Program Code – Project: SocInf Membership Inference Attacks on Social Media Health Data with Machine Learning

Certainly! Let’s dive into creating a simplified Python program that simulates a basic framework for SocInf: Membership Inference Attacks on Social Media Health Data with Machine Learning.

In this project, we’ll generate a mock dataset, symbolizing individuals’ health data collected from a social media platform. We’ll then train a membership inference attack model to determine whether an individual’s data was used in training the health prediction model or not. This script will use scikit-learn for machine learning parts.

# Generate a mock dataset: Health data features and their binary health outcomes
X, y = make_classification(n_samples=1000, n_features=20, n_classes=2, random_state=42)

# Splitting the dataset into training and testing sets (50% each)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.5, random_state=42)

# Training a simple health prediction model using Random Forest
health_model = RandomForestClassifier(n_estimators=100, random_state=42)
health_model.fit(X_train, y_train)

# Generating the shadow dataset for training the attack model
X_shadow, y_shadow = make_classification(n_samples=1000, n_features=20, n_classes=2, random_state=24)
X_shadow_train, X_shadow_out, y_shadow_train, y_shadow_out = train_test_split(X_shadow, y_shadow, test_size=0.5, random_state=42)

# Training the same model with shadow dataset
shadow_model = RandomForestClassifier(n_estimators=100, random_state=42)
shadow_model.fit(X_shadow_train, y_shadow_train)

# Infer membership: Assuming if a data point has a high confidence score, it was part of the training set.
train_predictions = shadow_model.predict_proba(X_shadow_train)
out_predictions = shadow_model.predict_proba(X_shadow_out)

# Creating labels for membership inference (1 if in training set, 0 if not)
y_shadow_train_label = np.ones(len(X_shadow_train))

‘Attack Model Accuracy: XX.XX%’

The actual accuracy will vary based on the randomness in data generation and model initializations.

Code Explanation:

This Python program embarks on a project titled ‘SocInf: Membership Inference Attacks on Social Media Health Data with Machine Learning’. Here is the step-by-step logic and architecture of the program:

1. Data Generation: We start by creating a mock dataset representing health data using make_classification. This dataset consists of basic features (attributes) and binary outcomes (healthy or not).
2. Train/Test Split for Health Prediction Model: We split our dataset into training and testing sets, ensuring our health prediction model has unseen data to validate its performance.
3. Training the Health Prediction Model: A RandomForestClassifier model is trained on the health data. This model simulates the target of a membership inference attack, aiming to predict health outcomes based on features.
4. Shadow Dataset Generation: To train our attack model, we generate a shadow dataset. The shadow model, trained on this dataset, is used to infer whether data was part of the original training set or not.
5. Training Shadow Model: Mimicking the health prediction model, the shadow model is trained to provide the basis for attack model training.
6. Infer Membership with Shadow Model: By comparing model confidence scores on training versus out-of-training data, we simulate the logic behind inferring membership in the dataset.
7. Attack Model Training: This model is trained on the outputs of the shadow model, learning to differentiate between data that was in the training set and data that wasn’t.
8. Evaluating the Attack Model: Finally, we evaluate our attack model’s accuracy using the original model’s predictions on unseen test data and shadow model predictions. The goal is to determine the model’s ability to correctly infer membership, demonstrating the potential vulnerability in the health prediction model.

This script encapsulates a simplified architecture of a membership inference attack, focusing on understanding data vulnerabilities in machine learning models, particularly those handling sensitive health data from social media.
