NEW YORK/SAN FRANCISCO: Facebook Inc is buying a software firm that specialises in authenticating government-issued identification cards, the two companies said on Jan 23, a step that may help the social media company learn more about the people who buy ads on its network.
US lawmakers have expressed alarm at Facebook's limited ability to know who is buying advertisements, including election-related ads, on the world's largest social network.
