Problems solved by technology
[0003] When the existing blockchain system transmits user information to the database, the entire text is encrypted and placed in a table. Once the data in this table is leaked, the contents of the table are completely leaked, and the security is not good. High; in addition, the overall encryption method can also be cracked through repeated mechanical decryption, and it is further determined that there is a completed data in a separate database, which is very dangerous for the existing data, so the present invention introduces a block chain The data authorization method is used to solve the above problems

Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] see figure 1 , a blockchain data authorization method, comprising the following steps:
[0025] step one:
[0026] Split the data that needs to be saved into three parts, and integrate the fields according to the equal division rules; the third part can divide the data into multiple parts;
[0027] Step two:
[0028] Separately encrypt the data divided into three parts, the encryption method can be encrypted by MD5 encryption method, and the encrypte...

The invention relates to the technical field of block chain data security, and discloses a block chain data authorization method. The method comprises the following steps: 1, data needing to be stored are divided into three parts, field integration is carried out according to an equal division rule, and the third part can be divided into multiple pieces of data; 2, the data split into the three parts are independently encrypted, an MD5 encryption mode can be adopted for encryption, and the encrypted data are placed into a table 1, a table 2 and a table 3 in a database; and 3, when data in the table needs to be called, querying is carried out according to the original field. According to the data authorization method of the block chain, different fields in different data tables in different folders are independently encrypted and then are stored in tables after encryption, so that data extracted from each table is confidential data, and data in multiple tables cannot be extracted and restored; therefore, the safety can be further improved.
Description
technical field [0001] The invention relates to the technical field of blockchain data security, in particular to a blockchain data authorization method. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, the block Chain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects [0003] When the existing blockchain system transmits user information to the database, the entire text is encrypted and placed in a table. Once the data in this table is leaked, the contents of the table are completely leaked, and the security is not good. High; in addition, the overall encryption method can also be cracked through repe...
