Homomorphic PCA

This repository focuses on performing PCA on encrypted data. It uses CKKS homomorphic scheme to perform computations on encrypted data. To use this repository, clone the repo and type :-

cd Homomorphic_PCA
python3 pca.py

For implementing CKKS homomorphic scheme, we have used SEAL-Python(python binding for the Microsoft SEAL library) Dependencies required for this repository are:-

• Seal-Python
• PIL
• sklearn

The read_data.py file supports reading of 7 datasets that were used for experimentation. The Yale face dataset has been provided in the repository. Other datasets that are supported are:-

• Parkinsons Telemonitoring
• Air Quality
• Wine Quality(both red and white)
• MNIST
• Fashion-MNIST
