Certain investigation on contactless Palmprint and identification Methodologies

Abstract

The use of biometric systems, which recognize individuals based ontheir physical characteristics rather than their knowledge (e.g., a password) orobjects (e.g., a smart card), is an expanding and increasing component ofdaily life for many people. An easy-to-capture biometric modality that couldwork well with a commodity camera is palmprint. In this context, biometricsystems based on palmprint are commonly well acknowledged by users,because they are not perceived as too intrusive or privacy-sensitive.Unfortunately, prior versions of palmprint recognition rely on touchbasedacquisitions with pegs that restrain the position of the hand, reducingtheir ease of use. The main drawbacks of touch based system are dirt,distortion and user acceptability. Distortion is caused by non-uniformpressure of the hand on the sensor. Dirt accumulates after repeatedacquisitions and can reduce the quality of acquisition. User acceptability canbe problematic if people dislike touching the surface that has been touched by newlineother users. newline newline
