Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If machine learning is used to evaluate data from multiple channels, then detection accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the detection process into separate modules: data collection from multiple channels, data transformation from unstructured to structured format, machine learning evaluation, and alert generation. This segmentation allows each module to be optimized independently while working together to achieve high detection accuracy across multiple communication channels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a data transformation layer as an intermediary between raw data from multiple channels and the machine learning evaluation layer. This intermediary converts unstructured data into a standardized structured format, simplifying the subsequent analysis process and reducing the complexity burden on the machine learning models.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If data from multiple communication channels is analyzed, then threat identification capability is improved, but processing time increases

Engineering Contradiction:
Improvethreat identification capabilityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary data transformation and structuring of data from multiple channels before it reaches the machine learning evaluation stage. By preparing and organizing the data in advance, the subsequent threat identification process is accelerated, reducing overall processing time while maintaining comprehensive multi-channel analysis.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If triggering content is evaluated across channels, then unauthorized activity detection is improved, but false positives may increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms that continuously evaluate detected triggering content across multiple channels and adjust detection parameters accordingly. By analyzing patterns and outcomes of previous detections, the system refines its ability to distinguish between actual unauthorized activity and false positives, improving overall detection reliability.

Inventive Principle:
Principle #23Feedback

AI summary

Systems for dynamically detecting unauthorized activity are provided. A system may receive data from one or more computing devices associated with one or more different channels of communication (e.g., email, telephone, instant messaging, internet browsing, and the like). The received data may be formatted or transformed from an unstructured format to a structured format for further analysis and evaluation. In some arrangements, machine learning may be used to determine whether triggering content was identified in data received from the one or more systems and to evaluate the identified triggering content to determine whether the content, alone or in combination with triggering content from other channels of communication, may indicate an occurrence of unauthorized activity. If so, the identified occurrence may be evaluated to determine whether a false positive has occurred. If a false positive has not occurred, an alert or notification may be generated and/or operation or functionality one or more communication channels may be modified.
