Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
The terms "first" and "second" in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the term "comprises" and any variations thereof, which are intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
In the embodiments of the present invention, the "plurality" may mean at least two, for example, two, three, or more, and the embodiments of the present application are not limited.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.
In the prior art, in a traditional consensus process of a federation chain, a client must transmit transaction data to an endorsement node in a plaintext form, so that the endorsement node performs operations such as intelligent contract operation, data calculation, verification, signature verification and the like, then the endorsement node returns a transaction result and a signature to the client, the client sends the transaction result and the signature to the consensus node, the consensus node receives the transaction result and the signature sent by the client and forwards the transaction result and the signature to a message queue for sequencing, after the message queue is sequenced, the consensus node receives the sequenced transaction accounting data, divides the data into blocks, and distributes the blocks to the endorsement node and the accounting node in a network, so that the consensus node receives the accounting data from the consensus node and other accounting nodes, and stores the complete accounting data of the federation chain.
As mentioned above, all nodes in the federation chain can acquire clear data on the federation chain, for example, based on marketing service of the federation chain, functional nodes included in the federation chain in the application scenario include a provider node, a buyer node and a marketer node, but since in a specific practical application, there is more than one person involved in the buyer node and the marketer node, if all transaction data is written in the federation chain in the form of clear data, then all nodes in the chain can acquire the transaction data, which does not meet the requirement of privacy protection.
Therefore, in the prior art, a method is adopted to encrypt transaction data of an alliance chain to be linked by using a symmetric encryption algorithm, and then to link the encrypted transaction data, however, in the method, when an encryption party encrypting the transaction data wants to share plaintext data corresponding to the transaction data to a node with permission to view, a symmetric key needs to be distributed to the other party, and in practical application, in the distribution process of the key, the key is easy to be stolen, so that the security of the encrypted transaction data is low.
In view of this, an embodiment of the present invention provides a method for processing transaction data based on a federation chain, where the method may perform hash calculation on transaction private data to be linked up to obtain a hash value, and then link up the hash value of the transaction private data to protect security of the transaction private data, and further, when it is desired to share plaintext data of the transaction private data to other nodes having permission to view, the plaintext data may be sent to the node through a transmission protocol, so as to achieve a purpose of protecting security of the transaction private data, and improve security of the transaction data.
After the design idea of the embodiment of the present invention is introduced, some simple descriptions are provided below for application scenarios applicable to the technical solution for determining a cloned vehicle in the embodiment of the present invention, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present invention and are not limited. In specific implementation, the technical scheme provided by the embodiment of the invention can be flexibly applied according to actual needs.
At present, in terms of marketing service processing based on a federation chain, please refer to fig. 1, which generally includes three functional nodes, where the marketing service participants of the functional nodes are marketer, buyer and provider respectively, and the functional nodes can publish transaction data corresponding to their associated transaction events in the marketing service, that is, the functional nodes can be referred to as publishing nodes, and for convenience of distinguishing description, they are referred to as marketer nodes, buyer nodes and provider nodes as shown in fig. 1.
In the application scenario, the specific process of the marketing service is as follows: firstly, the marketer node sends product information to the buyer node, communication is carried out between the marketer and the buyer (as shown in step 1 in fig. 1), thereby a transaction preliminary agreement, namely a transaction pre-order is achieved, the marketer can link the transaction pre-order information (as shown in step 2 in fig. 1), then the supplier node obtains the transaction pre-order (as shown in step 3 in fig. 1), the transaction pre-order is processed to generate a corresponding transaction contract, the transaction contract is linked (as shown in step 4 in fig. 1), secondly, the buyer node obtains the transaction contract and determines product amount data in the transaction contract, then the supplier node determines to deliver goods to the buyer according to the transaction contract and links determined delivery information, thereby the buyer node determines to determine payment information after receiving the determined delivery information and determining to receive the goods, then, after receiving the payment confirmation information, the provider node confirms the withdrawal amount data of the marketer (step 5 in fig. 1), and links the withdrawal amount data of the marketer, so that the marketer corresponding to the withdrawal amount information obtains the withdrawal amount data of the marketer (step 6 in fig. 1).
In the embodiment of the present invention, in the application scenario, the supplier node, the marketer node, and the buyer node may all issue transaction data in the federation chain, and in the application scenario, the issue transaction data of the supplier node, the marketer node, and the buyer node may be supported by a server corresponding to the supplier node, so that the federation chain operates better.
The technical scheme provided by the embodiment of the invention is described in the following with the accompanying drawings of the specification.
Referring to fig. 2, an embodiment of the present invention provides a method for processing transaction data based on a federation chain, where the method may be performed by a server in the foregoing application scenario, and in a specific implementation process, the server is, for example, a personal computer, a large-medium-sized computer, a computer cluster, or the like. The specific flow of the method is described below.
