US Patent 7895445 Token-based remote data access

Data transfer between remote and home locations over a network is effected using an electronic token to facilitate access to the data. According to an example embodiment of the present invention, a network-based server facilitates the generation of a token specifying conditions upon which data access to a registered user's data can be made. When a request for data transfer is received in connection with a token, information in the token is used together with the request to selectively authenticate and serve the request.
