> [Disruptive Digita] is also looking into technology that would let Facebook deliver personalized ads based on targeting data stored on the user’s device, meaning Facebook wouldn’t need to access it.
Anyone know how this would work? My spidey-sense is tingling here at the thought of apps scanning data on my phone!
My idea? FB app stores data locally, uses this local data to pull ads onto your phone to be served/rendered. Don't need to send user data out. Just identify the ads this phone should be targeted by and render them as needed.
Good point about the scanning, though. These scumbags certainly would try to pull something like that off.
probably just like google's federated learning of cohorts thing.
they still cluster you, but instead of collecting your browsing activity from partner websites, they do it locally using browser history that doesn't leave your device, and the net effect is that you have an equivalent of a browser cookie or additional http request header that doesn't identify you, but does identify your cluster memberships.
some people are still not ok with this, i'm on the fence.
