Orientation-Controlled Contactless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contactless communication technologies, such as those used in electronic entities like microcircuit cards, can inadvertently transmit confidential data without the user's knowledge, posing a security risk.
Innovation Solution
Incorporating a position sensor, like an inclinometer or gyroscope, to control data transmission by prohibiting communication if the electronic entity is not in an authorized orientation, ensuring data exchange only occurs when the device is positioned correctly, thereby preventing unauthorized data access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless communication is enabled for automatic data transmission, then communication convenience is improved, but security deteriorates due to involuntary data transmission
Solution Approach 1:
The patent changes the operational parameters of the contactless communication system by introducing orientation-dependent data transmission. The system monitors the orientation parameter through a sensor and only transmits data when the orientation matches the predetermined authorized orientation, thereby maintaining communication convenience while preventing unauthorized data access
Solution Approach 2:
The patent introduces an intermediary control mechanism (orientation verification system) between the reader and the electronic entity. This intermediary checks the orientation condition before allowing data transmission, acting as a security gatekeeper that prevents involuntary transmission while maintaining authorized communication
2Object-affected harmful factors
If position sensor is added to control data transmission, then security is improved, but device complexity increases
Solution Approach 1:
The patent leverages the universality principle by utilizing existing multi-functional components in modern electronic devices. The position sensor can be integrated with other device functions (such as screen orientation detection in smartphones), allowing security enhancement without proportionally increasing overall device complexity
Solution Approach 2:
The patent segments the security control function into a separate orientation verification module that operates independently from the main communication protocol. This segmentation allows the security feature to be added modularly, minimizing impact on the overall system complexity while maintaining clear functional separation

Function Achieved in This Case
This solution allows users to control data transmission, enhancing security by ensuring that data is only exchanged when the device is in a predetermined orientation, thus preventing involuntary data transmission and enhancing user control over sensitive information.
Implementation Method 1
The measured orientation is for example an angular value relative to the vertical, defined by the earth's gravity.
