Description

Collaborative operation method based on electronic commerce and distributed resale platform thereof

Technical Field

The invention belongs to the technical field of Internet, and particularly relates to a collaborative operation method based on electronic commerce and a distributed resale platform thereof.

Background

With the development of internet information technology, the intense market competition makes enterprise manufacturers no longer limited to building traditional market circulation channels, but instead turns to focusing on the building of electronic commerce channels supported by internet information technology.

Electronic commerce is essentially a business activity using information network technology as a means and using commodity exchange as a center. It can be understood that under the open network environment of the internet, based on the application mode of the browser/server, the buyer and the seller do not perform various business activities, and a business mode and a business method for realizing online shopping of consumers, online transaction and online electronic payment among merchants, various business activities, transaction activities, financial activities and related comprehensive service activities are realized.

Common 7-class e-commerce modes are divided into: enterprise-to-enterprise e-commerce (i.e., B2B); e-commerce (i.e., B2C) of businesses and consumers; consumer-to-consumer electronic commerce (i.e., C2C); consumer and business e-commerce (i.e., C2B); e-commerce (i.e., B2G) for enterprises and administrative units; e-commerce (i.e., O2O) where online commerce merges with offline services; agents, merchants, and consumers (i.e., ABC); the method is mainly based on the large mode of enterprises and enterprises, enterprises and consumers (namely B2B, B2C, C C) 3.

The whole industry of electronic commerce is increasingly in the form of acceleration and hypodynamia along with the decline of the touch advantage of internet information. On the other hand, traditional market commerce does not have only such a single business feature from end to end, but rather exhibits an offline physical business "network feature" of multiple business feature collections. This also means that the single end-to-end business model currently presented by the online e-commerce industry is not an all-round feature of the e-commerce architecture. Meanwhile, in the conventional electronic commerce, the commodity information is not interconnected along with the high efficiency of the internet information, but is more layered.

Therefore, in the face of the acceleration bottleneck of the whole electronic commerce industry, how to construct an electronic commerce network with the information traceability; how to connect the consumer demand of consumer object with the production decision of enterprise, realize the "value network" of multi-group distributed collaborative operation based on electronic commerce by means of internet information technology; the construction of an electronic commerce value transmission network and a consumption capital network based on the Internet technology becomes a key direction of urgent need for the attraction and breakthrough in the whole electronic commerce industry.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a collaborative operation method based on electronic commerce and a distributed resale platform thereof, and the distributed resale online platform is adopted to track and trace commodity information and simultaneously limit transaction objects between two specific objects through the resale module, so that a network commerce mode of multi-object interweaving is realized.

The technical scheme adopted by the invention is as follows:

a collaborative operation method based on electronic commerce is used for determining attribution of commodity rights when on-line transaction is carried out by buyers and sellers.

The seller with commodity ownership carries out commodity ownership transaction with the buyer on line, records the ownership conversion process of each transaction, and the buyer obtaining commodity ownership after each transaction can select to resell or extract commodity again; the original buyer becomes a seller when resale is carried out, and online transaction is carried out on the same platform, and meanwhile transaction process information is recorded.

The invention relates to an electronic commerce collaborative operation method based on an online platform, which mainly constructs a commerce mode capable of carrying out intercommunication transaction aiming at all object types. Existing forms of electronic commerce include a variety of, for example, common business-to-business transactions, namely B2B; the business is also carried out between the enterprise and the consumer, namely B2C; consumer-to-consumer, referred to as C2C.

That is, the existing e-commerce modes are all to build a platform by using the internet as a carrier, but the types of the use objects of the platform are divided. The end-to-end and fixed object transaction mode can not well solve the problem that information can not be interacted and interacted because of the fact that commodity transaction between different objects must be carried out in a cross-platform mode. The invention provides a method, which is not limited to any object, can carry out synchronous online transaction aiming at ownership of the commodity, does not fix a buyer and a seller, and all users registered on the platform can be used as the seller or the buyer, and particularly depends on different object states in the transaction process.

