DESCRIPTION:Commitment devices are a technique from behavioral economics t
 hat have been shown to mitigate the effects of present bias—the tendency
  to discount future risks and gains in favor of immediate gratifications. 
 In this paper\, we explore the feasibility of using commitment devices to 
 nudge users towards complying with varying online security mitigations. Us
 ing two online experiments\, with over 1\,000 participants total\, we offe
 red participants the option to be reminded or to schedule security tasks i
 n the future. We find that both reminders and commitment nudges can increa
 se users' intentions to install security updates and enable two-factor aut
 hentication\, but not to configure automatic backups. Using qualitative da
 ta\, we gain insights into the reasons for postponement and how to improve
  future nudges. We posit that current nudges may not live up to their full
  potential\, as the timing options offered to users may be too rigid.\n\n\
 nBio:\nDr. Alisa Frik is a postdoctoral researcher at the International Co
 mputer Science Institute (ICSI) and the University of California\, Berkele
 y. She works with the Usable Security and Privacy research group\, under t
 he direction of Dr. Serge Egelman. Her current projects are about usable s
 ecurity for emerging healthcare technologies for older adults\, increasing
  users’ computer security compliance by reducing present bias\, personal
 ised security nudges\, bystanders' privacy\, privacy concerns of domestic 
 workers\, privacy expectations regarding always listening voice assistant 
 devices\, and the effects of ad-blockers on consumers’ welfare. She has 
 obtained a Ph.D. degree in Behavioral and Experimental Economics and Socia
 l Sciences from the University of Trento\, Italy. She also spent 1 year vi
 siting the Carnegie Mellon University\, where she worked with Prof. Alessa
 ndro Acquisti. She has done research on the the impact of risk tolerance a
 nd need for control on the privacy related behaviors\, and implicit measur
 ement of privacy risk attitudes\; factors affecting consumers' trust with 
 respect to how e-commerce websites will treat their personal information a
 nd subsequent intention to purchase from such websites. Dr. Frik’s prefe
 rred methodological tools include lab and field experiments\, surveys\, fo
 cus groups\, interviews\, and participatory design.\n
