Proposal for Approaches to Updating Software on Android Smartphone

It is important to provide personalized interventions that focus on the different security awareness of each user. We focus on updating operating system (OS) and seven major types of applications (Communication, Finance, Lifestyle, Games, Utility, Health, Entertainment) for smartphone users and aim to provide approaches that lead to updating of OS and seven types of applications (hereinafter, this is called “software”). We consider that user awareness of updating software may differ, and this relates to user understanding of the updating procedure. In this paper, we propose intervention methods according to users’ knowledge about update procedures. We conduct an online survey to evaluate effective approaches such as dialog message and type of incentive that increases the intention of smartphone users to update. We found that effective phrases of dialog messages differ according to the users’ understanding of the update procedures and that reward points are the best incentive for many users.
