As RFID technology has been developed rapidly, its technical potential has it be widely used in many industrial fields. Particularly, in the physical distribution industry, the introduction of RFID has enormously contributed to effectively monitoring locations and information of products in real-time. Also, a significant decline in tag prices and RFID related technical competitiveness enabled each tag to be managed much more minutely by attaching it to an item, not a pallet nor a container. However, if a very large volume of tag data are continuously flowed into a RFID middleware with limited hardware resources, its entire data processing time may become considerably longer. Therefore, specific technologies are in great demand to handle and further to reduce the load of the middleware. In this paper, we proposed a mobile agent-based software module to efficiently reduce the load of the middleware by pre-processing a lot of tag data while items are in transit. Simulation results show that using the proposed software module considerably enhances the speed of processing tag data than otherwise. This behavior increases the tag recognition rate in a certain time limit and improves reliability of RFID middlewares.

Various kinds of studies for building up U-Korea are now underway. Especially, RFID comes into the spotlight as a core technology of Ubiquitous. Though, the development of higher levels of application is far behind the hardware-based technology in RFID application system. For that reason, In this paper suggests technology using RFID on Ubiquitous and embodies the effective health care application which is one of the application services of user-centered environment It realizes the system which enables us to manage and send data about changing prescriptions and locations of patients effectively under the basis of RFID tag and mobile devices. It also provides the high quality of practical effectiveness of entire system throughout the realization of applications of application server and mobile device. on the basis of framework for providing the various kinds of services and physical elements.

A RFID system is a technology for detecting information on an object through wireless communication between a tag on the object and a reader, and its applications are being expanded to various areas. Because of its wireless communication, however, there are many vulnerabilities in security. Until now, many studies have been executed in order to solve problems related to the security and stability of RFID. In order to resolve vulnerabilities in existing security methods for privacy protection, this study proposed an authentication protocol that uses hash values received from tags and random numbers. When the proposed protocol was implemented, it was safe from various types of attacks between tag and reader and between reader and DB. Furthermore, compared to recently proposed protocols, it could implement a RFID system with enhanced security and less computation in tags.

RFID system is used in several fields such as traffic and access control. The study about RFID security is actively progressed as security threat has been increased. This paper suggests matrix-based authentication protocol. And we analyze the safety of authentication protocol and compares the effectiveness of the protocol with other authentication protocols. The suggested authentication protocol secures from wiretapping attack, replay attack, and spoofing attack, and reduces overload of back-end database so that has efficient performance.

RFID(Radio Frequency Identification) is use of an RFID tag applied to object for the purpose of identification and tracking using radio waves. Recently, it is being actively researched and introduced in logistics and manufacturing. RFID portals in supply chains are meant to identify all the tags within a given interrogation zone. Hence the hardware and software mechanisms for RFID tag identification mostly focus on successful read of multiple tags simultaneously. Such mechanisms, however, are inefficient for determining moving direction of tags, sequence of consecutive tags, and validity of the tag reads from the viewpoint of workflow. These types of problems usually cause many difficulties in RFID portal implementation in manufacturing environment, there by having RFID-system developers waste a considerable amount of time. In this research, we designated an RFID portal system with SDO(Sequence, Direction, and Object-flow)-perception capability by using fundamental data supplied by ordinary RFID readers. Using our work, RFID system developers can save a great amount of time building RFID data-capturing applications in manufacturing environment.

Recently, the RFID technology is combined with a u-healthcare services is an emerging trend in the field of medical services. u-healthcare service, as covering the field of personal health information beyond the level of simple health screening and treatment of life are closely related. Considering security, invasion of privacy, as well as life may be threatened even if your personal health information to be exposed or exploited illegally u-Healthcare services certification is essential. In 2012, Jeong proposed J-L patient authentication protocol that Initialization process, and patients using RFID technology separates the certification process. Jeong, such as the claim that the proposed protocol for reuse attacks, spoofing attacks, prevent information disclosure and traceability fire safety, but raises issues of security and operations efficiency. Therefore, in this paper, Jeong, such as the security of the proposed protocol and to prove the computational efficiency issues, and to enhance the safety and efficiency of RFID technology based on practical u-Healthcare services authentication protocol is proposed.

Barcode system has been used for many years in labors controlling & ready mixed concrete supplement in A/E/C industry However, it was not quite successful because ot its limitations in the field. The use of RFID system is getting important in the real world. RFID system substituted for barcode system in labor controling & ready mixed concrete supplement and it showed its potentialities in other major materials supply logistics and its possibilities In progress management of 4D system. This research shows RFID system's case study and its future directions in A/E/C industry.

Many RFID authentication protocols have been proposed to build a secure ubiquitous environment. However, existing protocols do not respond recent attacks appropriately and they perform many hash operations to authenticate a large number of tags. In this paper, we propose a hash function-based secure authentication protocol for improving efficiency in RFID system. The proposed protocol is safe to passive attacks and active attacks, and requires only 2 hash operations in a tag and 3 hash operations in a database. Accordingly, the proposed protocol is very effective in RFID system environment which is composed to low-cost tags and a database handling many tags.
