Abstract

A computer (BAR) or computer system transfers useful data (U1 to Un) and also check data (V1 to Vn) derived therefrom to a data sink (R1, R2). The data sink checks the received useful data using the transmitted check data and also check data extracted by it from the useful data. At specific pre-defined or event-controlled time intervals, the data sink forms a sum check datum (W1.1, W1.2) from all the check data (V1.1 to Vn.1, V1.2 to Vn.2) received in the meantime and transfers this to the data source (BAR). It is compared there with a sum check datum (W1) formed according to the same principles from the check data (V1.1 to V1.n) inserted in the previously transmitted useful data. The use of the method according to the invention requires very little time for the return transmission of check data and therefore imposes a minimal load on the transmission system overall. <IMAGE>
