Telefónica, a Spanish telecommunications giant, has now become a system integrator for Polygon's identity solution Privado ID. Telefónica Tech, Telefónica's digital business unit, will integrate Privado ID's tools into its managed blockchain service, TrustOS, according to a September 10 announcement. The collaboration aims to develop proof-of-concept for a variety of digital identity use cases, including age verification, digital national identity, e-signature solutions and content authentication. It comes as Europe prepares to implement the European Digital Identity Regulation, a framework proposed by the European Union to provide citizens, residents and businesses with digital, universally recognised digital identities for accessing public services and conducting transactions.
