Understanding Differential Privacy
Differential privacy is a system for sharing information about a dataset by describing the patterns of groups within the dataset while withholding information about individuals. This technique ensures that the privacy of individuals is preserved, even when their data is included in the analysis.
Why Differential Privacy Matters in AI
In AI, the integrity and confidentiality of training data are critical. Differential privacy allows developers to use datasets that include personal information without compromising the privacy of individuals. By adding random noise to datasets or queries, it becomes difficult for external parties to pinpoint specific data entries linked to real-life individuals.
Applying Differential Privacy in AI Models
To implement differential privacy within AI models, specific methodologies, like adding noise to the gradients of the training process, are employed. This ensures that even if a model is breached, the probability of extracting original data points remains extremely low. These approaches help balance model accuracy and data privacy.
