1. the invention can perform one-to-one correspondence to the commodity and the identification code, and correspondingly store the transportation information and the circulation information of the commodity by combining the blockchain so as to assist a user in tracing the commodity and reduce the counterfeiting rate of the commodity. The invention can uplink and store the transportation information and the circulation information of the commodity into the corresponding commodity nodes of the tracing blockchain according to the unique identification code of the commodity, and can correspondingly trace the transportation information and the circulation information of the commodity. When the circulation information of the commodities is stored in the corresponding commodity nodes of the traceability block chain in an uplink mode, the unique identification code of each commodity is in one-to-one correspondence with the identity information of the corresponding purchasing end, the attribute of the unique identification code is converted into the circulation code from the transportation code, each circulation code can only correspond to one identity information, only the holder of the commodity corresponding to the circulation code can verify the circulation code, and other people cannot verify the circulation code, so that the probability of imitation of the circulation code is reduced. When the commodity corresponding to the purchasing end is transferred, the invention also generates a corresponding transfer interface corresponding to the purchasing end, transfers the commodity required to be transferred by the purchasing end through the transfer interface, generates a transcoding interface according to the transfer interface, and uniformly replaces and updates the identity information of the commodity transferred through the transcoding interface, so that the identity information corresponding to the transfer code of each commodity can correspond to the identity information of the actual user of the commodity.

2. When the circulation interface is generated, the circulation interface is divided into a resale interface and an identity interface, the resale interface is used for displaying data information of the resale commodity, and the identity interface is used for displaying identity information of the circulated end. When the circulation quantity is greater than 1, the invention can obtain the area ratio of the resale interface and the identity interface according to the circulation quantity, and then carry out interface division, so that the area ratio of the resale interface and the identity interface can be dynamically adjusted by combining the quantity of the circulated commodities. When the circulation quantity is larger than 1, the invention also generates the data filling area corresponding to each circulation commodity and arranges the data filling area in the resale interface according to different arrangement modes, wherein the data filling area comprises the image filling area of the preset image corresponding to each commodity and the commodity code filling area to be scanned, so that the circulation terminal can upload the circulation code corresponding to the corresponding commodity according to the preset image corresponding to each commodity in the resale interface at the subsequent time, and provides guidance for the circulation terminal when uploading the circulation code. When the data filling areas corresponding to the commodities are arranged, the invention adopts two modes to arrange the data filling areas corresponding to the commodities, one mode is to arrange and display the data filling areas corresponding to the commodities in the display areas directly and randomly, the other mode is to arrange and display the data filling areas with the same commodity types in the display areas, when the data filling areas are arranged according to the first mode, the area proportion of each display area is the same, and when the data filling areas are arranged according to the second mode, the area proportion of each display area corresponds to the proportion of the commodity numbers in the commodity type collection of the corresponding type, by the mode, the data filling areas corresponding to the commodities can be displayed in a resale interface, so that a circulation terminal can upload circulation codes corresponding to the commodities according to preset images corresponding to the commodities in the resale interface, and the second arrangement mode can also arrange and display the data filling areas with the same commodity types in groups.

3. When the transcoding interface is generated according to the streaming interface, the streaming interface is sent to the corresponding streaming terminal, and then the transcoding interface is generated according to the streaming terminal based on the streaming transcoding uploaded by the streaming interface. Specifically, after receiving the commodity codes uploaded by the circulation terminal based on the data filling area in the circulation interface, the invention performs double verification on the identity information and the corresponding information of the commodity codes, and only when the identity information corresponding to the commodity codes and the identity information corresponding to the data filling area are consistent, and the commodity images corresponding to the commodity codes and the preset images corresponding to the data filling area are also consistent, the invention can correspond the commodity corresponding to the commodity codes and the commodity corresponding to the data filling area, and fill the corresponding circulation code into the commodity code filling area in the data filling area to obtain the commodity corresponding area, and obtain the transcoding interface according to the commodity corresponding area, so that the corresponding circulation code identity information can be converted and updated according to the transcoding interface, and the corresponding circulation code identity information can be updated into the circulation terminal identity information, so that the corresponding circulation code identity information can correspond to the identity information of the actual user of the commodity.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, a flow diagram of a cross-border supply chain commodity tracing method based on a blockchain according to an embodiment of the present invention is shown, where an execution subject of the method shown in fig. 1 may be a software and/or hardware device. The execution bodies of the present application may include, but are not limited to, at least one of: user equipment, network equipment, etc. The user equipment may include, but is not limited to, computers, smart phones, personal digital assistants (Personal Digital Assistant, abbreviated as PDA), and the above-mentioned electronic devices. The network device may include, but is not limited to, a single network server, a server group of multiple network servers, or a cloud of a large number of computers or network servers based on cloud computing, where cloud computing is one of distributed computing, and a super virtual computer consisting of a group of loosely coupled computers. This embodiment is not limited thereto. The method comprises the steps S1 to S5, and specifically comprises the following steps:

