What is Model Inversion Attack?
Model Inversion Attack is a sophisticated privacy attack where adversaries reconstruct training data from machine learning models by analyzing model outputs, gradients, or parameters. This attack can expose sensitive information that was used to train the model.
Attack Process
- Query model with carefully crafted inputs
- Analyze model outputs and confidence scores
- Use gradient information when available
- Reconstruct training data through optimization
Privacy Risks
- Personal information exposure
- Proprietary data reconstruction
- Medical or financial record leakage
- Intellectual property theft
