1. Android wallpaper fingerprints
  
  Uniquely identifying users so that they can be tracked as they go about their business on the internet is, sadly, a major goal for advertisers and others today. Web browser cookies provide a fairly well-known avenue for tracking users as they traverse various web sites, but mobile apps are not browsers, so that mechanism is not available. As it turns out, though, there are ways to "fingerprint" Android devices—and likely those of other mobile platforms—so that the device owners can be tracked as they hop between their apps.
