Proximity Security Token for Theft Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security solutions for personal property and financial information are vulnerable to manipulation and theft, lacking robustness and effectiveness.
Innovation Solution
Implementing a proximity security token system that provides a wireless communication link between a protected device and a separate security token, enabling secure operations when connected and triggering security actions, such as disabling functionality or sounding alarms, when the link is interrupted, indicating potential theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security solutions (tracking devices, user codes, biometric identification) are implemented, then personal property and financial information theft is mitigated, but the solutions remain vulnerable to manipulation and disabling by creative thieves
Solution Approach 1:
The security system is divided into separate components: a proximity security token carried by the user and a protected device (personal property or financial instrument). This segmentation ensures that stealing one component does not compromise security, as the token must be physically present and communicate with the protected device for operations to proceed.
Solution Approach 2:
A proximity security token acts as an intermediary between the user and the protected device. The token establishes a secure communication channel and verifies presence before allowing operations, creating an additional layer of verification that prevents unauthorized access even if the protected device itself is compromised.
2Reliability
If a proximity security token with wireless communication link is implemented, then continuous verification of proximity is enabled, but device complexity increases
Solution Approach 1:
The complex security verification functionality is extracted into a separate, dedicated proximity security token. This token handles all proximity verification and communication tasks, keeping the protected device simple while providing robust security. The token can be removed or replaced independently without affecting the protected device.
Solution Approach 2:
The proximity security token serves multiple functions: establishing secure communication, verifying proximity, enabling/disabling device operations, and triggering security actions. This multi-functionality consolidates several security mechanisms into a single component, reducing overall system complexity while maintaining reliability.

AI summary
Disclosed embodiments comprise one or more security methods, systems or apparatus suitable to provide additional security to personal property or financial transactions. Embodiments feature a proximity security token which is physically separate from a protected device. A communications link is provided between the proximity security token and the protected device which communications link operates over a limited range. Thus, the presence and active operation of the limited range communications link between the proximity security token and protected device indicates that the protected device has not been lost and stolen. Interruption of the communications link indicates that the protected device may have been lost or stolen causing the commencement of security actions.
