Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for matching multimedia user data to stored data often fail to protect user privacy and prevent bias in generating video avatars.
Innovation Solution
A system and method that utilizes a processor to receive user data, validate user identity, and generate a video avatar by training a machine-learning model with user data and video avatar training data, including extracting user data items and incorporating video elements, to create a personalized video representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user data is collected and processed to generate video avatars, then the personalization and accuracy of video avatars is improved, but user privacy is compromised
Solution Approach 1:
The system extracts only the essential features needed for avatar generation from user data, separating the necessary biometric information from sensitive personal data. This extraction process removes unnecessary personal identifiers while retaining the core characteristics needed for accurate avatar creation, thus improving privacy protection while maintaining avatar accuracy.
Solution Approach 2:
The patent introduces an intermediary processing layer that transforms raw user data into anonymized feature representations. This intermediary step acts as a buffer between the user's raw data and the avatar generation system, ensuring that sensitive information is not directly stored or processed in a usable form, thereby protecting privacy while enabling accurate avatar generation through transformed features.
2Measurement precision
If machine learning models are trained with extensive user data, then the quality and realism of video avatars is improved, but bias in the generated avatars increases
Solution Approach 1:
The system applies different processing and validation rules to different types of user data based on their sensitivity and potential for bias. Sensitive attributes receive additional scrutiny and transformation, while neutral attributes are processed more directly. This localized quality control ensures that bias-prone data receives special attention during processing, reducing overall bias while maintaining high avatar quality through appropriate data handling.
Solution Approach 2:
The patent implements preliminary data validation, cleaning, and bias detection before the data is used for model training. This preliminary action includes checking for representational balance, removing biased patterns, and ensuring diverse coverage across different user groups. By addressing bias issues before training begins, the system can achieve high avatar quality without inheriting biases from the training data.
