Messages and Incentives to Promote Updating of Software on Smartphones

To improve the rate of taking security action, it is important to promote personalized approaches for each user. Related works indicate phrases and UIs of dialog messages and incentives that influence a user’s action. In our previous work, we focused on smartphone users updating software, and proposed appropriate phrases of dialog messages according to the user’s understanding of the updating procedure, as well as the type of software. We also analyzed appropriate incentives. However, in the terms of level of literacy, the effectiveness of the UI of dialog messages and the volume of incentives remain unclear. In this paper, we conducted a user survey to analyze appropriate UIs according to the user’s understanding of the updating procedure and the appropriate volume of incentives. As a result, we confirmed different UIs are effective according to the user’s understanding of the updating procedure. In addition, we found an appropriate volume of points, mobile data, and coupons in order to promote the updating of software.
