Google differential privacy technology, used in Chrome, starting in 2014: http://www.computerworld.com/article/2841954/googles-rappor-aims-to-preserve-privacy-while-snaring-software-stats.html http://www.computerworld.com/article/2841954/googles-rappor-... https://github.com/google/rappor https://github.com/google/rappor https://arxiv.org/abs/1407.6981 https://arxiv.org/abs/1407.6981 (I worked on this) I don't see any mention in the article of what algorithms Apple is using, or a link to the code. In the area of privacy, the code should really be open source, for obvious reasons.
