Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing forensic data collection methods from mobile devices are inefficient and costly, as they often involve exhaustive data imaging, which is not necessary in every case and lacks sufficient security and efficiency.

Innovation Solution

A method involving a handshake token process to securely collect and transmit a subset of data from mobile devices, using cryptographic tokens and secure uniform-resource locators to ensure data integrity and security, independent of the device's operating system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If exhaustive data imaging is performed on mobile devices, then complete forensic evidence is collected, but the process becomes more expensive and time-consuming

Engineering Contradiction:

Improvecompleteness of forensic evidenceVSAvoidefficiency of data collection

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent extracts only the necessary subset of data from mobile devices based on case-specific requirements rather than performing exhaustive imaging. The system identifies and collects only relevant data elements needed for the particular forensic case, eliminating unnecessary data collection overhead while maintaining evidence completeness for the specific investigative needs

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the data collection process into targeted categories and allows selective collection based on case requirements. Instead of treating the device as a monolithic data source, the system divides data into manageable segments that can be individually selected, collected, and processed according to specific forensic needs, improving efficiency while maintaining necessary evidence integrity

Inventive Principle:

Principle #1Segmentation

2Reliability

If exhaustive data imaging is performed on mobile devices, then complete forensic evidence is collected, but the process becomes more time-consuming

Engineering Contradiction:

Improvecompleteness of forensic evidenceVSAvoidduration of data collection

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary actions by pre-identifying relevant data sources and collection parameters before actual data collection begins. The system prepares collection profiles, identifies target data elements, and configures collection parameters in advance, which streamlines the actual data gathering process and reduces overall collection time while ensuring necessary evidence is captured

Inventive Principle:

Principle #10Preliminary action

3Productivity

If traditional forensic collection methods are used, then data is collected, but security and chain-of-custody are insufficient

Engineering Contradiction:

Improvesimplicity of data collectionVSAvoidsecurity and chain-of-custody

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces cryptographic tokens and secure locators as intermediary elements between the data collection process and the forensic server. These intermediaries establish verified communication channels, authenticate data sources, and maintain chain-of-custody documentation throughout the collection process, enhancing security and reliability without significantly complicating the overall workflow

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback mechanisms that continuously verify and document the chain-of-custody during data collection. The system provides real-time confirmation of data integrity, authentication status, and security protocol compliance, allowing operators to monitor and verify the security of the collection process while maintaining operational simplicity

Inventive Principle:
