With various sensors and communications capabilities, the Internet is growing larger as the internet can communicate with the Internet. Given the growing vulnerability of the internet market, the development of security and security is increasing, and the development of the internet is actively evolving and the development of the internet is actively being carried out. In particular, it is required to introduce lightweight and secure authentication schemes, especially those that are difficult to use due to the difficulty of using authentication schemes. Thus, the safety of the secure authentication system of the Internet is becoming very important. Therefore, in this thesis, we propose certification technologies on secure objects to ensure correct, safe communication in the context of the internet context.

The purpose of this study was to ascertain new policies fo the development of the Korean Hospital Accreditation Program (HAP) by comparing and reviewing the domestic HAP of Korea, the U. S. and Australia as well as the International Accreditation Program of the International Society for Health Care Quality. The results of this study are as follows. First, it is necessary to improve the standards of the HAP such as 'patient and community centered standards' and 'staffing related standards'. Second, it is necessary to strengthen patient safety through the HAP. Third, the linkage among the HAP, clinical indicators and patient experience evaluation should be strengthened. Fourth, the competencies of surveyors should be improved. Fifth, the HAP of small and medium hospitals also needs to be vitalized. Sixth, it is necessary to improve the disclosure of the healthcare quality evaluation results. The findings of this study can be used as a basis to improve the Korean HAP.

Blockchain technology provides distributed trust structure; with this, we can implement a system that cannot be forged and make Smart Contract possible. With blockchain technology emerging as next generation security technology, there have been studies on authentication and security services that ensure integrity. Although Internet-based services have been going with user authentication with password, the information can be stolen through a client and a network and the server is exposed to hacking. For the reason, we suggest blockchain technology and OTP based authentication mechanism to ensure integrity. In particular, the Two-Factor Authentication is able to ensure secure authentication by combining OTP authentication and biometric authentication without using password. As the suggested authentication applies multiple hash functions and generates transactions to be placed in blocks in order for biometric information not to be identified, it is protected from server attacks by being separate from the server.

With the development of the Internet, user authentication technology that proves me online is improving. Existing ID methods pose a threat of personal information leakage if the service provider manages personal information and security is weak, and the information subject is to the service provider. In this study, as online identification technology develops, we propose a DID-based self-authentication model to prevent the threat of leakage of personal information from a centralized format and strengthen sovereignty. The proposed model allows users to directly manage personal information and strengthen their sovereignty over information topics through VC issued by the issuing agency. As a research method, a self-authentication model that guarantees security and integrity is presented using a decentralized identifier method based on distributed ledger technology, and the security of the attack method is analyzed. Because it authenticates through DID Auth using public key encryption algorithms, it is safe from sniffing, man in the middle attack, and the proposed model can replace real identity card.

Using a smartphone allows quick and easy authentication and payment. However, smartphone security threats are evolving into a variety of new hacking technologies, and are changing to attacks specific to the mobile environment. Therefore, there is a demand for an authentication method suitable for a mobile environment. In order to solve security weaknesses in knowledge-based authentication, many companies provide two-step authentication services such as OTP(One Time Password) to provide authentication services such as finance, games, and login. Although OTP service is easy to use, it is easy to duplicate random number table and has a disadvantage that can be reused because it is used as valid value within time limit. In this paper, we propose a mechanism that enables users to quickly and easily authenticate with high security using the authentication method that recognizes special characters through smartphone's dedicated application.

In this paper, we propose a personalized user authentication system (PUAS) that can be used in multiple stages in user authentication by customizing the password keyword to be used in user authentication. The proposal concept is that the user oneself defines the password keyword to be used in user authentication so as to cope with a passive retransmission attack which reuses the password obtained when the server system is accessed in user authentication. The authentication phase is also designed so that it can be expanded in multiple stages in a single step. Also, it is designed to store user-defined password related information in an arbitrary encrypted place in the system, thereby designing to disable the illegal access of the network. Therefore, even if an intruder accesses the system using the proposed system, it is possible to generate personal authentication information by generating a password keyword through unique personal information possessed only by an individual and not know the place where the generated authentication information is stored, It has a strong security characteristic.

In the rapidly changing society since the Fourth Industrial Revolution, the cultivation of convergence talents that can solve complex problems is emerging as an important issue. The purpose of this study is to propose the core competencies required to establish the program learning outcomes of the engineering and education curriculum, which is the accreditation standard of engineering education proposed by ABEEK(Accreditation Board for Engineering Education of Korea). Case study methodology was applied to achieve the purpose of the study. The case of analysis is design and software convergence majors of domestic and foreign universities. The educational objectives and course syllabi were analyzed. As a result of the research, four core competencies to be achieved in the design and software convergence majors were derived in addition to the ten program outcomes presented by ABEEK. New core competencies are convergence ability, creative thinking, entrepreneurship, and design ability. The result of this study is expected to contribute to the development of the evaluation system for the convergence engineering education field.
