System and a method for selective data retrieval from a remote database on basis of caller line identification and user specific access codes

摘要

The present invention relates to a system and a method for retrieving information from a database (7). The object of the invention is to utilise both the information automatically transmitted at the point when the telecommunication connection is established and a code, relating to safe identification, for reliably identifying a subscriber A and for retrieving information from a correct location in the database. For this purpose, the system includes a subscriber device (1A, 1B) of the subscriber A for establishing a telecommunication connection and for managing communication during it, a data processing system (2) of a subscriber B for responding to a request for contact of the subscriber device (1A, 1B) of the subscriber A, the data processing system (2) containing the database (7) or being in contact with it, and the data processing system (2) further comprising a system for receiving an identifier (3) of the subscriber A, a system for receiving a predetermined code (4) from the subscriber A, and a system for retrieving information from the database (7) on the basis of the identifier (3) and the code (4) of the subscriber A.
