Microsoft researchers purge Skype
Software King of the World Microsoft has worked out a way to cut down on fake accounts across Skype in a move which could kill off spammers in the network.
The AI method looks at sources including a user's profile, activities and social connections using what Vole dubs a supervised machine-learning environment that could automates the presently manual tasks of fraud detection.
So far, the results show the framework boosted fraud detection rates for particular account types by 68 percent with a five percent false positive rate.
According to a Volish report there are a few types of fraud relevant to Skype including, in particular, credit card fraud and other online payment fraud, as well as account abuse such as spam instant messages.
The idea of the system is to catch those fraudsters that elude the first line of defences at Skype.
Moises Goldszmidt, Yinglian Xie, Fang Yu, Martín Abadi of Microsoft Research and Anna Leontjeva of the University of Tartu, Estonia, conducted the research across 34,000 users that included a mix of legitimate and fraudulent accounts chosen from an initial randomised pool of 200,000 users that had not been blocked for more than four months since creating an account.
