Identity Medium Proximity Activation via Sensor Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity carrier systems lack a robust mechanism to ensure that authentication functions are only activated when the authorized entity is in close proximity, preventing unauthorized access and misuse.
Innovation Solution
A method and system where an identity carrier's function is deactivated if the authorized entity is not within a predetermined vicinity, using a detection device to monitor entity-specific features and determine spatial distance, eliminating the need for manual activation, such as entering a PIN, and ensuring the function is only executed when the entity is present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the identity carrier function is always active, then ease of operation is improved, but security is worsened due to risk of unauthorized access
Solution Approach 1:
The system performs preliminary verification by detecting whether the authorized entity is present in the detection area before activating the identity carrier function. The sensor continuously monitors for entity-specific features (biometric data, RFID signal, etc.) and only enables the authentication function when the authorized entity is detected, preventing unauthorized use while maintaining ease of operation for legitimate users.
2Reliability
If manual activation (e.g., PIN entry) is required, then security is improved, but ease of operation is worsened
Solution Approach 1:
The system performs self-verification by automatically detecting the presence of the authorized entity through sensors and activating the identity carrier function without requiring manual intervention. The sensor monitors for entity-specific features and the system autonomously determines whether to enable authentication, eliminating the need for PIN entry while maintaining security through automatic presence verification.
3Reliability
If the detection area is monitored continuously, then security is improved, but energy consumption is worsened
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic detection where the sensor checks for the authorized entity's presence at intervals or triggers authentication function only when needed. The sensor monitors the detection area for entity-specific features and activates the identity carrier function based on detected presence, reducing energy consumption while maintaining security through periodic verification.

AI summary
The invention relates to a method for providing at least one function of an identity medium (2), wherein an entity that is authorized to carry the identity medium has at least one entity‑specific feature, wherein at least one sensing device monitors a sensing region (7), associated with the sensing device, for at least one entity‑specific feature, wherein a physical distance (A) between the identity medium and the entity or a physical distance (A2) between the sensing device and the entity is determined, wherein the function of the identity medium (2) is deactivated if the at least one entity‑specific feature has not been detected or the physical distance (A) is greater than a predetermined distance, wherein the at least one function of the identity medium (2) is activated if the at least one entity‑specific feature has been detected and the physical distance (A, A2) is less than the predetermined distance or equal to the predetermined distance, and also a system for providing a function of an identity medium.
