Touch Screen Input Interface with Concealment Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated banking machines lack secure and efficient methods for user input recognition on touch screens, particularly in environments where unauthorized access to input data is a concern.
Innovation Solution
The implementation of a touch screen display system that allows input recognition without visible output indicia, utilizing a processor to receive data from contact areas on the screen, and incorporating security features such as light emitting devices, mirrors, and concealment devices to prevent unauthorized viewing of user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen display shows visible output indicia for user input, then ease of operation is improved, but security against unauthorized viewing deteriorates
Solution Approach 1:
The display system is segmented into multiple independent components: a touch screen for input, light emitting devices for active area indication, and concealment devices for security. This allows each component to perform its specific function without compromising overall security or usability.
Solution Approach 2:
Light emitting devices are activated before user input to predefine and indicate the active input area. This preliminary action guides the user to the correct input location while the concealment device remains in place to prevent unauthorized viewing of the actual input data.
Solution Approach 3:
The light emitting devices serve as an intermediary between the user and the input system, providing visual guidance without revealing sensitive input data. The concealment device acts as another intermediary that blocks unauthorized viewing while allowing authorized users to interact with the system.
2Ease of operation
If a touch screen display provides visible feedback for user input, then ease of operation is improved, but reliability of secure transactions deteriorates
Solution Approach 1:
Visual feedback is provided locally through light emitting devices that illuminate only the specific active input area being used, rather than providing global visible feedback. This localized feedback maintains ease of operation for the current interaction while preserving security for the overall transaction process.
Solution Approach 2:
The display system dynamically adjusts its behavior based on the transaction state: light emitting devices activate to provide feedback during legitimate user interaction, while concealment devices remain active to prevent unauthorized viewing. This dynamic behavior ensures both usability and security are maintained throughout the transaction process.

Data Source
AI summary
An apparatus that operates to cause financial transfers responsive to data read from data bearing records includes at least one processor that is in operative connection with a card reader, a check acceptor, a cash dispenser and a touch screen display. The processor causes the machine to operate to read card data from a user card, and to cause a determination to be made that the read card data corresponds to an authorized financial account. The at least one processor is operative to cause data to be read from a check and/or cash to be dispensed, and a financial transfer to or from the account corresponding to the value thereof. Data corresponding to a user input alphanumeric characters is resolved by the processor responsive to contact with an input surface of the touch screen display. The area of contact may not include any visible output indicia that corresponds to the possible input characters prior to contact.
