Graphical authentication is being widely accepted as a collaborative and an alternative to textual password authentication systems because it has reasonably solved the problem of memorability. However, the present graphical authentication system does not provide efficient security for the systems. In this paper, a Secret-Sketch graphical authentication system (SEC-SKETCH) is proposed to enhance the security of computer and network-based systems. It encompasses three states for its completion commencing from registration to login and authentication phases. Criteria such as Threshold and Percentage Accuracy which provide strong resistance to hidden-camera and shoulder attacks are complemented in the mode of analysis. To assess how effective and user-friendly the suggested system is, a demo system that utilizes traditional recall techniques like Passdoddle, Quantitative Draw-A-Secret (QDAS), Syukri, and Draw-A-Secret (DAS) is developed and then compared with the SEC-SKETCH scheme. The experiment showed that SEC-SKETCH performed the best with 0.10% FNMR, 0.15% FMR, and 0.02% EER compared to all other recall-based technique.
