Device Security System for Unauthorized Access Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices such as cellular phones, PDAs, and laptops are susceptible to loss, theft, or unauthorized use, leading to data breaches and misuse, with unauthorized users often accessing sensitive information before the owner is aware of the issue.
Innovation Solution
A system and method that alters the device's functionality to assist in recovery, provides notifications to unauthorized users on how to return the device, and monitors unauthorized usage, including the use of wireless communication to alert the authorized user and potentially disable or restrict device access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device provides full access to unauthorized users, then ease of operation is maintained, but security and data protection deteriorate
Solution Approach 1:
The system performs preliminary actions by monitoring device usage patterns and establishing baseline behavior profiles before unauthorized access occurs. This allows the system to detect deviations from normal usage and trigger security responses proactively, preventing harmful access rather than reacting after the fact.
Solution Approach 2:
The system implements continuous feedback loops by monitoring device usage in real-time, comparing current behavior against established patterns, and dynamically adjusting access controls based on detected anomalies. This feedback mechanism enables the system to maintain security while allowing legitimate access, resolving the contradiction between ease of operation and protection against unauthorized access.
2Object-affected harmful factors
If the device functionality is restricted to prevent misuse, then security improves, but ease of operation and device utility deteriorate
Solution Approach 1:
The system dynamically adjusts device functionality based on detected usage patterns and security threats. Instead of static restrictions, the system modifies access levels and functional availability in real-time, allowing full functionality during normal use while automatically restricting access when unauthorized usage is detected, thus maintaining both security and operational flexibility.
Solution Approach 2:
The system changes operational parameters such as access credentials, functional permissions, and device state based on detected usage patterns. By dynamically modifying these parameters in response to security events, the system can prevent misuse while preserving full device functionality for authorized users, resolving the contradiction between security restrictions and operational utility.
3Reliability
If monitoring of unauthorized use is implemented, then security detection improves, but device complexity increases
Solution Approach 1:
The system implements self-service monitoring by automatically collecting usage data, analyzing patterns, and detecting unauthorized access without requiring external monitoring infrastructure. The device monitors itself and its immediate environment, reducing the need for complex external systems while maintaining high detection capability through intelligent analysis of usage patterns.
Solution Approach 2:
The system creates simplified copies or models of normal usage patterns that can be easily compared against actual device usage. By working with these simplified behavioral models rather than complex detailed analyses, the system achieves effective unauthorized use detection while maintaining relatively simple implementation, resolving the contradiction between detection reliability and system complexity.
Data Source
AI summary
The invention is directed to systems and methods for detecting the loss, theft or unauthorized use of a device and/or altering the functionality of the device in response. In one embodiment, a device monitors its use, its local environment, and/or its operating context to determine that the device is no longer within the control of an authorized user. The device may receive communications or generate an internal signal altering its functionality, such as instructing the device to enter a restricted use mode, a surveillance mode, to provide instructions to return the device and/or to prevent unauthorized use or unauthorized access to data. Additional embodiments also address methods and systems for gathering forensic data regarding an unauthorized user to assist in locating the unauthorized user and/or the device.