For the buyer of each transaction, after the buyer reaches the offer and pays, the commodity distribution can be carried out off line on the existing electronic commerce platform, and once the transaction is completed and the right attribution of the commodity is confirmed without errors, the electronic commerce flow of the commodity is ended. If once the buyer wants to transfer ownership of the commodity again, this results in the commodity being defined as a second-hand commodity only and a second-hand transaction with the seller's identity on other cross-platforms only.

In this case, even if the commodity is not used, the commodity is directly determined as a second-hand commodity, and the value of the commodity is greatly reduced, resulting in a waste of value. And the commodity information can not be traced and traced on the basis of cross-platform selling on the secondhand transaction platform, even if the seller issues the original related information, the secondhand buyer can doubt the authenticity of the commodity information source.

The method of the invention changes the limitation of the object in the prior art, and has the same authority for all registered users, namely, after the online platform is registered as a user, commodity information can be submitted on the online platform for sale, but the commodity is originally put on the platform and is not extracted after the user purchases. Or the commodity meeting the commodity shelf requirement is regulated according to the platform. The commodity sales information issued on the platform can also be offered and the transaction flow is completed.

In order to avoid the problem that information faults are caused and the subsequent buyers cannot trace the whole transaction process and state information of the commodity, the method encrypts and stores the transaction process information of each time in a distributed mode, the buyers can check and verify the whole transaction process information of the commodity, and the state information of the commodity under the online condition can be checked, so that the concern of the buyers is eliminated, and the resale behavior of the commodity is not defined as second-hand commodity to be treated differently.

Further, when the seller performs commodity ownership resale transaction, the platform verifies the resale information of the seller, and generates an intelligent contract for the seller after the verification is successful; the buyer verifies his smart contract on the platform at the time of the transaction and then determines the payment.

Further, the intelligent contract is a data packet, the data packet comprises an encryption pointer based on a hash algorithm and a data set of the commodity right certificate, and the encryption pointer links the intelligent contract of the commodity at the last transaction.

Further, the whole collaborative operation method comprises the following specific steps:

s1, firstly registering on an online platform, and submitting commodity resale information with ownership to the platform by a user who purchases commodities at least once according to the identity of a seller;

s2, the platform examines the submitted resale information, generates an intelligent contract after confirmation and sends an offer invitation to a third party user;

s3, the third party user on the same platform submits commitment information according to the offer invitation, and responds to the offer by the identity of the buyer;

s4, the platform generates an intelligent contract according to the promise information, and the intelligent contract is confirmed to be effective after the buyer uploads payment information and is checked by the platform;

s5, the platform establishes the right conversion of both transaction sides and generates a new commodity right attributive certificate for the buyer, and simultaneously encrypts and stores the transaction process information;

s6, after obtaining ownership of the commodity, the buyer decides whether to resell or extract the commodity again.

G1. firstly, registering on an online platform, and uploading commodity information with ownership to the platform by a user with ownership of the commodity on the platform according to the identity of a seller;

G2. the platform audits the uploaded commodity information, generates an intelligent contract after confirmation and sends an offer invitation to a third party user;

G3. third party users on the same platform submit commitment information according to the offer invitation, and offer response is carried out according to the identity of the buyer;

G4. the platform generates an intelligent contract according to the promised information, and confirms that the intelligent contract is effective after the buyer uploads payment information and is checked by the platform;

G5. the platform establishes the right conversion of both transaction sides and generates a new commodity right attributive certificate for the buyer, and simultaneously encrypts and stores the transaction process information;

G6. after the buyer obtains ownership of the commodity, the buyer decides whether to resell or pick up the commodity again.

Further, the smart contract includes an encryption pointer and a commodity entitlement credential; the encryption pointer is used to link the smart contract at the time of the last transaction of the commodity.

