RFID system is the contact-less recognition technology and use for distribution system, environment, transport, security and so on. However, it may create many security relevant problems such as privacy because constraints of RFID communication environment. So several methods of resolving these problems have been proposed. Recently, Shin and Park proposed an efficient RFID authentication protocol with protecting user's privacy using hash function and exclusive-OR.. But Ahn and Bu et al. poia problem that a attacker can to masquerade as malicious reader because their protocol can't providing mutual authentication.nted out weakness of Shin and Park's protocol and proposed more secure and efficient protocol. Unfortunately, Ahn and But's protocol has In this paper, We propose an improved RFID authentication protocol providing mutual authentication. The proposed protocol has advantages that providing mutual authentication between a tag and a reader, secure against replay attack and spoofing attack. Also, it guarantees anonymity of RFID tag and secure against location tracking attack by collusion of malicious readers.

A great number of RFID authentication protocols have been proposed for the secure RFID system. These are typically divided into three types according to primitive that they use : Hash-based, Re-encryption based, and XORing-based protocol. The well-known attacks in RFID system are eavesdropping. impersonating, location tracking, and so on. However, existing protocols could not provide security against above attacks, or it was not efficient to search for tags on database. Therefore, in this paper we present a protocol which is secure against above attacks by using hash function and makes Database search tags easily by attaining the state information of previous session through the shared values with all tags and database.

Nowadays there are many studies and there's huge development about USN/RFID which have great developmental potential to many kinds of applications. More and more real time application apply USN/RFID technology to identify data collect and locate objects. Wide deployment of USN/RFID will generate an unprecedented volume of primitive data in a short time. Duplication and redundancy of primitive data will affect real time performance of application. Thus, security applications must filter primitive data and correlate them for complex pattern detection and transform them to events that provide meaningful, actionable information to end application. In this paper, we design a ECA Rule system for security monitoring of exhibition. This system will process USN/RFID primitive data and event and perform data transformation. It's had applied each now in exhibition hall through this study and efficient data transmission and management forecast that is possible.

Radio Frequency Identification (RFID) is a technology for automated identification of objects and people. RFID may be viewed as a means of explicitly labeling objects to facilitate their "perception" by computing devices. RFlD systems have been gaining more popularity in areas especially in supply chain management and automated identification systems. However, there are many existing and potential problems in the RFlD systems which could threat the technology s future. To successfully adopt RFID technology in various applications. we need to develop the solutions to protect the RFID system s data information. This study investigates important issues related to privacy and security of RF1D based on the recent literature and suggests solutions to cope with the problem.

Recently, study on RFID Tag Searching technique which is used to find a specific tag in particular tag group were developed continuously. RFID tag searching technique can be applicate in various fields such as product management, finding children, and electronic anklet. To implement a RFID tag search system, RFID tag searching protocol should be considered various security threats such as reader and tag tracking, privacy, etc. For implementing a safe RFID tag lookup system, it is important to consider the potential security threats such as the tag tracking problem, and the privacy of the owner of the tag reader problem. There exists an RFID tag lookup system that satisfies a few security requirements, but the privacy of the owner of the tag reader problem has still been left unsolved, and even if it were solved, it requires a considerable amount of cryptographic operations to be performed which results in a decrease in performance. This paper proposes a system that does not degrade the performance while solving the privacy of the owner of the tag reader problem.

The proposed system can achieve more safety of RFID system with the 2-step authentication procedures for the enhancement about the security of general RFID systems. After it has authenticated RFID tag, additionally, the proposed system extract the characteristic information in the user image for acquisition of the additional authentication information of the user with the camera. In this paper, the system which was proposed more enforce the security of the automatic entrance and exit authentication system with the cognitive characters of RFID tag and the extracted characteristic information of the user image through the camera. The RFID system which use the active tag and reader with 2.4GHz bandwidth can recognize the tag of RFID in the various output manner. Additionally, when the RFID system have errors. the characteristic information of the user image is designed to replace the RFID system as it compare with the similarity of the color, outline and input image information which was recorded to the database previously. In the experimental result, the system can acquire more exact results as compared with the single authentication system when it using RFID tag and the information of color characteristics.

RFID, a non-contact wireless identification technology is being noticed as a technology to alternate barcode system in distribution industry and general industry. Despite of merit of RFID, there are issues to be solved for practical use. One of them, which are most important, is resolution of user's information protection. RFID system without security function bears risk exposing personal data and user's privacy. In this paper, we propose mutual authentication protocol for RFID system in order to solve this security issue. This study aimed to protect user's privacy by providing dynamic ID for tag through authentication protocol safe from security threats. Information being transmitted between backend, reader and tag has no direct connection with ID of tag, and it conducts authentication process using one-way hash function, which prevents attacker's obtaining of tag information using information being transmitted.

In times past, simple numeric password was the commonly used method in security system. For complement this method, the security system using biometric information is appeared. But it usually uses the scheme to utilize portion of biometric information, and has limited application fields. This biometric security system has low reliability because of some problems such as steal, robbery, and so on. Furthermore, it is associated secondary crime as leaking personal information. For this reason new security system using the unique individual biometric is required. In this paper, we propose the security scheme which used face image and iris analysis. While face image processing for specific person identification, it calculate some feature points of face image and iris's features in our proposed scheme. After person identification applying RFID tags in doorway, several feature information is extracted from camera image, and these compare with registered information of our system for final identification.
