People are creatures of habit. This applies to daily routines, but also to small details like how they use their phones.
The angle they usually hold their phones as well as how they use the screen to scroll and swipe is often predictable enough to create individual profiles of users’ behavior. And in this data-driven age, it’s no surprise that companies are doing just that by compiling dozens of signals related to consumers’ phone habits in order to create so-called behavioral biometrics that prevent fraud.
