Facebook admits it shared users’ phone numbers for ads

San Francisco, Sept 29: Facebook on Thursday confirmed that advertisers were privy to phone numbers given by members of the social network for enhanced security.

A study by two US universities, first reported by news website Gizmodo, found that phone numbers given to Facebook for two-factor authentication were also used to target advertising.

Two-factor authentication is intended to enhance security by requiring a second step, such as entering codes sent via text messages, as well as passwords to get into accounts.

Phone numbers added to profiles, for security purposes, or for messaging were potential fodder for advertisers, according to the study.

"These findings hold despite all the relevant privacy controls on our test accounts being set to their most private settings," researchers said in the study, which looked at ways advertisers can get personally identifying information (PII) from Facebook or its WhatsApp and Messenger services.

Contact lists uploaded to Facebook platforms could be mined for personal information, meaning that people could unintentionally help advertisers target their friends.

"Most worrisome, we found that phone numbers uploaded as part of syncing contacts - that were never owned by a user and never listed on their account - were in fact used to enable PII-based advertising," researchers said in the study.

The study supported concerns that Facebook uses "shadow" sources of data not given to the social network for the purpose of sharing to make money on advertising.

"We use the information people provide to offer a better, more personalised experience on Facebook, including ads," a spokeswoman said in response to an AFP inquiry about the study findings.

"We are clear about how we use the information we collect, including the contact information that people upload or add to their own accounts."

Facebook is grappling with the worst crisis in its history, vilified for not more zealously guarding the information that users share.

The Silicon Valley-based internet colossus faced intense global scrutiny over the mass harvesting of personal data by Cambridge Analytica, a British political consultancy that worked for Donald Trump's 2016 election campaign.

The company has admitted up to 87 million users may have had their data hijacked in the scandal.

Mangaluru, Nov 30: A 22-year-old college student succumbed to her injuries at a private hospital in Mangaluru today, days after she was hit by a goods tempo while crossing a road in Padubidri.

The deceased has been identified as Preksha, a resident of Nadsalu Billitota in Padubidri. The fatal incident occurred as Preksha, who was returning home after completing her examination, attempted to cross the service road towards Mangaluru. She was struck by a goods tempo approaching from the Udupi side, causing her to fall and sustain a severe head injury.

Prompt action from local residents ensured she received immediate first aid before being rushed to a hospital in Mangaluru for specialised treatment. Despite medical efforts, she passed away while undergoing care.

Preksha was a student at Karavali College, Vamanjoor on the outskirts of Mangaluru city. The tragedy is compounded by the fact that she belonged to a financially vulnerable family, having previously lost her father. She is survived by her mother and brother.

A case related to the accident has been registered at the Padubidri police station, and an investigation is underway to determine the exact circumstances that led to the collision. The incident highlights the growing concerns over road safety, particularly on busy service roads, and serves as a tragic reminder of the human cost of traffic accidents.

Bengaluru: The Vokkaligara Sangha on Thursday issued a stern warning to the Congress, saying the party could face serious electoral repercussions if Deputy Chief Minister D.K. Shivakumar is not appointed as Chief Minister.

The warning follows the public backing of Shivakumar’s chief ministerial ambition by top Vokkaliga pontiff Nirmalanandanatha Swami, who urged the Congress high command to honor his claim.

“The community supported Congress in the 2023 Assembly elections only because Shivakumar had a real chance to become CM. If he is cheated, we’ll teach the party a big lesson,” said newly elected Sangha president L. Srinivas. He added that Vokkaligas would organize protests under the guidance of community leaders.

General Secretary C.G. Gangadhar pointed out that Congress won more seats in the Vokkaliga-dominated Old Mysuru region due to Shivakumar’s influence, adding, “If Congress wants to retain power, Shivakumar should be made the CM.”

Outgoing president Kenchappa Gowda emphasized Shivakumar’s contribution to Congress’ victory. “Our community voted for Congress thinking he would become CM. Siddaramaiah has also served the party well, but Shivakumar should now be given a chance,” he said.

Former general-secretary Konappa Reddy appealed to Sonia and Rahul Gandhi to recognize Shivakumar’s loyalty and service, saying, “Congress is known to keep its promises. We hope it won’t break the promise made to him.”

New Delhi: Karnataka chief minister Siddaramaiah and deputy CM DK Shivakumar on Saturday put up a dramatic display of unity at a closely watched joint press briefing, firmly dismissing weeks of speculation about a power-sharing tussle within the Congress. With the high command nudging both leaders to sit together and settle the dust, the meeting became a political spectacle, ending with the duo declaring that there was “no confusion, no differences.”

Calling the reports of a rift “manufactured confusion,” Siddaramaiah said the talks had gone smoothly, even joking about their breakfast. “Breakfast was very good. All three of us enjoyed it,” he said. “We want to end this confusion once and for all. For local elections and for 2028, our mission is clear — Congress must return to power. There is no difference between me and DKS, not now, not before.”

He blamed the media for fuelling rumours and reiterated absolute adherence to the party leadership. “From tomorrow, let there be no confusion. What the high command says, we will follow.”

Siddaramaiah also assured that the Assembly session starting December 8 would run smoothly and vowed that Congress would take on the BJP and JD(S) “together.”

Shivakumar echoed the chief minister word for word, stressing loyalty and discipline. “People have given us a massive mandate. It is our duty to deliver,” he said. “This government was formed under Siddaramaiah’s leadership. We both have complete trust in the high command. If they tell me to wait, I will wait.”

He added that the two leaders had discussed strategy for the 2028 Assembly elections. “Whatever the CM says, I agree. We are loyal soldiers of the party. The party may be facing challenges nationally, but we will keep it strong in Karnataka.”

Shivakumar also said Siddaramaiah would soon visit his home for lunch or dinner — another symbolic gesture meant to underline their unity.

Both leaders later posted on social media describing the breakfast meeting as “productive” and focused on “Karnataka’s priorities.”

The BJP, however, rejected the show of camaraderie as “pure bunkum,” accusing Congress of trying to paper over an internal power struggle. But Siddaramaiah and Shivakumar insisted their united front would continue — and that there was “no confusion” within the state leadership.
