DATA STORAGE ON FINGERNAILS
ABSTRACT:
In the rapid development in fields of information technology
securing the data is an crucial subject in todays digital age.So to
meet such demands the 3-Dimensinal data storage is used which
offers a high capacity and powerful processing tool that allows
fabrication of 3Dimensinal structure inside a wide range of
transparent material. 3D optical data storage is the term given to
any form of optical data storage in which information can be
recorded and/or read with three-dimensional resolution ...The
main aim of storing data on human fingernails is the secured
transportation of data without the issues of theft, imitation or any
sort of data loss. The data is written onto a fingernail by
exposing it to the femtosecond laser pulse which causes
structural changes in the fingernail and the increased
fluorescence effect is useful for reading out 3-Dimentional
recorded data. In order to write data on the nail,a laser pulse of
wavelength 800 nanometers is used.The diameter of a data bit is
about 0.003 mm and the spacing between the bits is 0.005 mm in
three layers at depths of 0.004,0.006, and 0.08 mm within the
nail.
