Sedicii

Sedicii is an identity verification technology company that specializes in Zero-Knowledge Proof (ZKP)-based privacy-enhancing technologies. The company's platform enables organizations to verify claims about individuals — such as address, age, and identity — without exposing or transferring underlying personal data, addressing compliance requirements under GDPR and similar data protection regulations. Sedicii's core technology allows a relying party to confirm that a piece of data is true (e.g., a person lives at a claimed address, or is over a certain age) by querying authoritative data sources through a privacy-preserving cryptographic layer, rather than directly accessing or storing that personal information. This approach ensures that neither the verifying organization nor any intermediary receives raw personal data during the verification process. A key operational example is Sedicii's collaboration with ESB Networks (ESBN) in Ireland, where ESBN serves as the authoritative source for national address data. Using Sedicii's ZKP platform — approved by the Irish Data Protection Commissioner — third parties can validate customer address data against ESBN's records without ESBN exposing any underlying data externally. Sedicii also operates in the age verification (AV) space and is a member of the Age Verification Providers Association (AVPA), participating in ISO standards development for AV. The company's PHACKS initiative is a collaborative piloting program exploring functional verification requirements such as address verification, age verification, TCP/IP address verification, and location verification across industry and government sectors in Ireland and the EU. Target markets include regulated industries, government bodies, and any organization with KYC, AML, or age-gating obligations that must balance compliance with data minimization principles.
