 # SIG Introduction
 
-AI Security SIG focuses on security issues in AI model development projects from data processing, model training, and deployment inference. The details are as follows:
+AI Security SIG focus on model security and data privacy protection in the field of artificial intelligence, mainly including the following directions:
+:
 
-1. **AI Model's robustness and reliability**: Inference robustness to adversarial samples or natural perturbation samples. Data concept drift detection and model fault injection.
-2. **Privacy protection**: Differential privacy training and federated learning.
+1. **AI Model's robustness and reliability**: Adversarial samples, adversarial training, explainable AI, data concept drift detection and model fault injection.
+2. **Privacy protection**: Differential privacy training, federated learning, data masking, privacy-leakage evaluation.
