Solution Overview

Problem

The widespread popularity of digital content distribution has made it challenging to effectively authenticate and manage content, as deepfake manipulated content can be difficult to detect, leading to potential legal and contractual violations.

Innovation Solution

A system for authenticating digital content using biometric and linguistic analysis, employing hardware processors and databases to compare biometric and linguistic profiles with predetermined values, determining authenticity through automated processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If deepfake detection methods are improved, then authentication reliability is improved, but device complexity and processing requirements increase

Engineering Contradiction:
Improveauthentication reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The authentication system divides the verification process into separate modules: biometric analysis module extracts facial features and compares them against stored data, while linguistic analysis module processes speech patterns and language characteristics. This segmentation allows each module to specialize in specific detection tasks, improving overall reliability without requiring a single overly complex system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system moves beyond traditional single-modality detection by adding multiple dimensions of analysis: visual biometric dimension (facial features, expressions), acoustic dimension (voice patterns, tone), and linguistic dimension (language model matching, script verification). This multi-dimensional approach significantly improves detection capability while keeping individual modules manageable in complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If automated authentication processes are implemented, then productivity and efficiency are improved, but loss of information and accuracy may increase

Engineering Contradiction:
Improveauthentication efficiencyVSAvoidinformation accuracy
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system incorporates multiple feedback mechanisms: biometric matching feedback compares extracted features against stored profiles with tolerance thresholds, linguistic analysis feedback verifies speech content against known scripts and language models, and cross-validation feedback ensures consistency between different analysis modules. This feedback loop maintains high accuracy in automated processing by continuously verifying results against multiple reference points.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-storing authentic biometric data, linguistic profiles, and script information in databases before authentication is needed. During automated processing, these pre-prepared reference data enable rapid comparison and verification without requiring complex real-time analysis, thus maintaining accuracy while improving efficiency.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system for authenticating digital contents includes a computing platform having a hardware processor and a memory storing a software code. According to one implementation, the hardware processor executes the software code to receive digital content, identify an image of a person depicted in the digital content, determine an ear shape parameter of the person depicted in the image, determine another biometric parameter of the person depicted in the image, and calculate a ratio of the ear shape parameter of the person depicted in the image to the biometric parameter of the person depicted in the image. The hardware processor is also configured to execute the software code to perform a comparison of the calculated ratio with a predetermined value, and determine whether the person depicted in the image is an authentic depiction of the person based on the comparison of the calculated ratio with the predetermined value.
