Facebook used its apps to gather information about users and their friends, including some who had not signed up to the social network, reading their text messages, tracking their locations and accessing photos on their phones, a court case in California alleges.
The claims of what would amount to mass surveillance are part of a lawsuit brought against the company by the former startup Six4Three, listed in legal documents filed at the superior court in San Mateo as part of a court case that has been ongoing for more than two years.
A Facebook spokesperson said that Six4Three’s “claims have no merit, and we will continue to defend ourselves vigorously”. Facebook did not directly respond to questions about surveillance.
Documents filed in the court last week draw upon extensive confidential emails and messages between Facebook senior executives, which are currently sealed.
Facebook has deployed a feature of California law, designed to protect freedom of speech, to argue that the case should be dismissed. Six4Three is opposing that motion.
The allegations about surveillance appear in a January filing, the fifth amended complaint made by Six4Three. It alleges that Facebook used a range of methods, some adapted to the different phones that users carried, to collect information it could use for commercial purposes.
“Facebook continued to explore and implement ways to track users’ location, to track and read their texts, to access and record their microphones on their phones, to track and monitor their usage of competitive apps on their phones, and to track and monitor their calls,” one court document says.
But all details about the mass surveillance scheme have been redacted on Facebook’s request in Six4Three’s most recent filings. Facebook claims these are confidential business matters. It has until next Tuesday to submit a claim to the court for the documents to remain sealed from public view.
