User authentication and identification have always represented a challenge in web-based e-mail systems. The text-based authentication and user identification are not sufficient to address the security issues facing web-based e-mail systems. This sort of security is completely retrograde and obsolete for current security threats that easily undermine authentication, identification and non-repudiation. In this paper, a security increase in e-mail client is proposed by introducing multiple level authentication and identification in e-mail clients. The proposed multilevel authentication and identification consist of four levels, where level-1 is the text-based authentication, level- 2 involves an image based authentication and finally level-3 and level-4 use a specific algorithm that exploits the powerful properties of two mathematical operators called Pentors and UltraPentors applied against the image in level-2.
