Solution Overview

Problem

Traditional traffic enforcement systems lack secure handling of digital evidence packages, as they do not effectively track authenticity and integrity, making them vulnerable to digital threats and human errors during review and transmission.

Innovation Solution

A distributed ledger system is implemented to manage traffic violation data, ensuring transparency and security by logging all interactions and using package digests for validation, while also employing data sharding and access control to maintain confidentiality and reduce security risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional traffic violation management systems are used, then the system structure is simple, but the security and integrity tracking of digital evidence packages deteriorates

Engineering Contradiction:

Improveintegrity trackingVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the digital evidence package into distinct components: the original evidence data, a cryptographic hash (digest) of the evidence, and a chain of custody ledger. This segmentation allows each component to serve its specific function - the evidence remains intact while the hash and ledger track its integrity and movement through the system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A distributed ledger acts as an intermediary between the digital evidence packages and the various system components that handle them. The ledger records the chain of custody and validates integrity through cryptographic hashes, mediating the trust between different users and systems without requiring direct verification of every evidence package.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If digital evidence packages are reviewed by multiple nodes, then the thoroughness of review improves, but the security risk and exposure to threats increases

Engineering Contradiction:

Improvereview thoroughnessVSAvoidsecurity risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The distributed ledger serves as a secure intermediary that enables multiple nodes to review evidence packages without directly exposing them to each other. Each node can verify the integrity of evidence through the ledger's cryptographic records without needing to see or trust the raw evidence data itself, reducing the attack surface for malicious nodes.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual security verification processes with automated cryptographic validation. Instead of relying on human operators to securely handle and verify evidence packages, the system uses cryptographic hashes and distributed ledger validation to automatically ensure integrity and authenticity at each review stage.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If data is stored in a centralized manner, then the system complexity is low, but the confidentiality and privacy protection deteriorates

Engineering Contradiction:

ImproveconfidentialityVSAvoiddata management structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments data access and storage responsibilities across multiple distributed nodes rather than centralizing it. Each node maintains its own copy of the distributed ledger and can independently validate evidence packages, eliminating the single point of failure and enhancing confidentiality through distributed data management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of storing a single centralized copy of the data, the system creates and maintains multiple copies of the distributed ledger across different nodes. Each node has a copy of the chain of custody records, allowing the system to function continuously even if some nodes are compromised or fail.

Inventive Principle:

Principle #26Copying

4Reliability

If manual access control is used, then the system operation is simple, but the vulnerability to credential compromise increases

Engineering Contradiction:

Improveaccess securityVSAvoidaccess control mechanism

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system replaces manual access control mechanisms with automated cryptographic validation. Instead of relying on usernames and passwords that can be compromised, the system uses cryptographic hashes and digital signatures to automatically verify the authenticity and integrity of evidence packages at each node in the chain of custody.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Disclosed herein are methods and systems for managing traffic violation or enforcement data using a distributed ledger. The distributed ledger provides a transparent chain of custody/evidence related to all digital interactions with traffic violation or enforcement data. The distributed ledger can be audited for data accuracy and integrity by nodes making up the system each time one of the nodes interacts with the traffic violation or enforcement data. For example, a digital evidence package related to a traffic violation event can be generated by a node within the system and a package digest can be logged in the distributed ledger beginning with the creation of the digital evidence package and each time that the digital evidence package is processed, modified, or reviewed by nodes within the system.
