Mobile Threat Detection for Selective Data Transmission Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network-based finance systems face risks as malicious actors can force users to transfer financial data against their will, necessitating a solution to protect user data in threat conditions.
Innovation Solution
Mobile devices employ sensors to detect threat conditions, transitioning to a data restriction state that blocks transmission of sensitive data while allowing transmission of non-sensitive data, and outputting error messages to thwart unauthorized transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile device allows transmission of all data types for normal operations, then ease of operation and productivity are maintained, but security against malicious actors deteriorates when threat conditions occur
Solution Approach 1:
The patent implements dynamic data transmission control by transitioning between normal operation mode and data restriction state based on detected threat conditions. Sensors monitor for threats and trigger state changes that dynamically adjust which data types can be transmitted, allowing the system to adapt its security posture to current conditions rather than maintaining a static configuration
Solution Approach 2:
The patent applies different transmission restrictions to different data types based on their sensitivity. Instead of blocking all data transmission uniformly, the system selectively restricts sensitive data types (financial data, health data, credentials) while allowing non-sensitive data types to continue transmitting during threat conditions, creating localized quality differences in transmission permissions
2Reliability
If the mobile device blocks transmission of sensitive data during threat conditions, then data security is improved, but loss of information increases due to prevented legitimate transactions
Solution Approach 1:
The patent changes the transmission parameter (permission status) based on the detected threat condition. When threats are detected, the system modifies the parameter state from 'allow transmission' to 'restrict transmission' for sensitive data types. This parameter change mechanism enables conditional control that balances security needs with legitimate transaction requirements
3Reliability
If the mobile device implements comprehensive data restriction controls, then data security is enhanced, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent creates a universal data control mechanism that handles multiple data types (financial, health, credentials, communications) through a single integrated system. The data manager module serves multiple functions: monitoring threat conditions, determining which data types to restrict, and enforcing transmission controls across different applications and protocols, reducing overall system complexity through consolidation

AI summary
Techniques for data control based on threat condition are described and are implementable to enable data transactions to be controlled based on threat conditions. For instance, a mobile device can receive sensor data indicating one or more threat condition triggers associated with a user of the mobile device. The mobile device can execute, based at least in part on the one or more threat condition triggers, a data control process to restrict one or more first data types from being transmitted by the mobile device.
