A Study of Event Frequency Profiling with Differential Privacy

This directory contains the code for the static analysis and randomization described in the paper. Below are the folders that contain essential code and results:

• common contains the common utility classes and the Matlab code
• gator contains the code for the analysis to find “<=” pairs
• le-pairs-csv contains the “<=” pairs
• randomized-response* contain the code for the randomization

Run

Clone the repository:

$ git clone https://github.com/presto-osu/cc20.git
$ cd cc20

To run the analysis, download and extract apks.tar.gz to cc20/apks and execute the commands:

$ cd code
$ bash runall_gator.sh
$ python process_le_pairs.py

To run the randomization, download and extract dataset.tar.gz to cc20/dataset and execute the following commands:

$ mkdir log
$ bash runall_experiments.sh

The log files are stored in folder log.
