San Francisco, Sep 28: Facebook has admitted that the phone numbers that its users provide for security purposes are being used to target them with ads, the media reported.
"We use the information people provide to offer a better, more personalised experience on Facebook, including ads," a Facebook spokesperson was quoted as saying by TechCrunch on Thursday.
The social network specifically uses a phone number that users provide for two factor authentication (2FA) -- a security technique that provide a second layer of authentication to help keep accounts secure, the report added.
"We are clear about how we use the information we collect, including the contact information that people upload or add to their own accounts. You can manage and delete the contact information you've uploaded at any time," the Facebook spokesperson said.
Facebook confirmed the use of users' phone number for targeting ads after Gizmodo reported research work carried out by academics at two US universities who found that the social network uses pieces of personal information that individuals did not explicitly provide it to target them with ads.
Besides using the contact information users willingly provide to Facebook, it is also using contact information they handed over for security purposes and contact information they did not hand over at all, but that was collected from other people's contact books, the Gizmodo report said.
The findings of the study suggest that Facebook uses "shadow contact information" to make money through advertising.

Panaji (PTI): As part of a crackdown against tourist establishments violating laws and safety norms in the aftermath of the Arpora fire tragedy, Goa authorities on Saturday sealed a renowned club at Vagator and revoked the fire department NOC of another club.
Cafe CO2 Goa, located on a cliff overlooking the Arabian Sea at Vagator beach in North Goa, was sealed. The move came two days after Goya Club, also in Vagator, was shut down for alleged violations of rules.
Elsewhere, campaigning for local body polls, AAP leader Arvind Kejriwal said the fire incident at Birch by Romeo Lane nightclub at Arpora, which claimed 25 lives on December 6, happened because the BJP government in the state was corrupt.
An inspection of Cafe CO2 Goa by a state government-appointed team revealed that the establishment, with a seating capacity of 250, did not possess a no-objection certificate (NOC) of the Fire and Emergency Services Department. The club, which sits atop Ozrant Cliff, also did not have structural stability, the team found.
The Fire and Emergency Services on Saturday also revoked the NOC issued to Diaz Pool Club and Bar at Anjuna as the fire extinguishers installed in the establishment were found to be inadequate, said divisional fire officer Shripad Gawas.
A notice was issued to Nitin Wadhwa, the partner of the club, he said in the order.
Campaigning at Chimbel village near Panaji in support of his party's Zilla Panchayat election candidate, Aam Aadmi Party leader Kejriwal said the nightclub fire at Arpora happened because of the "corruption of the Pramod Sawant-led state government."
"Why this fire incident happened? I read in the newspapers that the nightclub had no occupancy certificate, no building licence, no excise licence, no construction licence or trade licence. The entire club was illegal but still it was going on," he said.
"How could it go on? Couldn't Pramod Sawant or anyone else see it? I was told that hafta (bribe) was being paid," the former Delhi chief minister said.
A person can not work without bribing officials in the coastal state, Kejriwal said, alleging that officers, MLAs and even ministers are accepting bribes.
