Network Delivery Verification Using Physical Characteristics

Solution Overview

Problem

Current methods for securely delivering information from a network device to a user device lack verification of physical characteristics, which can compromise security and authenticity in communication sessions.

Innovation Solution

A system that verifies network delivery of information by using physical characteristics such as MAC addresses, geographical locations, and time of delivery, implemented through a server device that cross-checks these characteristics with a database to authenticate the recipient device before allowing communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical characteristic verification is added to secure information delivery, then security and authenticity are improved, but device complexity and verification time increase

Engineering Contradiction:

ImprovesecurityVSAvoidverification process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-establishing the relationship between physical characteristics (MAC address, geographical location, time) and logical addresses in a database before information delivery. When information needs to be delivered securely, the system simply queries this pre-established database to verify if the recipient's physical characteristics match the expected values, rather than performing complex verification calculations in real-time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a database as an intermediary component that stores the mapping relationships between physical characteristics and logical addresses. This database acts as a mediator between the sender and recipient, automatically verifying whether the recipient's physical characteristics match the expected values associated with the logical address, thereby simplifying the verification process while enhancing security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If physical characteristic verification is implemented, then authenticity is improved, but loss of time in verification process increases

Engineering Contradiction:

ImproveauthenticityVSAvoidverification time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing the relationship between physical characteristics (MAC address, geographical location, time) and logical addresses in a database before information delivery. When information needs to be delivered securely, the system simply queries this pre-established database to verify if the recipient's physical characteristics match the expected values, rather than performing complex verification calculations in real-time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The verification process is designed to be self-service oriented, where the system automatically queries the database to verify physical characteristics without requiring manual intervention. The database itself serves the verification function by automatically comparing the recipient's physical characteristics against the stored expected values, reducing both time and human resource requirements.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If physical characteristics are used for verification, then security against misuse is improved, but device complexity increases

Engineering Contradiction:

Improvemisuse preventionVSAvoidsystem structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent introduces a database as an intermediary component that stores the mapping relationships between physical characteristics and logical addresses. This database acts as a mediator between the sender and recipient, automatically verifying whether the recipient's physical characteristics match the expected values associated with the logical address, thereby simplifying the verification process while enhancing security.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The verification system is designed with multi-functionality, using a single database structure to store and verify multiple types of physical characteristics (MAC address, geographical location, time) against logical addresses. This universal approach allows the system to prevent various forms of misuse (device substitution, location spoofing, time-based attacks) through a unified verification mechanism, reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A device may include a network interface configured to receive verification requirements and a message from a source device. In addition, the device may include a processor configured to receive a request from a destination device to send the message to the destination device, validate a logical address provided in the message based on a physical characteristic described or referenced in the verification requirements, and send the message to the destination device when the processor successfully validates the logical address based on the physical characteristic.
