Mobile edge computing (MEC) can effectively support various high reliability and low delay maritime applications, but security risks in computing tasks offloading exist. We describe a maritime network (MN) model based on MEC, and analyze the risk of data privacy leakage of maritime mobile terminal (MMT) during the offloading tasks. For abnormal maritime monitoring data (MMD), a data cleaning algorithm of sample density-based local outlier factor (SD-LOF) is proposed. It can effectively save the cost of data privacy protection (DPP) and improve the quality of MEC service. For data privacy leakage of MMT, an attribute sensitivity-based differential privacy (AS-DP) algorithm is proposed to balance security and availability of data and improve the differential privacy protection utility. Experimental results have verified the validity of the proposed two algorithms.
