Beyond the internal seal, the passport carries a public-key signature (Ed25519). Anyone can independently verify —without trusting DPP Fácil— that this data was issued by the key holder.

What does this mean? The seal is a cryptographic signature (HMAC-SHA256) computed over the passport's official data with DPP Fácil's key. It confirms this passport is authentic and its data has not been tampered with. It does not use blockchain: it is a verifiable digital signature, at no cost or complexity for the brand, and ready for the European DPP registry once it comes into force.
