Method for providing an international infrastructure for trusted universal identification over the Internet by using existing resources. Each participating country sets up a national database and server system and imports data from local, official ID data sources which are normally indexed by a unique identifier. Attaching the home country's ISO-3166 code to this identifier, a worldwide unique identifier results ("universal ID" or "uID"). The binding of a group code to uID widens scope to identify other entities. Each country connects its database to the Internet and acts as an authentication and authorization broker to worldwide uID holders. A user, to access securely any uID compliant service on the Internet, may use his/her uID in conjunction with a password or biometric data. It may be used in international, security sensitive areas to produce trusted identity and to securely submit personal details without the burden of filling in forms.
