[0084] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0085] In the technical solutions of the present application, the acquisition, storage, use, processing, etc. of data all comply with the relevant regulations of national laws and regulations.

[0086] Considering the problem that in the prior art, the real address (account number) of the payee is exposed to the payer for payment, which is not conducive to the privacy protection of users, the present application provides a blockchain privacy payment method, device, and system. A pseudo-address payment QR code is generated through a unique key value corresponding to the real blockchain address of the receiving user node for the payment operation of the paying user node, and the original image resources are provided to the paying user node through the application server node after the payment is completed, thereby effectively protecting the privacy of the account address in the blockchain payment transaction.

[0087] To effectively protect the privacy of account addresses in blockchain payment transactions, this application provides an embodiment of a blockchain privacy payment method. The execution entity is an application server node in the blockchain network. The application server node is connected to the receiving user node and the paying user node in the blockchain network. Refer to Figure 1 The blockchain privacy payment method specifically includes the following content:

[0088] Step S101: Receive the original image resource, unique key value, and pseudo-address payment QR code sent by the receiving user node in the blockchain network. Among them, the unique key value is obtained from the blockchain real address of the receiving user node, and the pseudo-address payment QR code is obtained from the blockchain real address and the unique key value.

[0089] Optionally, the original image resource is, for example, an image or a video. The original image resource may refer to the image data that the receiving user node wants to charge for viewing, such as a chargeable picture.

[0090] Optionally, according to the prior art, the real address d of the receiving user node in the blockchain network a Except for the first digit as the type identifier, the rest is the public key k p Obtained through a certain compression transformation (such as Hash, base58 encoding). Therefore, this application can perform a hash process on this real address d a To obtain a unique key value P corresponding to the real address x (For example, P x = Hash(x)), where x refers to the real address d of the receiving user node a , or it can also refer to the real address of a certain picture x in the blockchain.

[0091] Optionally, in order not to expose the real address of the receiving user node, this application can further use this unique key value P x To obtain a pseudo-address payment QR code V through a reversible operation ax , for example:

[0092]

[0093] Among them, the reversible operation is, for example, a simple ordinary addition, or a complex arbitrary monotonic function, and its operator is denoted as Its inverse operation is denoted as

[0094] Thus, V ax Is the pseudo-address of the receiving user node a based on the picture x. Therefore, different pictures x have different pseudo-addresses V ax, although these pseudo-addresses are different, the same real address d can be obtained from the above formula a (i.e., the real address of the receiving user node a).

[0095] Step S102: Receive the image resource payment signal sent by the payment user node in the blockchain network, where the image resource payment signal is generated after the payment user node scans the pseudo-address payment QR code and completes the payment operation.

[0096] Optionally, the receiving user node of the present application can complete the payment operation by scanning the pseudo-address payment QR code and send the generated image resource payment signal to the application server node in the blockchain network. The application server node stores the original image resource, unique key value, and pseudo-address payment QR code uploaded by the receiving user node.

[0097] Step S103: Determine the corresponding unique key value according to the image resource payment signal, and determine the blockchain real address of the receiving user node according to the unique key value and the pseudo-address payment QR code corresponding to the image resource payment signal.

[0098] Optionally, since the application server node stores the original image resource, unique key value, and pseudo-address payment QR code uploaded by the receiving user node, the smart contract of the application server node of the present application can query the unique key value P corresponding to the image resource payment signal according to the preset index table x , and based on this unique key value P x perform an inverse operation on the pseudo-address payment QR code V corresponding to the image resource payment signal ax to obtain the blockchain real address d of the receiving user node a , and the specific formula is, for example:

[0099]

[0100] Step S104: Transfer the payment amount corresponding to the image resource payment signal to the blockchain real address of the receiving user node, and return the original image resource to the payment user node.

[0101] From the above description, it can be seen that the blockchain privacy payment method provided by the embodiments of the present application can generate a pseudo-address payment QR code through the unique key value corresponding to the blockchain real address of the receiving user node for the payment operation of the payment user node, and provide the original image resource to the payment user node through the application server node after the payment is completed, thereby effectively protecting the privacy of the account address in the blockchain payment transaction.

[0102] In order to determine the corresponding unique key value according to the payment signal of the image resource, in an embodiment of the blockchain privacy payment method of the present application, refer to Figure 2 , the above step S103 may further specifically include the following content:

[0103] Step S201: Determine the corresponding pseudo-address payment QR code according to the payment signal of the image resource.

