Current technologies on digital rights management (DRM) have focused on security and encryption as a means of solving the issue of unauthorized copying, that is, locking the content and limiting its distribution to only purchasers. But, illegal content copy should be protected not only from purchasers but also from other principals such as media distributors and content providers. In this paper, we designed and implemented end-to-end digital lights management system that can cover a content protection on the overall value-chains of content distribution. Proposed system provides content protection and secure management of digital rights in creator, provider, and distributor like in purchaser. Accordingly it can provide an environment protecting each principal's digital rights and prohibiting illegal usage of content.

As the elderly population is becoming an aging society, the elderly are experiencing many problems. Social security costs for the elderly are increasing and the un-linked social phenomenon is emerging. Thus, the social infrastructure and welfare system established in the past economic growth period are in danger of not functioning properly. People socially isolated or with chronic diseases among the elderly are exposed to various accidents. Thus, an active healthcare management service is imperative. Additionally, in the event of a dangerous situation, the system must have ways to notify guardians (family or medical personnel) regarding appropriate action. Thus, in this paper, we propose the smartphone-based healthcare and emergency response service platform. The proposed service platform aggregates movement of relevant data in real-time using a smartphone. Based on aggregated data, it will always recognize the user's movements and current state using the human motion recognition mechanism. Thus, the proposed service platform provides real-time status monitoring, activity reports, a health calendar, location-based hospital information, emergency situation detection, and cloud messaging server-based efficient notification to several subscribers such as family, guardians, and medical personnel. Through this service, users or guardians can augment the level of care for the elderly through the reports. Also, if an emergency situation is detected, the system immediately informs guardians so as to minimize the risk through immediate response.

Organisations worldwide strive to develop their management systems for business functions, ranging from quality and environment to safety, information security and social responsibility. During the latest decade a considerable amount of these efforts has been concentrated on introducing and applying standards such as the ISO 9001 and ISO 14001. The need for Integrated Management Systems (IMS) often arises as a result of decisions to implement Environmental Management System (EMS) and/or an occupational health and safety management system in addition to a Quality Management System (QMS). At the end of 2003, approximately 3200 organisations in Sweden had an ISO 9001 certificate, and approximately 3400 organisations had a certificate based on an EMS. Dealing with separate management systems and ensuring that they align with the organisation's strategies and goals, has proved difficult. Owing to the large number of organisations certified according to multiple types of systems, an increasing number of organisations are establishing IMS. There are examples of companies, which chose to integrate EMS and QMS into a co-ordinated implementation approach, and although sparse, the research within this area indicates potential benefits of using an integrated approach. This paper presents both a theoretical and an empirical investigation with the aim to elucidate problems related to the integration of management systems. Furthermore, the paper will present recommendations for succeeding in such integrations and, hence, contributing to an increased understanding on how IMSs should be designed and implemented.

As natural language processing technology using machine learning develops, a Smart Home Network Service (SHNS) is drawing attention again. However, it is difficult to apply a standardized authentication scheme for SHNS because of the diversity of components and the variability of users. Blockchain is proposed for data authentication in a distributed environment. But there is a limit to applying it to SHNS due to the computational overhead required when implementing a proof-of-work system. In this paper, a lightweight work proof system is proposed. The proposed lightweight proof-of-work system is proposed to manage block generation by controlling the work authority of the device. In addition, this paper proposes an access control scheme for SHNS.
