Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the present invention is a block chain-based identity card information query solidification and evidence collection method, including the following steps.

[0034] (1) The ID card information inquiry solid certificate, specifically includes the following steps.

[0035] (1.1) Based on the alliance blockchain network, the elliptic curve algorithm is used to generate a pair of query node and query center node

[0036] public and private keys ( P, S ), as the unique identity on the chain; the steps are as follows:

[0037] (1.1.1) The node selects an elliptic curve E( x, y ), and take E( x, y ) on any base point G( x', y' ), calculate G( x', y' ) order n ;

[0038] (1.1.2) select integer k ( k base point G (x', y' ) order) is used as the private key of the node, and the public key of the node is calculated ac...

Abstract

The invention belongs to the technical field of identity information security, and specifically relates to a block chain-based ID card information query consolidation and evidence collection method. In the present invention, the query center and the querying parties are first constructed into an alliance block chain network, and an elliptic curve algorithm is used to generate a public key and a private key for the central node and each query node; then the query node encrypts the query request and hashes the query request On the chain, when the central node receives the query request, it returns the query result, encrypts the query record and uploads the query log to the chain, and completes the information query certificate; when the query node is inconsistent with the central node record, check whether there is a corresponding Query requests and query records, and complete query and evidence collection. The invention clarifies the data credibility of the ID card information query system, solves the problem of inconsistency in query records caused by the user's ID card information being cached by the query party, and has important application value in the traceability of the query track of the information system and the storage of business data. .

Description

technical field [0001] The invention belongs to the technical field of identity information security, and in particular relates to a district identity card information query consolidation and evidence collection method. Background technique [0002] When the public ID card query center provides ID card information query and verification services, there is a problem of data inconsistency between the query center and the query party. The usual way to solve this problem is to retrospectively verify the historical query records. However, the query record data is often stored in a single point system, which is easy to be destroyed or tampered with, thus affecting the credibility of the query records. In order to solve the security problem of query records, existing data protection schemes usually incrementally store log data according to timestamps to form log chains, and compress or recalculate the log chains to reduce storage space and recovery time overhead. One-way hashing i...
