When iOS 8 came out Apple announced a MAC addresses randomization feature to prevent device scanners like this one. But after people tested the feature it turned out that the scheme only works under a very narrow set of conditions that makes it nearly useless. I haven't heard if this has changed in 8.1 or 8.2 but hopefully Apple will move to stop these shenanigans, as well as Google's Android.
- dublinben 12y agoUntil that happens, you can prevent this kind of tracking by turning your WiFi radio off. For battery life purposes, it's wise to do this anyway when you're not in a location where you intend to be using the WiFi connection.
- walterbell 12y agoAre there any local-only contextual apps which can turn wifi on or off based on GPS location?

- cesarb 12y agoI like Wi-Fi Matic (https://sites.google.com/site/wifimaticapp/ https://sites.google.com/site/wifimaticapp/). It uses the phone network cell identifiers instead of GPS (so it works even where you can't get a GPS fix), and auto-learns the cell identifiers which can be seen in the range of your wifi networks. And its source code is available (I originally found it on f-droid).
- shpx 12y agothanks, installed.
- acdha 12y agoIt doesn't look like MAC randomization is relevant to this scenario unless you're cycling the device on and off the network while you're waiting in line. What it would do is prevent them from tracking you at different locations or trips, although obviously the TSA & airlines still know you were there.
