Sir,
Please send me ppt on data storage on fingernail ,
I interested on this topic, i not getting this topic ppt anywhere,
So please send me as soon as possible.

I am Nagaraj, i am persuading 8th sem ECE in RYMEC bellary,pin code -583104.i am requesting to send me ppt for data storage on fingernail.and also with pdf meterial.

data storage on fingernail ppt

INTRODUCTION

Recently, there have been rapid developments in the field of information technology, resulting in the need to generate, store, and transport a large amount of information while ensuring data security, an important issue in today's digital age. To meet future demands in information technology, femtosecond laser pulse processing offers a powerful tool for developing new high-capacity devices because it allows fabrication of three-dimensional (3-D) structures inside a wide range of transparent materials. In particular, multi layered 3-D optical bit recording is a promising technique for nextgeneration computing systems because it offers a large recording capacity by stacking many recording layers without increasing the recording density per layer . Our goal is to realize optical data storage in a human fingernail for highly secure data transportation that does not suffer from problems such as theft, forgery, or loss of recording media . Japanese researchers are using femtosecond laser pulses to write data into human fingernails .Secure optical data storage could soon literally be at your fingertips thanks to work being carried out in Japan. Yoshio Hayasaki and his colleagues have discovered that data can be written into a human fingernail by irradiating it with femto second laser pulses. Capacities are said to be up to 5 mega bits and the stored data lasts for 6 months - the length of time it takes a fingernail to be completely replaced. (Optics Express 13 4560) Fingernail storage "I don't like carrying around a large number of cards, money and papers," Hayasaki from Tokushima University told Optics.org. "I think that a key application will be personal authentication. Data stored in a fingernail can be used with biometrics, such as fingerprint authentication and intravenous authentication of the finger." Fingernail storage is a method of writing data onto a human fingernail using a pulsed laser. The fluorescence of the nail, when exposed to ultraviolet (UV) light, is increased at points where data is written. Data can be read from the fingernail using a microscope while irradiating the nail with UV energy.
