In this paper, we propose the access control system based bluetooth using the MAC address of the smart device. Access control system that propose compares the smart device MAC address entry and exit and MAC address that is registered with the server. Depending on whether the match was compared, access control is performed. Result of the experiment, control of door is possible only by bluetooth pairing of the bluetooth module and smart device. Therefore, it does not require access to another tool.In addition, Action for access approval is omitted. Therefore, the access authorization procedure is simplified compared to existing access control systems, it is possible to improve the convenience.

WebDAV is an IETF standard protocol which supports asynchronous collaborative authoring on the Web. The WebDAV Access Control Protocol provides various methods of controlling the resources on a WebDAV server and their properties, helping high-level group activities to be performed through the WebDAV server. In this paper, to provide high level collaboration, we introduce a technique for managing access control over WebDAV resources through the WebDAV Access Control Protocol and describe the development of an access control manager for the CoSlide Collaborative system based on the technique. To provide users with the access control features in an easily understandable manner, the developed technique presents the privileges for performing WebDAV methods instead of the standard privileges in the WebDAV Access Control Protocol. In addition, we present the facility for detecting conflicts between new access privileges on resources and old access privileges on them. We applied the method-based access control management technique to the CoSlide collaborative system. The developed access control manager enables us to create group workspaces with flexible access control strategies for group members and resources.

Decentralized Identifier (DID) technology is a technology that uses blockchain technology to prove an individual's identity through information owned by the individual rather than through a central system. In this paper, we would like to present an access control system using decentralized identifier technology. The access control system using decentralized identifier technology (DID access control system) is a system that allows users to verify their identity from the DID blockchain server through their smartphone (mobile employee ID) and access when they are confirmed to be registered in the access control system. Through this, access control can be managed only by verifying identification with smartphones (mobile employee ID) and DID blockchain servers without having to store information to prove an individual's identity in the access control system.

In recent years, there has been developed systems such as a surveillance system and access control using a face recognition function instead of a password or an RFID chip, thereby reducing the risk of falsification. Moreover, deep learning technology has been applied to real-time face recognition technology in video, so it makes possible the development of access control system that improves the accuracy of recognition and efficiency of management. In this paper, we propose a real-time access management system based on face recognition using ResNet. The system is based on web server, which make it possible to manage the access by recognizing the person of the image through the camera and access information stored in the database. It can be accessed by a user application to receive various information. The implemented system identifies a person in real time and allows access control by accurately distinguishing whether they are members or not, and the test results can recognize in 0.2 seconds. The accuracy of recognition rate is up to about 97% depending on the experiment environment. With this system, access can be managed quickly and effectively, even many people rush to it.

SELinux, security operating system, is the security system which implements mandatory access control using linux security module on the traditional linux kernel supporting discretionary access control. But intrusion detection and logging are lacked when system intrusions are happened. This study proposes a SELinux security kernel which performs detection of access violation and privilege restriction using dynamic access control. It detects the intrusion using security check when the abnormal access of system is happened, and dynamically changes the system privilege for the intruder through privilege restriction. Finally we prevent reintrusion and explain the result of experiment.

In industries that are operating various enterprise systems, new systems are integrated and operated in accordance with each period. In particular, when a new system is to be integrated, one of the major considerations is the single sign-on part for integrating and operating the authentication. To implement this authority system using role-based access control method, an extension method for access control method is needed. Therefore, in this paper, we design an extended role-based access control model for interworking with legacy authority system and provide its APIs. The extended role-based access control model is a model in which external authority information, which holds authority information in the authority information, is added. And we describe operations that the REST Web APIs are based on these models. In this paper, the method is described in the back-end APIs and can be implemented as an operation of an extended role-based access control system based on the method.

As per increasing research interest in the field of collaborative computing in recent year, the importance of security issues on that area is also incrementally growing. Generally, the persistency of collaborative system is facilitated with conventional authentication and cryptography schemes. It is however, hard to meet the access control requirements of distributed collaborative computing environments by means of merely apply the existing access control mechanisms. The distributed collaborative system must consider the network openness, and various type of subjects and objects while, the existing access control schemes consider only some of the access control elements such as identity, rule, and role. However, this may cause the state of security level alteration phenomenon. In order to handle proper access control in collaborative system, various types of access control elements such as identity, role, group, degree of security, degree of integrity, and permission should be taken into account. Futhermore, if we simply define all the necessary access control elements to implement access control algorithm, then collaborative system consequently should consider too many available objects which in consequence, may lead drastic degradation of system performance. In order to improve the state problems, we propose a novel access control framework that is suitable for the distributed collaborative computing environments. The proposed scheme defines several different types of object elements for the accessed objects and subjects, and use them to implement access control which allows us to guarantee more solid access control. Futhermore, the objects are distinguished by three categories based on the characteristics of the object elements, and the proposed algorithm is implemented by the classified objects which lead to improve the systems' performance. Also, the proposed method can support scalability compared to the conventional one. Our simulation study shows that the performance results are almost similar to the two cases; one for the collaborative system has the proposed access control scheme, and the other for it has not.
