The main problem during the data transfer is security. In early days various data
transferring techniques has been used like wired data transfer, wireless data transfer,
satellite based data transfer and etc. But each techniques having various drawbacks like
security, data transfer rate, data loss and etc. As mentioned above, the most important
problem is the security and data breaching. Also various researches have been still going
on for secured data transfer. In case of high secured data transfer there are various
limitations like, one to one communication or need one authorized person to validate the
secured data. This makes more time consuming too. So these technologies are still in
research. In order to overcome these problems, in this project Light Fidelity (Li-Fi) has
been introduced. It is a new technique to transfer secured data using lights. For light via
data transfer LED (Light emitting diode) has been used in both transmitting and receiving
end. From one PC to another PC data can be transferred through light. In early research
the light will blink and flash during the time of data transfer that may irritate to the user
during the data transfer. Also the upload speed is not getting match with the download
speed, so that low data transfer rate will occur. There problems are overcome in this system
like, light will not flash during the time of data transmission, continuous light emission
will be transfer the data. Also upload speed is equal to the download speed, through this
method data transfer rate will be more high.
