Recently, as digital communication technology is widely applied to the maritime field, large amounts of maritime data are being accumulated. Accordingly, attempts to create new value by applying data science and Artificial Intelligence(AI) technologies are emerging. Typically, Ministry of Oceans and Fisheries has been providing korean e-Navigation service since 2021 based on LTE-Maritime communication network, as well as R&D for creating value-added service through analyzing huge-sized maritime traffic data is underway. By the way, to do any data-based research, legal system, as a research infra, that researchers can get the data whenever they need is essential. This paper looked at types of data in maritime fields, checked related legal system about scientific analysis and utilization. It is confirmed that there are some legal factors which restrict its scientific analysis and utilization, and suggested ways of improvement to boost R&D using maritime data as a conclusion.

Data is an important resource to expect new value as 21st-century crude oil. In the shipping industry, despite the existence of numerous maritime data accumulated through ship operations, it was negligent in developing a business model with the data. This paper identified major demand sources and demand types based on the type and availability of maritime data surveyed through interviews with experts in the shipping industry and academia. Considering the characteristics and demands of these maritime data, this paper presented a private-type and public-interest business model. In the case of the private-type model, it creates additional added value by using maritime data and uses mainly ship internal data. The public-type model is to seek public safety and social benefits and mainly uses external data. A great synergy effect can be expected when combined with public services such as maritime survey, vessel traffic service, maritime environment management, and meteorological service. This study is expected to contribute greatly to the spread of the proposed business models throughout the shipping industry.

In this paper, we developed a prototype model accident management SMART-Navigation project. In order to develop a prototype model, we analyzed the status of maritime data exchange standard and procedure. We developed accident management prototype application schema, feature catalog and portrayal catalog in accordance with S-100 standard data model development procedure by collecting requirements related services and referring to related standards. In order to verify accident management prototype model, we test data set based on Gwang-yang Port. The prototype model and test data verified verification software, and it was confirmed that the designated symbol was displayed at the correct position through the S-100 simple viewer.

Maritime Big Data Linkage System is a system for linking maritime related internal and external data used in Korean e-Navigation. It is possible to create data acquisition, conversion, storage, analysis, management application service by technology of maritime data generated from inside and outside, and it can be configured and processed in units of components. It is also possible to monitor the flow of data defined by the workflow.. Through this study, it is expected that e-navigation service will be able to link data more efficiently and easily.

The Maritime Cloud is a technology that enables the seamless exchange of information between several communication links in the maritime domain. Although research on The Maritime Cloud security is still at an early stage, furthering this knowledge is vital to securing the marine environment. In this paper, we propose a method for secure data transmission through The Maritime Cloud domain. The proposed technique, based on the "secret sharing" scheme, is delivered through specifically-dedicated geocasting software. Thus, only authorized vessels can restore the original information. The proposed method is safe from so-called "sniffing" and "man-in-the-middle" attacks.

The IMO e-navigation strategy has requested a communication infrastructure providing authorized seamless information transfer between stakeholders. The Maritime Cloud is the term used to describe the concept of an infrastructure that support authorized, seamless information transfer, adding those elements, that are necessary to support the e-navigation domain. It is necessary to consider the study on maritime cloud security, but the study is still an early stage. In this paper, we propose a secure synchronization method for the maritime cloud services. The proposed method can be synchronize between the vessel based on the SH-Tree, and it has the advantage that there is no exposure information in the synchronization process.