Step 201: first transaction privacy data in the marketing business are obtained, wherein the first transaction privacy data comprise identity information of a first marketing participant corresponding to a current publishing node and/or first marketing data, and the first marketing data are used for representing transaction events related to the first marketing participant in the marketing business.
In the embodiment of the invention, when transaction data in the marketing service is desired to be processed, first transaction privacy data in the marketing service can be obtained, that is, the first transaction privacy data represents data that is not desired to be viewed by other publishing nodes without permission in the marketing service, wherein the first transaction privacy data includes identity information of a first marketing participant corresponding to a current publishing node and/or first marketing data, and specifically, the first marketing data is used for representing a transaction event associated with the first marketing participant in the marketing service.
In a specific implementation process, the first marketing participant corresponding to the current publishing node may be any one of the suppliers, buyers and marketers in the foregoing application scenario, and it should be noted that, in an embodiment of the present invention, the publishing node is configured to publish the transaction data to any node in the federation chain, and further, when the corresponding first marketing participant of the current publishing node is a provider, the correspondingly determined first transaction privacy data includes at least one of supplier identity information, supplier bank account information, supplier contact information, buyer contact information, order product quantity data, order product unit price data, order product total amount data, marketer pull-up amount data, for example, the first transaction privacy data may be data including supplier identity information, order product information, and order product quantity data.
Further, if the corresponding first marketing participant of the current publishing node is the buyer, the correspondingly determined first transaction privacy data includes at least one of buyer identity information, buyer contact information, purchased product information and purchased product quantity data; and if the corresponding first marketing participant of the current publishing node is a marketer, the correspondingly determined first transaction privacy data comprises at least one of marketer identity information, marketer job number information, marketer bank account information and marketer proportion drawing data.
In the embodiment of the present invention, the method provided by the embodiment of the present invention is specifically described by taking the first marketing participant as an example of a supplier.
In a specific implementation process, please refer to fig. 3 for a process of obtaining first transaction privacy data in a marketing service:
step 301: sending a first request to a first other publishing node, wherein the first request carries a node identifier of a current publishing node, and the first request is used for requesting second transaction privacy data from the first other publishing node;
step 302: receiving second transaction privacy data sent by the first other publishing node through a predetermined data transmission protocol, wherein the second transaction privacy data comprise identity information of a second marketing participant and/or second marketing data corresponding to the first other publishing node, and the second marketing data are used for representing transaction events related to the second marketing participant in the marketing service;
step 303: first transaction privacy data is determined based on the second transaction privacy data.
As described above, when the first marketing participant is a supplier, the second marketing participant corresponding to the first other publishing node may be a buyer or a marketer, and assuming that the second marketing participant is a marketer as an example, the obtained first transaction privacy data may be the contract information in the application scenario and the identity information of the supplier corresponding to the contract information.
Further, the obtaining process of the first transaction privacy data is as follows: the method comprises the steps that a current publishing node, namely a publishing node corresponding to a supplier, sends a first request to a first other publishing node, namely a publishing node corresponding to a marketer, the publishing node corresponding to the marketer further obtains identification information of the publishing node corresponding to the supplier, the identification information is judged to be in a set of preset identifications, if the node corresponding to the supplier is determined to belong to the set of the preset identifications, second transaction privacy data are sent to the publishing node corresponding to the supplier through a preset transmission protocol (such as Gossip protocol), then the first transaction privacy data are determined according to the second transaction privacy data, namely the obtained second transaction privacy data are stored in the local, and the transaction data are synchronized among nodes with authority through the preset transmission protocol, so that the first other publishing node in a federation chain is prevented from obtaining the second transaction privacy data under the condition of no authority, the safe transmission of the second transaction privacy data is ensured, and the safety of the second transaction privacy data is improved.
For example, if the first marketing participant corresponding to the current publishing node is the provider a, the identification information is a, the second marketing participant corresponding to the first other publishing node is the marketer C, and the predetermined identification set is "a, b, and m", the first other publishing node may determine that the identification information a of the current publishing node is in the predetermined identification set, and send the second transaction privacy data to the first marketing participant provider a corresponding to the current publishing node through the predetermined transmission protocol.
In a specific implementation process, after the second transaction privacy data is obtained, the order demand information of the second marketing participant corresponding to the first other publishing node can be determined according to the second marketing data in the second transaction privacy data, the order demand information comprises product information and demand party information, and then the identity information of a first marketing participant of a current publishing node, the identity information of a second marketing participant corresponding to a first other publishing node and the order demand information are processed.
Continuing with the previous example, after the first marketing participant supplier a obtains the second transaction privacy data, order requirement information determined by the marketer C, such as that the buyer H reserves the M60 pieces of products, the buyer H reserves the D40 pieces of products, and the buyer H reserves the F70 pieces of products, may be determined, and then the order requirement information is processed with identity information, contact information (such as address, contact information, and the like) of the supplier a, the marketer C, and the buyer H, and bank account information, so as to determine the first transaction privacy data.
Step 202: and performing first hash processing on the first transaction privacy data to obtain a first hash value corresponding to the first transaction privacy data.
