Privacy-preserving supplier risk map with coarse disclosure tiers
A supply-chain risk map emits coarse public risk tiers while keeping supplier contracts, volumes, and names in a private workspace.
Enabling disclosure
The method ingests supplier documents, audit notes, sanctions checks, incident records, and country risk data into a private assessment workspace.
Each supplier receives private factor scores. Before any public output is produced, the system aggregates suppliers into sector and geography bands that satisfy a minimum cohort size.
The public record contains a tier, evidence category, and time window. It does not contain supplier names, exact volumes, contract values, or uniquely identifying incidents.
This allows a technical approach to risk-tier publication to be defensively disclosed without leaking the confidential procurement data used by an organization.
Enablement checklist
- Normalizes supplier evidence into private weighted factors.
- Maps private scores into coarse public tiers with k-anonymity thresholds.
- Publishes only tier, sector, geography band, and evidence category.
Claims this blocks
- Public risk-tier publication derived from private supplier facts with k-anonymity.
- Separating supplier identity from published sector-level risk disclosures.
- Using disclosure tiers as public prior art while retaining confidential contracts.
