πŸ‡ΈπŸ‡ͺ Sverige devs: Add Personnummer to the AI identity standard β€” Soulprint open source (30 min PR)

Every day, AI agents make decisions on our behalf β€” buying, sending emails, signing documents β€” 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

πŸ‡ΈπŸ‡ͺ Sverige's Personnummer 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 β€” all local
# β†’ 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);
Enter fullscreen mode Exit fullscreen mode

ZK proof: Circom 2.1.8 Β· Groth16 Β· 844 constraints Β· 564ms prove Β· 25ms verify.


πŸ‡ΈπŸ‡ͺ Sverige: Personnummer

Personnummer: YYYYMMDD-XXXX (12 chars) or YYMMDD-XXXX (10 chars). Last digit = Luhn check.


The code β€” fill in the blanks and open a PR

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

const SE: CountryVerifier = {
  countryCode:   "SE",
  countryName:   "Sverige",
  documentTypes: ["personnummer"],

  parse(ocrText: string): DocumentResult {
    // Personnummer format: YYYYMMDD-XXXX or YYMMDD-XXXX
    const doc_number = ocrText.match(/(\d{6,8}-?\d{4})/)?.[1] ?? "";
    return { valid: !!doc_number, doc_number, country: "SE" };
  },

  validate(docNumber: string): NumberValidation {
    // Luhn algorithm on 10-digit form
    return { valid: luhnPersonnummer(docNumber) };
  },
};

export default SE;
Enter fullscreen mode Exit fullscreen mode

Then add one line in registry.ts:

import SE from "./countries/SE";
// add to registry map: "SE": SE,
Enter fullscreen mode Exit fullscreen mode
