There has been a big allegation that Facebook has failed to protect its users' personal information. UK election consultancy firm Cambridge Analytta has criticized Facebook for utilizing Facebook data in the US elections. There has been a complaint, Facebook has been collecting information on phone calls and SMS from Android phones without user's consent for a long time.
In response to a report by Ars Techniker, Facebook completely denied the incident. Facebook has said in a statement that Facebook has collected as much information as the user allows.
Facebook has apologized for publishing advertisements in the magazine on the issue of Facebook infiltration by Cambridge analytics. "It's our responsibility to protect your information," said Zuckerberg's signature advertisement. If we can not do that, we can not fulfill our responsibility fully. '
Meanwhile, in the context of collecting calls and SMS data, Facebook has said that users have to give permission to provide information about messenger or Facebook lights. They can stop this feature at any time. Apart from this, any call or text information in the app can be deleted.
