METHOD AND APPARATUS FOR ENSURING CONTINUITY AND FORGERY PREVENTION OF EXCHANGE DATA BETWEEN SHIPS AND LAND STATIONS BASED ON BLOCKCHAIN AND MARITIME DIGITAL PLATFORM SYSTEM

摘要

The present invention relates to a method and apparatus for ensuring continuity of exchange data between a blockchain-based ship and a land station and preventing forgery and falsification, and a maritime digital platform system using the same, and an exchange between a blockchain-based ship and a land station according to an embodiment of the present invention The method for ensuring continuity of data and preventing forgery includes: receiving encrypted hash data from a maritime digital platform device, and calculating a first hash value by decrypting the received encrypted hash data; Calculating a second hash value by converting block data received in block units by requesting the maritime digital platform device into a hash code; checking whether the received block data is forged or falsified by comparing the calculated first hash value with the calculated second hash value; and selectively retransmitting the forged and forged block data to the maritime digital platform device.
