A processor performance profiler is enabled to for identify specific instructions causing performance issues within a program being executed by a microprocessor through random sampling to find the worst-case offenders of a particular event type such as a cache miss or a branch mis-prediction. Tracking all instructions causing a particular event generates large data logs, creates performance penalties, and makes code analysis more difficult. However, by identifying and tracking the worst offenders within a random sample of events without having to hash all events results in smaller memory requirements for the performance profiler, lower performance impact while profiling, and decreased complexity to analyze the program to identify major performance issues, which, in turn, enables better optimization of the program in shorter developer time.

The present invention provides a new method of site and user authentication. This is achieved by creating a pop-up window on the user's PC that is in communication with a security server, and where this communication channel is separate from the communication between the user's browser and whichever web site they are at. A legitimate web site embeds code in the web page which communicates to the security server from the user's desktop. The security server checks the legitimacy of the'web site and then signals both the web page on the user's browser, as well as the pop-up window to which it has a separate channel. The security server also sends a random image to both the pop-up window and the browser. If user authentication is requested by the web site the user is first authenticated by the security server for instance by out of band authentication. Then the security server computes a one time password based on a secret it shares with the web site and sends it to the pop up window. The user copies this one time password into their browser which sends it to the web site, which can re-compute the one time password to authenticate the user.
