Embodiment Construction

[0026] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the blockchain-based file storage method provided by the embodiment of the present invention includes the following steps:

[0028] S101. Create a block header and add the block header to a file.

[0029] S102. Encrypt the file using an encryption algorithm.

[0030] Wherein, the encryption algorithm may be a symmetric encryption algorithm or an asymmetric encryption algorithm.

[0031] S103, storing the file in each blockchain node.

[0032] Optionally, as in figure 2 As shown, creating a block header and adding the block header to the file includes:

[0033] Using a convolutional neural network-based text classification model to classify the files, combining files of the same type to generate multiple data blocks;

[0034] Add the block header to each data block respectively, wherein the block he...

Abstract

The invention discloses a file storage method and system based on a block chain and relates to the technical field of data storage, The method comprises the steps of creating a block head and adding the block head to a file; The file is encrypted by using the encryption algorithm, and the file is stored in each block chain node, so that the leakage of private data can be effectively prevented, thesecurity of file storage is improved, and the defects that the privacy and important data leakage cannot be effectively prevented and the file storage security is relatively low in the prior art aresolved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a block chain-based file storage method and system. Background technique [0002] With the explosive growth of the network information industry, the security of various information carriers such as databases and electronic documents has become an increasingly prominent issue. The commercial secrets of various countries, military forces, institutions and enterprises are facing various security threats. The means to prevent information leakage include firewalls, VPNs, intrusion detection systems, intranet monitoring, etc., which can protect the security of their sensitive information to a certain extent. However, traditional means have been difficult to cope with the current threats, and the existing security prevention means have obvious lag in attack methods such as Oday loopholes and social engineering. In this case, traditional defense methods can no longer ensure the sec...
