# ToughID

> Cryptographic identity attestation without stored personal data. Identity is verified once by a trusted provider, resulting in a signed cryptographic token bound to a public key. Systems verify the signature, not the underlying data. No personal data database. No honeypot.

## The Identity Honeypot Problem

Most identity systems centralise personal data so that relying parties can verify it. The result is a database that becomes a permanent target. Breach of one identity provider exposes millions of identities.

## How ToughID Works

1. A trusted issuer verifies an identity once — KYC, eIDAS, EUDI, or equivalent.
2. The issuer produces a signed cryptographic token bound to a public key controlled by the user.
3. Relying parties verify the signature against the issuer's public key. They never receive the underlying personal data.
4. Selective disclosure: the user can prove specific attributes (age over 18, jurisdiction of residence, regulatory status) without revealing the full identity record.

## Properties

- No central database of personal data
- Compatible with EUDI and eIDAS frameworks
- Selective disclosure as a first-class operation
- Phantom Secrets™ integration for the user's signing key — the key proves identity without ever existing at rest
