Embodiment Construction
[0029] In order for those skilled in the art to better understand the technical solutions in the embodiments of this specification, the technical solutions in the embodiments of this specification will be described in detail below in conjunction with the drawings in the embodiments of this specification. Obviously, the described implementation Examples are only some of the embodiments in this specification, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this specification shall fall within the scope of the disclosure.
[0030] Big data analysis is mainly used to analyze massive data according to the needs of customers. In the process of big data analysis, there may be problems such as inaccurate customer data and data processing errors. For example, customer data is missing or redundant, customer data has wrong data, or the data analysis process is performed incorrectly, etc.
[0031] The reason for these p...

The invention discloses a data storage method, device and system based on a trusted account book database. The method comprises the following steps: a big data client sends a target data set to a bigdata server and sends a data record containing a hash value set corresponding to the target data set to a trusted storage end; under a specified condition, the big data server preprocesses the targetdata set, takes the preprocessed target data set as a to-be-analyzed data set, and sends a corresponding preprocessing process record to the trusted storage terminal; the preprocessing comprises the following steps: sequentially executing data extraction, data cleaning and data conversion; the big data server side executes big data analysis on the to-be-analyzed data set and sends a correspondinganalysis process record to the trusted storage side; the trusted storage end maintains a trusted account book database; and the trusted storage end writes each record into the trusted account book database in sequence according to the sequence of receiving each record.
Description
technical field [0001] The embodiments of this specification relate to the field of data storage, and in particular to a data storage method, device and system based on a trusted ledger database. Background technique [0002] Big data analysis is mainly used to analyze massive data according to the needs of customers. In the process of big data analysis, there may be problems such as inaccurate customer data and data processing errors. For example, customer data is missing or redundant, customer data has wrong data, or the data analysis process is performed incorrectly, etc. [0003] The reason for these problems may be that the customer made an error, or the big data analysis service provider made an error, or it may be an error in the data transmission process, etc. [0004] However, since big data analysis is centralized, it is difficult for customers and big data analysis service providers to trust each other at the technical level, making it difficult to determine the...
