SAN FRANCISCO: Facebook can determine where users are even if they opt out of having their whereabouts tracked.
The company revealed in a letter sent to two US senators requesting information. Facebook explained ways it can still figure out where people are after they have selected not to share precise location data.
The social network agreed that knowing a user’s whereabouts as benefits ranging from showing ads for nearby shops to fighting hackers and battling misinformation.
“There is no opting out. No control over your personal information,” Republican Senator Josh Hawley said in a tweet. “That’s Big Tech. And that’s why Congress needs to take action.”
Facebook said that clues for figuring out a user’s location include being tagged in a photo at a specific place or a check-in at a location such as at a restaurant during a dinner with friends.
People may share an address for purchases at a shopping section at Facebook, or simply include it in their profile information. The company can also share whereabouts from devices connecting to the internet are given IP addresses, along with location information shared in posts by users,
Those addresses include locations, albeit a bit imprecise when it comes to mobile devices linking through telecom services that might only note a town or city.
Facebook said knowing a user’s general location helps it and other internet firms protect accounts by detecting when suspicious login behaviour occurs. For example, there may be activity by someone in South America when a user lives in Europe.
IP addresses also help companies battle misinformation by showing the general origin of potentially nefarious activity, such as politically oriented posts be aimed at a particular country.
Facebook said recently that it is ready for a data privacy law that is to go into effect in its home state of California at the start of next year. The California Consumer Privacy Act (CCPA) will give internet users the right to see what data big tech companies collect and with whom it is shared.
