An integrated intrusion protection and notification device is deployed within the computer system, utilizing multiple sensors such as accelerometers, motion detectors, and RF signal strength indicators to monitor environmental changes and detect potential breaches, with redundant communication links and automatic data encryption or destruction mechanisms to ensure security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors and monitoring functions are added to detect physical intrusions, then detection capability and security reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (accelerometers, motion detectors, RF signal strength indicators, temperature sensors, humidity sensors, light sensors) and monitoring functions into a single integrated intrusion detection device that communicates with the computer system through a unified interface, resolving the contradiction by merging complex components into one coordinated system
Solution Approach 2:
The intrusion detection device performs multiple functions simultaneously including motion detection, environmental monitoring, alarm notification, and data protection triggering, allowing a single device to address various security concerns without requiring separate systems for each function
2Object-affected harmful factors
If automatic data encryption or destruction mechanisms are implemented upon detecting intrusion, then data security is improved, but loss of information may occur due to automatic destruction
Solution Approach 1:
The system implements preliminary protective actions by encrypting data before potential intrusion occurs and only triggers destruction as a last resort when intrusion is confirmed, allowing preventive security measures to be taken without immediately losing information
Solution Approach 2:
The system uses feedback from multiple sensors to continuously monitor the environment and adjust its response, only triggering data destruction when multiple intrusion indicators are confirmed, thereby reducing false positives and unnecessary information loss
3Reliability
If redundant communication links are added to ensure reliable alarm notification, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple communication methods (network interface, wireless communication, cellular communication) into a single notification system that automatically selects alternative paths if one fails, resolving the contradiction by merging communication channels into one multi-capable system

AI summary
Software intrusion protection systems to prevent remote access to sensitive data are very prevalent. In some cases, additional physical access protection may also be desired. By preventing physical access to a system an intruder may not be able to physically “steal” component parts of the system and then obtain their contents (or design criteria) at a remote site (e.g., after the physical theft). Monitors are provided to detect potential access to a secure computer system and identify if inappropriate access to the secure computer system is obtained (or is imminent). In a case where unauthorized access is predicted, warnings and alerts may be sent prior to an actual breach. Upon determination that a breach may be likely to occur, techniques to protect data (e.g., erasure, destruction, etc.) and component parts may be initiated. Sensors monitor internal and external physical environmental conditions to assist in detection of intrusion.
