A Study of the consideration of bio monitoring of trace Elements in the human nail for the Biometric Authentication

Abstract

the studies of trace element composition in the human nail is called ashuman bio monitoring. The composition of the chemicals and traceelements and concentration of the chemicals and trace elements in thehuman body fluids and human body tissues are observed .Theconcentration of trace elements for a healthy human being is stable for aparticular period of time in their nail and also the composition of chemicalelements in the nail differs to each individual. So the humans nails can beused as the bio marker for monitoring or quantifying the composition ofchemicals (major and trace elements) in the human body. So traceelement's composition and concentrations in the nail can be considered forBio-metrics authentication in future. Because the chemical composition ofnail and chemical concentration in the human nail differ from one peopleto another people and so this can be used to identify the individual infuture.Index terms–elements, trace elements, human bio monitoring, humanbody, nail
