The algorithm searches for phrases obtained previously in chats criminals, including those involved in sexual abuse. The Reuters reported on Thursday (12) a success. A 30 year old man was talking about sex and arranged a meeting with a girl of 13 years. The system automatically sent the Facebook chat history on Facebook officials, who analyzed the conversation and called the police immediately. The criminal was arrested the next day.
Some people should not to like the idea of having read your chats, but Facebook's security director, Joe Sullivan, said that only a small part of the conversation is accompanied by humans. "We never wanted to create an environment where we have employees watching private conversations, so it's very important we use a technology that has a small rate of false positives," he said.
The system focuses specifically on conversations between users who do not have as strong a relationship on Facebook. People who do not speak often have significant differences in age or live far apart, for example, receive special attention and have more chances of getting caught by the algorithm.
The story is controversial. While some believe that monitoring can inhibit the activity of criminals, others argue that a private conversation between two people need to be particular.
