<p>In a method for verifying the identity of a user of a first device (1) connected to a second device (2) through a data link (3), the user is provided with a user-specific password (8). The method comprises transmitting user-specific data from the first device (1) to the second device (2) and comparing at least part of the data with data on the second device (2). The password data size exceeds the amount of data that the data link (3) is capable of transferring within a pre-determined interval of time. The user-specific data transmitted from the first device (1) to the second device (2) comprises one or more subsections (9,10) of the user-specific password (8) provided to the user. A system comprising a first device (1) connected to a second device (2) through a data link (3) employs such a method. Computer programs allow programmable processing devices to function as the first(1) or second device (2). <IMAGE></p> |
