Technical Field
The invention relates to the technical field of information, in particular to a virtual article transaction method, a virtual article transaction device, virtual article transaction equipment and a virtual article transaction storage medium.
Background
A virtual item may be an item of value consisting of an irregular sequence of characters, as opposed to a physical item. Such as a stored value card redemption code, a rights and interests activation code, a telephone fee recharge code, an account number recharge code, game items, and the like. The virtual goods need to be converted into corresponding rights and interests after the activation and exchange of the appointed virtual goods issuer. Like physical goods, people also have trade needs for virtual goods. The transaction of the virtual article can be one-to-one, face-to-face, offline, or online, such as via an instant messaging tool or a transaction platform.
Unlike physical item transactions, virtual item transactions present some serious security concerns. For example, a porcelain hit by the purchaser may occur during the transaction. The buyer successfully redeems the virtual goods after receiving the virtual goods, then misreads the virtual goods sent by the seller, and seeks to resend the new virtual goods by the seller.
The above-mentioned problems are transaction disputes that are common in the virtual article transaction process, and the above-mentioned problems are spread around the authenticity of the virtual article, and disputes occur because the authenticity of the virtual article cannot be guaranteed in the transaction process.

Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
An embodiment of the present invention provides a virtual article transaction method, as shown in fig. 1, the virtual article transaction method according to the embodiment of the present invention includes:
step S110, receiving a virtual article transaction request from a virtual article seller, wherein the virtual article transaction request comprises information of a first identifier;
step S120, sending the virtual article transaction request to a virtual article issuer;
step S130, receiving information of a second identifier from the virtual article issuer, wherein the information of the second identifier is obtained by replacing the information of the first identifier by the virtual article issuer;
in step S140, the information of the second identifier is provided to the virtual item purchaser.
In a possible implementation manner, the virtual article transaction method provided by the embodiment of the invention can be applied to a transaction server.
In the virtual article transaction process, the key to solve the dispute problem is that only one buyer in both transaction parties can use the virtual article. In the embodiment of the invention, the transaction server firstly sends the information of the first identifier in the transaction request from the virtual article seller to the virtual article issuer. The information of the first identifier may be a segment of character combination string code for identifying the virtual object, or may be an identifier code of other forms. And then the virtual article issuer carries out replacement processing on the information of the first identifier to obtain the information of the second identifier, and returns the information of the second identifier to the transaction server. And finally, the transaction server provides the information of the second identifier to the virtual article purchaser. Wherein the replacement process may include a fidelity replacement of the information of the first identity. The fidelity replacement is a service provided by an article issuer, and the main purpose of the fidelity replacement is to ensure that the information of the first identifier of the transaction is only known by one buyer, so that the dispute between the seller and the buyer of the transaction about the true and false character combination string code is solved.
One of the above technical solutions has the following advantages or beneficial effects: by replacing the information of the first identifier, the information of the first identifier of the transaction can be ensured to be known by only one buyer, so that the dispute problem of true and false identifiers between a seller and a buyer of the transaction is solved to a certain extent, and the possibility of dispute in the virtual article transaction process is reduced.
The implementation manner of the transaction server can include different implementation manners such as private service or block chain distributed service. For example, a private cloud server may be built for individual use by one customer and thus may provide effective control over data, security, and quality of service.
As mentioned above, the key to solving the dispute problem that may exist in virtual article transaction is how to ensure that the virtual article is real and effective in the whole transaction process. Due to the characteristics of decentralized block chain, non-falsifiable data, traceability and the like, the intelligent contract of the block chain can be used as the transaction server in the embodiment of the invention, and the virtual article transaction method in the embodiment can be executed.
An intelligent contract is a set of commitments defined in digital form, including agreements on which contract participants can execute the commitments. That is, a smart contract is a set of protocols that can automatically perform certain tasks. An intelligent contract is equivalent to building a contract in a computer system that is readable by each participant. Briefly, a smart contract is a piece of code written on a blockchain. When a certain event is triggered, the intelligent appointment is executed immediately. If complex business logic needs to be completed by using the blockchain technology, intelligent contracts need to be deployed on the blockchain, and the execution of codes in the intelligent contracts is triggered when the blockchain detects that certain specific data meets a preset condition. The logic processing related to the embodiment of the invention can be deployed on the block chain by creating the intelligent contract so as to complete the transaction process of the virtual article.