S1, generating commodity nodes according to unique identification codes of cross-border commodities, generating a tracing blockchain based on each commodity node, generating a transportation code based on the unique identification codes, acquiring transportation information of the corresponding cross-border commodities according to the transportation code, and storing the transportation information in an uplink mode to the tracing blockchain, wherein the transportation information comprises logistics information and supervision information.

It can be understood that, in order to reduce the probability that the identification code corresponding to the commodity is imitated, the unique identification code corresponding to each commodity is generated, that is, the unique identification code is then stored in the corresponding commodity node of the traceable blockchain in an uplink manner according to the transportation information and the subsequent circulation information of the commodity by the unique identification code, and in practical application, the unique identification code can be an entity two-dimensional code corresponding to the commodity.

When the transportation information of the commodities is stored in the source tracing blockchain in a uplink mode according to the unique identification codes, commodity nodes corresponding to the commodities can be generated firstly, then the transportation codes are generated according to the unique identification codes corresponding to the commodities, the transportation codes are identical to the unique identification codes, the attribute of the unique identification codes is only converted, then the transportation information of the corresponding cross-border commodities is obtained according to the transportation codes, and the transportation information is stored in the corresponding commodity nodes of the source tracing blockchain in the uplink mode.

In practical application, the logistics information and the supervision information corresponding to the transportation information can be stored in corresponding commodity nodes of the traceable blockchain in an uplink mode, wherein the logistics information can comprise logistics information such as the country of origin, the country of departure, the port of loading, the transportation mode, the bonded warehouse and the like of corresponding commodities, and the supervision information can comprise supervision information such as the entrance zone customs, the exit zone customs, the declaration serial numbers corresponding to the entrance zone customs and the exit zone customs of the corresponding commodities.

By the method, the transportation information corresponding to each commodity can be stored according to the traceability blockchain, so that the transportation information of each commodity can be traced back through the traceability blockchain.

S2, acquiring purchase information of a purchase end, determining transportation information of commodity nodes corresponding to a tracing blockchain according to the purchase information, sending the transportation information to the purchase end, extracting first identity information of the purchase end after receiving confirmation information of the purchase end, converting the attribute of the transportation code of the corresponding cross-border commodity according to the first identity information to obtain a first stream transcoding, and storing the first stream transcoding into the corresponding commodity nodes.

In practical application, when a user purchases a corresponding commodity based on a purchasing end, the transportation information corresponding to the corresponding commodity can be sent to the purchasing end for checking, then the first identity information of the user is obtained after the user clicks the confirmation information based on the purchasing end, the first identity information corresponds to the unique identification code of the commodity purchased by the user based on the purchasing end, and the first stream transcoding after attribute conversion is obtained, so that each commodity corresponds to a purchaser one by one, and the first stream transcoding of each commodity only corresponds to one identity information.

After the first stream transcoding corresponding to the corresponding commodity is obtained, if other purchasing ends upload the same first stream transcoding, the commodity purchased by the purchasing end is quite likely to be imitated, and in this case, an imitated prompt can be generated and sent to the corresponding purchasing end to prompt the purchasing end.

Since the corresponding commodity enters the circulation process after being purchased by the user based on the purchasing end, the attribute of the transportation code is changed at this time, and the circulation transcoding is changed.

Through the mode, each commodity and the purchasers of the commodity can be in one-to-one correspondence, and the probability of imitation of the identification code corresponding to the commodity is reduced, so that the imitation rate of the commodity can be reduced.

S3, receiving second identity information and commodity demand information of the turned-over ends, determining corresponding purchasing ends as turning-over ends according to the commodity demand information, generating turning-over interfaces corresponding to the turning-over ends according to the turning-over numbers, receiving first stream transcoding of the turning-over ends based on the turning-over interfaces, and generating a transcoding interface.

In practical application, after the user purchases the corresponding commodity based on the purchasing end, the corresponding commodity may be reselled to other people, in this case, the occupant of the corresponding commodity may change, the identity information corresponding to the first transcoding may also change, and if the identity information corresponding to the first transcoding is not updated, the correspondence between the transcoding and the identity information may be unavailable, so that a problem may occur during identity verification.

