Encouraging users to improve password security and memorability

M. Yıldırım, I. Mackie
2019 International Journal of Information Security  
The study also suggests that our password creation methods are much more efficient than strict password policy rules.  ...  A study has been conducted to evaluate the efficiency of the proposed password guidelines.  ...  has been extensively studied in the past, there are no empirical studies that test the effectiveness of password creation methods.  ...

Just What Word Did Mandel'shtam Forget? A Mnemopoetic Solution to the Problem of Saussure's Anagrams

M. Gronas
2009 Poetics Today  
Both the retrieval of a word on the tip of one's tongue and the (re)construction of an anagram involve sorting through the phonetic and semantic cues that hint at the absent target word.  ...  The case study is provided by Osip Mandel'shtam's poem "I have forgotten the word that I wanted to  ...  As the term itself implies, this is a field that borders on both poetics and cognitive science (or, more precisely, on the cognitive study of memory): it focuses on the mnemonic aspects of the creation  ...

User-generated free-form gestures for authentication

Michael Sherman, Gradeigh Clark, Yulong Yang, Shridatt Sugrim, Arttu Modig, Janne Lindqvist, Antti Oulasvirta, Teemu Roos
2014 Proceedings of the 12th annual international conference on Mobile systems, applications, and services - MobiSys '14  
This paper studies the security and memorability of freeform multitouch gestures for mobile authentication.  ...  For example, entropy-based metrics used for text-based passwords are not suitable for capturing the security and memorability of free-form gestures.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.  ...

Towards Human Computable Passwords

Jeremiah Blocki, Manuel Blum, Anupam Datta, Santosh Vempala, Marc Herbstritt
2017 Innovations in Theoretical Computer Science  
As an application, we propose a family of human computable password functions f k1,k2 in which the user needs to perform 2k 1 + 2k 2 + 1 primitive operations (e.g., adding two digits or remembering a secret  ...  Thus, our human computable password schemes can maintain strong security guarantees even after an adversary has observed the user login to many different accounts.  ...  Figure 5 Table of Mnemonic Helpers to Help Learn Any Secret Mapping Creating an Account To help the user create an account the computer would first pick a sequence of single-digit challenges C 1 , .  ...

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  
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.  ...  They promise natural and efficient interaction, but suffer from a lack of affordances and thus require learning on the part of the user.  ...  EXPERIMENT 1: INFLUENCE OF INSTRUCTION The first experiment was aimed at understanding the influence of an instruction on participants' gesture password creation.  ...

From the Quest to Replace Passwords towards Supporting Secure and Usable Password Creation

Verena Zimmermann
These include the creation of weak passwords or the reuse of passwords across accounts.  ...  Because the security of password authentication largely depends on the password creation and handling of the user, further research was needed to explore measures that support secure and usable password  ...  Empirical research found that the strength of random passwords and mnemonics were similar and that both were stronger than user-generated passwords [340] .  ...
