As shown in FIG. 1 , the system for managing the distribution history of goods according to an embodiment of the present invention includes an authorized tagging station 110 , a goods moving means 120 , an intermediate distribution site 130 , and a final destination.

Referring to FIG. 1 , the authorized tagging station 110 is an authorized place for registering an item that is the first distribution history management target. It may include a target article 112 , a tag device 114 , and a first tag reader 116 . When the target article 112 is a fish, the article 112 may arrive at the authorized tagging station 110 through a fishing vessel, a farm, and a deep-sea fishing vessel. In this case, the authorized tagging station 110 may be a place near the origin. In the case of other goods such as medicines, they can be supplied from production sites such as factories. In the present specification, it will be apparent to those skilled in the art that the part described by assuming a fish as the target article 112 can be replaced with other articles.

The authorized tagging station 110 is equipped with the above devices and has a first tag reader 116 with a function to register in the block chain 150 or a place equipped with a smart device that interworks with the first tag reader 116 to be. Here, tasks such as tagging and authentication of the article 112 and registration of related information are performed.

The manager of the authorized tagging station 110 , which is a place where the target article 112 arrives, fills the target article 112 with the tagging device 114 . "Filling" means physically attaching the tag device 114 to a part of the article 112 in a bound state. That is, the tag device 114 is formed in an annular shape, and the administrator of the authorized tagging station 110 sews the annular ring to one area of the article 112 to make a binding state. Since the tag device 114 has an annular shape and is a medium through which electricity is transmitted, it is possible to detect a corresponding action when an unexpected physical pressure such as cutting is applied. The tag device 114 may be referred to as a smart chain, an electric ring, or the like.

When the tagging is completed, the first tag reader 116 or the smart device interworking with the first tag reader 116 registers the target article 112 in the block chain 150 . Hereinafter, a portion expressed as “tag reader” may be used as a term referring to equipment including at least one of a function of a tag reader and a function of a smart phone. This may be a portable terminal. The first tag reader 116 may be an authenticated registration device. The first tag reader 116 may be capable of wireless communication and image capturing. The first tag reader 116 acquires information on the distribution history management target article 112 by photographing the tag device 114 or by receiving information from the tag device 114 through wireless communication, and uses the obtained information. It is registered in the block chain 150 . In this case, the tag device 114 itself can digitally sign. The electronic signature may be automatically made using the asymmetric key stored in the tag device 114 . In addition, the unique identification number assigned to the tag device 114 may be used as the unique identification information of the article 112 . Accordingly, the target article 112 can be registered in the block chain at the same time as tagging is completed without the manual operation of the administrator of the authorized tagging station 110 . That is, the tag device 114 electrically recognizes an operation in which the two ends of the chain are connected by passing through the article 112 and automatically inserts the article ( 112 may be requested to the first tag reader 116 to register.

In this case, the first tag reader 116 may automatically upload the location information and the registration time information of the authorized tagging station 110 that is registered using GPS information. Moreover, when registering the article 112 , the administrator may upload various information related to the article to the block chain 150 . For example, information such as the size of the article 112 , the fish species, the current state, etc. may be uploaded to the blockchain 150 together. In addition, a tagging image of the article 112 and image information describing details of the registration process may be registered together. Thereafter, storage, upload, and update of the target article 112 to the block chain 150 are performed on the unique identification number of the pre-registered article 112 . That is, after registration, a book related to a unique identification number can be continuously created on the block chain 150 .

The moving means 120 may be transportation equipment such as a vehicle, a ship, or an airplane, and may include a wireless repeater 122 . In the moving means 120 , the wireless repeater 122 may periodically or aperiodically receive status information of the article 112 from the tag device 114 filled in the target article 112 . That is, the wireless repeater may be wirelessly connected to the tag device 114 and connected to the block chain 150 through the Internet or other communication networks. That is, through this, as a result, the information from the tag device 114 is relayed to the block chain 150 . In the case of fish, using a sensor module (not shown) mounted on the tag device 114 , information related to the temperature, humidity, and distribution quality of the article 112 during movement may be transmitted to the repeater 122 , and the repeater 122 . ) stores it in the block chain 150 . In this case, time information of the relay point and GPS-based location information may be stored together. In addition, the wireless repeater 122 may also upload the identification information of the moving means to the block chain 150 together.

