Facebook CEO claims own data was shared by Cambridge Analytica

Admission underscores the problem Facebook has in persuading lawmakers that users can safeguard their own information

Mark Zuckerberg told lawmakers he was among the 87 million Facebook users whose data was improperly shared with a political consultancy, but rejected suggestions that users do not have enough control over their data on the world's largest social media network.

His admission that his own data made its way into the hands of Cambridge Analytica laid bare that even the company's technologically adept founder and chief executive was unable to protect his own information from parties seeking to exploit it.

That underscores the problem Facebook has in persuading lawmakers that users can safeguard their own information if they carefully manage their personal settings and that further legislation governing Facebook's use of data is unnecessary.

"Every time that someone chooses to share something on Facebook ... there is a control. Right there. Not buried in the settings somewhere but right there," the 33-year-old internet billionaire told the U.S. House of Representatives Energy and Commerce Committee.

Yet, when asked if his data had been improperly used, he replied: "Yes." He gave no further details.

The problem of data privacy dominated the hearing, which was more focussed and antagonistic than a hearing the day before in front of two Senate committees.

Wearing a dark suit and tie and prefacing almost every remark with "Congressman" or "Congresswoman," Zuckerberg appeared even more controlled than he did on Tuesday, as he refrained from cracking jokes and flashed few smiles.

"How can consumers have control over their data when Facebook does not have control over the data?" asked Representative Frank Pallone of New Jersey, the ranking Democrat on the Energy and Commerce committee, at the beginning of the hearing.

Zuckerberg repeatedly defended the company's practices, saying that users have control over their own data and decide what to share.

He said he was not familiar with so-called "shadow profiles," which media reports have described as collections of data about users that they have no knowledge of or control over. He also said Facebook does not collect information from users' verbal conversations through mobile devices' microphones.

However, in a series of questions on how people can remove data from Facebook, Zuckerberg said that Facebook does "collect data on people who are not signed up for Facebook for security purposes."

He had no response when asked how a person who is not a Facebook member can remove information without first signing up for the service.

Inevitable regulation?

Zuckerberg was on Capitol Hill for the second time in two days to answer questions about data privacy in the wake of revelations last month that millions of users' personal information was wrongly harvested from the website by Cambridge Analytica, a political consultancy that has counted U.S. President Donald Trump's election campaign among its clients.

The latest estimate of affected users is up to 87 million.

The data was improperly shared with Cambridge Analytica by an academic who gathered data on users and their friends through a questionnaire app on Facebook.

Facebook has since shut off the ability of apps to gather such data, but Zuckerberg said on Wednesday it will take "many months" to complete an audit of other apps to determine if they also improperly used data.

The House hearing followed a five-hour questioning by U.S. Senators on Tuesday, in which Zuckerberg made no further promises to support new legislation or change how the social network does business.

Facebook shares were up 1.5 per cent on Wednesday after dips earlier in the day. They posted their biggest daily gain in nearly two years on Tuesday as Zuckerberg managed to deter any specific discussion about new regulations that might hamper Facebook's ability to sell ads tailored to users' profiles.

"It is inevitable that there will need to be some regulation" of internet firms, Zuckerberg said on Wednesday, but he again steered away from any specifics.

Some lawmakers grew frustrated at their limit of four minutes each to press Zuckerberg on specifics, and chastised the billionaire at times for offering up rehearsed platitudes about valuing user privacy.

"I can't let you filibuster right now," Republican Representative Marsha Blackburn said at one point. She cut Zuckerberg off a number of times.

Bobby Rush, an Illinois Democratic congressman, was in the process of asking Zuckerberg when he learnt that Facebook allowed advertisers prevent ads from being shown to certain minority groups, a possible violation of civil rights laws. He was cut off.

“I am indeed wary that you are only acting now out of concern for your brand and are making changes that should have been made long ago,” said Democratic Representative Paul Tonko.