[0104] Step S202: Determine the corresponding unique key value according to the preset index table and the pseudo-address payment QR code, wherein the preset index table stores the unique key value sent by the receiving user node, the pseudo-address payment QR code, and the corresponding relationship between the unique key value and the pseudo-address payment QR code.

[0105] Optionally, since the application server node stores the original image resource, the unique key value, and the pseudo-address payment QR code uploaded by the receiving user node, the smart contract of the application server node of the present application can query the unique key value P corresponding to the payment signal of the image resource according to the preset index table x , and based on this unique key value P x perform an inverse operation on the pseudo-address payment QR code V corresponding to the payment signal of the image resource ax to obtain the blockchain real address d of the receiving user node a , and the specific formula is for example:

[0106]

[0107] Specifically, refer to Figure 15 , P x that is, the unique key value of the foregoing picture x, can be regarded as a pointer pointing to picture x in the picture library, V ax that is, the pseudo-address payment QR code, W x external identifiers such as: picture name, author, number, etc., W x can be retrieved on the terminal of user b (i.e., the payment user node) and can be selected.

[0108] In order to accurately determine the blockchain real address of the receiving user node, in an embodiment of the blockchain privacy payment method of the present application, the above step S103 may further specifically include the following content:

[0109] Perform an inverse operation according to the unique key value and the pseudo-address payment QR code corresponding to the payment signal of the image resource to obtain the blockchain real address of the receiving user node, wherein the pseudo-address payment QR code is obtained by performing a reversible operation on the unique key value and the blockchain real address.

[0110] Optionally, in order not to expose the real address of the payee user node, the present application may further utilize the unique key value P x to obtain a pseudo-address payment QR code V through a reversible operation ax , for example:

[0111]

[0112] Among them, the reversible operation is, for example, a simple ordinary addition or a complex arbitrary monotonic function, and its operator is denoted as and its inverse operation is denoted as

[0113] Thus, V ax is the pseudo-address of the payee user node a based on the picture x. Therefore, different pictures x have different pseudo-addresses V ax , although these pseudo-addresses are different, the same real address d a (i.e., the real address of the payee user node a) can be obtained from the above formula.

[0114] In order to ensure information security, in an embodiment of the blockchain privacy payment method of the present application, refer to Figure 3 , after the above step S103 and before the above step S104, the following content may also be specifically included:

[0115] Step S301: Obfuscate the original image resource according to the pseudo-address payment QR code.

[0116] Step S302: Send the original image resource after obfuscation processing to the payer user node for display.

[0117] Specifically, refer to Figure 14 , the payer user node (such as user b) can see the picture x and the pseudo-address payment QR code V on the computer or mobile phone screen ax , the application server node of the present application can obfuscate the pseudo-address payment QR code V ax with the picture x (such as picture overlay) and then transmit it to the front end of user b for display. Since user b does not obtain all of the picture x (the part blocked by V ax is not obtained), thus P x cannot be obtained, so even if the relevant algorithm is known, d a cannot be obtained, thereby realizing the confidentiality of the real address d a .

[0118] In order to effectively protect the privacy of the account address in blockchain payment transactions, an embodiment of a blockchain privacy payment method is provided in this application. The execution entity is the receiving user node in the blockchain network. The receiving user node is connected to the application server node and the paying user node in the blockchain network. See Figure 4 , and the blockchain privacy payment method specifically includes the following content:

[0119] Step S401: Determine the corresponding unique key value according to the blockchain real address.

[0120] Step S402: Send the blockchain real address, the unique key value, and the original image resource to the application server node in the blockchain network, so that after the application server node receives the image resource payment signal sent by the paying user node in the blockchain network, it determines the corresponding unique key value according to the image resource payment signal, determines the blockchain real address of the receiving user node according to the unique key value and the pseudo-address payment QR code corresponding to the image resource payment signal, transfers the payment amount corresponding to the image resource payment signal to the blockchain real address of the receiving user node, and returns the original image resource to the paying user node, where the image resource payment signal is generated after the paying user node scans the pseudo-address payment QR code and completes the payment operation.

The pseudo-address payment QR code is obtained from the blockchain real address and the unique key value of the receiving user node in the blockchain network, and the unique key value is obtained from the blockchain real address of the receiving user node.
