Security Strength Indicator in Fallback Authentication: Nudging Users for Better Answers in Secret Questions
This addresses security vulnerabilities for users in authentication systems, but it appears incremental as it builds on existing fallback methods.
The paper tackles the problem of weak answers to security questions in fallback authentication by proposing a user interface design with visual feedback to nudge users towards stronger answers, though no concrete results or numbers are provided.
In this paper, we describe ongoing work that focuses on improving the strength of the answers to security questions. The ultimate goal of the proposed research is to evaluate the possibility of nudging users towards strong answers for ubiquitous security questions. In this research we are proposing a user interface design for fallback authentication to encourage users to design stronger answers. The proposed design involves visual feedback to the user based on mnemonics which attempts to give visual feedback to the user on the strength of the answer provided and guide the user to creatively design a stronger answer.