The platform stores the transaction data of the commodity entitlement certificates each time so as to ensure that the ownership of the whole commodity can freely trade on the platform in the form of the electronic entitlement certificates and cannot be changed by serial. By adopting the block chain technology, the two nodes and the list hanging site of each transaction are used as block data to be stored in a distributed mode, and the next block contains a hash pointer for linking the previous block. Even if a third party wants to change one block data by using a device with high calculation power, the previous block data on the whole data chain needs to be changed by one time to succeed, and the block data of the single-station is stored in a hash mode based on a block set form and is stored in a distributed nested mode, and then more block hash changes are caused, so that the block data cannot be exhausted and finally fail.

In order to facilitate information tracing and avoid the commodity information being obtained by a third person except both transaction sides, a hash algorithm is adopted to encrypt the whole data chain, a longer character string is converted into a character string with a fixed length by adopting the hash algorithm, then a data block is obtained after encrypting each transaction process by adopting the hash algorithm, a pointer for linking the block is contained as the basic character string content of the next block, after the block data added in the current block set of the single-hanging site reaches a threshold value, the single-hanging site uses the hash algorithm to encrypt the whole block set containing the last newly added data block content again to obtain a block set hash pointer in the action process of the single-hanging site, and meanwhile the hash pointer for linking the block set is contained as the basic character string content of the creation block in the next block set. Each block is stored at different list-hanging site positions, and for the seller of the current transaction, a hash pointer pointing to the last transaction block can be obtained according to the block, and then the complete transaction record chain of the commodity after being put on the platform is obtained by back tracing layer by layer.

Further, the specific steps of the platform in step S2 for auditing the resale information during resale are as follows:

(2.1) firstly, determining resale information a according to commodity right information by a seller, and uploading the resale information a to a platform;

(2.2) the seller encrypts the resale information a through a hash algorithm to obtain a character string 1, simultaneously encrypts the character string 1 by adopting a private key obtained during registration to obtain a digital signature, and uploads the digital signature and a public key obtained during registration to a platform;

the platform encrypts the uploaded resale information a by adopting a hash algorithm to obtain a character string 2, and decrypts the digital signature by using a public key to obtain a character string 1;

and (2.4) comparing the character string 1 with the character string 2, if the character string 1 is matched with the character string 2, confirming that the list is valid for resale, generating a list block a, and if the character string is not matched with the list block a, confirming that the list is invalid and terminating the resale process.

Further, the specific steps of the platform in step S4 for verifying the payment information during payment are as follows:

(4.1) the buyer uploads payment information b based on the coupon block a to the platform;

(4.2) simultaneously encrypting the payment information b by the buyer by adopting a hash algorithm to obtain a character string 3;

(4.3) encrypting the character string 3 by the buyer by adopting the private key obtained during registration to obtain a digital signature, and uploading the digital signature and the public key obtained during registration to a platform;

(4.4) the platform adopts the same hash algorithm to obtain a character string 4 according to the payment information b, and adopts a public key to decrypt the digital signature to obtain a character string 3;

and (4.5) comparing whether the character string 3 and the character string 4 are matched, if so, the uplink confirmation simultaneously generates a payment block b and associates a list hanging block a, and if not, invalidation is performed, and the buyer is waited to upload the correct payment information b again.

The block chain encryption technology is adopted to carry out audit confirmation and uplink association on the whole resale transaction process, and meanwhile, the asymmetric encryption algorithm of a private key and a public key is adopted, so that the resale information or payment information is effectively prevented from being changed by others.

Firstly, a user must register first to become a system user, and the system returns a pair of public keys and private keys to the user;

two keys: public keys (public keys for short) and private keys (private keys for short). The public key and the private key are matched with each other for use, and if the data are encrypted by the public key, the data can be decrypted only by the corresponding private key. Because two different keys are used for encryption and decryption, the algorithm is an asymmetric encryption algorithm.

