Privacy-preserving Linear Models over Homomorphically Encrypted Data

The data involved in machine learning are often confidential as, eg. medical or federal data. The security and authenticity of such data sets needs to be guaranteed. In this thesis we implement logistic and linear regression using the homomorphic Fan-Vercauteren encryption scheme to tackle this problem. Homomorphic encryption allows us to make predictions on the encrypted data without decrypting it. We then examine the feasibility and runtime performance of our implementation.
