Problems solved by technology
However, few existing technologies focus on the big data generated by users or to be stored and processed, as well as the characteristics of the attributes of each storage node, such as storage medium characteristics (magnetic, semiconductor, phase change) and physical operating parameters of different storage nodes (such as the number of erasures, the probability of failure such as damage) and security features (such as the probability of being attacked or destroyed), the hidden dangers brought to the safe storage of big data; at the same time, in the existing technology, by using big data Perform local and cloud distributed storage. However, hackers or criminals can obtain big data information by decrypting (some user's big data does not even have an encryption link, correspondingly, directly) by stealing part of the data in the local or cloud , resulting in the disclosure of user privacy or personal information

The invention relates to a big data-based storage node space capacity and safety evaluation method, which comprises the steps of determining an available cloud node, and obtaining a storage medium type of a cloud node for storing big data; based on different node storage medium types, obtaining an upper limit value TT of read-write erasure use times and an available storage space through a lookuptable, and obtaining read-write erasure times ERW, a safety factor SE and a fault abnormality probability FA of different blocks of the storage medium of each node; evaluating the safety performance of each node; sorting according to a descending order based on the calculated numerical value of the safety performance of the node k; sending the available storage spaces corresponding to the sorted nodes to a secure storage controller; and when the method finally determines to use the block j in the node k, adding 1 to the read-write erasure frequency ERW of the block j. According to the method,the node space capacity and the safety of each storage node can be evaluated based on the attribute of each storage node for the big data generated by a user or to be stored and processed, and the accuracy of evaluating the node space capacity and the safety of each storage node is improved, so that the safety storage of the big data is realized.
Description
technical field [0001] The present invention relates to the field of electrical data processing, and more specifically, to a method and system for secure storage control based on big data. Background technique [0002] With the development of computer technology and the advancement of network technology, great changes have taken place in human work and life. Now people are contacting, reading, storing, and processing information every day, such as social interaction through mobile terminals, obtaining news, Query knowledge elements, shopping, entertainment, etc., which multiplies the amount of data created. The resulting mass of data is called big data. While big data brings convenience to users, it also brings some security risks. For example, criminals will get the user's private information after processing and analyzing the big data of the user. For example, the e-commerce website will know the user's shopping habits, the social software provider will know the user's s...
