Data Storage On Fingernail PPT

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.

Recent experiments with fingernail storage, conducted by Yoshio Hayasaki of Tokushima University (Japan), have involved small regions of a single nail, measuring approximately two millimeters (mm) square. A pulsed laser is used, at a wavelength of 800 nanometers (nm), to write the data onto the nail. Each data bit measures approximately 0.003 millimeters (mm) in diameter. Individual data bits are spaced 0.005 mm apart, in three layers at depths of 0.04, 0.06, and 0.08 mm within the nail.

Fingernail storage has a limited life because human nails grow out. The average human fingernail is completely replaced by the body every six months, assuming the nail is clipped short at regular intervals. Fingernail storage has been suggested as a biometric means of identification, and also for storing critical medical information for use in emergencies.

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, multilayered 3-D optical bit recording is a promising technique for next-generation 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 .


BASIC APPROCH

The team's approach is simple: use a femtosecond laser system to write the data into the nail and a fluorescence microscope to read it out. The key to reading the data out is that the nail's fluorescence increases at the point irradiated by the femtosecond pulses. Initial experiments were carried out on a small piece of human fingernail measuring 2 x 2 x 0.4 mm3. The writing system comprises a Ti:Sapphire oscillator and Ti:Sapphire amplifier. Pulses of less than 100 fs at 800 nm are then passed through a microscope and focused to three set depths (40, 60 and 80 microns) using an objective lens. Each "bit" of information has a diameter of 3.1 microns and is written by a single femtosecond pulse. A motorised stage moves the nail to create a bit spacing of 5 microns across the nail and a depth of 20 microns between recording layers.


DATA IS LITERALY ON FINGER NAIL

As technology and science develop, new, more advanced means of storing data are discovered. However, up until know, nobody thought of using the human body as a storage media .

According to Jacqueline Hewett for physicsweb.org, Yoshio Hayasaki of Tokushima University and colleagues have discovered that data can be written into a human fingernail by irradiating it with femtosecond laser pulses. Capacities are said to be up to 5 mega bits and the stored data lasts or 6 months, which is the length of time it takes a fingernail to be completely replaced.

"I don't like carrying around a large number of cards, money and papers," says Hayasaki. "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.


DNA STORAGE VS FINGERNAIL STORAGE

Storing messages in DNA it might be interesting to explore ways to encode large volumes of data directly into parts of the human body. Storing data in DNA has the advantage that data is distributed throughout the entire body. Furthermore, if stored in the sex-cells, stored data can be passed down to offspring. A disadvantage of using DNA for data-storage is the possible unanticipated effects on cell development and health. Messing with DNA is risky -- it may be safer to store data in other parts of the human body (with the one potential disadvantage that such data would not be passed down via heredity).Storing data on fingernails is a safe process. Using this technology we save our data without having its bad effect on body.thus it is a safer process as compared to DNA STORAGE. Here are some suggestions for parts of the human body that might be good media for data-storage:


OTHER PARTS OF HUMAN BODY IN WHICH DATA CAN BE STORED

The lens of the eye.
The lens of the human eye may provide a good medium for encoding data. Data would be written into it using laser holographic etching. An advantage of this approach is that biometric authentication of user-access to data could be integrated with the data itself. For example, to access the data that is encoded onto the lens of your eye, you would look into a reader that would first do an iris scan to authenticate your identity and permission to read the data, and would then read/write the data as you request. A disadvantage of using the lens to store data is that it might not be reusable -- it may be difficult to erase or overwrite data on the lens, although the jury is still out on this question. Another important consideration would be to ensure that the data encoding did not interfere with vision, although it is not expected that this would be a problem as it is easy to encode data microscopically such that it would not affect visual refraction.


HOW DATA IS STORED ON FINGERNAILS

There is an increase in fluorescence intensity compared with the surrounding auto-fluorescence intensity at a structural change produced by a focused femtosecond laser pulse inside a human fingernail. The spectrum of the increased fluorescence coincides with the auto-fluorescence spectrum of a fingernail and that of pure keratin. The increased fluorescence intensity is also observed in a heated fingernail. It is suggested that the increased fluorescence is a result of a local denaturation of keratin protein caused by the femtosecond laser pulse irradiation. The increased fluorescence effect is very useful for reading out the bit data recorded inside a human fingernail. We also demonstrate that three-dimensionally-arranged structural changes can be read out with little cross-talk by making use of the increased fluorescence. Furthermore, we demonstrate that fluorescence can be observed for up to 6 months, corresponding to the time required for a fingernail to grow from root to tip.
