If you used Facebook, other people could know about your information.

The possibility has been raised that Facebook could leak up to 2.2 billion personal information.



You may already know. Facebook is the largest social networking site in the world. 


Recently, personal information was leaked due to security concerns. But the damage is known to be very serious. 


There is a lot of attention on how Facebook handles this issue.

Facebook said it is likely that almost all Facebook users ' public profile information was collected through third-party scrapers using a user search feature based on phone numbers and email addresses for finding friends. 


The next Web site estimated the size at about 2.2 billion.
(2,200,000,000)






Facebook has said it will remove the ability to search for users using phone numbers and email addresses to prevent such leakage, 
while preventing people from posting third-party apps installed on Facebook on its event page.







Facebook, on the other hand, 
is estimated to have leaked personal information on Cambridge Analitica (CA), 

which had previously been estimated at 50 million people, 
and to have reached 87 million users due to its leakage of telephone numbers and e-mail addresses.
