Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack an efficient method to manage and secure sensitive temporary data in transportation systems, particularly in vehicles, where data security and privacy are critical.
Innovation Solution
A method and system that determine a portion of memory in a transport for storing sensitive temporary data, set a hardware threshold for the maximum number of reads, and clear the data when the threshold is reached, using a hardware-enabled trigger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensitive temporary data is stored in memory for extended access, then data usability is improved, but data security deteriorates due to increased exposure risk
Solution Approach 1:
The system pre-configures a read counter mechanism and maximum read threshold before storing sensitive temporary data in memory. The hardware monitor continuously tracks read operations and automatically triggers data clearance when the threshold is reached, eliminating the need for manual intervention and ensuring consistent security enforcement.
Solution Approach 2:
The patent replaces manual data management processes with an automated hardware-based monitoring system. The hardware monitor circuitry directly interfaces with memory and processor to enforce read limits and trigger automatic data clearance, substituting human-operated security protocols with reliable mechanical/electronic enforcement.
2Object-affected harmful factors
If data is cleared automatically after maximum reads, then data security is improved, but data availability deteriorates when data is needed beyond the threshold
Solution Approach 1:
The system pre-establishes the maximum read threshold and read counter mechanism before data storage operations begin. This preliminary configuration ensures that both security enforcement and data availability requirements are built into the system architecture from the outset, allowing predictable behavior throughout the data lifecycle.
Solution Approach 2:
The hardware monitor implements continuous feedback by tracking each read operation against the maximum threshold and automatically triggering data clearance when the limit is reached. This closed-loop control ensures that data availability is maintained within secure boundaries, with the system responding dynamically to usage patterns.
3Device complexity
If manual data management is used, then system complexity is reduced, but security enforcement reliability deteriorates due to human error
Solution Approach 1:
The system implements self-service security enforcement through automated hardware monitoring that independently tracks read operations, compares against thresholds, and triggers data clearance without human intervention. This eliminates reliance on manual security procedures while maintaining manageable system complexity through integrated hardware solutions.
Solution Approach 2:
The patent replaces manual data management processes with automated hardware-based monitoring and enforcement mechanisms. The hardware monitor circuitry directly interfaces with memory and processor to enforce read limits and trigger automatic data clearance, substituting human-operated security protocols with reliable mechanical/electronic enforcement.

AI summary
An example operation includes one or more of determining a portion of memory in a transport for storing sensitive temporary data, setting a hardware threshold of a maximum number of reads of the data from the portion of memory, and clearing the data from the portion of memory with a hardware-enabled trigger in response to the maximum number of reads is reached.
