A proposal for using a cryptographic national identity card in social networks

Abstract

The distinctive security features of the Spanish electronic national identity card allow us to propose the usage of this cryptographic smart card in an authentication framework that can be used during the registration and login phases of certain internet services, including popular social networks. Using this mechanism with NFC-capable devices, the identity and age of the potential user can be determined, allowing or denying the access to the service based on that information.
