Study on ocean intelligence service security utilizing blockchain technology

The environment of ocean having special conditions is at risk of frequent accidents. For safer use of ocean environment, the whole world is attempting to graft the state-of-the-art technology with the introduction of lots of institutions such as international treaties. In the meantime, with the development of the state-of-the-art IT technology and increase in superhigh speed network establishment, the era of the Internet of Things is opening, and there are increasing cases of fusion with IT in the ocean area. Accordingly, at a time when security for data is especially required, blockchain technology is one of the major alternatives. This study examined application possibility and limits of blockchain technology through ocean space information's security treatment experiment utilizing blockchain technology. For the experiment, GML data which has S-10X electric navigation chart standard structure was used. The experiment results suggested that descrambling of ocean space information utilizing blockchain technology was successfully conducted for safe protection, and it is expected that it would be utilized for ocean space information of other types.
