Example Embodiment

[0028] Example 1:

[0029] figure 1 A schematic structural diagram of a data storage system provided by some embodiments of the present invention, the system includes: a server 101 and a first blockchain node 102;

[0030] The server 101 is configured to receive a certificate deposit request and obtain the electronic data carried by the certificate deposit request; based on a national secret algorithm, extract the characteristic value of the electronic data, and send the characteristic value to the first block chain node 102;

[0031] The first blockchain node 102 is configured to receive and save the feature value.

[0032] In this embodiment of the present invention, after the server 101 receives the certificate deposit request, the electronic data carried in the certificate deposit request may be acquired based on the received certificate deposit request. In order to prevent the electronic data from being too large and occupying the memory in the node, in the embodiment ...

Example Embodiment

[0035] Example 2:

[0036] In order to accurately store the electronic data, on the basis of the above embodiments, in this embodiment of the present invention, the server 101 is further configured to extract the electronic signature carried in the electronic data, according to the pre-stored public key pair The electronic signature is verified, and if the verification of the electronic signature is passed, the characteristic value of the electronic data is obtained based on the national secret algorithm.

[0037] Since the electronic data is not necessarily true, in order to ensure the reliability of the stored electronic data, the reliability can be ensured by verifying the electronic signature carried in the electronic data. Specifically, when the server 101 receives the storage certificate carrying the electronic data After the request, the electronic signature carried in the electronic data is obtained, and the obtained electronic signature is verified according to the pr...

[0041] Example 3:

[0042] In order to accurately realize the storage of electronic data, on the basis of the above embodiments, in this embodiment of the present invention, the server 101 is further configured to obtain the electronic data category carried in the certificate deposit request, and store the The electronic data category and the characteristic value are sent to the first blockchain node 102;

[0043] The first blockchain node 102 is configured to receive and save the electronic data category and the feature value.

[0044] In order to facilitate the storage of electronic data, in this embodiment of the present invention, the certificate storage request also carries the electronic data category. After the server 101 receives the certificate storage request, it will obtain the electronic data category carried in the certificate storage request, and store the electronic data category in the certificate storage request. The electronic data category and feature value...

Abstract

The invention discloses a data storage system, method and equipment and a medium, which are used for solving the problems of tedious flow, low efficiency and high cost during data storage in the prior art. According to the embodiment of the invention, only the evidence storage request needs to be sent to the server during data storage, so that the process is simple, and after the server receives the evidence storage request, the server obtains the characteristic value of the electronic data and sends the characteristic value to the first block chain node, and the first block chain node stores the characteristic value; and automatic storage is realized, so that the labor cost during storage is reduced, and the storage efficiency is improved.

Description

technical field [0001] The present invention relates to the field of blockchain technology, and in particular, to a data storage system, method, device and medium. Background technique [0002] With the progress of society, the development of electronic data has become particularly important. Electronic data is the product of modern high technology. Electronic data has the characteristics of easy creation, easy storage, easy transmission and high utilization rate. It is reliable and proven. evidence. The electronic data includes images or advertising slogans. Since the electronic data is the intellectual activity of the user, in order to prevent the risk of infringement of the electronic data, the electronic data needs to be saved, and when the electronic data is saved, there is a risk of easy tampering. [0003] In the prior art, when electronic data storage is carried out, it mainly relies on the notary office, and when electronic data is stored, the data should be bette...
