Data processing devices e.g. personal computer, communicating method for bank institute, involves signaling declaration of intention to customer using output unit, where acknowledgement on intention is requested by data processing device

摘要

The method involves determining a declaration of intention together with an acknowledgement request having a code of a data processing device (4). The code of the data processing device is chosen such that coded information (36) of a device (22) is considered as an authentication when the coded information is decoded. The device (22) decodes the information with another code of the data processing device. The declaration of the intention is signaled to a customer using an output unit (28) of the device (22) and the acknowledgement of the intention is requested by the data processing device. An independent claim is also included for a device for data technically secured electronic communication between a data processing device of a customer and a data processing device of a computer center in a bank institute.