A distributed resale platform is used in the collaborative operation method based on electronic commerce, and comprises a main server and a list hanging site, wherein a callable resale module is arranged in the list hanging site, a seller carries out a resale process by calling the resale module, and the list hanging site examines the resale information and payment information to generate an intelligent contract and confirm whether the intelligent contract takes effect.

Further, each of the order hanging sites is attached with an identifier for each of the intelligent contracts.

The so-called identifier is a class label that is used to facilitate the system to quickly identify and determine to which transaction type, transaction area, transaction market, and service station the intelligent contract for the transfer of the commodity should belong.

The beneficial effects of the invention are as follows:

(1) The invention realizes the parallel of multiple identities of the same object based on the environment of the electronic commerce network by switching the identities of the object in the behavior of the electronic commerce network, so that the whole electronic commerce network is not limited to any single business form of B2B, B2C, C2C or C2B, and the like, but the multiple electronic commerce forms are in a free interweaving form based on the same electronic commerce network.

Through the method and the platform, any object in the electronic commerce network can purchase a certain commodity or an entitlement certificate by using the identity of the buyer, and can resell the purchased commodity or entitlement certificate by using the identity of the seller through calling a reselling module, so that a value transmission network based on the electronic commerce environment is constructed.

(2) According to the invention, each resale transaction can be traced back to the last intelligent contract through the encryption pointer generated based on the hash algorithm, and due to the irreversibility of the hash algorithm, the whole process tracing of transaction data information can be realized, and meanwhile, the non-stringable modification of data can be ensured. Thereby making up the deficiency of the current electronic commerce in commodity circulation traceability.

Detailed Description

The invention is further illustrated by the following description of specific embodiments in conjunction with the accompanying drawings.

The object referred to in the embodiments of the present application may be understood as all individuals or enterprises participating in the e-commerce network behavior. The node in the embodiment of the application may be understood as an abstract object that responds to a specific triggering condition of an external object in an e-commerce network and has an internal interaction rule, and the object may be set by an application program through a mobile phone, a tablet computer, a palm computer, a personal PC (personal computer) and other devices capable of realizing network communication so as to realize access control and data interaction to the node.

Example 1:

the embodiment is an electronic commerce collaborative operation method based on an online platform, as shown in fig. 1 and fig. 2, and mainly constructs a commerce mode capable of conducting intercommunication transactions for all object types. Existing forms of electronic commerce include a variety of, for example, common business-to-business transactions (B2B); also transactions (B2C) between the business and the consumer; transaction between consumers (C2C). The existing e-commerce modes are all to construct a platform by taking the Internet as a carrier, but the types of the application objects of the platform are divided. The end-to-end and fixed object transaction mode can not well solve the problem that information can not be interacted and interacted because of the fact that commodity transaction between different objects must be carried out in a cross-platform mode.

For the buyer of each transaction, after the buyer reaches the offer and pays, the commodity distribution is carried out off line on the existing electronic commerce platform, and once the transaction is completed and the commodity right is confirmed, the electronic commerce flow of the commodity is finished. If once the buyer wants to transfer ownership of the commodity again, this results in the commodity being defined as a second-hand commodity only and a second-hand transaction with the seller's identity on other cross-platforms only.

In this case, even if the commodity is not used, the commodity is directly determined as a second-hand commodity, and the value or price of the commodity is greatly reduced, resulting in a waste of value. And the commodity information can not be traced and traced on the basis of cross-platform selling on the secondhand transaction platform, even if the seller issues the original related information, the secondhand buyer can doubt the authenticity of the commodity information source.

In order to solve the existing problems, the cooperative operation method based on electronic commerce disclosed in this embodiment includes that a seller having commodity ownership performs commodity ownership transaction with a buyer on line, records a ownership conversion process of each transaction, and the buyer obtaining commodity ownership after each transaction can still select to resell or extract commodity again; the original buyer becomes a seller when resale is carried out, and online transaction is carried out on the same platform, and meanwhile transaction process information is recorded.

