Abstract: An authentication mechanism for use in network-based services generates an authentication token. The authentication token is provided to a client device as part of the code comprising a content page. The content page code is received and loaded by a browser application at the client device. When the content page code is received and loaded by the browser application, the authentication token is loaded by the browser as well. Upon receiving subsequent input, the browser application may send a content request to the server. The content request includes the authentication token maintained by the browser application in the content page. A server may validate the authentication token provided in the request using version information and one or more master authentication tokens.

Abstract: A system and method for independently determining the geographical location of a user accessing a networked system. The method may include gathering a plurality of inputs about the user's geographic location; weighting each input based on whether said input identifies a likelihood of true geographic location; determining whether each input verifies a geographic location specified by the user; and summing weights of the input factors verifying the specified geographic location. A system for independently determining the geographical location of a user includes a user login routine, a heuristic user geographic location determination engine, and at least one data store including a user profile record having a user specified geographic location.