Specifically, in step S110, the smart contract receives a virtual item transaction request from a virtual item seller, where the virtual item transaction request includes information of the first identifier of the virtual item requesting the transaction and may further include information of the buyer. In step S120, the smart contract sends the virtual good transaction request to the virtual good issuer, so that the virtual good issuer performs fidelity replacement on the information of the first identifier to obtain information of the second identifier. In steps S130 and S140, the smart contract receives the information of the second identifier from the virtual item issuer and provides the information of the second identifier to the virtual item purchaser.
In one embodiment, said sending said virtual good transaction request to a virtual good issuer comprises:
and encrypting the virtual article transaction request by using a first encryption mode to obtain a ciphertext of the virtual article transaction request, and sending the ciphertext of the virtual article transaction request to the virtual article issuer.
In one example, the first encryption mode may use an asymmetric encryption algorithm for encryption, such as an RSA encryption algorithm. Since RSA is proposed by Ronad Livister (Ron Rivest), Adi Samor (Adi Shamir), and Ronad Adleman (Leonard Adleman), the RSA algorithm is named by the initial letters of their three surnames. In the above embodiment, the first encryption scheme may encrypt the virtual good transaction request based on a public key provided by a virtual good issuer to which the virtual good belongs.
Fig. 2 is a schematic data interaction diagram of a virtual article transaction method according to an embodiment of the present invention. As shown in fig. 2, when a seller needs to sell a virtual article to a buyer, information of a first identifier of the virtual article, such as a segment of string code, is first submitted to an intelligent contract of a block chain. At this time, the intelligent contract receives the information of the first identifier of the virtual article sent by the seller and automatically triggers the execution operation, wherein the execution operation may include:
1) the character combination string code of the virtual article is RSA encrypted according to the public key provided by the virtual article issuer to which the virtual article belongs, and is transmitted to the interface service provided by the virtual article issuer to which the virtual article belongs. Wherein the public key provided by the virtual good issuer is provided when the virtual good issuer is registered on the smart contract, and the private key is maintained by the virtual good issuer.
2) Waiting for the return of the virtual good issuer's interface service.
Wherein the returning of the interface service of the virtual good issuer comprises: the virtual article issuer detects whether the character combination string code is valid. And if the character combination string code is invalid, returning error information to the intelligent contract. If the character string code is valid, then the character string code is subjected to fidelity replacement to generate a new character string code with equivalent value and other utilities, namely the information of the second identifier. The information of the second identifier is then transmitted back to the smart contract in RSA-encrypted form. Fig. 3 shows a service processing flow of a virtual article issuer of the virtual article transaction method according to an embodiment of the present invention.
In one embodiment, said receiving information from said second identifier of said virtual good issuer comprises: receiving a first ciphertext of the second identification from the virtual article issuer;
the providing the information of the second identification to the virtual item purchaser comprises: decrypting the first ciphertext of the second identifier to obtain a plaintext of the second identifier; encrypting the plaintext of the second identifier by using a second encryption mode to obtain a second ciphertext of the second identifier; providing the second cryptogram of the second identification to the virtual item purchaser.
In one example, the second encryption scheme may employ an asymmetric encryption algorithm for encryption, such as an RSA encryption algorithm. The second encryption mode is to encrypt the plaintext of the second identifier by the public key of the purchaser.
Referring to fig. 2, the smart contract receives the encrypted new virtual article with utility such as equivalent value from the virtual article issuer, for example, receives a new character combination string code with utility such as equivalent value, decrypts the character combination string code, encrypts the character combination string code with the public key of the purchaser, and stores the encrypted character combination string code in the user transaction data table in the form of ciphertext. The public key of the purchaser is automatically generated when the purchaser performs user registration and is stored in the user data table, and the private key of the purchaser is stored offline by the purchaser.
