How tagging your location on Instagram could be used for surveillance

Elamin Abdelmahmoud is Buzzfeed's social media editor and q's online columnist. Every couple of weeks, he brings us up to speed on the big headlines taking over the internet right now.

This week, he joins host Tom Power to talk about location tagging on Instagram. On the surface, it seems harmless, but this week, an investigation published by Buzzfeed News revealed that the combination of ubiquitous public cameras and social media data trails has made it incredibly easy to identify individuals and their movements.

They reported that by cross-referencing just one hour of video footage from public webcams with Instagram stories taken and shared in Times Square, they were able to confirm the full identities of a half dozen people.

Abdelmahmoud tells us more about how private we can expect our online tools to be.
