We propose to design a Holochain-based security and privacy protection system for resource-constrained IoT healthcare systems. Through analysis and performance evaluation, the proposed system confirmed that these characteristics operate effectively in the IoT healthcare environment. The system proposed in this paper consists of four main layers aimed at secure collection, transmission, storage, and processing of important medical data in IoT healthcare environments. The first PERCEPTION layer consists of various IoT devices, such as wearable devices, sensors, and other medical devices. These devices collect patient health data and pass it on to the network layer. The second network connectivity layer assigns an IP address to the collected data and ensures that the data is transmitted reliably over the network. Transmission takes place via standardized protocols, which ensures data reliability and availability. The third distributed cloud layer is a distributed data storage based on Holochain that stores important medical information collected from resource-limited IoT devices. This layer manages data integrity and access control, and allows users to share data securely. Finally, the fourth application layer provides useful information and services to end users, patients and healthcare professionals. The structuring and presentation of data and interaction between applications are managed at this layer. This structure aims to provide security, privacy, and resource efficiency suitable for IoT healthcare systems, in contrast to traditional centralized or blockchain-based systems. We design and propose a Holochain-based security and privacy protection system through a better IoT healthcare system.

4차 산업혁명의 몰입과 함께 산업의 전반적인 흐름이 ICT 기반의 비즈니스 환경으로 나아감에 따라 의료산업에도 환경변화가 일어나고 있다. 공공재 성격을 지닌 의료산업에서는 의료서비스의 신뢰성과 지속성을 요구하고 있으나, 스마트 환경으로 전환하기에 기존 시스템들의 호환성, 확장성 문제로 인하여 보안에 대한 도입이 늦춰지고 있다. 이에 따라, 본 연구에서는 신속하게 스마트 의료환경에서 보안체계를 구축하기 위하여, 필요로 하는 보안기술을 도출, 분석하고 도입하기 위한 이해관계자들이 관심을 가져야하는 부분과 역할에 대하여 설계하였다. 이를 통하여 의료보안체계를 구축하기 위한 이해관계자들의 다차원적인 노력에 대하여 확장성 있는 가능성을 제시하였다.

인터넷의 발달로 개인정보의 수집 및 이용이 일상화됨에 따라 개인정보의 침해가 급속도로 확대 되고 있다. 의료분야에 대한 개인정보보호에 대해서는 '정보통신망이용촉진 및 정보보호 등에 관한 법률'등에 체계적으로 규정되어 있으나, 법적용 대상이 정보통신 서비스 제공자 위주로 규정되어 의료분야에 적용하는 데 한계가 있다. 때문에 본 논문에서는 국내 의료기관이 전자의무기록 시스템에 보안을 적용하기 위해 우선적으로 선행되어야 할 개인의료정보 보호방안에 대해 정의하고, 적용근거를 위한 법 제도의 검토사항을 제시하였다. 또한, 전자의무기록에 대한 전자서명의 구체적인 적용방안을 예시하여 의료분야에 있어서 보안적용을 위한 기준을 제시하였다.

South Korea is not a wasteland of publicly funded health care-instead, it has a good medical social security system known as the national health insurance (NHI). The NHI of Korea has three unique features; (1) low premiums, low insurance fees, and low coverage; (2) obligatory designation of medical institutions; (3) and allowance of non-benefit services. These features have made hospitals and doctors interested in profit-seeking. However, the commercialization of medical institutions has taken place in both private- and public-established sectors. A basic problem of commercialization is the co-existence of the obligatory designation of medical institutions and non-benefit services. The problem became worse in the Kim Dae-Jung government because it officially permitted non-benefit services. Since 2000, the Korean government has consistently pursued benefit extension policies, but the coverage rates of the NHI have stagnated. In addition, premiums and current medical expenses have markedly increased because policy-makers have emphasized accessibility to the NHI, while ignoring important principles of medical social security such as a needs-based approach and patient-referral system. In order to resolve the commercialization problem, the obligatory designation of medical institutions to the NHI should be changed to a contract system, and non-benefit services should be prohibited at NHI institutions. We must re-establish the patient-referral system via a needs-based approach. We also need to build a primary healthcare system and public health policies. We should make a long-term plan for healthcare reform.

The purpose of this study is to derive periodical characteristics of the policy for the elderly in Japan by investigating the changes of social security system. The target period of 1946~2000 in Japan was divided into 3 periods for the understanding of periodical characteristics in the focuses of medical, welfare and pension system for the elderly; establishment of concept for the social security and welfare of Japan(1946,1950), appearance of social security system and the elderly problem(to late 1960's), infra construction for aging society(to late 1980's), development and reappraisal of practical policy for the elderly(to late 1990's). It is expected that this paper could provide basic data for the elderly-related policy making in our country.

This paper analyzed four different perspectives on health care reform in Korea in terms of the basic values, formulated problems and reform plans, implementation methods, and supporting groups. The medical security plan was insisted by social security specialists and social activists focusing on the integration of medical insurance coops in order to enhancing equity and right of the people. However, its perspective was limited to promoting security instead of reforming health care system. The government proposed the health care reform plans in 1994 and in 1997, focusing on promoting efficiency by remedying many problems in health care delivery system. However, its implementation was not successful due to the lack of organizational and financial supporters. Recently, two opposite proposals were issued. The market reform plan paid attention to revitalizing the market function to promoting efficiency by allowing hospitals to treat private patients instead of applying the medical insurance regulation. The government reform plan focused on intensifying governmental planning and intervention in the health care sector in order to removing inefficiency and promoting equity with the supports of social activists and labor unions. Finally, this paper proposed an alternative plan to promote harmonious social relationship between actors in the health care system.

The cyber attacks on the computer system in nowadays are focused on works that do not operate specific application. The main key point that we protect information security system has an access control to keep an application. Most of system has a main function to protect an infrastructure such as hardware, network and operating system. In this paper, we have presented an intrusion tolerance system that can service an application in spite of cyber attacks. The proposed system is based on the middle ware integrating security mechanism and separate function of application and intrusion tolerance. The main factor we use security system in nowadays is service to keep a persistency. The proposed intrusion tolerance system is applicable to such as medical, national defense and banking system.

The use of a mobile agent in hospital environment offers an opportunity to deliver better services for patients and staffs. Furthermore, medical errors will be reduced because M-health system helps to verify the medical process. Optimized security protocols and mechanisms are employed for the high performance and security. Finally, a challenge in the near future will be converge the integration of Ubiquitous Sensor Network (USN) with security protocols for applying the hospital environment. We proposed secure authentication and protocol with Mobile Agent for ubiquitous sensor network under healthcare system surroundings.
