Password-Protected Mobile Device Recovery via Activation Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Password-protected mobile devices are difficult to recover when lost, as finding individuals is challenging due to the need for access to the device's contact information, which is locked behind a passcode.
Innovation Solution
A method and system that allow a password-protected mobile device to receive an activation event, analyze stored contact information, and automatically contact predefined numbers or send messages to locate the owner, even when the device is locked, using various activation events such as special keys, gestures, sounds, or motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password protection is enabled on mobile devices, then device security and data protection are improved, but device recoverability when lost is worsened
Solution Approach 1:
The system performs preliminary actions by automatically detecting loss conditions (such as device being stationary for a prolonged period or geofence violations) and proactively contacting predefined contacts before the owner realizes the device is lost. This preliminary detection and notification mechanism bridges the security gap by enabling recovery without requiring the finder to access protected contact information.
Solution Approach 2:
The lost device autonomously performs recovery actions by automatically contacting predefined contacts using stored contact information without requiring external intervention or password authentication. The device self-identifies its lost state and initiates the recovery communication sequence independently, maintaining security while enabling recoverability.
2Loss of information
If contact information is locked behind passcode, then data privacy is improved, but ability to locate owner of lost device is worsened
Solution Approach 1:
The contact information system is segmented into two distinct access paths: predefined contacts that are accessible without authentication for loss recovery purposes, and general contact list that remains protected by passcode. This segmentation allows the device to communicate owner location to specific recovery contacts while maintaining privacy protection for the broader contact database.
Solution Approach 2:
The system introduces an intermediary mechanism where the lost device itself acts as the mediator between the finder and the owner's contact information. Instead of requiring the finder to access protected contacts, the device autonomously contacts predefined numbers and relays location information, eliminating the need for the finder to breach security measures.
3Productivity
If automated contact system is implemented, then device recovery speed is improved, but device complexity is worsened
Solution Approach 1:
The system utilizes changes in device operational parameters (such as transition from mobile to stationary state, battery level thresholds, or geofence status changes) to trigger automated contact sequences. These parameter-based triggers provide a simple, elegant mechanism for detecting loss conditions without requiring complex artificial intelligence or decision-making algorithms.
Data Source
AI summary
An approach includes contacting a predefined contact information when a mobile device, which is password protected, is lost and subsequently found. The approach includes receiving an activation event predefined for a specified password protected mobile device, and receiving predefined contact information stored in the mobile device while the mobile device remains password protected, upon the receipt of the activation event.