The method of the embodiment changes the limitation of the object in the prior art, and has free transaction authority for all registered users, namely after the online platform is registered as a user, commodity information can be submitted to the online platform for sale, but the commodity is originally put on the platform and is not extracted after the user purchases the commodity. Or the commodity meeting the commodity shelf requirement is regulated according to the platform, and the commodity sales information issued on the platform can be offered and the transaction flow can be completed.

When the seller performs commodity ownership resale transaction, the platform verifies the resale information of the seller, and generates an intelligent contract for the seller after the verification is successful; the buyer verifies his smart contract on the platform at the time of the transaction and then determines the payment.

The method comprises the following specific steps:

firstly, registering on an online platform, and at least purchasing a commodity user, changing an original buyer into a seller identity and submitting commodity resale information with ownership to the platform; or the user directly carries out sales hanging bill with the identity of the seller due to the initial ownership of the goods put on the platform.

And then, the platform carries out auditing on the uploaded commodity information, and sends an offer invitation to a third party user on line by taking the commodity as a target object after confirmation. The offer invitation here contains various means, such as products that are on-shelf in the corresponding marketing board, and that can be visually seen or searched by all users on the same platform, and that can also be actively recommended and information-contacted to the user with the demand on the corresponding marketing board on the platform. After the user obtains the offer invitation, uploading the nori information according to the self requirement, and responding the offer by the identity of the buyer; the platform facilitates the intelligent contract according to the promise information, and confirms that the intelligent contract is effective after the buyer uploads the payment information of the offer and is checked by the platform.

Then the platform establishes the right conversion of both transaction sides and generates new commodity right certificates for the buyer, and simultaneously encrypts and stores the information of the transaction process; the stored data blocks are distributed and stored at the positions of the hanging list sites and are synchronized to the positions of nodes of both sides of the transaction.

After the buyer obtains ownership of the commodity, whether the commodity is reselled or extracted again is determined, once the commodity picking step is completed, the transaction is a final node of the commodity based on platform circulation, the platform can carry out buffer storage treatment on the commodity based on the full-chain data related to the platform according to the temporary storage time of the data chain preset by the system, and once the temporary storage time exceeds the preset time, all the data chains corresponding to the commodity can be deleted.

In another aspect, the smart contract includes an encryption pointer and a commodity entitlement credential; the encryption pointer is used to link the smart contract of the last transaction of the commodity.

The storage of the intelligent contract data block is described, the platform stores the data of each commodity right transaction to ensure that the ownership of the whole commodity can freely trade in the form of an electronic right certificate on the platform and cannot be changed by a series of codes. By adopting the block chain technology, the two nodes and the list hanging site of each transaction are used as block data to be stored in a distributed mode, and the next block contains a hash pointer for linking the previous block. Even if one wants to change one block data by high calculation power, the previous block data on the whole data chain needs to be changed by one time to succeed, and the block data of the single-station is stored in a hash mode based on a block set and is stored in a distributed nested mode, so that more block hash changes are caused, the block data cannot be exhausted, and finally the block data fail.

In order to facilitate information tracing and avoid the commodity information being obtained by a third person except both transaction sides, a hash algorithm is adopted to encrypt the whole data chain, a longer character string is converted into a character string with a fixed length by adopting the hash algorithm, then a data block is obtained after encrypting each transaction process by adopting the hash algorithm, a pointer for linking the block is simultaneously contained as the basic character string content of the next block, after the block data added in the current block set of the single-hanging site reaches a threshold value, the single-hanging site uses the hash algorithm to encrypt the whole block set containing the last newly added data block content again to obtain a block set hash pointer in the single-hanging site action process, and meanwhile the hash pointer for linking the block set is contained as the basic character string content of the first block in the next block set. Each block data is stored in different list hanging site positions, and for the buyer and the seller of the current transaction, a hash pointer pointing to the last transaction block can be obtained according to the block data, and then the complete transaction record chain of the commodity after being put on the platform is obtained by back tracing layer by layer.

