An Association-Based Graphical Password Design Resistant to Shoulder-Surfing Attack

Abstract

Data and computer protection is endured largely by countersigns which are the principle part of the authorization and authentication cognitive process. The most common information processing system authentication process is to apply alphanumerical username and password which has important drawbacks. Graphical passwords are often deliberated prone to shoulder-surfing attacks, where attackers can sneak a user's password by peeking over his or her shoulder in the certification process. Graphical passwords seem to be the solution as it is described more in the design structure of the authentication. A graphical password is an authentication scheme that works by accepting the user select from images, in a particular grade, demonstrated in a graphical user interface (GUI). The proposed research is an approach to enhance the subsisting Graphical Password techniques and resist against attacks like Shoulder Surfing. Based on the principle of zero-knowledge cogent evidence protocol, the additional improvement is the primary figure to overcome the shoulder-surfing attack issue without adding any additional complexity into the authentication process.