In one embodiment, said providing the information of the second identity to the virtual good purchaser comprises:
and returning the information of the second identification to the virtual item purchaser in response to a viewing request of the virtual item purchaser.
Referring to FIG. 2, when the buyer needs to view the information of the second identifier of the virtual item, the intelligent contract will return the user transaction record of the buyer in the user transaction data table. The purchaser decrypts locally to obtain the final fidelity-converted character combination string code. No third party can obtain the character combination string code in the whole process, and the absolute safety of the character combination string code is guaranteed.
Because the virtual article transaction mode is an online mode, if an encryption mode is not adopted, the transmission process or the storage process may suffer from the problem of data theft. In the embodiment of the invention, in the whole transaction process, the data transmission and storage are encrypted by adopting an asymmetric encryption algorithm, so that the data security is ensured and the data cannot be stolen by any third party.
Another technical scheme in the above technical scheme has the following advantages or beneficial effects: data transmission and storage in the transaction process are encrypted by adopting an encryption algorithm, so that the data security is ensured, and the possibility that the virtual goods are stolen in the transaction process is greatly reduced. The safe transaction environment can ensure the smooth transaction and further stimulate the increase of the transaction amount.
In one embodiment, the method further comprises:
and if the error information from the virtual article issuer is received, sending the error information to the virtual article seller.
As described above, after receiving a virtual article transaction request sent by a seller, the intelligent contract transmits the transaction request to the interface service provided by the virtual article issuer to which the transaction request belongs, and waits for the return of the interface service of the virtual article issuer. The returning of the interface service of the virtual good issuer includes: the virtual article issuer detects whether the character combination string code is valid. And if the string code is invalid, returning error information to the intelligent contract.
In one embodiment, upon receiving the error message from the virtual good issuer, the smart contract sends a corresponding error prompt to the virtual good seller and terminates the transaction. In another embodiment, upon receiving the error message from the virtual good issuer, the smart contract sends a corresponding error prompt message to the virtual good seller. And according to the error prompt message, the virtual article seller terminates the transaction or resends the virtual article transaction request.
An embodiment of the present invention provides a method for virtual item transaction, and as shown in fig. 4, the method for virtual item transaction of the embodiment of the present invention includes:
step S410, receiving a virtual article transaction request from a transaction server, wherein the virtual article transaction request comprises information of a first identifier;
step S420, the information of the first identification is replaced to obtain the information of a second identification;
step S430, returning the information of the second identifier to the transaction server.
In a possible implementation manner, the virtual article transaction method provided by the embodiment of the invention can be applied to a virtual article issuer.
As described above, in the virtual article transaction process, the key to solving the dispute problem is how to ensure the authenticity of the virtual article and only one of the two parties of the transaction can use the virtual article. In the embodiment of the invention, the transaction server sends the transaction request of the virtual article to the virtual article issuer, wherein the transaction request comprises the information of the first identifier. For example, the first identified information may be a segment of a string code identifying the virtual item. And then the virtual article issuer replaces the information of the first identifier to obtain the information of the second identifier and returns the information of the second identifier to the transaction server. Wherein the replacement process may include a fidelity replacement of the information of the first identity. The fidelity replacement is a service provided by the goods issuer, and the main purpose of the fidelity replacement is to ensure that the information of the first identifier of the transaction is only known by one buyer, for example, the character combination string code for identifying the virtual goods is only known by one buyer, even is unknown to the seller, which can solve the dispute between the seller and the buyer about the true and false character combination string code to some extent. In one example, the information of the first identifier is in the form of a character combination string code, and the fidelity permutation may include: 1) setting the character combination string code of the seller to be in a failure state; 2) and generating a new string code with equivalent value and equal effect.
In addition, due to the characteristics of decentralized block chain, data non-falsification, traceability and the like, the intelligent contract of the block chain can be used as the transaction server in the embodiment of the invention.
