On the Personalization of Image Content in Graphical Passwords based on Users' Sociocultural Experiences: New Challenges and Opportunities

Abstract

Recent works underpin the added value of considering users' past sociocultural experiences as a personalization factor for the image content used within graphical password schemes, since it has a positive impact on the security and memorability of the user-chosen passwords. This paper discusses the need for personalization of the image content used in graphical password schemes, as well as the initial steps towards the realization of an image content personalization framework that aims to achieve a better equilibrium between security and memorability. The paper also discusses emerging challenges related to the elicitation and maintenance of individual sociocultural-centered user models, the image content personalization mechanism and privacy considerations.
