Differential Privacy at Snapchat

At Snap, privacy is a central part of our product philosophy. We want Snapchatters to feel safe and secure interacting with their friends and exploring the world around them without worrying about the privacy of their data. To achieve this goal one of the tools we use is Differential Privacy (DP), the de facto privacy standard in both industry and academia. In this article, first we summarize some of the privacy concerns that Snap and the industry as a whole face. Then we examine how Snap uses DP to address those concerns regarding friend recommendations and Maps features.
