BakingTimer: Privacy Analysis ofServer-Side Request Processing Time

In Proceedings of the 35th Annual Computer Security Applications Conference (ACSAC 2019)
We propose a new history sniffing technique based on timing the execution of server-side request processing code. This method is capable of retrieving partial or complete user browsing history, and it does not require any permission.
