BIOMETRIC RECOGNITION OF HUMANS USING SCANNED IMAGES OF THE RETINAL PART OF THE EYE

Abstract

Biometrics finds a lot of application in the modern day security aspects whether it may
be in industrial sector, defense sector or in domestic sectors. In this world, without
biometrics, it is very very difficult to incorporate the security measures in any organization.
Hence, personal identification can be very important problem in any bio-metric recognition
scenarios. Entry of a person into an organization in the work environment plays a very
important role as unauthorized persons if entered into a premises may create a flutter &
inviable to some terrorist attacks. Hence, biometrics of an authorized person into the work
environment plays a very im-portant role. Quite a no. of bio-metric methods exists for
identification purposes, viz., physiological & behavioural. Some of them are hand, iris,
voice, finger-print, human face, ear, gait/gesture, posture, thumb, ear, vien, code,
password, signature, pattern, palm print, etc.. As quite a substantial no. of biometric
methods for detecting the human beings exists by automatic means, retina scan is being
considered as the biometric identity in the research work undertaken by us because of a
large number of advantages over the other biometric identities. For biometric recognition
of a person using retina scans, a number of methods exists in the literature. In this context,
fractal dimension method is one of the method that could be used. Hence, the retinal
recognition is performed in our proposed work for identifying the person by developing
new approaches using Fractal Dimension methodologies. In this paper, 100s of papers are
being surveyed upon the chosen research topic and a brief survey of the existing
methodologies that are used for the biometric recognition of personnels using the human
being’s retina is being presented. In fact, this paper is a collection of the works done by
various authors in the relevant field till date. This survey paper aims at providing a basic
information about the on-going current works & the completed works in the field of
biometric recognition using the retina so that the paper give a base for the oth-er
researchers to start the their work.
