BlindLogin: A Graphical Authentication System with Support for Blind and Visually Impaired Users on Smartphones

摘要

Most graphical password systems on smart phones do not consider the needs of blind and visually impaired users. The main objective of this paper is to propose a new graphical authentication system which combines the usability of the graphical password with the security of the textual password and allows all types of users, including the blind and visually impaired users to use the same authentication system on a smartphone without any extra costs for special hardware. 84.6% of those surveyed would recommend BlindLogin to their friends. 46.2% of the respondents also found the BlindLogin password to be easier to remember than the regular textual password. BlindLogin is a viable alternative as a universal graphical password authentication system.
