Usability and security evaluation of GeoPass

Julie Thorpe, Brent MacRae, Amirali Salehi-Abari
2013 Proceedings of the Ninth Symposium on Usable Privacy and Security - SOUPS '13  
We design, implement, and evaluate GeoPass: an interface for digital map-based authentication where a user chooses a place as his or her password (i.e., a "location-password").  ...  The results of our user study found that 97% of users were able to remember their location-password over the span of 8-9 days and most without any failed login attempts.  ...  We thank the participants of our user study. We are grateful to Apu Kapadia, Stuart Schechter, and the anonymous reviewers for their insightful suggestions for improving this paper.  ...

A multi-word password proposal (gridWord) and exploring questions about science in security research and usable security evaluation

Kemal Bicakci, Paul C. van Oorschot
2011 Proceedings of the 2011 workshop on New security paradigms workshop - NSPW '11  
First, we introduce and give a technical description of gridWord, a novel knowledge-based authentication mechanism involving elements of both text and graphical passwords.  ...  While the core ideas behind gridWord are well-formed, and may be viewed as a new variation of old (text-based) ideas of building passwords from multiple words, many aspects including recommended parameterization  ...  The second author is Canada Research Chair in Authentication and Software Security, and acknowledges NSERC for funding the chair, a Discovery Grant, and a Discovery Accelerator Supplement.  ...

A second look at the usability of click-based graphical passwords

Sonia Chiasson, Robert Biddle, P. C. van Oorschot
2007 Proceedings of the 3rd symposium on Usable privacy and security - SOUPS '07  
We also present a first look at whether interference from having multiple graphical passwords affects usability and whether more memorable passwords are necessarily weaker from a security point of view  ...  Click-based graphical passwords have been proposed as a usable alternative to text passwords.  ...  ACKNOWLEDGMENTS We thank Julie Thorpe for her collaboration in this project, the participants of our lab study, and Prosenjit Bose, Louis D.  ...

Camera Based Two Factor Authentication Through Mobile and Wearable Devices

Mozhgan Azimpourkivi, Umut Topkara, Bogdan Carbunar
2017 Proceedings of the ACM on Interactive Mobile Wearable and Ubiquitous Technologies  
In a user study with 42 participants over 8 days in 3 sessions we found that Pixie outperforms text based passwords on memorability, speed, and user preference.  ...  A quick and familiar user action of snapping a photo is sufficient for Pixie to simultaneously perform a graphical password authentication and a physical token based authentication, yet it does not require  ...  USER STUDY We have used a lab study to evaluate the usability of Pixie's trinket based authentication and compared it against text-based passwords.  ...

Integrating Visual Mnemonics and Input Feedback With Passphrases to Improve the Usability and Security of Digital Authentication

Kevin Juang, Joel Greenstein
2018 Human Factors  
Based on a pilot study, we settled on ten rows of text as a tradeoff between security and usability.  ...  The correct input text is automatically mapped to a certain color and position, which are tied together for redundancy.  ...

What You See is Not What You Get

Yan Li, Yao Cheng, Yingjiu Li, Robert H. Deng
2017 Proceedings of the 2017 ACM on Asia Conference on Computer and Communications Security - ASIA CCS '17  
In this paper, we propose a series of leakage-resilient password entry schemes on stand-alone smart glasses, which are gTapper, gRotator, and gTalker.  ...  The results of our user study reveal that the proposed schemes are easy-to-use so that users enter their passwords within moderate time, at high accuracy, and in various situations.  ...  Finally, gTalker recognizes the number s ik spoken by the user and enters p k based the mapping between the original keypad and the transformed keypad in that round.  ...

Shoulder Surfing: From An Experimental Study to a Comparative Framework

Leon Bošnjak, Boštjan Brumen
2019 International Journal of Human-Computer Studies  
The results have important implications for future shoulder surfing studies and the field of Password Security as a whole.  ...  Despite a multitude of proposed solutions over the years, few have employed empirical evaluations and comparisons between different methods, and our understanding of the shoulder surfing phenomenon remains  ...  them (particularly between the different types of graphical passwords, such as recognition-based, pure and cued recall- based, and hybrid schemes).  ...

Isn't that Fantabulous

Andrew M. White, Katherine Shaw, Fabian Monrose, Elliott Moreton
2014 Proceedings of the 2014 workshop on New Security Paradigms Workshop - NSPW '14  
Over the past few decades, passwords as a means of user authentication have been consistently criticized by users and security analysts alike.  ...  Unfortunately, much of the formal research on user authentication has focused on attempting to provide alternatives (e.g., biometrics) to password-based mechanisms (or belated analyses of users' password  ...  Allowing users a significant period of time in which to become accustomed to the new system highlights the issue of 'password interference' [16] , where the necessity of maintaining multiple passwords  ...

Learning and performance with gesture guides

Fraser Anderson, Walter F. Bischof
2013 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems - CHI '13  
They promise natural and efficient interaction, but suffer from a lack of affordances and thus require learning on the part of the user.  ...  Next, we present two studies that help us better understand the role of visual feedback, finding that it has a dramatic effect on the degree to which gestures are learned.  ...  This approach was tested in pilot studies, but did not have the desired effect.  ...