In the embodiment of the present invention, after the first transaction privacy data is obtained, a first Hash process may be performed on the transaction privacy data, so as to obtain a first Hash value corresponding to the first transaction privacy data, specifically, the first transaction privacy data is processed by using a Hash Algorithm, which may use an MD5(Message Digest5) Algorithm, or may use SHA-1(Secure Hash Algorithm-1), and of course, may also use a secret SM3 Algorithm or another Algorithm, which is not limited in the embodiment of the present invention.
Step 203: processing the first hash value and the node identifier of the current release node to obtain first uplink transaction data;
step 204: and performing uplink processing on the first uplink transaction data so as to distribute the first uplink transaction data to the alliance chain.
In the embodiment of the present invention, after the first hash value is obtained, the first hash value and the node identifier of the current publishing node may be processed, so as to obtain the first uplink transaction data, then the first uplink transaction data is uplink processed, and the first uplink transaction data is published to the alliance chain, that is, a first other publishing node that may obtain the first hash value determines the first uplink transaction data as data that is desired to be obtained through the node identifier of the current publishing node in the first uplink transaction data, and then receives the first transaction privacy data sent through the transmission protocol in a local obtaining manner, so as to ensure smooth transaction, and improve the security of the transaction data.
Therefore, by the above method, in the embodiment of the present invention, when desiring to process uplink transaction data, first transaction privacy data to be uplink-linked may be determined, that is, transaction data that is to be processed and is not intended to be viewed by other publishing nodes without permission is determined, then the first transaction privacy data is processed by using a hash algorithm, so as to obtain a first hash value corresponding to the first transaction privacy data, then the first hash value and identification information of a node corresponding to a current publishing node that obtains the first transaction privacy data are processed, so as to obtain the first uplink transaction data, and then the first uplink transaction data is uplink-linked, so that other publishing nodes that desire to view the first transaction privacy data and have permission to view may determine the corresponding hash value by the identification information corresponding to the first transaction privacy data, therefore, the first transaction privacy data can be obtained in a local transmission mode, and the publishing node without permission to view cannot obtain the first transaction privacy data information, so that the security of the transaction data can be improved, further, the first uplink transaction data and the transaction data uplink which can not be subjected to hash processing can better ensure that the marketing service based on the alliance chain operates smoothly, further, the privacy of the transaction privacy data is protected through the irreversibility of the first hash value per se in the mode of the first uplink transaction data uplink comprising the first hash value, the data volume on the alliance chain is reduced, the cost of operating the alliance chain is reduced, and the user experience is improved.
In a possible implementation manner, before determining the first transaction privacy data according to the second transaction privacy data, the second transaction privacy data may be further checked to determine the validity of the second transaction privacy data, specifically, the third hash processing may be performed on the second transaction privacy data to obtain a hash value to be checked corresponding to the second marketing service, and then second uplink transaction data corresponding to the first other publishing node is obtained from the federation chain, where the second uplink transaction data is data obtained by processing the second hash value and the node identifier of the first other publishing node, the second hash value is a hash value obtained by performing second hash processing on the second transaction privacy data by the first other publishing node, and then the hash value to be checked is compared with the second hash value included in the second uplink transaction data, if the hash value to be verified is the same as the second hash value, the received second transaction privacy data is determined to be valid, so that the authenticity and validity of the received second transaction privacy data can be more accurately determined, and the accuracy of obtaining the transaction data is improved.
In a possible implementation manner, the current publishing node may further obtain a second request sent by a second other publishing node, where the second request carries a node identifier of the second other publishing node, and the second request is used to request the current publishing node for the first transaction privacy data, and then determine whether the node identifier of the second other publishing node belongs to a predetermined identifier set, where the predetermined identifier set is used to characterize that the authority to obtain the first transaction privacy data, and if so, send the first transaction privacy data to the first other publishing node, in such a way, it may be ensured that the authority-possessed second other publishing node may obtain the first transaction privacy data, and other non-authority second other publishing nodes may only know that the authority-possessed data is uploaded but cannot obtain the first transaction privacy data, further, the current publishing node may also publish the data that may not be hashed into the federation chain, for example, assuming that the first marketing participant corresponding to the current publishing node is a marketer, the marketer can publish the product information to the alliance chain, so that buyers of the marketing participants corresponding to other publishing nodes can directly acquire the transaction data of the product information from the alliance chain, thereby ensuring the effective operation of marketing services, improving the security of the transaction data, and improving the experience of users.
Based on the same inventive concept, an embodiment of the present invention provides a federation chain-based transaction data processing apparatus, which is capable of implementing a function corresponding to the above federation chain-based transaction data processing method. The federation chain-based transaction data processing apparatus may be a hardware structure, a software module, or a hardware structure plus a software module. The transaction data processing device based on the alliance chain can be realized by a chip system, and the chip system can be formed by a chip and can also comprise the chip and other discrete devices.
