信息来源：邪恶八进制信息安全团队（www.eviloctal.com）

The Internet is hemorrhaging unimaginable amounts of user data. In addition to information leaked through tracking cookies and spyware, users are often required to allow the providers of online services such as web-based email access to their data. We argue that it is possible to protect this information from the dangers of data mining by external sources regardless of the arbitrary privacy policies imposed by these services. As an existence proof, we present Ketu – an open-source, extensible tool that provides ormessage privacy and integrity while assuring plausible deniability for both the sender and receiver.