As shown in fig. 3, in step S2, the specific steps of the platform for auditing resale information at the time of resale are as follows:

firstly, a seller determines resale information a according to commodity right information and uploads the resale information a to a platform; the seller encrypts the resale information a through a hash algorithm to obtain a character string 1, encrypts the character string 1 by adopting a private key obtained during registration to obtain a digital signature, and uploads the digital signature and a public key obtained during registration to a platform; the platform encrypts the uploaded resale information a by adopting a hash algorithm to obtain a character string 2, and decrypts the digital signature by using a public key to obtain a character string 1; and comparing the character string 1 with the character string 2, if the character string 1 is matched with the character string 2, confirming that the list is valid for resale, generating a list block a, and if the character string is not matched with the character string, confirming that the list is invalid and terminating the resale process.

Similarly, as shown in fig. 4, the specific steps of the platform in step S4 for checking the payment information of the buyer during payment are as follows:

the buyer uploads payment information b based on the bill hanging block a to the platform; simultaneously, the buyer encrypts the payment information b by adopting a hash algorithm to obtain a character string 3; the buyer encrypts the character string 3 by using the private key obtained during registration to obtain a digital signature, and uploads the digital signature and the public key obtained during registration to the platform; the platform obtains a character string 4 by adopting the same hash algorithm according to the payment information b, and decrypts the digital signature by adopting the public key to obtain a character string 3;

by comparing whether the character string 3 and the character string 4 are matched, if so, the uplink confirmation simultaneously generates a payment block b and associates a list block a, if not, the payment block b is invalidated, and the buyer is waited to upload the correct payment information b again.

Firstly, a user firstly registers on the platform to become a system user, and the system returns a pair of public keys and private keys to the user. The public key and the private key are corresponding keys, and if the data are encrypted by the public key, the data can be decrypted only by the corresponding private key. Because two different keys are used for encryption and decryption, the algorithm is an asymmetric encryption algorithm. The basic process of realizing the secret information exchange by the asymmetric encryption algorithm is as follows:

the first party generates a pair of secret keys and discloses the public keys, and other roles (second party) needing to send information to the first party encrypt confidential information by using the secret keys (first party's public keys) and send the encrypted confidential information to the first party; and the first party decrypts the encrypted information by using the private key. In this way, even if the information is intercepted by another person, it is not decrypted because it has no private key of the first party. The opposite is true when the first party wants to reply to the second party, the public key of the second party is used for encrypting the data, and similarly, the second party can only use the private key of the second party for decrypting.

On the other hand, when transmitting information, encryption may be performed. The private key of the first party can be used for encrypting the confidential information to form a digital signature, and then the digital signature is sent to the second party; and the second party then carries out signature verification on the data sent by the first party by using the public key of the first party so as to determine whether the data is sent by the first party. Because the public key is disclosed in the whole network, the situation that false information is sent to the second party by the name of the first party can occur, and the first party can use the private key to carry out digital signature at the moment, so that the second party only receives a plurality of pieces of information from the true and false first party, but has the information of the digital signature of the first party and is from the true first party.

Meanwhile, the embodiment also comprises a distributed resale platform, namely a platform system based on the method. The system mainly comprises a main server and a list hanging site, wherein a callable resale module is arranged in the list hanging site, a seller performs a resale flow by calling the resale module, the list hanging site reviews the resale information and payment information, generates an intelligent contract and confirms whether the intelligent contract is effective, and accordingly, the rights of both transaction parties are established; the order hanging site is also a position for storing the distributed data blocks.

For any order hanging site in the e-commerce network, only when the order hanging site is used as a buyer request site and the promise of a buyer object is executed, and when the check of the payment information of the buyer is correct, a payment block based on the payment information certificate of the buyer is created based on the order hanging site and is associated with the order hanging block under the corresponding order hanging site. Otherwise, the order-hanging site only plays roles of consensus, propagation and sharing based on the intelligent contract of the e-commerce network.

