Dynamic touch screen for automated teller machines (“ATMs”)

摘要

Systems and methods according to the present invention provide a more secure Automated Teller Machine (ATM) transaction by preventing observation of banking customers' Personal Identification Number (PIN). Such systems and methods make it difficult to obtain a customer's PIN by tracking the hand movement of a customer using an ATM. Inputs presented for a customer selection are preferably dynamically displayed in different locations preferably each time the customer is asked to enter a PIN. Dynamically changing the sequence of the display and/or location of the presented inputs reduces the possibility of mapping the hand movement of the customer to the positions of the inputs displayed for a customer selection. Inputs may also be presented at a very narrow viewing angle, thereby making observation of a PIN difficult. Hence, banking customers are preferably provided with a more robust and secured ATM transaction system.

主权项

1. A system for providing a more secure entry of four numeric inputs part of a confidential access sequence comprising:
an input/output device configured to display ten numeric inputs available for a user selection and to accept a user selection of the four numeric inputs; a machine readable memory configured to store machine executable instructions for displaying only the four numeric inputs part of a user's confidential access sequence in pre-determined, temporary positions and displaying at least five of the ten numeric inputs in conventional positions; and a processor device configured to execute the machine executable instructions for displaying only the four numeric inputs part of the user's confidential access sequence in pre-determined, temporary positions, displaying the at least five numeric inputs in conventional positions and communicate the pre-determined, temporary positions and the conventional positions to the input/output device;wherein the conventional positions comprise displaying the at least five numeric inputs in ascending order and dispersed among at least two rows, each row comprising positions for not more than three of the ten numeric inputs.