Specifically, the invention firstly receives the second identity information and the commodity demand information uploaded by the turned-over end, then determines the corresponding turning-over end according to the commodity demand information, and in practical application, the user can negotiate the commodity and the quantity required to be turned over based on the turned-over end and the corresponding purchasing end, and determines the corresponding purchasing end to be the turning-over end.

After the corresponding circulation ends and the circulation quantity of all circulation commodities corresponding to each circulation end are determined, circulation interfaces corresponding to each circulation end can be generated according to the circulation quantity, so that the commodities can be circulated in batches according to the circulation interfaces, after the circulation interfaces are obtained, first circulation transcoding of each circulation end based on filling of the circulation interfaces can be received, a transcoding interface is generated, and identity information corresponding to the first circulation transcoding of the corresponding commodity can be changed according to the transcoding interface subsequently, so that the identity information corresponding to the circulation transcoding can correspond to the identity information of an actual user of the commodity.

The specific implementation manner of step S3 based on the above embodiment may be:

s31, analyzing the commodity demand information to obtain demand commodities and purchasing ends corresponding to the demand commodities, taking the corresponding purchasing ends as circulation ends, and counting the quantity of the demand commodities corresponding to the circulation ends to obtain circulation quantity.

In practical application, the purchasing end corresponding to the required commodity can be selected by the user in advance based on the circulated end, and the required commodity and the circulated quantity corresponding to each circulated end can also be negotiated in advance.

S32, if the number of the streams corresponding to the stream ends is 1, a first generation strategy is called to generate a stream interface corresponding to the stream ends, and each stream end receives first stream transcoding based on the stream interface filling to generate a transcoding interface.

If the number of the corresponding circulation ends is 1, it is indicated that only one commodity needs to be circulated by the corresponding circulation end, and in this case, the scheme calls the first generation strategy to generate a circulation interface corresponding to the circulation end, performs independent circulation on the corresponding commodity based on the circulation interface, and receives the first stream transcoding of each circulation end based on the circulation interface to generate a transcoding interface.

Specifically, the specific implementation manner of step S32 may be:

s321, if the number of the circulation ends is 1, the initial interface is called, and equal division is carried out on the initial interface according to a first direction, so that a resale interface and an identity interface are obtained.

The first direction may be a top-to-bottom direction, for example, the initial interface may be divided into a resale interface corresponding to the upper half area and an identity interface corresponding to the lower half area according to the first direction, where the area ratio of the resale interface to the identity interface is 1:1.

S322, a first data filling area is built in the resale interface, a first identity filling area is built in the identity interface, the second identity information is filled in the first identity filling area, a circulation interface corresponding to a corresponding circulation terminal is obtained, and the circulation interface is sent to the corresponding circulation terminal.

The first data pad area may be structured within the resale interface and the first identity pad area may be structured within the identity interface at an intermediate location between the resale interface and the identity interface.

In order to enable the commodity in the resale interface to be corresponding to the second identity information in the follow-up process, the second identity information is required to be filled into the first identity filling area, a circulation interface corresponding to the corresponding circulation terminal is obtained, and then the circulation interface is sent to the corresponding circulation terminal.

S323, receiving the first stream transcoding of the corresponding stream interface based on the stream interface filled in the first data filling area by the stream terminal, and generating a transcoding interface.

After receiving the transfer interface, the transfer terminal can fill the first transfer codes corresponding to the commodities to be transferred into the first data filling area based on the transfer interface to generate a transfer interface, so that the first identity information corresponding to the first transfer codes can be updated into the second identity information according to the transfer interface.

S33, if the number of the streams corresponding to the stream ends is larger than 1, a second generation strategy is called to generate a stream interface corresponding to the stream ends, and each stream end receives first stream transcoding based on the stream interface filling to generate a transcoding interface.

If the number of the corresponding circulation ends is greater than 1, the condition that more than one commodity needs to be circulated by the corresponding circulation ends is indicated, in this case, the second generation strategy is called to generate circulation interfaces corresponding to the circulation ends, the corresponding commodity is circulated in batches based on the circulation interfaces, and likewise, after the circulation interfaces are obtained, each circulation end is also received, based on the first circulation transcoding filled in the circulation interfaces, a transcoding interface is generated.

Specifically, the specific implementation manner of step S33 may be:

s331, if the number of the circulation ends is greater than 1, the initial interface is called, and area division is carried out on the initial interface according to the number of the circulation ends, so that a first transfer interface and a first identity interface corresponding to each circulation end are obtained.

When the circulation number is greater than 1, the method and the system divide the areas of the initial interface according to the circulation number when dividing the resale interface and the identity interface to obtain the first resale interface and the first identity interface, so that more areas can be divided for the first resale interface when the circulation number is more.

