Abstract: A computer apparatus and a method is described for establishing a global interest profile of a user. At least one local server and an enterprise server communicate with the user via a communication channel. The local server assigns a local ID to the user. The enterprise server assigns to the user a global ID and links the local ID and local user information with the global ID to form a global interest profile of the user. The identity of the users is not shared between servers, thereby maintaining the privacy of the user.