That is, the order placing site of the seller and the order placing site of the buyer may not be the same, and the order placing site functions to generate an order placing block when acting on an order placing request of the seller, and functions to generate a payment block when acting on a payment request of the buyer. And the whole interaction of the offer information can be shared, propagated and shared among a plurality of order hanging sites.

In practice, the billing stations are divided according to the region where the billing stations are located, and a plurality of billing stations are obtained according to the administrative division mode of the region of province, city, district or county and the like, and meanwhile, corresponding service stations can be arranged for the same region so that the buyers can conveniently extract commodities.

Meanwhile, each order-placing site is attached with an identifier for each intelligent contract. The so-called identifier is a class label that is used to facilitate the system to quickly identify and determine to which transaction type, transaction area, transaction market, and service site the contract should be attributed.

The identified types are as follows:

in order to distinguish whether a commodity right is a direct sales order directly from a first commodity right person or a resale order based on the hands of a buyer; the intelligent closing date related to different hanging types is inconsistent.

In order to distinguish the area where the commodity right owner is located, for example, the positioning data of the commodity right owner is displayed on a achievement, the system can directly submit the order-hanging request to the order-hanging site corresponding to the achievement area when the order is hung, and if the positioning area does not have the corresponding order-hanging site, the system can submit the order-hanging request to the order-hanging site of the nearest area.

In actual operation, for administrative planning areas such as regional cities and counties, villages and towns and the like, a list hanging station is set according to local conditions.

For example, the commodity is expired for 90 days, or the commodity right makes price reduction resale, and the system hangs the commodity into a sales promotion special field; the sales promotion special field is a corresponding sales plate, can obtain higher-level display authority and information access on the platform, and can also appear in personalized recommendation or a recommended commodity list of related users.

The identifier is only used as a specific label to identify contract information of the commodity, identification confirmation is carried out while checking is carried out based on the object hanging list, and a corresponding identifier is attached after the identification is passed.

The buyer object is switched to the seller object and invokes the reselling module if the buyer object has completed at least one transaction in the e-commerce network system, and the commodity entitlement certificate of the right object of the transaction is present and the commodity is not extracted by the right person.

Meanwhile, the resale transaction flow between the buyer and the seller is based on a preset intelligent contract in the electronic commerce network, and once the object triggers the resale module, the system can automatically call and regularly execute the related content of the intelligent contract.

Example 2:

the embodiment is to perform optimization definition on the basis of the above embodiment 1, and provides a specific flow step for the resale module, which is specifically as follows:

firstly, a customer A resells a commodity A with ownership, calls a reselling module and enters a reselling process.

In fact, the online identification is that the client a pre-resells the right certificate of the commodity a, that is, a data block recording the right certificate of the commodity a, and after the block is hashed and encrypted, a corresponding hash value is obtained, and the hash value of the right certificate data block of the commodity a is assumed to be 0100.

The client A calls a resale module to submit the following relevant information in the resale information:

resale information a: commodity information A; the entitlement credential data block hash value for commodity a: 0100; resale price: 100 yuan; resale area: a capital is made;

the customer A encrypts resale information a by adopting an SHA256 algorithm to obtain a string of hash value binary character strings 1: XXXXX01 (actually a string of 256-bit 0 or 1 arranged character strings, abbreviated herein);

the client a then digitally signs the binary string 1 using its own private key.

Through the three steps, an encrypted data packet based on the resale information a and containing a digital signature is formed, which is called a smart contract a (because the smart contract a is an encrypted unilateral electronic offer invitation contract).

The client A takes the public key of the order-placing site a from the public key library in the system, then performs asymmetric encryption on the whole intelligent contract a and the data packet integrated with the resale information a, and then sends the data packet to the order-placing site a; this operation allows the packet to be viewed only after it has been decrypted by the order-pending site a with its corresponding private key.

