Embodiment Construction

[0024] Embodiments of the technical solution of the present invention will be described in detail below. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the usual meanings understood by those skilled in the art to which the present invention belongs.

[0026] In one embodiment, the present invention first proposes a secondary hash-based associated certificate storage method, including steps:

[0027] Count transaction data on multiple transaction nodes, collect trader's biometrics during transactions, and establish associations between transaction data and biometric data;

[0028] Perform a hash operation on the transaction data to obtain the first abstract, perform a hash ope...

Abstract

The invention provides an associated evidence storage method and system based on double hashing. When the method and the system are used, a first abstract is used as an irreversible hash result of transaction data, a second abstract is used as an irreversible hash result of biological characteristic data, and when data verification needs to be performed on the transaction data and the biological characteristic data in the later period, whether the transaction data and the biological characteristic data are tampered can be known only by performing hash operation on the transaction data and thebiological characteristic data again to compare whether the transaction data and the biological characteristic data are equal to the first abstract / second abstract; the first abstract and the second abstract are spliced in series, and then hash operation, namely secondary hash is carried out; and when the association between the transaction data and the biological characteristic data needs to be verified in the later period, whether the first abstract and the second abstract in the splicing string are tampered or not can be known only through carrying out harsh operation on the spliced stringand comparing with a third abstract, and if the first abstract and the second abstract in the splicing string are not tampered, it is indicated that the two pieces of data in the group are original and immobile and the matching is not tampered.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a secondary hash-based associated certificate storage method and system. Background technique [0002] Blockchain can be used to automate tasks and processes that are not limited to the field of cryptocurrencies, such solutions will be able to use the characteristics of blockchain to better encrypt transactions. There is a serious centralization phenomenon in all issues in the market. Whether it is credit cards, airline flights, shopping malls, or online shopping malls in the telecommunications industry, they are all promoted by their respective companies or platforms. At present, there are some blockchain digital transaction processing technologies based on facial recognition, but there is no effective solution to ensure the matching correlation between transaction data and facial data. Contents of the invention [0003] Aiming at the defects in the prior art, the presen...
