Recently, Facebook’s legal cell released a statement stating that Facebook scans almost all chat data to detect loose talks and criminal talks between two guys or groups of guys.
This came into limelight when Facebook informed police about a 40 year old guy whose chat-log showed that he was trying to have unfair relationship with a 13 year old teen in the US. Police caught the guy and he has been jailed.
Though, Facebook terms doesn’t state even a word in this regard but its been accepted by Facebook that there is system in place to filter such communication through Facebook chat.
Facebook also said that the chat-logs are scanned using a very efficient program. Also, the questionable chat-logs are manually checked by Facebook officials to ensure that correct talks are never marked as wrong/criminal to cause unnecessary problems for users.
The program primarily focuses on conversation between two Facebook friends who rarely chat, or have no mutual friends or live at geographically distant locations. Apart from this, the program also searches for slangs and phrases that’re uncommon in chats. These phrases are derived from English dictionary as well as from older Facebook chat record of criminals.
The program is near 100 percent effective for chating in English. For other languages, its still under development.
