ppAURORA aims to compute the area under curve (AUC). In this study, we use ppAURORA to compute the AUC of the receiver operating characteristic (ROC) curve (AUROC) and precision-recall (PR) curve (AUPR). ppAURORA is based on a 3-party computation framework, called CECILIA, which offers a variety of building blocks to facilitate more complex algorithms in a privacy preserving manner. The project is implemented in C++.
No installation is required.
We strongly recommend using cmake to compile the project. To manually compile the project, the followings should help.

./proxy_<auc_type> role <port of proxy 1> <ip of proxy 1> <port of helper> <ip of helper> <delta> <input>- auc_type = auroc, auroc_tie or aupr
- input = #input parties,#samples of the first input party,#samples of the second input party,...,#samples of the last input party
- delta = delta is a number that specifies how many selections are made after shuffling
Example run for AUROC no-tie is as follows:
./helper "127.0.0.1" 7777
./proxy_auroc 0 8888 "127.0.0.1" 7777 "127.0.0.1" 10 "8,1000,1000,1000,1000,1000,1000,1000,1000"
./proxy_auroc 1 8888 "127.0.0.1" 7777 "127.0.0.1" 10 "8,1000,1000,1000,1000,1000,1000,1000,1000"In order to run the scalability analysis, one can use the corresponding scripts in exp_runners.sh folder. To run all the experiments at once, all_exp.sh file can be run.
