Passport-backed LinkedIn identity verification to stop emailed ID leaks

Many talent teams, staffing agencies and hiring managers routinely ask candidates to email passport or government ID images, creating a concentrated leak risk and exposure to identity fraud and compliance fines; this is a practical problem across an addressable market of roughly 3,000,000 organizations that spend about $4,000 ACV on identity verification services (a $12.0B global market). The failure mode is both operational — unencrypted attachments in ATS and email — and trust-related, since recruiters cannot reliably bind a presented document to an online professional profile. You could build a passport-backed LinkedIn identity verification service that performs passport scans, biometric liveness and document-forgery checks, then issues a cryptographically verifiable attestation (W3C Verifiable Credential / signed token) directly tied to a LinkedIn profile and accessible to recruiters without exchanging raw ID images. Integrations would include an in-message LinkedIn flow and ATS connectors so companies receive a verification flag and an audit trail rather than scanned documents, and users retain a revocable credential instead of sending copies. Commercially this maps to existing buyer economics — per-organization SaaS with per-verify credits — targeting the $4,000 ACV segment while monetizing volume. The timing is favorable: remote hiring growth and enterprise interest in decentralized, auditable credentials, combined with improved AI document and face-match accuracy, reduce per-verify costs and increase buyer willingness to pay into the $12B market. Differentiation will come from a frictionless LinkedIn-native UX and strong cryptographic attestations that materially reduce emailed-ID leaks, but you must be candid about hurdles — obtaining LinkedIn cooperation, meeting GDPR and local ID law requirements, winning user trust to upload passports, and staying ahead of forgery techniques.
