In the Role-Based Access Control(RBAC) model access to resources is based on the role the user holds within the organization. But, the users in RBAC gain access to predetermined roles and permissions. Thus, the policy in RBAC does not achieve desired results in emergency situations that users should sometimes gain access to resources not authorized in normal situations. In this paper, we propose an Permission-based Emergency RBAC(ERBAC) to enhance the flexibility of RBAC for managing the system in emergency situation. The proposed model uses a permission-based authorization mechanism to maintain the principle of least-privilege. and includes BTG-SSD, BTG-DSD and BTG-Binding constraint to control user access in emergency situation. Then, it uses an administrative model to manage large ERBAC systems and alleviate administrator’s burden. This approach also makes BTG more flexible, allowing for fine-grained facility-specific policies, and even automates auditing in many situations. Finally, it is illustrated with medical scenarios so as to analyze the validity of proposed model specifications.

The Internet of Things, the core of the Fourth Industrial Revolution, is growing by applying various technologies to various fields. Among them, smart home systems that apply IoT technology to home environments are actively being researched, and the home hub market, which is a communication medium for smart homes, is also developing at the same time. However, the security damage from cyber attacks, which are vulnerabilities in IoT technology, is also increasing in proportion to these developments. In this paper, mirror is implemented as an IoT service hub. It can be used in any space where a mirror is installed, and gesture recognition allows control of existing infrared-based devices as well as certain compatible devices. In addition, the system to solve security problems was implemented by applying AES algorithms between all data communications.

Among them, smart home systems that apply IoT technology to home environments are being actively studied. The home hub market, a means of communication for smart homes, is also developing at the same time. As the home hub market develops, security threats are also increasing accordingly. In this paper, 'Smart Home Mirror' is implemented by combining mirror and IoT technologies so that users can use them to communicate with smart home applications and other devices. To meet security issues, users in it are recognized by using face recognition technology and AES between all data communications in it is applied. The proposed device’s usefulness is approved by implementing it in smart home environments.

As modern people's interest in health grows, wearable healthcare-related technologies that can collect biometric information and receive health-related services regardless of time and place are developing. This paper proposes the healthcare system based on voice recognition function. Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.
