Abstract: A method for accessing private data/services from a mobile station over a public network is described including: composing a text-based request message on the mobile station, sending the request message to a private server offering access to private data/services, and checking the authenticity of the user based on the request message received by the server. If user authenticity is confirmed, a text-based response message is composed and sent to the mobile station. The request message includes a user-unique identifier received by the private server with an appended user mobile station number. Authenticity checking (by the private server) includes checking whether (1) the user-unique identifier is stored in a private directory database, and (2) the appended user mobile station number matches the number allocated to the user-unique identifier stored in the private directory database. The interaction is limited to the exchange of pairs of text-based request message(s) and response(s).
