Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based security control systems face challenges in accurately determining the location of movable devices relative to fixed devices, leading to potential security threats and limitations in granting access or authority based on secure locations, especially in regions without fixed devices or where location detection is unreliable.
Innovation Solution
A method and device for security control that detects multiple devices, determines a security level based on device type and number of detections, and applies user-specific policies to allow or restrict operations, incorporating necessary and related location reference devices for enhanced security authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location-based security control is implemented using a single fixed device, then the security control function can be provided, but the location determination accuracy deteriorates when the fixed device location or information is arbitrarily changed
Solution Approach 1:
The patent classifies reference devices into different types (necessary location reference devices and related location reference devices) with different weights. Necessary reference devices have higher weight and are required for basic security control, while related reference devices have lower weight and provide supplementary location information. This local quality differentiation ensures that the security control reliability is maintained through necessary devices while improving location determination precision through multiple related devices.
Solution Approach 2:
The patent combines multiple reference devices (both necessary and related) to determine the location of a movable device. By merging the location information from multiple devices and calculating weighted distances, the system achieves more accurate location determination than using a single fixed device, thereby resolving the contradiction between security control reliability and location determination precision.
2Adaptability or versatility
If existing location-based operation is used, then service guidance can be provided, but security control cannot be effectively applied in regions without fixed devices or where location detection is unreliable
Solution Approach 1:
The patent creates a universal location-based security control system that can operate in both regions with fixed devices and regions without fixed devices. By allowing the movable device to detect multiple reference devices (necessary and related) and calculate its location relative to these devices, the system provides adaptability to different environments while maintaining security control reliability through the weighted calculation method and policy-based access control.
3Reliability
If multiple devices are detected and security levels are determined based on device type and number of detections, then security control reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the reference devices into two categories: necessary location reference devices and related location reference devices. This segmentation simplifies the system by providing clear roles for each device type. Necessary devices are required for basic security control, while related devices provide additional location information. The segmentation approach improves security control reliability without significantly increasing system complexity, as the classification and weighted calculation can be implemented through standard software logic.

AI summary
A method, a device and a computer program for controlling security of a device based on a relative location of a device and a recording medium thereof are described. A method for security control based on a relative location of a first device may include detecting at least one second device; based on at least one of a device type or the number of device detections of the at least one second device, determining a security level of the first device; and allowing or restricting a specific operation of the first device based on the security level. The device type may include at least one of a necessary location reference device or a related location reference device.
