Editing Cheating in online games (section)

===Pattern detection===
Pattern detection systems scan the player's hard drives and system memory for known cheat code or programs. Compared to statistical detection the key advantage is that also the subtle cheaters are detected. Other than this, a pure pattern detection approach generally has few advantages. Experience has shown that keeping detection-based systems up to date is relatively slow and labor-intensive as one needs to constantly track down cheats and update detection patterns. End–users may also be concerned with privacy issues, such as has been the case with VAC (Valve Anti-Cheat) accessing browsing history.<ref>{{cite journal |url=http://www.pcgamesn.com/counterstrike/gabe-takes-reddit-clear-valve-anti-cheat-rumours-do-we-send-your-browsing-history-valve-no |title=Gabe takes to Reddit to clear up Valve Anti-Cheat rumours; "Do we send your browsing history to Valve?
