Description : Communication may be considered as the art of expressing oneself coherently. In the present electronic era, communication has taken the definition: the technique or process of exchange of meaningful data among entities. With technology as the catalyst, communication has burgeoned over the last couple of decades. The notion of a physical medium for communication is fast vanishing. Technology has it that today communication is possible without actual physical connection between devices. This project explores one such technology namely, optical communication. Infrared rays are an efficient means of communication and data transfer. The merits of this technique are that it does not require physical connection between devices, it is cost effective and it is simple and easy to implement. This project involves setting an optical communication page link between two computers and transmitting and receiving data. Each computer has a transmitter and receiver attached to it and is thus capable of transmitting as well as receiving data. The data to be transferred is first collected. The compression algorithm is performed on the data. Then the encryption algorithm is used to encrypt the data to provide a basic level of security. Finally the data are converted to infrared rays and then transferred
Technology Used : Java ,Swing
Algorithms : RSA ,DES AND SHA algorithms
