1. 21. Usable privacy for digital transactions : Exploring the usability aspects of three privacy enhancing mechanisms

   Författare :Julio Angulo; John Sören Pettersson; Simone Fischer-Hübner; Erik Wästlund; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Privacy-Enhancing Technologies; usability; usable privacy; mental models; mobile devices; security; digital transactions; e-commerce; User Interfaces; Information Systems; Informatik;

   Sammanfattning : The amount of personal identifiable information that people distribute over different online services has grown rapidly and considerably over the last decades. This has led to increased probabilities for identity theft, profiling and linkability attacks, which can in turn not only result in a threat to people’s personal dignity, finances, and many other aspects of their lives, but also to societies in general.
