A Next Generation Hybrid Scheme Mobile Graphical Authenticator

Abstract

Objectives: To provide a swift and simple mobile authentication method which are highly secured, easily remembered and prevents shoulder surfing attacks to improve existing mobile authentication methods. Methods: This paper is written using a problem-oriented research in improving the existing mobile authenticator which are vulnerable to shoulder surfing attack. Several qualitative researches are done by analyzing other related work done in the graphical authenticator field which are solving the same problem. A quantitative experiment method is used to test the proposed solution. Findings: Currently, most mobile devices are protected by a six pins numerical passcode authentication layer which is extremely vulnerable to Shoulder Surfing attacks and Spyware attacks. This paper proposes a multi-elemental graphical password authentication model for mobile devices that are resistant to shoulder surfing attacks and spyware attacks. The proposed Coin Passcode model simplifies the complex user interface issues that previous graphical password models have, which work as a swift passcode security mechanism for mobile devices. The Coin Passcode model also has a high memorability rate compared to the existing numerical and alphanumerical passwords, as psychology studies suggest that humans are better at remembering graphics than words. Novelty: Implementing multiple hidden elements in one button passcode which shuffles randomly to prevent shoulder surfing attack in mobile authenticator.
