1. A method for recognizing and/or identifying a user with a chip in an electronic identity object storing a digital identity,
the method comprising steps of:
establishing a wireless or electrical connection between the electronic identity object and a verification terminal;
verifying, in the electronic identity object, if the verification terminal is authorized to communicate with the electronic identity object, and in response of a positive verification sharing a secret:
using the shared secret for establishing an encrypted symmetric data link between the electronic identity object and the verification terminal;
transmitting, through the encrypted data link, said digital identity stored in the electronic identity object to the verification terminal; and
verifying in the verification terminal the authenticity of said digital identity,
acquiring, in the verification terminal, a biometric template of the user; and
verifying in the verification terminal if the acquired biometric template matches a biometric template stored in the electronic identity object, and
encrypting, in the electronic identity object, the biometric template using a homomorphic encryption so as to generate a homomorphically encrypted biometric template.
