Problems solved by technology

[0003] The traditional item traceability technology faces five types of problems: (1) the single point of failure in the centralized traceability information database; (2) the problem of forged data or data tampering in the traceability information database; (3) the existence of traceability information The problem of being denied by the transaction party; (4) The problem of the inconsistency between the physical label information of the item and the digital identification in the traceability information database; (5) The problem of weak detection ability for physical label copy attacks
[0005] However, there is no good solution for the synchronization of the physical ID of the anti-counterfeit label of the item and the digital identity ID of the item, especially when the physical tag of the item is copied, and then the digital traceability information of the item is attacked, there is no effective detection method

Embodiment 1

[0079] A blockchain tracing method for anti-copy attack in this embodiment includes the following contents:

[0080] (1) Double binding of blockchain-based digital IDs and anti-copying physical labels to items, as well as corresponding label coding and management;

[0081] That is, the item label contains secondary physical tags: a first physical tag and a second physical tag, the first physical tag and the second physical tag are used for the traceability and anti-counterfeiting of a single item and a group of items, respectively; The anti-duplication function of the unclonable function (PUF), for example, by configuring a corresponding anti-duplication circuit in the chip of the second physical tag;

[0082] (2) Based on the secondary physical label and blockchain system, open and transparent tracking and real-time inquiry of goods are carried out, as follows;

[0083] (2.1) Set up event listeners, set event listeners for the item release contract and the item transfer cont...

Embodiment 2

[0092] The blockchain tracing system for anti-copy attack in this embodiment involves the following contents:

[0093] (A), an item traceability smart contract, which is used to process on-chain storage and query requests for item status information;

[0094] The item traceability smart contract includes the user registration contract module, the item release contract module, the item circulation contract module and the item query contract module;

[0095] (B), a physical tag reading and writing device, used to read and rewrite the internal information of the secondary physical tag, and communicate with the item traceability smart contract to respond to the item transfer request and complete the update of the item status information;

[0096] (C) The client is used to process the user's query and traceability request, display the production information and circulation information of the item, and detect the copy attack behavior of the physical label.

Embodiment 3

[0098] This embodiment takes the sales of a certain brand of bottled wine as an example, and specifically describes the application of the technical solution of the present invention in the sales process of bottled wine. From this embodiment, it can be seen that the technical solution of the present invention can effectively resist the multi-link circulation process of bottled wine. Facing counterfeiting and counterfeiting.

[0099] The blockchain traceability system for anti-copying attacks in this embodiment includes an item traceability smart contract designed based on a blockchain application architecture, a physical tag reading and writing device, and a client application program.

[0100] In this embodiment, the blockchain platform constructed by Hyperledger Fabric 2.0 is used as the infrastructure of the traceability system. Bottled wine producer P and n-level distributor D = {D 1 ,…,D i ,…D n } Jointly join the bottled wine sales alliance created by the producer P, ...

Abstract

The invention discloses an anti-copy attack block chain tracing method and system, and the method comprises the steps: carrying out the dual binding of a digital ID based on a block chain and an anti-copy physical tag, and carrying out the corresponding tag coding and management; based on a secondary physical label and a block chain system, public and transparent article circulation tracking and real-time query are carried out on the article; and packaging the second-level physical label which is consistent with and coincides with the article package, and tracing the corresponding article information. The method can resist mass copy attacks of the physical tags, and can accurately position the occurrence stage of the copy attacks at the same time; the overall cost of label packaging is low.

Description

technical field [0001] The invention relates to a blockchain tracing technology, in particular to a blockchain tracing method and system against copying attacks. Background technique [0002] The sales process of an item from a manufacturer to a consumer usually goes through multiple links, generating a large amount of circulation information. How to ensure the authenticity of the item circulation information and be able to trace it efficiently has always been the research direction of those skilled in the art. A common concern from producers to consumers. [0003] The traditional item traceability technology faces five types of problems: (1) the single-point failure problem in the centralized traceability information database; (2) the problem of forged data or data tampering in the traceability information database; (3) the existence of traceability information The problem of being denied by the transaction party; (4) The problem that the physical label information of the ...
