Data Taking Prevention TRIZ Cases
- In-Vehicle PHY Switching for Oscillator-Based ECU Intrusion Detection
Oscillator frequency checks let the PHY block spoofed ECU signals before processing, improving in-vehicle network intrusion detection.
- In-Vehicle Message Timing Control for Unauthorized Signal Detection
Timed event-message spacing improves unauthorized message detection in mixed periodic/event in-vehicle networks without wasting bandwidth.
- Network Graph Analysis for Non-Whitelist ICS Communication
Past communication links and similar terminal extraction help analysts assess non-whitelist ICS traffic with fewer false detections.
- Communication Link Prediction Graph for ICS Whitelist Accuracy
Predicting likely normal ICS communication links before operation cuts whitelist false detections and reduces analyst review burden.
- Firewall Transparency Control for Secure Network Camera Access
Authentication and firewall transparency settings enable secure WebRTC access to network camera video and audio without unrestricted viewing.
- Overlay-Underlay Network Blocking for Unauthorized IoT Communication
Unauthorized traffic is detected in the overlay network and blocked in the underlay network, extending low-cost protection to OA and IoT terminals.
- Overlay-Underlay Network Detection for Blocking Unauthorized Traffic
Unauthorized traffic is cross-checked between overlay alerts and underlay flow inconsistencies to block attacks at lower cost and with fewer false positives.
- Network-Coded Relay Diffusion for Blockchain Anonymity
Random differential relay with network coding obscures packet sources in blockchain propagation while preserving timely diffusion.
- Network-Coded Relay Diffusion for Anonymous Transaction Propagation
Randomized relay mapping and network-coded packets obscure transaction paths while maintaining fast propagation across blockchain nodes.
- In-Vehicle Network Message Detection via Periodic Reception Patterns
Monitors periodic message timing and frequency in vehicle networks to detect unauthorized messages that mimic authorized IDs.
- Abnormal Communication Detection Using FQDN Verification
FQDN verification filters CDN-driven IP address changes, cutting false abnormal communication alerts while preserving detection accuracy.
- Dual-Mode Communication With Obfuscated Ethernet Frames
Dual-mode communication permutes Ethernet frames in obfuscated mode, filtering invalid frames while retaining public-network compatibility.
- IoT Attack Detection Through Ephemeral Port Monitoring
Conventional security monitoring can miss IoT attacks on ephemeral ports; this approach analyzes terminal-to-device communications to identify unauthorized activity.
- In-Vehicle Communication Timing for Unauthorized Device Detection
Timing discrepancies in vehicle-network messages reveal unauthorized devices without relying on encryption keys, strengthening communication security.
- IoT Gateway Whitelist Creation from Normal Communication Data
A gateway requests normal IoT communication data to create verifiable whitelists and expose unintended traffic.
- Secure Mobile Communication Relay with Baseband Firewall
A secure mobile communication relay filters baseband packet data using a dedicated firewall function unit to enforce security policies.
- Dynamic Attribute Synchronization for Secure Authorization Verification
Synchronized dynamic changes to color, orientation, and volume prevent unauthorized copying while enabling automated verification without center queries.
- Malicious Script Detection Using Code Pattern and API Flow Analysis
A detection system analyzes web page scripts using code patterns and API flows to identify malicious content in real time.
- Network Malware Detection via Segmented Signature and Behavioral Analysis
A multi-staged scanning system filters known threats using signature matching while applying AI-based risk assessment to unknown content.
- Secure Data Transmission via Bidirectional Connection Messages
Bidirectional connection messages monitor transmission paths for disturbances, halting exchanges to re-authenticate clients and prevent unauthorized access.
- DRM Source Device Sink Certification via EDID Feedback
A DRM source device filters A/V data using sink vendor information to control signal transmission through DVI or HDMI interfaces.
- Sender Identity Verification via Unique Web Code
A sender identity verification method uses a unique web code to confirm the sender's authenticity.
- Local Server Intermediary for Remote Data Access
A local server mediates cross-connection operations between remote and local storage areas, resolving configuration complexity without dedicated software.