The intermediate distribution site 130 may be a place through which the target article 112 passes before arriving at the final destination 140 through the moving means 120 from the authorized tagging station 110 or another intermediate distribution site. It may not exist. The manager of the intermediate distribution center 130 may use the second tag reader 132 to update information related to the target article 112 in the block chain 150 . For example, the information related to the target article 112 includes information related to processing in the intermediate distribution site (data in the form of images or text), registration time in the intermediate distribution site, location information, and the like.

The article 112 may arrive at the final destination 140 by using the moving means 120 again through the intermediate distribution center 130 . The final destination 140 may be equipped with a third tag reader 142 . The final destination 140 may be a fish retailer or related restaurant. When the item 112 arrives, the person in charge of the restaurant uses wireless communication between the tag device 114 mounted on the item 112 and the third tag reader 142 to receive information from the initial authentication of the item 112 to the information in the distribution process. can be confirmed by obtaining from the blockchain 150. In some cases, a method such as QR code parsing may be used. For example, the third tag reader 142 recognizes the identification information of the corresponding article 112 through image information obtained by photographing the tag device 114, and requests it to the block chain 150 for the corresponding article ( 112) and related information can be obtained. The person in charge of the final destination 140 uses the registered text information and/or image information to obtain information such as the authenticity authentication process at the origin of the goods 112, the temperature in the distribution process, whether theft and damage are attempted, and the movement route. can figure out In addition, it is possible to ensure the stability in the security of information by using the block chain.

According to an embodiment of the present invention, the first, second, and third tag readers 116, 132, and 142 may be smart devices such as PCs, smart phones, and laptops, and for information registration and information confirmation of the block chain The application (APP) may be a downloaded device. The application may be software distributed and managed from a server providing a service for managing distribution history of the present invention. The first, second, and third tag readers 116 , 132 , and 142 may be the same device or different devices. Basically, it is desirable to have different equipment owned by different users in different places.

2 is a flowchart specifically illustrating a method for managing a distribution history of an article according to an embodiment of the present invention.

Referring to FIG. 2 , when an item to be distributed 112 arrives at the authorized tagging station 110 which is the first place, the manager of the station mounts a tag device 114 capable of wireless communication on the item 112 ( S210). Then, the article 112 is registered in the block chain 150 using the first tag reader 116 capable of wireless communication with the tag device 114 (S220). At this time, when a smart chain, which is a tag device 114 with a unique number assigned to the fish, is mounted on the fish to generate a unique identification number of the fish as shown in FIG. The unique number given in (114) becomes the unique identification number of the fish. Registration can be authenticated by the administrator's digital signature. In addition, the asymmetric key stored in the smart chain which is the tag device 114 can be utilized, and it is possible to prevent fraud that may occur in the registration process using CCTV and surrounding devices.

The authorized tagging station 110 is a production site of the goods 112. For example, in the case of livestock products, it may be a shipment site of a local livestock product primary processing plant, and in the case of aquatic products, a vessel or a vessel that catches catches. It may be a warehouse or a shipping place where seafood is first received from

When registration is completed, the article 112 is transported through the moving means 120 (S230). At this time, by using the wireless repeater 122 disposed in the moving means 120, it is possible to update the state information and location information of the item in the block chain (S240). The state information may include information such as temperature, humidity, pressure, light quantity, power, etc. of the item, and location and time information when the corresponding state information is updated may be stored together in the block chain 150 .

In the block chain update, the wireless repeater receives the status information of the article from the tag using short-distance communication, and the wireless repeater provides the received state information of the article to the block chain.

It is determined whether there is an intermediate distribution site 130 as the second place (S250), and if there is no intermediate distribution site 130, the tag device 114 attached to the article 112 at the final destination 140 which is the third place. Information in the distribution process is acquired through information transmission/reception between the and the third tag reader 142 (S260). Through this, it is possible to verify the authenticity of the corresponding article 112 .

