Solution Overview
Problem
Portable information devices face challenges in providing effective security due to limitations in processor power and memory capacity, which are constrained by the need for affordability, portability, and usability, making it impractical to increase processor power and data storage substantially to enhance security.
Innovation Solution
A dynamically configurable security arrangement that automatically configures security settings based on the device's location and computing capacity, allowing for selective use of local or remote security services to optimize security and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If processor power and data storage capacity are increased to provide improved security, then security effectiveness is improved, but device portability, usability, and cost are worsened
Solution Approach 1:
The security system is segmented into multiple functional modules (firewall module, antivirus module, spyware detection module, etc.) that can be independently activated or deactivated based on the security risk level. This allows the device to maintain strong security capabilities when needed while reducing processor and memory requirements during normal operation, thus preserving portability.
Solution Approach 2:
The security arrangement dynamically adjusts its configuration based on the current security risk level detected by the risk detection module. When high risk is detected, the system activates enhanced security measures with higher processor and memory requirements. When risk is low, the system operates in a lighter configuration, maintaining portability while providing adequate security.
2Reliability
If processor power and data storage capacity are increased to provide improved security, then security effectiveness is improved, but device usability and performance are worsened
Solution Approach 1:
By dividing security functions into separate modules, the system can activate only the necessary modules based on the detected risk level. This prevents the constant high resource consumption that would result from running all security modules at full capacity, thereby maintaining better device performance and usability while still providing effective security when needed.
Solution Approach 2:
The system dynamically configures security module activation based on real-time risk assessment. This dynamic adjustment ensures that security effectiveness is maintained at appropriate levels without consistently demanding maximum processor power and memory, thus preserving device usability and overall performance for the user.
3Reliability
If processor power and data storage capacity are increased to provide improved security, then security effectiveness is improved, but battery life is worsened
Solution Approach 1:
The modular security architecture allows the system to activate only the necessary security modules based on the current risk level. This reduces the average power consumption compared to running all security functions at full capacity continuously, thereby extending battery life while maintaining effective security protection when threats are detected.
Solution Approach 2:
The dynamic configuration of security modules based on real-time risk assessment ensures that the device consumes maximum power only when and where security threats are detected. During normal low-risk operation, the system operates in a lower-power mode, significantly extending battery life while maintaining adequate security effectiveness.
4Reliability
If security applications require significant processor resources and memory capacity, then security effectiveness is improved, but device affordability is worsened
Solution Approach 1:
By implementing security as separate, optional modules rather than a monolithic system, the patent enables devices to be manufactured with varying levels of security capability. This modular approach allows manufacturers to produce more affordable devices with basic security modules while offering upgraded models with comprehensive security suites, thus improving accessibility without sacrificing effectiveness.
Solution Approach 2:
The dynamic security configuration allows devices with lower hardware specifications to provide adequate security by activating only the necessary modules based on risk level. This reduces the average hardware requirements needed for effective security, making devices more affordable to manufacture and purchase while maintaining security effectiveness through intelligent resource allocation.
