Shoulder Surfing attack in graphical password authentication
Information and computer security is supported largely by passwords which are the principle part of the authentication process. The most common computer authentication method is to use alphanumerical username and password which has significant drawbacks. To overcome the vulnerabilities of traditional methods, visual or graphical password schemes have been developed as possible alternative solut...
متن کاملA Shoulder-Surfing Resistant Graphical Password Scheme - WIW
We propose a new graphical password scheme. It is de ned as a challenge-response identi cation. Hence, a password in our scheme is time-variant. User who knows the password is able to meet the challenge and to respond correctly. As a consequence, our graphical password scheme is shoulder-sur ng resistant. An attacker still cannot tell what the password is, even if he/she has lmed a user's login...
متن کاملNovel Shoulder-Surfing Resistant Haptic-based Graphical Password
Graphical password schemes are believed to be more secure and more resilient to dictionary attacks than textual passwords, but more vulnerable to shoulder surfing attacks. In this work, we design a new graphical password which is larger in the possible passwords’ space than in similar schemes and it is more resilient to shouldersurfing attacks. Personal entropies are integrated into the system ...
متن کاملReview on Color Password to Resist Shoulder Surfing Attack
Since conventional password schemes are vulnerable to shoulder surfing, many shoulder surfing resistant graphical password schemes have been proposed. However, as most users are more familiar with textual passwords than pure graphical passwords, text-based graphical password schemes have been proposed. Unfortunately, both the text-based password schemes and graphical password schemes are not se...
متن کاملUser’s Affinity of Choice: Features of Mobile Device Graphical Password Scheme’s Anti-Shoulder Surfing Mechanism

Unfortunately, the features best suited for anti-shoulder surfing mechanism on mobile devices are still an uncertainty. Furthermore, it is futile to try embedding every single available feature into a single graphical password anti-shoulder surfing mechanism for mobile devices. I...
