2. Drone Collision Avoidance

io.github.andrewquijano » drone-collision-avoidanceMIT

This library provides a secure drone collision avoidance system using homomorphic encryption. It uses encrypted GPS coordinates to compute paths and avoid collisions without revealing sensitive location data. For now, to avoid collision, a drone changes altitude to avoid collision with another drone as it knows the path segment of collision

5. Level Site Ppdt

io.github.andrewquijano » level-site-ppdtMIT

This JAR file is used for implementing the Level-Site Privacy-Preserving Decision Trees (PPDT). See the paper "Enhanced Outsourced and Secure Inference for Tall Sparse Decision Trees" which describes the implementation and performance gains this approach has in avoiding the conversion to a complete binary tree as in the Joye and Salehi paper.
