Abstract

Mobile devices, which would hold a lot of private and sensitive information, are now a requirement in people's daily lives due to their rising capability. This makes smartphones a top target for cyberattacks, as either the loss of such mobile devices or unauthorised access will result in a breach of personal data and financial harm. Over the past few years, a number of new types of authentication systems have been presented in an effort to allay that worry. One of those classes is Graphical Authentication (GA), which is the subject of this study. Due to their primarily graphics-oriented nature, superior memorability versus text-based schemes, and lack of additional hardware requirements, GA schemes are more well-liked and preferred for smart devices. The majority of these GA systems are vulnerable to many well-known attacks, including brute force, shoulder surfing, and smudging. As a result, a novel hybrid authentication scheme, Passpoints and Press Touch Code, or PTC, that smoothly combines two distinct yet widely used authentication techniques is proposed in this work. By thwarting those well-known threats, this new technique aims to provide a higher level of security.
