Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a block chain-based marketing tag authenticity verification method includes the following steps:
s1, a seller node sends a marketing label to other nodes in a block chain network;
s2, other nodes acquire all clients transacted with the seller and all clients contained in the received marketing labels, and respectively record the clients as a set A and a set B;
and S3, judging whether the set A contains the set B, if so, verifying the marketing label to be real, otherwise, verifying the marketing label to be fake, and storing the verification result in the block chain.
And S1, the seller node sends the marketing label to other nodes in the block chain network.
Each node in the blockchain network verifies the authenticity of the desensitized shared marketing tag.
And S2, acquiring all the clients transacted with the seller and all the clients contained in the received marketing labels by other nodes, and respectively recording the clients as a set A and a set B.
And other nodes acquire a customer blockchain address set A transacted with the selling label node according to the blockchain address of the selling label node.
And S3, judging whether the set A contains the set B, if so, verifying the marketing label to be real, otherwise, verifying the marketing label to be fake, and storing the verification result in the block chain.
If set B is a subset of set A, then the shared marketing label is authentic, otherwise the shared marketing label is counterfeit.
To avoid the inclusion of personal privacy in the marketing tags, the present invention employs shared marketing tag desensitization. Specifically, the seller node desensitizes the shared marketing label before sending the marketing label, and obtains a desensitized shared marketing label.
In order to avoid the possible problem of marketing label data leakage in the verification process, the invention adopts marketing label encryption and trusted environment authentication. As shown in fig. 2, a block chain-based marketing tag authenticity verification method includes the following steps:
s0. the seller node encrypts the marketing label;
s1, a seller node sends an encrypted marketing label to other nodes in a block chain network, and directly sends a corresponding key to a trusted environment passing through a trusted environment authentication node;
s2, acquiring all clients transacted with the seller outside a trusted environment through a node authenticated by the trusted environment, marking as a set A, and reading the set A into the trusted environment; decrypting the encrypted marketing label in the trusted environment, and acquiring all clients contained in the decrypted marketing label, and recording as a set B;
and S3, judging whether the set A contains the set B in the trusted environment, if so, verifying the marketing label to be real, otherwise, verifying the marketing label to be fake, and storing the verification result in the block chain.
Step S0. the seller node encrypts the marketing label.
The marketing label encryption algorithm can be a symmetric encryption algorithm such as a 3DES algorithm and an AES algorithm, and can also be an asymmetric encryption algorithm such as RSA and Elliptic Curve Cryptography (ECC).
The unique identification of the marketing label is generated using, for example, a SHA-2 hash encryption algorithm, a SHA-3 hash encryption algorithm, a RIPEMD-160 hash encryption algorithm, or the like.
And S1, the seller node sends the encrypted marketing label to other nodes in the block chain network and directly sends the corresponding key to a trusted environment passing through the trusted environment authentication node.
The trusted context may be an execution context created by sgx (software Guard extensions) or the like, and the trusted context is created before an operation is performed in the trusted context, and is revoked after the operation is completed in the trusted context. The trusted environment authentication is realized by means of signature.
S2, acquiring all clients transacted with the seller outside a trusted environment through a node authenticated by the trusted environment, marking as a set A, and reading the set A into the trusted environment; and decrypting the encrypted marketing label in the trusted environment, and acquiring all the clients contained in the decrypted marketing label, which is marked as a set B.
The other nodes need to read the encrypted desensitized shared marketing tag into the trusted environment before decrypting the encrypted desensitized shared marketing tag in the trusted environment.
And S3, judging whether the set A contains the set B in the trusted environment, if so, verifying the marketing label to be real, otherwise, verifying the marketing label to be fake, and storing the verification result in the block chain.
The trusted environment outputs the verification result and a client blockchain address set B contained in the sold tag, and stores the client blockchain address set B, the unique identifier and the desensitization shared marketing tag ciphertext together with the blockchain address of the sold tag node in the local environment.
The information content of the shared tag stored locally is shown in table 1:
Figure BDA0002041804790000061
TABLE 1
To protect against single point of failure or malicious tampering, the present invention deploys an intelligent contract in the blockchain that is responsible for recording the authenticity of desensitized shared marketing tags uploaded by shared tag sellers to the blockchain network, and is applicable to both methods. The step of storing the verification result in the block chain comprises the following steps:
(1) and the seller nodes construct a special transaction, the special transaction is used for calling an intelligent contract to record the authenticity of the sold shared marketing label, and the outlet nodes add authenticity information of the marketing label to the special transaction.
The special transaction contains a unique identification. Before the node in the blockchain network executes the special transaction, the authenticity of the desensitization shared marketing label and a customer blockchain address set contained in the sold desensitization shared marketing label are locally acquired according to the unique identifier and the blockchain address of the node initiating the special transaction, and the information is added into the special transaction.
Specifically, the contents stored in the smart contract a are shown in table 2:
Figure BDA0002041804790000071
TABLE 2
(2) And the block outlet node in the block chain network executes the special transaction, packs the transaction into a block and sends the block into other nodes for consensus.
In the consensus process, other nodes can locally acquire self-verification label authenticity results from the nodes, then the results are compared with label authenticity information contained in the special transactions in the block, if the results are consistent, the other nodes acknowledge that the special transactions executed by the block nodes are valid, and if the results are invalid, the special transactions executed by the block nodes are invalid.
Specifically, when other nodes perform a consensus transaction, the authenticity of the desensitization shared marketing label and the client blockchain address set included in the sold desensitization shared marketing label are locally acquired according to the unique identifier and the blockchain address of the node initiating the special transaction. And if the locally stored information is consistent with the information stored in the special transaction, the special transaction processed by the block node is admitted, otherwise, the special transaction processed by the block node is refused to be admitted.
In the conventional transaction consensus process, if one wants to verify one conventional transaction (denoted as transaction a) in the block, it needs to go to the block chain to find the related information of both parties in transaction a. Unlike the consensus process of handling traditional transactions, the present invention seeks to find authenticity information in a particular transaction outside of the blockchain when verifying authenticity information in a particular transaction (since the authenticity information in a particular transaction is not linked but stored outside of the blockchain before other nodes verify the particular transaction).
The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
