Embodiment Construction

[0035] Main design idea of ​​the present invention is:

[0036] The risk-prone factors in the process of sharing and distributing marine big data mainly include the value of the data itself and the potential threats in the transmission process. The risks arising from the sharing and distribution of marine big data are controllable. We need to start modeling from the perspective of data value, first of all, from the spatiotemporal value attributes of marine big data (data from different spaces at the same time is valuable), and the associated value attributes (Remote sensing data, meteorological data, hydrological data, etc. are of related value), independent value attributes (the value increases after data collection and calculation), open and shared attributes, and the minimum openness required by scientific research cooperation requirements for data requirements, etc. Angle, design risk control model. In addition, comprehensive consideration should be given to the way of sh...

Abstract

The invention discloses a marine big data sharing and distribution risk control model and method, and the method comprises the following steps: employing an improved analytic hierarchy process to analyze the value security of marine data to be shared and distributed, and carrying out the quantification of the value features of the marine data; enabling the sensitive data perceiving and filtering framework to process and select the ocean data to be shared and distributed, processing the quantized value features and calculating the sensitive similarity of the data; in combination with a marine big data sensitive information base, querying a corresponding sensitive level, and respectively performing data desensitization or data blocking or permitted data output processing on the data to be shared and distributed according to the sensitive similarity and the relationship between the sensitive level and a set threshold value in the sensitive data filtering strategy library; In the data transmission process, the risk of data sharing and distribution is controlled within an acceptable range by improving an intrusion detection system.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a risk control model and method for sharing and distributing marine big data. Background technique [0002] With the development and progress of marine technology, data sources are abundant and stored in different marine units. In order to meet the requirements of information openness and sharing, all units need to share and distribute data. Big risks happen. First of all, there is a large amount of marine data, various data formats, complex calculation process, and it is difficult to ensure the integrity of the data; secondly, there is no mature set of risk control models and risk control methods for the sharing and distribution of marine big data. [0003] Driven by the global trend of information openness and sharing, the sharing and distribution of marine big data is inevitable from the perspectives of cross-unit scientific research cooperation, social co...
