🇸🇬 Singapore devs: Add NRIC / FIN to the AI identity standard — Soulprint open source (30 min PR)

#opensource #ai #identity #webdev

Every day, AI agents make decisions on our behalf — buying, sending emails, signing documents — and nobody verifies there's a real human behind them.

Soulprint solves this with Zero-Knowledge Proofs: 100% on-device, open source (MIT), free to run. soulprint.digital

🇸🇬 Singapore's NRIC / FIN is not in Soulprint yet. You can add it in ~30 minutes with one PR.

What Soulprint does

npx soulprint verify-me       # scan ID + face match — all local
# → SPT token (score 0-100)

# AI agent includes token in every call
# X-Soulprint: eyJ... (score: 84)

# API verifies in 3 lines:
import { requireSoulprint } from "soulprint-mcp";
server.tool("premium", requireSoulprint({ minScore: 80 }), handler);

🇸🇬 Singapore: NRIC / FIN

NRIC: S (citizen born before 2000) or T (citizen born 2000+) + 7 digits + check letter. FIN: F or G prefix.

The code — fill in the blanks and open a PR

// packages/verify-local/src/document/countries/SG.ts
import { CountryVerifier, DocumentResult, NumberValidation } from "../verifier.interface";

const SG: CountryVerifier = {
  countryCode:   "SG",
  countryName:   "Singapore",
  documentTypes: ["nric", "fin"],

  parse(ocrText: string): DocumentResult {
    // NRIC / FIN format: S/T/F/G + 7 digits + letter
    const doc_number = ocrText.match(/([STFG]\d{7}[A-Z])/)?.[1] ?? "";
    return { valid: !!doc_number, doc_number, country: "SG" };
  },

  validate(docNumber: string): NumberValidation {
    // checksum via weighted mod-11 with letter map
    return { valid: validateNRIC(docNumber) };
  },
};

export default SG;

Then add one line in registry.ts:

import SG from "./countries/SG";
// add to registry map: "SG": SG,
