BMWS MATHOD FOR VERIFYING BALLAST WATER TREATMENT RESULTS BASED ON BLOCKCHAIN FOR BWMS OPERATING SHIP AND SYSTEM THEREOF

摘要

The block chain-based ballast water treatment result verification method by the BMWS (Ballast Watwer Management System) operating vessel according to an embodiment of the present invention, the BWMS operating vessel processes the ballast water at a first time, and the second Generating a first data block including first log data including the first processing result and a first hash value matching the first log data based on the first processing result processed at one point in time; Encrypting the first hash value according to a preset encryption method, processing the ballast water at a second time point, and including the second processing result based on the second processing result processed at the second time point generating a second data block including second log data, a second hash value matching the second log data, and the encrypted first hash value; and the first data block and the second data block. It may include the step of forming a block chain that
