Facebook said on Wednesday that the number of users who post personal information to the Cambridge analytics company was 87 million, not 50 million.
It was updated at 6:40 p.m. Eastern time.
Personal information up to 87 million people – mostly in the United States – may be related to Cambridge analysis company “data analysis company” improper “sharing”, trump campaign data analysis using recently come under fire.
Mike Schroepfer, Facebook’s chief technology officer, published the figure at the end of a lengthy blog post outlining how the social media giant is trying to better protect user data.
Christopher Wylie, a former head of research at Cambridge analytics, previously said the company had access to more than 50 million users’ personal information.
The number of potentially affected users has risen sharply as Facebook scrutinizes data on how it protects or fails to protect its more than 2 billion users.
Meanwhile Mark zuckerberg, Facebook’s Mark CEO, confirmed Wednesday that he will testify before the house energy and commerce committee on data privacy issues.
Facebook is eager to show that it is trying to protect user information even before it has been neglected.
“It’s clear that we’re not doing enough,” zuckerberg told reporters on Wednesday. “We don’t pay enough attention to preventing abuse and thinking about how people use these tools to do harm.”
The damage includes “fake news, foreign election interference, hate speech, developers and data privacy,” zuckerberg said.
He added: “it is a huge mistake that we do not have enough extensive observation of our responsibilities.” Zuckerberg pointed out that it was his fault, but denied that he had any plans to step down as Facebook’s chief executive.
As to why Facebook now claim that there were 50 million men in a few weeks after the widely reported, 87 million people may have been affected, “zuckerberg said,” we’re just in the final in the past few days our understanding of the situation.
Last month, Wylie spoke to a number of media outlets and described his former employer, Cambridge Analytica, mining a large number of Facebook user data to try to steer voters on behalf of political clients.
“They want to fight a culture war in the United States,” Willie told the company’s leader, the New York times. “Cambridge analysis is seen as a weapons Arsenal against cultural warfare.”
Facebook admitted last month, Cambridge Analytica improperly visited about 270000 users of information, they downloaded by a professor of psychology at the university of Cambridge Aleksandr Kogan development application and user knowing friend’s information. Social media didn’t say how many people were affected, but said it was a platform policy for third-party access to user information.
Facebook said it learned of the violation in 2015 and was told that the data had been deleted, but it was later learned that the guarantees could be false.
Facebook’s mark zuckerberg will testify before congress on April 10 and 11.
Zuckerberg told reporters on Wednesday, Facebook requires and believes developers are protection information is not enough, “we actually need to make sure everyone in our ecosystem can protect people’s information.”
Facebook says it is for people to learn more transparent and the application of user interaction, including that users are more likely to see their Shared with the application of information, and allow the user to more easily remove application.
Another Facebook is taking measures: to delete a feature that allows users to enter a phone number or E-mail address to search for information, because “malicious actor also abuse these functions to scrape a public profile information”, Schroepfer says in his post.
“Given the scale and complexity of the activities we are seeing, we believe that most people on Facebook could undermine their public image in this way,” he said.
Schroepfer says there will be more changes in the coming months to better protect users’ Facebook messages.
“This is a big shift for us because we need to take more responsibility for the use of each tool,” zuckerberg said. “It’s going to take some time, and we’re committed to doing that.”
In the case of Cambridge analytics, it said it had removed all information received from the company led by Kogan, knowing that its search violated the terms of its service.
Cambridge analysts denied that any data “was used by Cambridge analytics as part of its service for Donald trump’s 2016 presidential campaign.”
