Location-Based Device Locking to Prevent Password Disclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing information terminals, such as entering a password, may inadvertently disclose the password when used in public locations with multiple individuals, compromising security.
Innovation Solution
An information processing device with a lock function that restricts user operations based on a specified location, using an input unit for receiving a password and location, a mode setting unit to switch to a restricted mode, and a releasing unit to unlock when the device reaches the designated location, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a password is entered to unlock an information terminal, then the terminal can be accessed and used, but the password may be divulged to third parties in public locations
Solution Approach 1:
The authentication process is divided into two independent stages: location verification and password verification. The location check acts as a preliminary filter that determines whether password input is even required, separating the security verification into distinct functional segments that reduce overall risk
Solution Approach 2:
The location verification serves as an intermediary mechanism between the user and the password authentication system. By introducing this intermediate check, the system determines whether password entry should be permitted based on location context, thereby preventing password exposure in public settings
2Object-affected harmful factors
If location-based restrictions are implemented, then password disclosure is prevented, but device functionality is limited until the specified location is reached
Solution Approach 1:
The system dynamically adjusts device functionality based on real-time location data. When the device detects it has reached the specified location, it automatically transitions from a restricted state to an unlocked state, making functions available without requiring password re-entry. This dynamic adaptation resolves the contradiction by making restrictions temporary and context-dependent

AI summary
An information processing device having a lock function for restricting user operations and a mechanism executed by this information processing device are provided in which the information processing device includes: an input unit for receiving a first password and a specified location from a user; a mode setting unit for switching to a restricted mode restricting at least some of the functions of the information processing device in response to receiving the first password and location; and a releasing unit for releasing the restricted mode on condition that the information processing device has reached the specified location.
