The guy who injected himself with a computer virus is Dr Mark Gasson from the University of Reading. He had a chip inserted in his hand which was then infected with a virus. (He wasn't content with just sewing it into his jacket).
The device, which enables him to pass through security doors and activate his mobile phone, is a sophisticated version of ID chips used to tag pets.
In trials, Dr Gasson showed that the chip was able to pass on the computer virus to external control systems.
If other implanted chips had then connected to the system they too would have been corrupted, he said.
This takes the possibility of cyber terrorist attacks to a whole new level. People wanting to reek havoc with computer or RFID systems can possibly do so virtually undetected. Viruses could be able to be transferred from the virus laden chip to the target computer system that reads the chip - unless the system is protected in some way. Someone with the knowledge of computer hacking through these types of chips and the devices that read them, can do damage in an airport or a bank or any other place of commerce, and can really screw up an entire computer network quite easily.
Reading University, in England, is also home to the "Reverse Pinocchio" - Kevin Warwick - who wants to be a Cyborg so badly that he continues to add Borg-like parts to himself.
Personally, I think this whole thing is entirely creepy.
But it's one less thing the Amish have to worry about.
