eIDAS for Proof of Personhood viability

1

Hello,

With the rollout of eIDAS 2.0 and the broader adoption of EU Digital Identity Wallets, there may be an opportunity to leverage government-backed digital identity systems.

I am particularly interested in whether eIDAS electronic signatures, whether generated through eIDAS-compliant national ID smartcards or additionally, if viable, through national Digital Identity providers, could be used for DIM2.

Would integrating eIDAS RSA-SHA256 signatures into DIM2 be feasible?

The biggest question is how will you protect them from being compromised?

@prodigalwon By who? By the government?

If we can accept key keeping authorities (contradicts R3 in Gav’s requirements) the question remains if the final standards will provide contextual pseudonymity (req. R5: “privacy”: sticky pseudonym per service for uniqueness but unlinkability of presentations to different services for privacy). AFAIU, it is too early to know.

What the Demo app provides is certainly not viable for anonymous PoP as the goal of these signatures is to be able to verify the signer’s identity.

Yes. Corrupt governments should not be able to compromise our system.

With Eidas v2, UE forced member state to provide for the end of 2026 a wallet for their citizen to both prove their identity and put their administrative documents in it, the aim was administrative cross border compatibility.

Problem is, the format of the wallet wasn’t specified in Eidas, and member state choose a web2 solution instead of the DID (Decentralized IDentifier, a P256 pair of key). It will be the PID, containing identity with a crypto chain of trust from the member state.

A compromise is currently being build between UE and member state, centralized solution for proof of identity, and at the regional level decentralization for coordination.

The UE administrative blockchain is live since a few week and a consortium as been created, the Europeum Edic , to deploy software on this infra.

I’m a little implicated in it and interested about how blockchain can be use to create new form of (smart) social contract.
