data and preventing spoofing and tampering has become an indispensable condition for the safe use of AI.

Furthermore, in March 2025, the Ministry of Internal Affairs and Communications established the 'Regulations Concerning the Accreditation of Certification Business for e-Seals,' and preparations are underway for the operation of an accreditation system for certificate authorities that issue e-seal certificates for secure data distribution.

Companies and organizations promoting DX are also required to take initiatives to ensure the authenticity of electronic forms, invoices, and certificates, and the use of trust services is expected to expand.

WingArc provides the 'Trustee Timestamp' service, a Ministry of Internal Affairs and Communications-certified timestamp service that proves the issuance and existence time of electronic documents, as well as a digital forms infrastructure, to ensure the reliability of electronic documents in inter-company transactions.

Cybertrust provides the 'iTrust Remote Signing Service' for long-term authenticity of electronic documents and the 'iTrust e-Seal Certificate,' issued only to rigorously vetted organizations.

As private companies responding to the e-seal accreditation system promoted by the Ministry of Internal Affairs and Communications, the two companies will link their respective technologies, knowledge, and services to promote the spread of a digital trust infrastructure that balances 'secure data handling' and 'advanced automation' in the AI era.
Specifically, they aim to develop a service that ensures the authenticity of digital forms by applying e-seals using certificates issued by Cybertrust to the digital forms generated from WingArc's forms infrastructure, thereby proving the origin and ensuring authenticity.

WingArc's digital forms infrastructure 'SVF' and digital trust-related products will be linked at the infrastructure level with Cybertrust's 'iTrust Remote Signing Service' and 'iTrust e-Seal Certificate' to promote the implementation and technical verification of trust service functions. The new service is scheduled to be launched by WingArc in the summer of 2026 as a foundation to support secure data distribution in the AI era.
