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.

Hyderabad: A 22-year-old woman committed suicide in Hyderabad about a month after a relative allegedly injected her with HIV-infected blood after she rejected a marriage proposal, police said.
The woman is identified as Ramani. She was found dead at her grandmother's home in Annojiguda on Friday morning, according to The News Minute.
According to police, the accused, a 24-year-old man related to the victim, had been in a relationship with her. Initially their families had agreed to their marriage but the proposal was later withdrawn after medical tests confirmed that the man was HIV positive.
According to investigators, the accused allegedly injected his own blood into the woman at her home on March 11, after his marriage proposal was refused. Police said he obtained a syringe and committed the act when she was alone, allegedly with the intent of forcing her into marriage.
The incident was discovered when the woman told her relatives and was sent to a medical checkup. The accused was detained in March and put in judicial prison on allegations including attempted murder.
Police said a suicide note was recovered from the scene in which the woman mentioned being distressed by the manner in which the incident was discussed on social media. Family members stated that she had been undergoing emotional distress and had developed health complications following the assault.
