Wireless Leash Proximity Tracking for Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high demand and portability of devices like smartphones make them prone to loss or theft, leading to the risk of valuable information being compromised, and existing solutions lack effective methods for real-time tracking and security measures.
Innovation Solution
Implementing companion and accessory devices that can be wirelessly leashed together, allowing them to estimate their proximity and perform specific operations when they exceed a threshold distance, such as alerting the user or initiating data synchronization, to prevent loss and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices are made portable and small in size, then ease of operation and user convenience are improved, but the risk of loss or theft increases
Solution Approach 1:
A wearable accessory device serves as an intermediary between the user and the companion device. The accessory continuously monitors proximity to the companion device and triggers alerts or notifications when separation is detected, providing an additional layer of security without affecting the portability of the main device.
Solution Approach 2:
The system implements continuous feedback by monitoring the wireless connection status between the companion device and accessory. When the connection is lost or proximity threshold is exceeded, the system provides immediate feedback through alerts, notifications, or haptic feedback to warn the user of potential device separation or theft.
2Adaptability or versatility
If devices store valuable personal information, then functionality and usefulness are improved, but the risk of information compromise increases
Solution Approach 1:
The system performs preliminary actions by continuously monitoring device proximity and connection status before unauthorized access can occur. When separation is detected, the system can trigger pre-configured security measures such as locking the device, notifying contacts, or initiating data protection protocols before the device falls into unauthorized hands.
Solution Approach 2:
The wearable accessory acts as an intermediary security layer that monitors and controls access to the companion device. It can mediate between the user and the device, providing an additional authentication factor or alerting the user before any unauthorized access attempts occur.
3Reliability
If manual authentication processes are required for device access, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service authentication by automatically verifying the proximity and connection status of authorized devices. The wearable accessory and companion device automatically authenticate each other through continuous proximity monitoring and wireless communication, eliminating the need for manual authentication while maintaining security.
Solution Approach 2:
The system uses continuous feedback from proximity sensors and wireless connection status to automatically manage authentication. When an authorized device is detected within proximity, access is automatically granted; when unauthorized devices or separation are detected, access is automatically restricted, providing both security and convenience.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables real-time tracking and alerts for potential loss, helping users recover their devices and ensuring secure data synchronization, thereby reducing the risk of information compromise and theft.
Implementation Method 1
one device can periodically attempt to detect a signal from the other device
Data Source
AI summary
Companion and accessory devices can be wirelessly leashed together in a manner that enables the devices to estimate their proximities to each other. One device can periodically attempt to detect a signal from the other device. For each attempt, the attempting device can store an indication of whether the signal was detected. Further, a companion device or accessory device can detect signals from different wireless-capable devices in an environment. The companion device or the accessory device can configure an interface displayed on the companion device or the accessory device, respectively, based on signal information about the different wireless-capable devices in the environment.
