Abstract

This project is about secure data transfer using wireless infrared communication. Wireless communication, as the term implies, allows information to be exchanged between two devices without the use of wire or cable. Infrared is a mature and stable technology that has been around for many years and is on most portable devices whereas Bluetooth has not taken hold as yet and is not included in any of the above operating systems. IrDA infrared is secure as it is purposely limited at one meter line-of-sight and thirty degrees cone. Keeping in shorter distance, infrared uses very little power, which is an important factor to consider when it comes to handed devices. This project is deal match two ways to complete this project. The first one is in software using visual basic 6.0, this software is use to encrypt and decrypt the user data for security form hacker. By study this programming; we can produce the better source code. From this source code we used to encrypt the data and decrypt it back for other person who is define by user. In second step is using hardware by construct one IR transceiver circuit which it connect infrared component. The IR transceiver circuits are connecting to serial port at personal computer. For this circuit, we simulate it using workbench multisim, this simulation is important because it can help us to construct the better IR circuit. At the end of this project, we will be produce one type security data transfer device using wireless infrared communication. As the result, this project can be used to transfer a data from one personal computer to another computer by using wireless infrared communication. In addition, to the data transfer, this project also includes an encryption data transfer for a security purpose.