After receiving the information data packet from the client A, the list hanging site a firstly uses the private key of the user to decrypt the information data packet to find out an intelligent contract a and resale information a; then begin for the two pieces of data: and respectively checking and verifying the intelligent contract a and the resale information a.

For the intelligent contract a, the order hanging site a firstly uses the public key of the client A to decrypt the digital signature, and a string of hash value binary character strings 1 are found in the intelligent contract a: XXXXX01, has no clear meaning.

For resale information a, the coupon site a uses the SHA256 algorithm to perform the same hash operation, and a string of hash value binary strings 2 is also obtained: XXXXX01;

the list hanging site a starts to compare the two character strings 1 and 2, and if the two character strings are completely consistent, the verification is passed; that is, the plaintext a corresponding to the encrypted binary string 1, which is not clearly understood for the string seen when the intelligent contract a was previously decrypted by the order placing site a, is the resale information a;

and the resale information a is not changed in a transmission process (because if a data packet is lost in data transmission or intercepted and changed by a person, the hash value character string 2 obtained by the same hash operation of the resale information a after the change is naturally completely different from the hash value character string 1 seen after the smart contract a is decrypted), and the data packet is confirmed to be sent out from the client A. Thus, the verification passes. Otherwise, the invalid discard is performed.

The order hanging site a generates an order hanging block a based on the order hanging request of the client A, establishes and generates an intelligent contract A and executes the intelligent contract A, sends the offer invitation to all order hanging sites in the achievement area (the client A explicitly designates a transfer sales area in the intelligent contract A: achievement) and performs global site consensus propagation. All third party buyers and objects belonging to the achievement area can see the commodity information in the node program, and can be understood as the commodity to be displayed. The buyer object decides whether to make a response promise to the offer invitation through the control node program.

Similarly, the verification of the buyer's response promise is similar to the process, and will not be repeated here.

On the other hand, the order placing station a only checks whether the resale information a is actually from the customer a and whether the data packet is changed in transmission.

As for the entitlement credential data hash value of that article a recorded in the resale information a: 0100 is true to all the customer nails, and the list hanging site a does not need to be repeatedly confirmed. Because the right confirmation process is already established by the bill hanging site involved in the last transaction process when the client A obtains the right certificate hash value of the commodity A, the bill hanging site is already established along with the completion of the last intelligent contract;

and the method and the device are used for tracing until the initial right certificate and the initial intelligent contract of the commodity A are found, so that the validity and the legality of the right certificate of the commodity A of the client methyl are established layer by layer.

Meanwhile, the right certificate of the commodity A is traceably confirmed by the system before the client A submits the resale list request, so that an entrance of the resale module naturally appears on a node program interface of the client A.

Otherwise, if the resale module entry does not appear on the node program interface of the client a, it indicates that the client a does not have any commodity entitlement certificate which can be handled by the client a, and then the resale module cannot be called, and the resale flow is entered.

In addition, when the user with the ownership of the goods on the platform uploads the goods information with ownership to the platform by the identity of the seller, initial auditing is needed, if the auditing standard is met, the goods are synchronously placed in a service station in the platform area, the goods information is uploaded to the platform, an initial right certificate of the goods is generated and issued by the platform, the object for providing the goods is an initial right person of the goods, and then the initial right person of the goods can only carry out order hanging sales or cancel the goods and return the goods through the platform. Thereby strictly establishing the validity and legitimacy of the initial entitlement credentials based on the commodity.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting. Although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical schemes described in the foregoing embodiments may be modified or some technical features may be replaced equivalently to achieve the same technical functions. Such modifications and substitutions do not depart from the spirit and purpose of the corresponding technical solutions of the embodiments of the present invention. Various other forms of product can be made by anyone with the teachings of the present invention. The above detailed description should not be construed as limiting the scope of the invention, which is defined in the claims and the description may be used to interpret the claims.

Claims
