Behavioural biometric authentication with reference to keystroke dynamics

Abstract

Computer security has become an indispensable and critical aspect in the motif evolution and application of computer Since cyber crime and security remain the dominant preoccupations of the computer professionals in the global scenario the current study is attempted to set apart a secure security system to prevent or incapacitate all forms of attacks The major technical segments of computer security are more habitually identified in terms of confidentiality integrity and authentication or availability Of these authentication is our domain of research which is defined as confirming the truth of an attribute of a datum or entity The universal riddle of authentication and authorization in a computer system is access control newlineThe biometric authentication initiated on the exclusive physiological and behavioural aspects to identify a human being is reliable and easily verifiable and the second component of the study encompasses the expression and function of a generic biometric system Keystroke dynamics is singled out as a strong behavioural biometric authentication system which uses the manner and rhythm in which an individual types characters on a keyboard This procedure is explained with features like dwell time flight time di graph tri graph virtual key force and GA based wrapper approach This third division ends with the note that this scheme is efficiently helpful and successfully operational Since Particle Swarm Optimization is an inherent aspect in the revelation of Keystroke dynamics the fourth section is devoted to the basics of PSO newline newline
