Intrusion Prevention by Native Language Password Authentication Scheme

Abstract

AbstractIn a multi-user system, user name and password serves to authenticate the user. Generally users select alphanumerical passwords or textual passwords in English. It is easy for the intruder to crack these passwords by eaves dropping, password stealing, dictionary attack and shoulder surfing. To overcome these vulnerabilities, graphical password schemes have been introduced. An intruder can easily break the simple graphical password authentication schemes by shoulder surfing and hidden cameras. In this paper a new shape based textual authentication scheme for native language passwords is proposed. User selects a character from his native language and the shape of this character becomes password criteria. The proposed authentication scheme is resistant to attacks like password stealing, eves dropping, shoulder surfing and hidden cameras because every time user enters a new password.KeywordsShape based authenticationTextual PasswordNative language characterIntrusion prevention
