(26 October 2011. New Scientist. )Known as the Facebook Immune System (FIS), the massive defense network appears to be successful: numbers released by the company this week show that less than 1 per cent of users experience spam.
The system is overseen by a team of 30 people, but it can learn in real time and is able to take action without checking with a human supervisor.
It took just three years for FIS to evolve from basic beginnings into an all-seeing set of algorithms that monitors every photo posted to the network, every status update– indeed, every click made by every one of the 800 million users. There are more than 25 billion of these "read and write actions" every day. At peak activity the system checks 650,000 actions a second.
The efficiencies of the virtual world are totally unprecedented in human history. The Matrix is turning out to be a very cool place.The only network bigger, Larus suspects, is the web itself. That makes Facebook's defense system one of the largest in existence.
