Proximity-Based Device Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often face security and privacy issues when used by individuals other than their primary users, particularly due to relaxed security settings and unauthorized access, especially in portable devices.
Innovation Solution
Implementing a system that varies the functionality of electronic devices based on the proximity of the primary user, using threshold distances to transition between access states, enabling or disabling features such as email, contact lists, and navigation functions, and employing secondary devices and biometric confirmation to authenticate user identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If security measures are relaxed to allow convenient access by primary users, then ease of operation is improved, but security and privacy protection deteriorates when devices are used by other persons
Solution Approach 1:
The patent implements dynamic security states that automatically transition based on detected user proximity. The device monitors whether a primary user is present and adjusts security measures in real-time: when the primary user is detected, security is relaxed to allow convenient access; when absent, security is strengthened to prevent unauthorized access. This dynamic adaptation resolves the contradiction by making security measures flexible rather than static.
Solution Approach 2:
The system changes the security parameter (access restrictions) based on the detected proximity of the primary user. When the primary user is within a threshold distance, the device transitions to a second access state with relaxed security; when beyond the threshold, it transitions to a first access state with enhanced security. This parameter change approach allows the device to optimize both ease of operation and security protection depending on user presence.
2Ease of operation
If personal information is made accessible for convenience, then ease of operation is improved, but loss of information security increases when devices are shared or lost
Solution Approach 1:
The patent applies dynamic control to information access based on user proximity detection. The device automatically adjusts what information is accessible: when the primary user is present, full access to personal information is permitted; when absent, access to personal information is restricted. This dynamic information access control prevents privacy loss while maintaining convenience for authorized users.
Solution Approach 2:
The system applies different access qualities to different types of information based on user presence. When the primary user is detected, high-quality access (full access) is provided to personal information; when absent, low-quality access (restricted access) is applied. This local quality differentiation ensures that sensitive information is protected while allowing necessary access when authorized.
3Ease of operation
If devices are made portable for convenience, then ease of operation is improved, but vulnerability to unauthorized use increases
Solution Approach 1:
The patent implements dynamic security states that automatically transition based on detected user proximity. The device monitors whether a primary user is present and adjusts security measures in real-time: when the primary user is detected, security is relaxed to allow convenient access; when absent, security is strengthened to prevent unauthorized access. This dynamic adaptation resolves the contradiction by making security measures flexible rather than static.
Solution Approach 2:
The device performs self-service security monitoring by automatically detecting user proximity and adjusting its own security state without requiring manual user intervention. The system continuously monitors for the presence of the primary user and autonomously transitions between security states, providing self-service protection against unauthorized use while maintaining portability convenience.

AI summary
Examples of embodiments provide systems and methods for varying the functions of an electronic device according to a physical relationship (e.g. the distance) between the electronic device and the primary user (e.g., owner) of the electronic device. The device may measure the distance using a wireless signal from a secondary device carried by or associated with the primary user. In some embodiments, the electronic device may change its functions based on its environment, in combination with the distance between the electronic device and the primary user. Environmental factors may include the device's location, the device's velocity, and the date and time of day.
