Some applications \u2013 primarily web browsers \u2013 now support private modes that aim to prevent sensitive information leaks. There are two problems with this application-level approach. First, there are many software engineering challenges in implementing correct and complete private modes. More fundamentally, applications cannot always tell which data is private \u2013 this is up to the user. As a result, applications that do support private modes may not implement the user\u2019s desired policy, and many other applications that process private data do not have a private mode at all, because the developers did not consider that use case.<\/div>\n<div><\/div>\n<div>In this paper, we present a case for private computing mode as a system service, rather than a per-application feature.
