摘要

A method comprising: automatically providing, by a client device to a server, information regarding the identity of data components comprising a user model stored at the client device, wherein each of said data components is associated with an attribute of a user of the client device; automatically identifying, by said server, data components that are missing in said user model, based, at least in part, on a reference model stored at said server; automatically sending, by said server, to said client device, said identified missing data components; automatically updating, by said client device, said user model to include said identified missing data components; and automatically sending, by said client device, data contained in one or more of said data components in said updated user model, to enable a service provided by said server.
