The paper focuses on developing an advanced authentication mechanism to counteract the growing threat of keylogging attacks. Keylogging, a type of cyber-attack that captures keystrokes to steal sensitive information, poses a significant risk to traditional authentication methods that rely on keyboard input.

This paper introduces a novel security approach combining two key innovations: a dual-keypad input system and a visual authentication protocol. The dual-keypad system consists of two separate input keypad (Normal Keypad and Virtual Keypad), each responsible for a different aspect of the authentication process. This separation complicates the ability for key loggers to capture complete authentication sequences, thereby enhancing security.

Simultaneously, the visual authentication component introduces a dynamic, graphical verification process that complements the dual-keypad system. Users interact with visual elements—such as images or patterns—displayed on a screen, which are not susceptible to keylogging. This adds an additional layer of authentication that is both user-friendly and resistant to data capture by malicious software.

The integration of these two systems creates a multi-layered defence strategy. The dual-keypad mechanism reduces the risk of compromised keystrokes, while the visual authentication process ensures that even if keystrokes are captured, the authentication remains secure. The paper aims to deliver a robust, secure, and intuitive authentication solution that enhances protection against keylogging and other cyber threats, providing a reliable means of securing sensitive information in various applications.
