15 Claims

1. A computer-implemented method for use in implementing a common domain for user recognition in a browser, the method comprising:

receiving, by a computing device, a recognition token associated with a profile;

setting, by the computing device, via a browser accessing a common domain, a cookie in the browser, the cookie including the recognition token;

in response to a request for a service, via a user, through the browser accessing an entity domain associated with an entity, accessing, by the computing device, the common domain;

accessing, by the computing device, via the browser accessing the common domain, the cookie and submitting the cookie to a common domain server;

receiving, from the common domain server, a federated ID token associated with the recognition token for the service; and

retrieving, by the computing device, via the browser, the profile associated with the user based on the federated ID token, thereby permitting the computing device to initiate an interaction with the entity, via the browser accessing the entity domain, based on a credential included in the profile.
