Context-Aware Device Functionality Limiting for Sensitive Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices with sensitive data, such as digital wallets, are vulnerable to theft and malicious use due to hardware or software vulnerabilities, leading to potential fraud and data compromise, with existing security measures failing to adequately protect against such risks.
Innovation Solution
Implementing methods on user computing devices to detect vulnerabilities and risks through real-time data processing and contextual analysis, limiting device functionality and data access when threats are detected, and automatically reversing limitations when the risk is mitigated, using a combination of on-device and proximate data analysis to impose and lift restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time data processing and contextual analysis are implemented to detect vulnerabilities and risks, then security of sensitive data is improved, but device complexity and computational resource consumption increase
Solution Approach 1:
The security system is divided into separate functional modules: a data detection component that collects and processes device data, a risk assessment component that analyzes vulnerabilities, and a limitation application component that enforces security restrictions. This modular segmentation allows each component to specialize in specific tasks, improving overall security effectiveness while managing system complexity through organized decomposition of the security functionality.
Solution Approach 2:
The system continuously monitors and analyzes device data in real-time to detect vulnerabilities and risks before they can be exploited. By performing preliminary detection and assessment of security threats, the system can proactively apply limitations to protect sensitive data before actual compromise occurs, rather than reacting after a breach has happened.
2Reliability
If device functionality is limited when risks are detected, then protection against fraud and malicious use is improved, but usability and accessibility of device functions deteriorate
Solution Approach 1:
The security limitations applied to device functionality are dynamic rather than static. The system continuously evaluates device data and adjusts the level of restriction based on current risk conditions. When vulnerabilities are detected, limitations are applied; when risks are mitigated or resolved, limitations are automatically reversed or reduced. This dynamic adaptation allows the system to maintain strong security protection while preserving normal device usability when safe, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The system implements continuous feedback loops where device data is constantly monitored, risk levels are reassessed, and limitation levels are adjusted accordingly. This feedback mechanism ensures that security measures remain appropriately calibrated to actual threats, preventing both over-restriction that would harm usability and under-restriction that would compromise security. The automatic reversal of limitations when risks are mitigated provides positive feedback that maintains usability while preserving security.

AI summary
There are provided systems and methods for limiting device functionality based on data detection and processing. A user computing device may include sensitive or confidential data and/or processes that utilize such data that a malicious party may wish to abuse, such as an electronic transaction processing application that uses financial data of a user. The device may therefore be compromised by the malicious party if the device becomes accessible to that party. The device may utilize one or more processes to detect device data determine data proximate to the device and/or contextual data in order to determine whether limitations on application processes are required based on the potential nearby risk. If the nearby risk indicates the device application processes may be in danger, the device may impose limitations on the processes and/or wipe data. The device may also alert other devices or nearby users.
