Understanding Smartphone Sensor and App Data for Enhancing the Security of Secret Questions
|Name||Understanding Smartphone Sensor and App Data for Enhancing the Security of Secret Questions|
mostly all website use the forgot password methodology to retrieve the user password. some option like hint question is also for that. but it is not secure attacker can easily guess the password and take the personal data. for that we We develop a prototype on Android smartphones, and evaluate the security of the secret questions by asking the acquaintance/stranger who participate in our user study to guess the answers with and without the help of online tools; meanwhile, we observe the questions’ reliability by asking participants to answer their own questions. Our experimental results reveal that the secret questions related to motion sensors, calendar, app installment, and part of legacy app usage history (e.g., phone calls) have the best memorability for users as well as the highest robustness to attacks.
