摘要： Die vorliegende Erfindung ermöglicht eine geheime Übertragung von bildlichen Informationen von einem Sender zu einem Empfänger, indem der Lichtbrechungseffekt genutzt wird. Der Empfänger hat eine durchsichtige Folie mit darauf aufgebrachten kleinen Linsen oder Prismen. Der Sender stellt dem Empfänger ein Bild dar, das der Empfänger durch die Folie betrachtet. Der Blick des Empfängers wird durch die Lichtbrechung auf bestimmte Teile des vom Sender dargestellten Bildes gelenkt, während andere Teile des Bildes für den Empfänger ausgeblendet werden. Wer die Folie nicht hat, kann aus dem vom Sender dargestellten Bild nicht auf die bildliche Information schließen, die zum Auge des Empfängers gelangt.

摘要： The invention relates to a method and a device for the tap-proof and manipulation-proof transmission of messages between a server and the computer of a client, over a computer network, and for the decoding of encoded messages by clients. The method and the device can be especially used for encoding online accounts, especially for online banking. The device, described as a cryptocard, is preferably a flat appliance comprising photosensory elements on the rear side and a display on the front side. The device also contains a logic element/processor and an electronic memory containing codes. It is placed on the screen of the computer of the client, on which the following is displayed in image format: (1) an encoded message, (2) the number of the code required for the decoding, and (3) the co-ordinates of the actual position of the indicator symbol. This information received by the photosensors is decoded by the logic element/processor by means of the code, and the message is decoded and displayed in a clearly visible manner on the display. The indicator symbol on the screen is simulated on the display. By clicking buttons marked with characters on the cryptocard, a message can be transmitted from the client to the server. As the marking of the buttons by the characters is fixed previously at random by the server and transmitted in a tap-proof manner to the cryptocard, the transmission of the message from the client to the server is also tap-proof. The tap-proofness in both directions allows a protocol for online banking to be implemented, which renders the PIN tap-proof and prevents the falsification of transfers.

摘要翻译：本发明涉及一种通过计算机网络在服务器和客户机的计算机之间防止篡改传输消息并且用于由客户机解密加密消息的方法和装置。该方法和设备尤其可用于在线账户的加密，特别是用于在线银行业务。该装置在下文中被称为钥匙卡，其优选为背面具有光电传感器元件且正面具有显示器的扁平装置。此外，它还包含一个逻辑电路/处理器和一个带有按键的电子记忆。它被放置在客户机的计算机的屏幕上，显示在下面的图像格式：（1）一个编码消息;（2）用于解密密钥的必要的数，和（3）的指针符号的当前位置的坐标。由光电传感器接收的这些信息由逻辑电路/处理器使用密钥解码，并且消息在显示器上未加密显示并清晰可见。屏幕上模拟屏幕上的指针图标。通过点击钥匙卡上标有字符的按钮，相反，可以将消息从客户端传送到服务器。由于字符按钮的标记以前是由服务器随机确定的并且已经以无声的方式发送到了钥匙卡，所以从客户端到服务器的这个消息的传输也是不可闻的。两个方向上的非可听性允许网上银行协议使得PIN不可用，并且使得不可能传送失败。

摘要： 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.
