Context-Aware Program Control for Location-Based Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack sufficient security measures to prevent information leakage based on the environment where they are used, leading to potential unauthorized access and data exposure, especially when used outside secure settings.
Innovation Solution
An electronic device and control method that utilize short-range wireless communication with an information processing terminal to determine the device's location and proximity to a registered place, adjusting program control such as displaying password entry screens or switching operating systems based on these determinations to enhance security and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device implements strict security measures (password requirements, function limitations) to prevent information leakage, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies dynamics by making security measures variable rather than fixed. The processor dynamically adjusts password requirements and function limitations based on real-time determination of the device's location and communication status with the information processing terminal. When the device is determined to be at a registered place and in communication with the terminal, strict security measures are relaxed; when not in communication or at unregistered places, security measures are enforced, thus resolving the contradiction between security and ease of operation
Solution Approach 2:
The patent changes the parameter of security measure intensity based on environmental conditions. The processor modifies security parameters (password entry requirements, function availability) according to the determined location and communication state. This parameter change allows the system to adapt security stringency to the actual risk level, improving ease of operation in safe environments while maintaining security in risky environments
2Adaptability or versatility
If the electronic device continuously monitors location and communication status to adjust security measures, then adaptability to environment is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by having the processor perform multiple functions through a unified determination process. The same processor that executes programs also determines location status, communication state, and controls security measures. The information processing terminal serves multiple purposes: it acts as both a communication endpoint and a trigger for security policy changes. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while achieving high adaptability

AI summary
An electronic device performing short-range wireless communication with an information processing terminal, includes: a processor; a storage storing a program executed by the processor; and a communicator communicating with the information processing terminal by short-range wireless communication. The communicator receives place determination information indicative of a place where the information processing terminal lies. The processor determines whether the communicator is in short-range wireless communication with the information processing terminal, determines whether the information processing terminal is at a registered place registered in advance, based on the place determination information, and changes control of the program based on results of the determinations.