If there is an intermediate distribution center 130 that is a second place, the information related to distribution in the intermediate distribution area 130 is updated in the block chain 150 using the second tag reader 132 existing in the distribution area. And (S255), the goods 112 through the moving means 120 again is transferred to the next intermediate distribution or final destination (140).

The tag device 114 communicates with the article 112 through the wireless repeater 122 so that the state information in the distribution process of the article 112 out of the intermediate distribution center 130 is updated in the block chain 150 . The method may further include providing relevant status information. The wireless repeater is a repeater that wirelessly communicates with the tag device 114 .

The communication module 620 is electrically connected to the electric ring module and the sensing module, and is a means of wirelessly communicating with the tag reader, and may be implemented as a communication processor chip and/or antenna for performing short-distance and/or broadband communication. have. The communication module 620 may directly perform short-range communication such as Bluetooth, ZigBee, and Wi-Fi, as well as IoT-based communication such as LoRa, and broadband communication. In addition, information can be provided to the block chain by indirectly connecting to the communication network using a repeater.

The battery 630 is very small and provides power required for the tag device.

The sensing module 640 senses the state of the article and generates state information. As described above, the sensing module 640 may include at least one of a temperature sensor, a pressure sensor, an illuminance sensor, a humidity sensor, a light quantity sensor, and a power sensor. The sensing module 640 performs sensing according to a predetermined period.

The memory 650 may store instructions related to the operation of the controller 610 and may store tag device-specific information such as tag identification information. In addition, a very small amount of sensing information may also be stored.

In some cases, it is connected to a separate item information input device (information input device such as a smart phone) to receive detailed information of the item from the device and store it in the memory 650. You can also have it registered. For example, in the case of articles such as pharmaceuticals, information such as the date of manufacture, product description, country of origin, price, sending time, etc. may be received from the article information input device and stored in the memory 650 .

The encryption key module 660 stores the PKI system, and may perform a digital signature operation when authenticating and registering an article.

The electric ring module 670 is a ring that is energized as a chain-shaped annular structure that is mounted in a state of being bound through an object and is energized. The chain of the electric ring module 670 generates a cutting warning signal by immediately or immediately detecting a cutting attempt when a microcurrent flows through the chain at all times or periodically. The generated signal is uploaded to the blockchain directly and/or indirectly through a relay device such as a wireless repeater. And when the ring-shaped ring is cut, the communication module of the tag notifies the cut-off to the wireless repeater using short-distance communication, and the registration information of the article is deleted from the block chain.

According to another embodiment of the present invention, the device may further include a GPS module (not shown), and in conjunction with the communication module 620, the location information of the device is periodically transmitted to the block chain using short-distance communication or broadband communication. (or aperiodically).

FIG. 8 is a diagram illustrating an actual implementation of the tag device of FIG. 7 .

Referring to FIG. 8 , the smart chain, which is a tag device, is composed of a processor chip and an anti-forgery chain (electric ring module). In particular, the communication module of the processor chip may have a built-in antenna for wireless communication as an ultra-small, ultra-light and ultra-low power communication module. It can be manufactured as a communication module with a diameter of 1 cm using LTCC (Low Temperature Co-fired Ceramic) microprocessing technology. In this way, it is possible to prevent deterioration in function due to miniaturization.

According to an embodiment of the present invention, the tag device may have strength enough to withstand the gravity of 500 kg. In addition, since there is a wire inside the electric ring, that is, the chain, when the chain is cut, it recognizes the cut and loses the unique number of the item in the block chain, thereby preventing counterfeiting of the item's unique number.

According to an embodiment of the present invention, the tag device may have a waterproof function.

Although described above with reference to the drawings and embodiments, it does not mean that the scope of protection of the present invention is limited by the drawings or embodiments, and those skilled in the art can appreciate the spirit of the present invention described in the claims below. And it will be understood that various modifications and changes can be made without departing from the scope of the present invention.
