Service User Identifier for Authentication Isolation

The patent introduces an authentication service as an intermediary between users and subscribing sites. The service holds personal data and verifies authentication credentials without exposing direct links between users and sites. The service acts as a mediator that validates credentials and returns verification results, thereby simplifying authentication while maintaining security through the intermediary layer.

The patent creates a universal authentication service that can be used across multiple subscribing organizations. Instead of requiring separate authentication devices for each organization, the service provides a single credential verification mechanism that works with all participating sites. Users authenticate through the service once, and the verification is accepted by multiple organizations, thereby providing broad authentication coverage while reducing the number of devices users must manage.

The patent inverts the conventional distribution model by not pre-assigning devices to users before distribution. Instead, devices are distributed first without binding them to specific users, and the authentication service establishes the device-user relationship dynamically during the authentication process. This reversal eliminates distribution delays and security risks associated with pre-assignment, while still ensuring reliable device-user relationships are established when needed.

The patent implements a self-service distribution model where authentication devices are bulk-shipped to organizations but are not pre-configured or pre-assigned. The authentication service automatically handles device registration, user association, and credential management without requiring administrative intervention. Organizations simply distribute the devices to users, and the service manages the rest, thereby maintaining high distribution efficiency while eliminating administrative burdens.
