The Effects of Culture on Authentication Cognitive Dimensions

Abstract

The purpose of this research is to answer the question: does selecting images from one’s culture improve the memorability of Recognition-Based Graphical Password (RBG-P)? The results show that the failure rate of authentication increases through the progression of consecutive three phases. The findings also suggest that cultural groups with higher number of images selected from own culture, inclined to experience lower failure rates and vice versa. In fact, the ISGs that selected from their own culture showed approximately half the means of failure of the groups that selected from other cultures. Resultantly, culture has significant effects on the password memorization, therefore, the designer must be motivated to provide cross-cultural interfaces that reduce the risk and improve usability of RBG-P which minimize the frustration associated with login failures. The quick depreciation of the success rate with the progress of the phases suggests the possibility of memory decay due to temporal effects.
