Computer apparatus 1-3 is provided which is arranged initially to show on a display 2 a request for the input of user identification data comprising an appended list of personal information such as a date of birth, postcode and an indication of gender. When identification data has been entered, the computer 1 utilizes the input ID either to retrieve records from a user record database 12 or alternatively processes the ID to extract the personal data encoded in the identification data which is utilized to extract records from an interest database 18. Thus information specific to a user may be retrieved or alternatively information may be targeted towards a user utilizing only the personal information encoded in the identification data without having to store that personal information as part of a user record. The ID may be used for data retrieval and/or targetting over the Internet (157, fig 11). |