In some embodiments, the first transfer interface and the first identity interface described above may be obtained by:

and acquiring the identity number of the identity filling area, and obtaining the dividing duty ratio corresponding to the first transfer interface and the first identity interface according to the ratio of the circulation number to the identity number.

The number of identities may be 1, for example, if the number of streams is 3, the dividing ratio corresponding to the first transfer interface and the first identity interface is 3:1.

For example, when the corresponding division ratio of the first transfer interface to the first identity interface is 3:1, the initial interface may be divided into the first transfer interface and the first identity interface according to the 3:1 ratio from top to bottom.

By the method, the corresponding area division can be performed on the first transfer interface and the first identity interface by combining the circulation quantity, so that more display areas can be divided on the first transfer interface when the circulation quantity is more.

And S332, generating data filling areas corresponding to the required commodities according to the required commodities corresponding to the circulation ends, and arranging the data filling areas in the first resale interface according to an arrangement strategy to obtain second resale interfaces corresponding to the corresponding circulation ends.

It can be understood that when the required commodities in the circulation ends are more, in order to obtain the data corresponding to each required commodity, the invention also generates the data filling area corresponding to each required commodity, and then the data filling area corresponding to each required commodity is arranged correspondingly in the first resale interface according to the arrangement strategy, so as to obtain the second resale interface corresponding to the corresponding circulation end.

In some embodiments, the second resale interface corresponding to the corresponding circulation end may be obtained through the following steps:

a1, calling a preset filling area, equally dividing the preset filling area in a preset direction to obtain an image filling area and a commodity code filling area, calling preset images corresponding to all required commodities, and filling the preset images into the image filling area to obtain a data filling area corresponding to the corresponding required commodity.

The shape of the preset filling area in the scheme is square so as to carry out subsequent parameter adjustment, the preset direction can be the same as the first direction, other preset directions can be set by staff, and the preset image corresponding to the required commodity can be a commodity image of the required commodity.

The preset filling area is divided into an image filling area and a commodity code filling area, so that when the subsequent streaming end uploads the first streaming codes corresponding to the corresponding required commodities, the streaming end can guide the preset image of the required commodities based on the preset image of the required commodities, and the streaming end can upload the first streaming codes corresponding to the corresponding required commodities according to the preset image.

A2, obtaining a quantity adjustment coefficient according to the ratio of the quantity of the circulation to the preset quantity of the circulation, and obtaining the quantity of the display areas based on the upward rounding value of the product of the quantity adjustment coefficient and the preset quantity of the display areas.

The more the circulation quantity is, the more the required commodities are required to be circulated, and the more the data filling areas corresponding to the required commodities are, so that the more the number of display areas of the first display area for displaying the data filling areas can be correspondingly set.

A3, equally dividing the first resale interface in a first direction based on the number of the display areas to obtain a plurality of first display areas, and sequentially arranging and displaying data filling areas corresponding to the required commodities in each first display area according to a second direction and a preset distance to obtain a second resale interface corresponding to the corresponding circulation end.

The second direction may be a direction perpendicular to the first direction, and the second direction may be a left-to-right direction.

Referring to fig. 2, a schematic diagram of a second resale interface including a first display area according to an embodiment of the present invention is provided. As can be seen from fig. 2, when the number of display areas is 3, the first resale interfaces can be equally divided in the first direction according to the area ratio of 1:1:1 to obtain a plurality of first display areas, and then the data filling areas in each first display area are arranged and displayed according to the preset distance according to the second direction to obtain the second resale interfaces corresponding to the corresponding circulation ends.

It should be noted that, the side length of the data filling area is dynamically changed, for example, in the above scheme, the side length of the data filling area cannot be greater than the span length of the first display area in the first direction, and only if the side length of the data filling area is less than the span length of the first display area in the first direction, the data filling area can be arranged and displayed in the first display area.

As can be seen from fig. 3, when the commodity category set is 3 and the ratio of the first number of all required commodities in each commodity category set is 1:2:3, the first resale interface may be divided into regions in the first direction according to the region ratio of 1:2:3 to obtain second display regions corresponding to each commodity category set, and then the data filling regions corresponding to the corresponding commodity category set are arranged and displayed in each second display region according to the second direction to obtain the second resale interface corresponding to the corresponding circulation end.

It should be noted that, in the above-mentioned scheme, the side length of the data filling area is also dynamically changed, that is, the side length of the data filling area cannot be longer than the span length of the corresponding second display area in the first direction, and similarly, only the side length of the data filling area is shorter than the span length of the second display area in the first direction, the data filling area can be displayed in the second display area in an aligned manner.

