OpenDP is an open-source software library for differential privacy, a mathematical framework that protects individuals when statistics are published from sensitive data. The library provides privacy-preserving methods for statistical analysis, aimed at researchers and data custodians who need to publish results from confidential sources. The project describes itself as a community effort to build trustworthy open-source tools, and it publishes new versions on its website and in its GitHub repository.
The project sits within Harvard University: copyright and the website belong to The President and Fellows of Harvard College, based in Cambridge, Massachusetts, United States. The code is released under the MIT licence and runs on your own infrastructure, so sensitive data does not need to be sent to a service. The website does not describe a hosted offering. For European organisations, OpenDP is a transparent tool for privacy engineering that they operate themselves, although its institutional home is in the United States.
