Analyze the application of digital communication in the library information security based on RFID

Abstract

With the rapid progress of science and technology, information and communication technology began to come into people's lives. As one of the branches of information and communication technology, radio frequency identification (RFID) technology gradually extended to all areas of life. This paper focuses on the application of RFID in libraries digital information security and expounds the advantages of radio frequency identification technology in library information security technology. Comparing it with the traditional bar code identification technology, RFID technology performs better in library information management. After installing the RFID system, it is easier for the library to store and integrate book information. At present, most library RFID systems use two operating frequencies: high frequency and ultra-high frequency. This paper analyzes the performance differences between HF RFID and UHF RFID in library scenarios. The purpose of the comparison is to hope that libraries can choose and install appropriate identification frequencies according to their own needs. At this stage, RFID technology is superior to barcode technology in many aspects, but if it can solve the problems of cost, safety, and anti-interference ability, more and more libraries will be willing to introduce this technology.
