The acceptance of unsolicited proposals (a private-initiated process) has been viewed by several governments as a means of encouraging innovative initiatives. However, the ramifications of this mechanism are still poorly understood. This paper analyzes a framework used by the Taiwanese government to evaluate unsolicited proposals. Taiwan's experience demonstrates the need for an improved framework in which key issues such as building consensus, maintaining a transparent procurement process, ensuring sufficient competition, and protecting intellectual property rights shall be addressed. In addition, the case study suggests that the roles of participants, the relationships and interfaces of activities, information flows, and decision making points should all be well defined. Some fundamental differences between solicited and unsolicited proposals are also discussed.

The Public Private Partnership/Private Finance Initiative (PPP/PFI) schemes have made the private sector become a major participant involved in the development of infrastructure systems along with the government. Due to more integrated efforts among project participants and longer concession period, PPP/PFI projects are inherently more complex and risky. It is therefore very important to proactively manage the risks involved throughout the project life cycle. Conventional risk management strategies sometimes ignore managerial flexibility in the planning and execution process. This paper starts with a revised risk management framework which incorporates the real option concept. Following the presentation of the framework, a new risk classification is proposed which leads to different ways of structuring options in a project according to the stage of the project life cycle. Finally, the paper closes by discussing other issues concerning option modeling and negotiation.

Virtual Reality(VR) data in VR environments like Manufacturing industries are often created jointly by many creators. It is then necessary to provide protection of the joint-creatorship and the creatorship of each participating creator. This paper proposes Multiple Digital Watermarking Framework(MDWF) to solve the problem of joint-creatorship. The proposed framework, MDWF, makes use of 3D private watermarking technology and a novel key sharing protocol for joint-creatorship verification. MDWF embeds 3D private multiple watermarks for the creatorship of each participating creators in a non-overlapping manner during the creation process. After key agreement of all private keys, MDWF embeds an additional 3D private watermark for the joint-creatorship. Therefore MDWF successfully handles the creatorship dispute among creators. That is, each participation creator can prove his/her partial creatorship as well as joint-creatorship by MDWF. In addition, MDWF can solve the collusion problems because shared secret key(SSK) can be made by every users.

A Systematic Wealth Management Framework (SWMF) was developed as a private banking management tool to enable more integrative personal finance management of personal wealth. It is a reference model that provides an unified framework for development, operation, and management and makes provision for personal financial services in today's complex financial environment. This study suggested some practical results from banks and insurance companies that have established SWMF as the differentiation business strategy for wealthy customers. The focus of this manuscript is on capturing the methodological approach most financial institutions in Korea adopted to execute new e-finance planning and implementation based on the SWMF. The alignment between the wealth management business goals and information system architecture at an organization constitutes the main theoretical basis of the study. Relevant discussions are made on the wealth management framework as a general business model for financial industry, on the functional relationship between new information systems and business organizations. Finally, lessons learned from the SWMF implementation are discussed.

Globally, under the leadership of advanced ICT countries, the private sector is promoting various policies to promote the digital transformation of public services. Looking at the research trend, design of public service indicators, development of evaluation system, and empirical research are being carried out steadily, but there are insufficient research cases on models in which the private sector participates in the planning, development, and operation of public services. In this study, Private-centric digital public service suitability evaluation indicators were discovered through interviews with experts in various fields, and weights for each indicator were analyzed through AHP evaluation. In addition, by applying the analysis results to 18 digital public services on a trial basis, the importance and priority of evaluation indicators for each service were derived, and at the same time, the evaluation framework was designed and applied to diagnose implications. As a result of the study, 'social utility', 'corporate acceptability', and 'public acceptability' were selected as the top three indicators of suitability evaluation. At this time, it was analyzed that the weight of the 'company acceptability' index, which includes sub-indices such as 'service profitability', 'service scalability', and 'private initiative possibility', was the highest among the three top indicators. As a result of the demonstration for public services, "IoT facility unmanned remote monitoring service", "blockchain real estate transaction service", and "digital twin disaster prediction service" were evaluated as the most suitable public services for the transition to the private sector.

현재 연속성관리체계로 가장 널리 사용되고 있는 BCM(Business Continuity Management) 또는 BCP(Business Continuity Planning)을 기반으로 한 금융분야의 모범규준 및 구축사례는 많이 있었으나, 민간의 시설관리 분야 및 공공기관의 국가기반 체계에 실질적으로 적용 가능한 표준화된 연속성관리체계 구축 프레임워크에 대한 연구는 미미한 실정이다. 따라서 본 연구에서는 국내외 연속성관리 프레임워크의 비교와 시설관리 분야의 특성을 고려한 연속성관리 구성요소의 검토를 통해 민간 시설관리 분야 및 공공기관에 적합한 시설관리 분야의 연속성관리체계 구축 프레임워크를 모색하는 연구를 하고자 한다.

As data sharing increases explosively, such information encoded in QR code is completely public as private messages are not securely protected. This paper proposes a new 'PROMISE' framework for hiding information based on the QR code projection matrix by using image segmentation without modifying the essential QR code characteristics. Projection matrix mapping, matrix scrambling, fusion image segmentation and steganography with SEL(secret embedding logic) are part of the PROMISE framework. The QR code could be mapped to determine the segmentation site of the fusion image as a binary information matrix. To further protect the site information, matrix scrambling could be adopted after the mapping phase. Image segmentation is then performed on the fusion image and the SEL module is applied to embed the secret message into the fusion image. Matrix transformation and SEL parameters should be uploaded to the server as the secret key for authorized users to decode the private message. And it was possible to further obtain the private message hidden by the framework we proposed. Experimental findings show that when compared to some traditional information hiding methods, better anti-detection performance, greater secret key space and lower complexity could be obtained in our work.

This paper presents a hybrid blockchain-based Identity Management Framework for devices in Microgrid. It incorporates the use of a Public and Private Blockchain platform to store and authenticate Microgrid device identities. It also emphasizes the shared responsibility of the manufacturers to provide the first layer of authentication for the devices they produce. Identities of each device are stored in the private and public Blockchain and authenticated using physically unclonable functions (PUF) and cryptographic functions.
