Facebook had shared data with 52 firms, including Chinese companies: Report

Facebook has said that it shared user data with 52 companies, including Chinese firms, weeks after it was reported that the social media giant formed data-sharing partnerships with cellphone makers giving them access to details of users and even their friends. The social media giant's acknowledgement came as a part of a more than 700-page document dump to the US House Energy and Commerce Committee on Friday evening. The committee released the information publicly on Saturday, The Hill reported. Facebook yesterday revealed the partnerships shedding new light on its behaviour related to customer data in the wake of a scandal involving the British political consulting firm Cambridge Analytica where data of up to 87 million people was improperly shared, it said. The list featured major tech companies like Apple, Amazon, BlackBerry and Samsung. Other firms featured on the list include Alibaba, Qualcomm and Pantech. But the list also includes four Chinese firms that US intelligence has flagged as national security threats Huawei, Lenovo, Oppo and TCL. Facebook said it shared data with the companies in an effort to improve its integrations and user experience across platforms and devices, noting that its partnerships were established before smartphones running on Apple's and Google's high-powered operating systems were as ubiquitous as they are now, the report said.