By the method, the required commodities can be arranged and displayed in groups according to the commodity types of the required commodities, so that the data filling areas corresponding to the required commodities in the same commodity type can be arranged together.

Furthermore, on the basis of the above embodiment, the present invention further includes the following schemes:

obtaining a first number of data filling areas corresponding to each first display area or each second display area, and obtaining a side length adjustment coefficient according to the ratio of the preset number to the first number.

According to the scheme, when the data filling areas are arranged and displayed in the first display area or the second display area, the side length of the data filling areas is adjusted according to the first quantity of the data filling areas corresponding to each first display area or each second display area, so that the side length of each data filling area can be shorter when the data filling areas corresponding to the first display area or the second display area are more, the corresponding data filling areas can be correspondingly reduced and displayed, and vice versa, all the data filling areas can be displayed, and the situation that the data filling areas are too many and are not arranged is reduced.

S333, a second identity filling area is built in the first identity interface, and the second identity information is filled in the second identity filling area, so that a second identity interface corresponding to the corresponding circulation terminal is obtained.

Similarly, in order to enable the commodity in the second resale interface to correspond to the second identity information later, the scheme contemplates a second identity filling area in the first identity interface, and then fills the second identity information into the second identity filling area to obtain a second identity interface corresponding to the corresponding circulation end.

S334, generating a circulation interface corresponding to the corresponding circulation end according to the second resale interface and the second identity interface, sending the circulation interface to the corresponding circulation end, receiving the first stream transcoding of each circulation end based on the circulation interface filling, and generating a transcoding interface.

When the circulation terminal uploads the commodity scanning code based on the data filling area in the circulation interface, the circulation terminal can upload the commodity scanning code of the commodity in corresponding requirement through the commodity code filling area in the data filling area.

When the first identity information corresponding to the corresponding data filling area is acquired, the first identity information of the first stream transcoding corresponding to the preset image can be acquired according to the preset image in the corresponding data filling area.

If the third identity information is inconsistent with the first identity information, it indicates that the commodity corresponding to the commodity scanning code may not be held by the corresponding transfer terminal, and the identity information of the commodity is not corresponding, so that identity error information can be generated and sent to the corresponding transfer terminal, and the corresponding transfer terminal can perform identity determination.

And S3342, if the third identity information is consistent with the first identity information, generating identity verification information, and acquiring a commodity image corresponding to the commodity scanning code based on the identity verification information.

S3345, updating the circulation interface according to the commodity corresponding area to obtain a transcoding interface.

By the method, not only can the transfer terminal provide guidance for uploading the commodity scanning code, but also the transfer data of the transferred demand commodity can be corresponding to the corresponding second identity information of the transferred terminal through the transcoding interface, so that the first identity information corresponding to the first transfer code can be updated to the second identity information according to the transcoding interface.

S4, converting the first identity information of the corresponding first stream codes into second identity information according to the transcoding interface, generating corresponding second stream codes, and storing the stream terminal information and the second stream codes into corresponding commodity nodes.

After the transcoding interface is obtained, the first identity information of the corresponding first stream transcoding in the transcoding interface can be converted into the second identity information, the second stream transcoding is generated, and then the second stream transcoding is stored in the corresponding commodity node.

By the method, the identity information corresponding to each commodity can be updated in time according to the stream transfer information of each commodity, so that the identity information corresponding to the stream transfer code of each commodity can correspond to the identity information of the actual user of the commodity.

After receiving the traceability information of the verification terminal for the first stream transcoding or the second stream transcoding, the scheme can acquire the first identity information corresponding to the first stream transcoding or the second identity information corresponding to the second stream transcoding, and when the verification identity information input by the verification terminal is consistent with the first identity information or the second identity information, the identity information of the verification terminal is consistent with the corresponding identity information corresponding to the first stream transcoding or the second stream transcoding, and under the condition, the scheme can be used for transmitting the matching success information to the verification terminal.

If the verification identity information input by the verification terminal is inconsistent with the first identity information or the second identity information, the identity information of the verification terminal and the corresponding identity information of the first stream transcoding or the second stream transcoding are inconsistent, and in this case, the scheme does not generate successful matching information and sends the successful matching information to the verification terminal, and the corresponding verification terminal cannot inquire the traceability information of the first stream transcoding or the second stream transcoding.

By the method, the identity information corresponding to the first stream transcoding or the second stream transcoding can be unique, so that the counterfeiting rate of the first stream transcoding or the second stream transcoding can be reduced.
