were reported to be too many and caused distraction. Participants expressed a degree of concern on sharing personal and academic information with little or no privacy concern on using favorite questions. Keywords—Online examination, profile, challenge questions, authentication, security, usability

be in the authentication pipeline of a vision-based system), and (3) some usage scenarios preclude either taking a sufficiently clear picture and/or the use of barcodes. We develop and evaluate a system we call Loud-and-Clear (L&C) authentication, which, like Seeing-is-Believing, places little demand on the human user

or entirely certify the user’s claim of identity is becoming progressively more attractive since it establishes one’s identity based on “who he is”. Among the various forms of biometrics for use as a form of security is voice biometrics – the use of a person’s voice to certify they are who they claim to be

of recognizing an individual based on his or her physical or behavioral traits, is beginning to gain acceptance as a legitimate method for determining an individual’s identity. Biometric systems have now been deployed in various commercial, civilian, and forensic applications as a means of establishing identity

, and evaluate Q-A, a novel cognitive-question-based password system that requires a user to enter the letter at a given position in her answer for each of six personal questions (e.g. “What is the name of your favorite childhood teacher?”). In this scheme, the user does not need to memorize new, artificial

are expected to have maximum similarity between their biometrics. Classifying identical twins is a challenging problem for some automatic biometric systems. In this paper, we summarize the exiting experimental results about identical twins ’ biometrics including face, iris, fingerprint and voice verification

applications, to be usable by a broader spectrum of the average population, and to function more reliably under realistic and challenging usage conditions. In this paper, we summarize the emerging architectural approaches for interpreting speech and pen-based gestural input in a robust manner--- including

Biometric system such as finger, face, iris, ear, voice, DNA etc. is used for personal identification. Authentication based on vein pattern is an approach that uses the vast network of blood vessels that lie underneath a skin on back of the hand. Vein pattern are unique and also difficult

In today’s context security is a main concern of most of the organization. Therefore for their own employee and customer they need a very reliable and robust security system which authenticates people based on a criteria which does not waste the time of people in due cause of authentication

with the help of his/her invigilator and a unique ID will be generated.At the examination center, he/she will enter the ID through voice commands with the help of invigilator. After entered the Id and password the exam will start by the invigilator then what ever the candidates doing in a system all
