Data transmitting method, involves inputting data to be transmitted to data processing device e.g. computer, using input mask that is decrypted by optical filter and transmitting data to data processing device e.g. server

摘要

The method involves generating an encrypted input mask by a data processing device (1) e.g. server, and transmitting the mask to another data processing device (2) e.g. computer. The encrypted input mask is displayed by the data processing device (2). The encrypted input mask is decrypted in such a manner that the mask is viewed through an optical filter having a decryption pattern. The data to be transmitted are input to the data processing device (2) using the input mask that is decrypted by the optical filter, and are transmitted to the data processing device (1). Independent claims are also included for the following: (1) an online banking method comprising a method for transmitting data from a data processing device to another data processing device (2) a system for transmitting data from a data processing device to another data processing device.
