Abstract
Information communication between networks is greatly growing, and its security becomes more important. In this article, a new way of network security communication, namely bar code communication was investigated. It used the general principle of the computer to quantify the information and generate the barcode instantly, and it was showed by using the micro-display. Then the micro-camera is used to identify the barcode on the display to restore the original information in the optical principle. Faster and more efficient communication technologies, such as the principle of macro wireless communication technology, can receive complete information to achieve the purpose of information transmission. The bar code information communication method was one-way and irreversible, and it was safe and can ensure communication security between networks. It is the fourth communication method different from wired, wireless and medium modes: one-way bar code communication mode (referred to as “one-way communication”).
Highlights
Speaking, barcode communication has existed since John Kermode, the odd "whimsical" American inventor, created the first barcode in the Westinghouse laboratory, which was only used in mail sorting at that moment
This paper proposes, in view of the high security requirements for network-based communication, the use of One-way Barcode Communication (OBC) to transmit between networks relatively fixed messages
When government departments, social groups and economic organizations have to publish any information of fixed content in a timely way, fixed standard and fixed format, and wired networks, wireless networks and media copies may not be safe enough for such purposes: this kind of communication will ensure safe transmission
Summary
Barcode communication has existed since John Kermode, the odd "whimsical" American inventor, created the first barcode in the Westinghouse laboratory, which was only used in mail sorting at that moment This invention, was later improved and widely employed in people's daily life and work, and has spread from complex single use at the beginning, to today's vast modern application. OBC refers to a special way of communication to transmit messages between networks by employing basic principles of computer application, optical principles of barcode technology (e.g., RFID technology) [1,2,3], and micro-range wireless communication (e.g., NFC technology) [4,5,6,7] This method is safe, reliable and practical, and addresses the concerns of government departments, social groups, and economic organizations about communication security.
