Open Hiwi Positions
Implementing Privacy-Preserving Machine Learning Protocols
We are looking for a motivated Hiwi. The number of working hours is flexible and ranges from 40 to 82 hours per month starting as soon as possible.
Motivation & Goal
Several useful services that use machine learning (ML) algorithms to categorize and classify large amounts of sensitive data have emerged in the recent past. However, in order to use these services, current solutions require the disclosure of personal information. As a result, there is an inherent conflict between utility and privacy: ML requires data to operate, whereas privacy requires sensitive information to be kept private. This sparked the field of Privacy-Preserving Machine Learning (PPML), which ensures data privacy. The goal of the position is to work on PPML challenges such as:
- Design and implementation of a PPML protocol for various settings using Secure multi-party computation (MPC). The settings include two, three and four server cases as well as passive and active security models.
- Implementation of the designed PPML framework (consisting of model training and inference) in C/C++ using the MOTION framework .
- Comparisons with state-of-the-art ML models in plaintext primarily using the PyTorch framework.
The results emerging from this work are essential contributions to research papers that will be published at international top conferences.
