Seiko Solutions Launches 'e-seal' Digital Corporate Seal Infrastructure via eviDaemon

Seiko Solutions Inc. (President: Jun Sekine; Chiba, Japan) has announced the support for 'e-seals' in its document authenticity assurance services, 'eviDaemon for PAdES (Software Version)' and 'eviDaemon on Cloud (Web API Version).'

eviDaemon is a leading digital signature service in Japan. It enables the issuance of timestamps certified by the Minister of Internal Affairs and Communications and the secure storage of individual digital signatures compliant with international standards. It is widely used in systems for the Electronic Bookkeeping Law, medical records, and electronic contracts.

An 'e-seal' (Electronic Seal) is a mechanism that proves the 'issuer' and the 'absence of tampering' for electronic data (such as PDFs) issued by corporations or organizations. It serves as the digital equivalent of a corporate seal (square seal) to ensure the reliability of documents issued by an entity.

Key Features of e-seals in eviDaemon

1. **Integration-Ready Deployment** Designed for cross-functional use across entire business systems rather than being limited to specific applications. Existing eviDaemon users can use e-seals on the same platform, maintaining operational consistency. - **Software Version**: Can be implemented in on-premise or closed network environments. - **Web API Version**: Accessible from cloud services or SaaS via Web APIs.

2. **Long-Term Reliability through Certified Timestamps** Integration with Seiko Solutions' certified timestamps allows for: - Confirmation of existence at the time of issuance. - Verification of integrity throughout the storage period. - Operations focused on long-term storage and re-verification.

Expected Use Cases - Various certificates and notification documents. - Business forms such as estimates, invoices, delivery notes, and receipts. - IR materials, PR materials, and official announcements. - Document management systems complying with the Electronic Bookkeeping Law.

Seiko Solutions will continue to support the digital transformation of government agencies, financial institutions, and private enterprises by evolving its trust service infrastructure.
