Problems solved by technology

[0003] However, there are the following problems in the existing technology: the information recorded in the existing blockchain can prevent the stored transaction data from being tampered with through the blockchain technology, but it cannot guarantee that the information is legal, which increases the security of the block information. insecurity

Embodiment 1

[0029] This embodiment provides a blockchain-based information authorization method, which includes:

[0030] Step A1. Obtain the application form information set, and obtain the application form information that meets the preset authorization conditions from the application form information set;

[0031] Step A2. Generate the digital fingerprint of the main chain according to the application form information that meets the preset authorization conditions; generate the main chain block header according to the hash value of the parent block of the main chain, the digital fingerprint of the main chain and the time stamp of the main chain; The application form information and the main chain block header generate the main chain block and broadcast it to the network;

[0032] Specifically, generating the digital fingerprint of the main chain according to the application form information that meets the preset authorization conditions specifically includes:

[0033] Step 101, perfor...

Embodiment 2

[0072] This embodiment provides a blockchain-based information authorization method, which includes a main chain and side chains; for example, a stock exchange has at least one main chain and multiple side chains, and the main chain mainly records all entry application forms The application form information in the information collection, and issue authorization certificates to all application form information; the side chain mainly records the application form information of all successful transactions of each stock and has authorization certificates. Such as figure 1 As shown, this method specifically includes:

[0073] Step 101, judging whether the conditions for generating the main chain block are met, if so, execute step 102, otherwise continue to execute step 101;

[0074] Specifically, step 101 may be to judge whether the application form information in the application form information set is greater than the preset number, if yes, execute step 102, otherwise continue t...

Embodiment 3

[0131] This embodiment provides a blockchain-based information authorization method, which includes a main chain and a side chain; for example, the Education Bureau has at least one main chain, and each university has at least one The student information of the degree certificate is issued, and the authorization certificate is issued to all the student information that is allowed to issue the degree certificate; the side chain is mainly used to record the student information of a certain university awarded the degree certificate by the Education Bureau. Such as figure 2 As shown, this method specifically includes:

[0132] Step 201, judging whether the conditions for generating the main chain block are met, if so, execute step 202, otherwise continue to execute step 201;

[0133] Specifically, step 201 may be to judge whether the application form information in the application form information set is greater than the preset number, if yes, execute step 202, otherwise continu...

Abstract

The invention relates to the financial field, particularly to a block-chain-based information authorization method and apparatus. The method comprises: an application form information set is obtained, a main chain block is generated based on information of an application form meeting a preset authorization condition, a main chain father block hash value, and a main chain time stamp, and the main chain block is broadcasted to a network; hash operation is carried out on a main chain block head of a newly added main chain block to generate authorization data, an authorization evidence is bound with application form information in the newly added main chain block to generate authorization information; according the authorization information including a preset side chain identifier, a side chain digital fingerprint is generated; according a side chain father block hash value, the side chain digital fingerprint, and a time stamp, a side chain block head is generated; and on the basis of the authorization information and the side chain block head, a side chain block is generated and the generated side chain block is broadcasted to the network. According to the invention, the main chain and the side chain are built by employing a block chain technique; and the information stored by the side chain is obtained by authorization of the main chain, so that security and validity of information can be guaranteed.

Description

technical field [0001] The present invention relates to the financial field, in particular to a block chain-based information authorization method and device. Background technique [0002] With the rise of digital currency, blockchain has emerged as a distributed ledger technology. Blockchain is an Internet database technology. This database contains information such as all past transaction data and related data. Centralization, openness and transparency, that is, the information recorded on the blockchain is distributed and stored and transparently checkable, and the information is guaranteed not to be tampered with in a cryptographic protocol. [0003] However, there are the following problems in the existing technology: the information recorded in the existing blockchain can prevent the stored transaction data from being tampered with through the blockchain technology, but it cannot guarantee that the information is legal, which increases the security of the block informa...
