This document discusses graphical passwords as an alternative to traditional text-based passwords. It provides an overview of existing graphical password authentication techniques, which fall into two categories: recognition-based and memory-based approaches. The paper also proposes a new image-based graphical password system that segments a submitted image into pieces and authenticates the user based on their ability to reassemble the original image from scrambled pieces. The system aims to provide password security comparable to text-based passwords while addressing issues like shoulder surfing.
