Future science fiction science film science fiction film can easily see the appearance of the futuristic inquiry. Even if a person does not open the door by force, the door is opened and closed by the system. Even now, such a door can be found easily. However, in the past, people who have not been able to perceive people have been used only in public places such as department stores and marts, where there are many people who are inundated. However, a lot of researches are being done now, and we are pursuing convenience in everyday life by integrating the image processing technology that has been developed and developed many times, by implementing the automatic door which is not infringed by the personal life and is impossible for anyone to access.

Since most of recently launched smart devices support NFC(Near Field Communication), RFID applications are tend to be replaced. For instance, previous RFID application areas such as entrance control, mobile e-ticket, electronic payment and et. al are subject to change using NFC. Due to the limitation of passive communication in RFID, it is impossible to cover all security requirements of authentication and authorization mechanism that wide areas of applications demand. Therefore authentication and authorization mechanism based on NFC is very attractive to such applications because active communication methods make it possible to be highly secure in authentication and authorization. In this paper, authors propose a new approach of secure authentication and authorization mechanism using NFC smart devices based on EAP(Extensible Authentication Protocol) and AAA(Authentication, Authorization and Accounting) protocols.

Iris recognition is a biometric technology that uses iris pattern information, which has features of stability, security etc. Because of this reason, it is especially appropriate under certain circumstances of requiring a high security. Recently, using the iris information has a variety uses in the fields of access control and information security. In extracting the iris feature, it is desirable to extract the feature which is invariant to size, lights, rotation. We have easy solutions to the problem of iris size and lights by previous processing but there is still problem of iris feature extract invariant to rotation. In this paper, To improve an awareness ratio and decline in speed for a revision of rotation, it is proposed that the iris recognition method using Zernike Moment and Daubechies Wavelet. At first step, the proposed method groups rotated iris into similar things by statistical feature of Zernike Moment invariant to a rotation, which shortens processing time of iris recognition and looks equal to an established method in the performance of recognition too. therefore, proposed method could confirm the possibility of effective application for large scale iris recognition system.

RFID could be applied in the various fields such as distribution beside, circulation, traffic and environment on information communication outside. So this can speak as point of ubiquitous computing's next generation technology. However, it is discussed problem of RFID security recently, so we must prepare thoroughly about RFID security for secure information. In this paper, we proposed a method which could protect private information and ensure RFID's identification effectively storing face feature information on RFID tag. Our method which is improved linear discriminant analysis has reduced dimension of feature information which has large size of data. Therefore, we can sore face feature information in small memory field of RFID tag. Our propose d algorithm has shown 92% recognition rate in experimental results and can be applied to entrance control management system, digital identification card and others.

Iris recognition is a biometric technology which can identify a person using the iris pattern. Recently, using iris information is used in many fields such as access control and information security. But Perform complex operations to extract features of the iris. because High-end hardware for real-time iris recognition is required. This paper is appropriate for the embedded environment using local gradient histogram embedded system using iris feature extraction methods have implement. Experimental results show that the performance of proposed method is comparable to existing methods using Gabor transform noticeably improves recognition performance and it is noted that the processing time of the local gradient histogram transform is much faster than that of the existing method and rotation was also a strong attribute.

Terror for airplane, airport and passengers of the problems is being threat over the world. and since 9.11 terror of 2001 year, many countries have endeavored to prevent terror and have manipulate airport security part as important field. Especially, The U.S.A made Transportation security Administration in Homeland security adminstration and strongly execute for policies related anti-terror. many countries over the world enforce airport and airplane security facilities with science-technology contents. and with security exploitation for the passengers and freight security inspection level enforcement, many countries also make effort to interupt aviation terror threat. In this process, in the center of developed countries that need science-technology contents adaption, much budget and personals are invested and exploited a security inspection instrument and complimented of many facilities As a result, according to the development of science-technology, prevention of Terror have much developed. The contents using intelligence-communication technology inevitably needed on the goal of terror prevention and safty. From simple monitoring for the people who come in and out airport to boarding process and inspection for the freight, security inspection process for the passengers, bio information input, confirmation, of the level that there is no cases of adaption of contents, The reality have generalized of using contents. The study is going to research contents application situation.

An information-oriented basis in today's society has been changing fast, and the desire for connectivity has caused an exponential growth in wireless communication and sensor network. Sensor networks using RFID, in particular, have led this trend due to the increasing exchange of data in Ubiquitous such as the home RF, access control system, U-Healthcare, and Logistics information Systems. Also, the RFID when it applies a technique, is able to raise the stability of shipping as controling the mobile course and an entrance and exit of the crews an well as previously preventing an accident from shipping. In this paper, we designed and implemented personnel control system using UHF-RFID in vessels which shows through host PC reading and writing tag.

Iris recognition is a biometric technology which can identify a person using the iris pattern. Recently, iris information is used in many fields such as access control and information security. It is important for the iris recognition system to extract the feature which is invariant to changes in iris patterns. Those changes can be occurred by the influence of lights, changes in the size of the pupil. In this paper, we propose a novel method based on vector summation of gradient orientation vectors. Experimental results show that the proposed method reduces processing time with simple vector calculation, requires small feature space and has comparable performance to the well-known previous methods.
