Hardware Anti-Cheat and Wireless Radios

Hardware Anti-Cheat Technology

One of the more interesting non-multi-core projects that was being demonstrated was a rather ingenious new solution to preventing certain forms of cheating in online games. As with most of the projects on show, this is purely at the research level and was running completely in a software environment but eventually it would be implemented in hardware.

The system uses two parts, a client/server communications component and a keyboard and mouse detection part. The game also needs to be cooperative in the scheme for it to work.

The way it works is theoretically very simple; the chipset records all input from the keyboard and mouse, and the game does likewise. The two are then compared and if a discrepancy is found the assumption is you must be cheating - by using a script to add in keyboard and mouse commands. The chipset then relays this information to the server for it to act upon. Of course, this doesn't stop wallhacks and such like but a vast number of cheats could be prevented.

Another potential use for this technology is in preventing or at least detecting click fraud as well as protecting against other malware that emulates input. The only trouble being that as this would be a standard hardware solution it would be vulnerable to a standard workaround. And with big money to be made in fraudulent activities, it probably wouldn't be long before this happens.

Multi Protocol Wireless Adapter

With more and more focus being put on mobile devices and connectivity on the move, there are an increasing number of wireless signals being bounced around the atmosphere. This can get a bit messy and lead to interference between one connection and another - try putting your mobile phone next to your laptop while you're using WiFi. To combat this Intel has been working on a way to integrate multiple wireless networking standards onto a single chip that can switch between them on the fly. This means WiFi, 3G, Bluetooth, WiMax (when it finally appears) will all be able to coexist an a single device without any interference.

As well as enabling more intelligent use of the precious radio wave spectrum, the single chip solution will be more power efficient and weigh less than a multi chip solution. All of which is rather encouraging.

To enable this system to be shrunk down to fit on mobile devices, Intel is also working on an antenna that can change shape in accordance with the changing protocols. This sounds more sophisticated than it actually is as all they're doing is switching between different arrangements of wires that are shaped like the different antennae used by the various wireless methods. Still pretty cool though. If this ever comes to fruition it will be a big step forward.
