This work proposes a disaggregated whitebox-based nudge that visualizes critical information by segmenting users by decision-making and information processing styles. The study builds dynamic radar charts and parallel coordinates and evaluates short-term effects and perception through a think-aloud pretest and a representative online study (N=1,012).

While existing approaches are mainly blackbox based, showing aggregated visualisations as onesize-fits-all nudges, personalisation turned out promising to enhance the efficacy of nudges within the high variance of users and contexts. This article presents a disaggregated whitebox-based visualisation of critical information as a novel nudge. By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is moreeffective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users’ perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012) . Our findings suggest that dynamic radar charts present a moderately effective nudge towards  \nstronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.  \nARTICLE HISTORY  \nReceived 7 April 2020 Accepted 5 January 2021  \nKEYWORDS  \nNudging; whitebox; usable security; personalisation; passwords  \n1. Introduction  \nWhen forcing people ’s decisions towards a desired outcome without being convenient, people tend to find workarounds. For example, if users are forced to adopt higher online security, it may reduce their willingness to follow the advice when the benefits are not clear and the desired behaviour appears to be a disproportionately big effort (Merkel and Wiczorek 2012; Jeske, Coventry, and Briggs 2014a) . In that case, users often choose convenience over security. Instead of forcing, nudging is a promising concept to steer people‘s behaviour. A nudge is ‘any aspect of the choice architecture that alters people ‘s behaviour in a predictable way without forbidding any options or significantly changing their economic incentives ’ (Thaler and Sunstein 2009, p. 6) . However, Renaud and Zimmerman (2017) include nudges as well that come with a maximisation of nonmonetary utility, introducing the term of ‘enriched nudges’. Nudges can be applied in different ways. For instance, the advertisement industry uses nudges to convince people of buying a specific product. More favourably, applications in healthcare try to nudge people towards a healthier life. As it is a very subjective perception of what is best for people, ethical guidelines have to be considered. Renaud and Zimmermann (2018a) have derived general principles for et","cbCaisSv8bcK6Zf6","https://ap.wps.com/l/cbCaisSv8bcK6Zf6","pdf",2520930,25,"English","# Introduction\n# Background and Related Work\n# Disaggregated Whitebox Nudge Design\n# Visualisation Methods\n# Evaluation Method and Results\n# Findings and Discussion","[{\"question\":\"How does this research improve password nudges compared with black-box approaches?\",\"answer\":\"It replaces aggregated, one-size-fits-all visualizations with a disaggregated whitebox-based nudge that tailors critical information to user segments defined by decision-making and information processing styles.\"},{\"question\":\"What visualization techniques are used in the proposed nudge?\",\"answer\":\"The study designs a dynamic radar chart and parallel coordinates as disaggregated visualizations for critical password-security information.\"},{\"question\":\"How was the nudge evaluated and what were the main results?\",\"answer\":\"Effectiveness and user perception were assessed via a think-aloud pre-study and a representative online evaluation with 1,012 participants.
