Proximity-Based Device Locking Using Wireless Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security measures for computing devices, such as screen lock policies, rely on time-based inactivity, requiring users to repeatedly enter credentials, which is inconvenient and may lead to workarounds that compromise security.
Innovation Solution
Implementing a proximity-based security system that uses devices like smartphones to authenticate and control access to laptops or other devices, automatically locking or unlocking them based on proximity, eliminating the need for frequent credential entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time-based screen lock policies are implemented, then security is improved, but user convenience deteriorates due to frequent credential entry requirements
Solution Approach 1:
The patent replaces the mechanical credential entry system (typing passwords, using PINs) with a proximity-based authentication system using wireless communication technologies such as Bluetooth, NFC, or RFID. When an authorized device approaches the locked device, the system automatically authenticates based on the detected proximity, eliminating the need for manual credential input while maintaining security.
Solution Approach 2:
The system enables self-service authentication where the authorized device automatically performs the unlocking action when it detects proximity to the locked device. The user simply needs to bring their device close, and the system handles the entire authentication and unlocking process automatically without requiring the user to manually enter credentials or interact with the lock screen.
2Reliability
If longer and safer passwords are required, then security is improved, but operational complexity increases due to password management requirements
Solution Approach 1:
The patent replaces the complex password management system with a proximity-based authentication system. Instead of requiring users to create, remember, and manage long and secure passwords, the system uses wireless proximity detection between authorized devices. This substitution eliminates password management complexity entirely while maintaining or improving security through cryptographic authentication protocols.
3Reliability
If screen locking policies are enforced, then data protection is improved, but user efficiency deteriorates due to repeated authentication requirements
Solution Approach 1:
The patent enables continuous uninterrupted work by eliminating the need to stop and re-authenticate when the device locks. The proximity-based system keeps the device unlocked as long as the authorized device remains in proximity, allowing users to maintain continuous workflow without interruption. The useful action of working on the device continues uninterrupted while the security protection remains active through automatic proximity monitoring.
Solution Approach 2:
The system provides self-service security where the proximity detection and authentication happen automatically without requiring user intervention. The device continuously monitors for the presence of authorized devices and automatically maintains the unlocked state, freeing the user to focus on productive work without being burdened by authentication management.
Data Source
AI summary
A proximity-based system for performing operations is disclosed. A device may be registered with a system configured to orchestrate proximity-based actions and then associated with other devices. A distance between a first device and a second device may be determined. The distance is used to determine whether an operation at the second device should be performed. Performing the operation is executed by generating a prompt on the first device to authorize the operation. The authorization is authenticated using cryptography or without passwords and the operation is performed at the second device when authentication is successful. This may allow a device to be unlocked/locked based on a proximity of another device associated with the original device.
