1. Abstract
Privacy-Preserving Healthcare Prediction is an AI-powered healthcare project designed to predict disease risks while protecting sensitive patient information. The system uses Machine Learning techniques and privacy-enhancing methods such as Federated Learning, data anonymization, and differential privacy to analyze healthcare data. It aims to support predictive healthcare analytics while reducing the need to share raw patient records across systems.
2. Objectives
- Predict disease risks using machine learning.
- Protect sensitive patient information during analysis.
- Implement privacy-preserving data-processing techniques.
- Explore Federated Learning for distributed model training.
- Reduce unauthorized access to healthcare data.
- Evaluate prediction performance and privacy trade-offs.
3. Existing System
Traditional healthcare prediction systems often centralize patient records for training and analysis.
Disadvantages
- Centralized data storage creates privacy risks.
- Sharing patient records may expose sensitive information.
- Data breaches can compromise confidential health information.
- Strict data-sharing restrictions can limit collaborative research.
- Anonymized data may still carry re-identification risks.
4. Proposed System
The proposed system combines disease prediction with privacy-enhancing techniques to minimize exposure of sensitive patient information.
Key features:
- Secure patient-data input and processing.
- Machine learning-based disease-risk prediction.
- Data anonymization and pseudonymization.
- Federated Learning simulation across multiple healthcare institutions.
- Differential privacy for selected training or analytics workflows.
- Model performance and privacy evaluation dashboard.
- Access controls and secure data handling.
- Downloadable prediction and evaluation reports.
5. Implementation Procedure
- Select an appropriate public healthcare dataset.
- Clean the data and handle missing values.
- Separate identifying information from model features.
- Apply suitable anonymization or pseudonymization techniques.
- Train a baseline disease-prediction model using Scikit-learn.
- Simulate multiple healthcare institutions using separate data partitions.
- Implement Federated Learning using a framework such as Flower.
- Explore differential privacy using an appropriate privacy library.
- Compare predictive performance with and without privacy-enhancing techniques.
- Evaluate privacy parameters and potential information leakage.
- Build a dashboard to display predictions and evaluation results.
- Test security controls and document privacy limitations.
