Mobile Device Security Mode Selection via Motion and Time Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices require users to constantly enter a security code, even in secure zones, leading to inconvenience and restricting access for authorized users.
Innovation Solution
A method and apparatus for selectively applying a security mode in a mobile device, which includes detecting motion using sensors, activating the camera to photograph objects in specific conditions, and displaying menus to receive passwords based on the device's location and time conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security mode is enabled to protect mobile device access, then security reliability is improved, but ease of operation deteriorates due to constant password entry requirements
Solution Approach 1:
The patent applies dynamics by making the security mode configurable and adaptable rather than fixed. The system dynamically adjusts between security mode and non-security mode based on user needs, allowing the security behavior to change over time. This resolves the contradiction by enabling users to toggle security on/off, so when security is needed it provides protection, and when not needed it disappears to improve ease of operation.
Solution Approach 2:
The patent changes the parameter of security enforcement from a binary state to a configurable state. By introducing a setting that allows users to enable or disable security mode, the system changes the parameter of security application. This resolves the contradiction by allowing the security parameter to be adjusted - when set to security mode, reliability is improved; when set to non-security mode, ease of operation is improved.
2Reliability
If security code is required for all access attempts, then security reliability is improved, but adaptability deteriorates by preventing authorized users without codes from accessing
Solution Approach 1:
The patent applies dynamics by making the access control mechanism adaptable to different scenarios. The system can dynamically switch between requiring security codes and allowing direct access based on the security mode setting. This resolves the contradiction by enabling the system to adapt its access requirements - in security mode it requires codes for reliability, in non-security mode it allows direct access for adaptability.
Solution Approach 2:
The patent changes the parameter of access control from mandatory to optional. By introducing a configurable security mode parameter, the system can adjust its access control behavior. When security mode is enabled, the parameter requires code verification for reliability; when disabled, the parameter allows direct access for adaptability. This resolves the contradiction by making the access control parameter flexible rather than fixed.

AI summary
A computer-readable medium contains codes as a program to perform a method of a mobile device having a memory, a sensor, a camera, a panel to display a menu image and to receive a user input, and a network interface to communicate with an external device. The method includes detecting a motion of the mobile device by using the sensor, activating the camera in response to the detected motion to photograph an object when the mobile device is in a time condition, and not activating the camera in response to the detected motion when the mobile device is not in the time condition.
