RAPPOR is a novel privacy technology that allows inferring statistics about populations while preserving the privacy of individual users.
This repository contains simulation and analysis code in Python and R.
For a detailed description of the algorithms, see the paper and links below.
Feel free to send feedback to rappor-discuss@googlegroups.com.
Although the Python and R libraries should be portable to any platform, our end-to-end demo has only been tested on Linux.
If you don't have a Linux box handy, you can view the generated output.
To setup your enviroment there are some packages and R dependencies. There is a setup script to install them: $ ./setup.sh Then to build the native components run: $ ./build.sh This compiles and tests the fastrand C extension module for Python, which speeds up the simulation.
Finally to run the demo run: $ ./demo.sh
The demo strings together the Python and R code. It:
The output is written to _tmp/regtest/results.html, and can be opened with a browser.
R analysis (analysis/R):
Demo dependencies (demo.sh):
These are necessary if you want to test changes to the code.
Python client (client/python):
rappor.py file.Platform:
To run tests:
$ ./test.sh
This currently runs Python unit tests, lints Python source files, and runs R unit tests.
rappor.py is a tiny standalone Python file, and you can easily copy it into a Python program.
NOTE: Its interface is subject to change. We are in the demo stage now, but if there's demand, we will document and publish the interface.
The R interface is also subject to change.
The fastrand C module is optional. It‘s likely only useful for simulation of thousands of clients. It doesn’t use cryptographically strong randomness, and thus should not be used in production.
