Graphical Password Authentication, An Two- Step Authentication

Abstract

In response to the escalating challenges in digital security, this paper introduces a paradigm-shifting approach to password authentication. Departing from conventional methods, our innovative two-step authentication process seamlessly integrates color patterns and image placement, creating a dynamic and personalized user experience. The first step invites users to engage with a spectrum of vibrant colors arranged in intricate patterns. Leveraging the human brain's visual acuity, users must replicate the displayed color pattern, introducing an intuitive yet robust layer of authentication. This step not only enhances security by introducing a dynamic element but also affords users the opportunity to express their individuality through personalized color schemes. Transitioning seamlessly to the second step, users are presented with a grid of empty boxes awaiting carefully selected images. Unlike generic two-factor authentication, these images hold personal significance to the user, requiring them to drag and drop each image into its designated box. This fusion of personalization and security establishes an additional, personalized barrier against unauthorized access. The system's adaptive complexity ensures a tailored authentication experience, dynamically adjusting the intricacy of color patterns and image placement challenges based on user familiarity. By prioritizing user-centric design, our password authenticator aims to redefine the intersection of art and security, creating a visually captivating yet robust defense against unauthorized access.
