Abstract

The invention relates to a method for anti-tapping and manipulation encoding for online accounts, in particular for online banking, by means of visual cryptography. A first partial secret image is generated on a film by the server according to the method of visual cryptography. A second partial secret image is generated by the server with keypads with random characters and displayed on the screen of the client, the keypad being clickable with the mouse. In the next step, the film and the screen are superimposed by the client such that both partial secret images give the image with the clickable keypad with written characters. The client can now enter a sequence of n characters by n mouse clicks on the keypads with characters. The information about which keys the client has clicked in which sequence is then transmitted to the server and the inputted sequence of characters reconstructed in the server.
