Siireteid

Siireteid is a proposed digital identity standard intended for procurement networks to verify and authenticate participants in purchasing transactions. The term combines shiire, the Japanese word for procurement, with id, signaling its role as an identity credential for suppliers, buyers, and intermediaries. The core aim is to provide a stable, interoperable identity token that can be used across multiple procurement platforms, including enterprise resource planning systems, e-invoicing networks, and supplier portals.

Technically, siireteid relies on a lightweight public-key infrastructure. Each entity obtains a credential from a trusted issuer in a governance network, such as a certification authority or procurement regulator. The credential attests to attributes like entity_id, legal_name, role (supplier, buyer, broker), jurisdiction, and validity period. Tokens can be presented as compact verifiable credentials or embedded in standard data formats such as JWT-based statements. A central or federated registry maintains a list of trusted issuers and revocation status to support real-time verification.

In deployment, siireteid is typically governed by an industry consortium or standards body that designs the data model, security requirements, and interoperability guidelines. Implementations are intended to be platform-agnostic, enabling APIs, event streams, and plug-ins to connect ERP, procurement, and invoicing systems. Privacy controls govern what attributes are disclosed and when, with support for selective disclosure and consent management.

Adoption has been motivated by the need to reduce onboarding time, improve auditing, and minimize duplicate accounts across networks. Challenges include key management, cross-border trust, privacy considerations, and potential vendor lock-in. Critics argue that a central trust paradigm may introduce single points of failure, while supporters point to modular, revocable credentials as mitigations.
