Facebook is official blog on April 4, 2018 local timePublish statementThen we announced the latest situation on data fraud use problem and handling future user data. Among them, Facebook's Mike Shuferfer CTO (Chief Technology Officer) clearly announces a plan to set up a system to halt leakage of user data by making the following modifications to nine functions on Facebook I am doing it.

· Events API:Disabling browsing of user's event participation information from external application
· Groups API:Access to private group from external application is made by Facebook and administrator approval system and member list is hidden etc.
· Pages API:Changed the Pages API that allowed users access to posts to Facebook approval system
· Facebook login:You can log in with Facebook account on apps and services "Facebook login" strictly and check in and likes, access to personal information such as photos, posted contents etc. is changed to Facebook approval system
· Instagram Platform API:The Instagram Platform API which was used conventionally is abolished. (Instagram Graph API provided instead)
· Search and Account Recovery:Abolished the search function by telephone number or e-mail address. We also made changes to account recovery to reduce the risk of scraping.
· Call and text message history:Deleting log data older than 1 year, with the Facebook Lite application for Android and Messenger application acquiring call history and text message history. In future it is impossible to obtain unnecessary data such as talk time.
· Data Providers and Partner Categories:Discontinue "partner category" targeting advertisements based on user information
· App Controls:From around April 9 (Monday), displays the applications that are linked to the top of the news feed. If you do not want an application you can delete it yourself.


In addition, this blog also shows that there are possibilities that Cambridge Analytica may have 87 million people illegally using personal information. Also, about 80% of it is occupied by American citizens.


Mr. Zuckerberg has held a telephone conference on this matter, and if you have set up search by telephone number and e-mail address to "Everyone" in Facebook's personal settings so far, that person will not be in a way anyway other than friends and acquaintances We are acknowledging that there is a high possibility that information was being accessed from third parties. This setting defaults to "Everyone", so it seems that most of Facebook users, the total of 2 billion people, will be applicable, unless you change your settings yourself.


Also in the press conference, Mr. Zuckerberg said he felt the responsibility for his mistakes made by his company and said he would like to continue further progress with the lessons learned here. In addition, Mr. Zuckerberg, who was asked by reporters "I am confident that it is the best man to operate a company," he replied "I am confident" and denied resignation.
