National digital identity systems

Many nations have implemented, are implementing, or have proposed nationwide digital identity systems.

Although many facets of digital identity are universal owing in part to the ubiquity of the Internet, some regional variations exist due to specific laws, practices and government services that are in place. For example, digital identy can use services that validate driving licences, passports and other physical documents online to help improve the quality of a digital identity. Also, strict policies against money laundering mean that some services, such as money transfers need a stricter level of validation of digital identity.

Digital identity in the national sense can mean a combination of single sign on, and/or validation of assertions by trusted authorities (generally the government).