One of the above technical solutions has the following advantages or beneficial effects: by replacing the information of the first identifier, the information of the first identifier of the transaction can be ensured to be known by only one buyer, so that the dispute problem of true and false identifiers between a seller and a buyer of the transaction is solved to a certain extent, and the possibility of dispute in the virtual article transaction process is reduced.
Fig. 5 is a flow chart of information replacement of the virtual article transaction method according to the embodiment of the present invention. As shown in fig. 5, in an embodiment, the replacing the information of the first identifier to obtain information of a second identifier includes:
step S510, determining whether the information of the first identifier is valid;
step S520, if the information of the first identifier is valid, the information of the first identifier is replaced to obtain the information of the second identifier, and the information of the first identifier is set to be in an invalid state.
One of the potential safety hazards in virtual item transactions is fraudulent shipping. The virtual item has already been redeemed by the seller at the time of sale of the virtual item. At this point the virtual item has failed, yet the seller still intentionally sells the failed virtual item to the purchaser. The purchaser therefore fails to purchase a valid virtual item, but at this point the money has been paid to the seller.
In view of this, the interface service of the virtual article issuer performs an authenticity check on the information of the first identifier, that is, determines whether the information of the first identifier is valid. If the information of the first identifier is in the form of a string code, an exemplary verification method includes: and pre-storing the effective character combination string code in a database of a virtual article issuer, and comparing the effective character combination string code with data in the database to verify the authenticity of the character combination string code. If the information of the first identification is valid, the character combination string code provided by the seller is subjected to fidelity replacement to obtain a new string code with equivalent value and other effects, and the character combination string code provided by the seller is set to be in a failure state.
Referring to fig. 5, in one embodiment, the method further comprises:
step S530, if the information of the first identifier is invalid, returning an error message to the transaction server.
In the above example, if the character combination string provided by the seller is an invalid string, it is immediately returned to the intelligent contract, and the intelligent contract sends a corresponding error prompt to the virtual goods seller and terminates the transaction. Or the intelligent dating point sends corresponding error prompt information to the virtual article seller, so that the virtual article seller terminates the transaction or resends the virtual article transaction request according to the error prompt information.
In one embodiment, the virtual item transaction request includes a cryptogram of the first identifier;
the replacing the information of the first identifier to obtain the information of the second identifier includes: and decrypting the ciphertext of the first identifier to obtain a plaintext of the first identifier, and replacing the plaintext of the first identifier to obtain a plaintext of a second identifier.
In one embodiment, said returning information of said second identity to said transaction server comprises:
and encrypting the plaintext of the second identifier to obtain a ciphertext of the second identifier, and returning the ciphertext of the second identifier to the transaction server.
In the above process, the encryption and decryption processes may also be performed by using an asymmetric encryption algorithm, for example, an RSA encryption algorithm.
Another technical scheme in the above technical scheme has the following advantages or beneficial effects: data transmission and storage in the transaction process are encrypted by adopting an encryption algorithm, so that the data security is ensured, and the possibility that the virtual goods are stolen in the transaction process is greatly reduced.
Fig. 3 is a service processing flow chart of a virtual article transaction method according to an embodiment of the present invention. As shown in fig. 3, in step 3.1, after receiving the virtual article in the encrypted transaction request transmitted by the intelligent contract, the interface service of the virtual article issuer first performs RSA decryption to obtain the plaintext virtual article character combination string code. And then executing step 3.2, the interface service of the virtual article issuer carries out authenticity check on the character combination string code, and judges whether the character combination string code is real and available. If the string code is not available, i.e. in case of an invalid string code, an error code is returned in the result information returned to the smart contract in step 3.4, so that the smart contract sends a corresponding error prompt to the virtual goods seller and terminates the transaction. If the character combination string code is truly available, that is, the case of a valid string code, step 3.3 is executed to perform a fidelity replacement operation, and the received virtual article is invalidated to generate a new equivalent virtual article. Namely, the original character combination string code is set to be in a failure state, and a section of new string code with equivalent value and other effects is produced at the same time. In step 3.4, the generated new string code will be transmitted back to the smart contract in RSA encrypted form.
The embodiment of the invention also provides a virtual article transaction device which can be applied to a transaction server.
