In general, courier companies in many countries, including Korea, choose a service that delivers items ordered by customers directly to their homes.

However, this method can lead to crimes such as stealing packages left in front of homes and leakage of personal information attached to packages. This causes consumers to feel anxious that their products and personal information are not kept safe.

To solve this problem, unmanned delivery systems consisting of electronic door locks or kiosk methods are being introduced.

In the case of the electronic key door lock method, anyone, not just the delivery driver, can put items in it, so over time, the problem of the delivery box being used for personal luggage storage arises. In addition, there is a problem that it is impossible to verify the identity of the courier sender and courier recipient, and many errors occur when sending password text messages.

Meanwhile, in the case of the kiosk method, although it is not used for storing personal luggage, there is a problem that a separate ID card is required when storing parcels for identity verification or a cumbersome registration process must be completed.

In particular, in the case of the kiosk method, when a public key is used in the process of identity verification, it is not known whether the public key is an authenticated public key, and the problem of personal information leakage still exists because personal information is included in the database.

Therefore, a method is needed to not only safely store personal information, but also to ensure that only users who have been authenticated by a certification agency can deliver or receive goods.

Accordingly, the detailed description that follows is not intended to be taken in a limiting sense, and the scope of the invention is limited only by the appended claims, together with all equivalents to what those claims assert, if properly described. Similar reference numbers in the drawings refer to identical or similar functions across various aspects.

The components according to the present invention are components defined by functional division rather than physical division, and can be defined by the functions each performs. Each component may be implemented as hardware or program code and processing units that perform each function, and the functions of two or more components may be included and implemented in one component. Therefore, the names given to the components in the following embodiments are not intended to physically distinguish each component, but are given to suggest the representative function performed by each component, and the names of the components are used to describe the present invention. It should be noted that the technical idea is not limited.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

Figure 1 is a diagram for explaining the configuration of a delivery system 10 according to an embodiment of the present invention.

The delivery system 10 (hereinafter referred to as system) according to this embodiment can deliver goods based on a blockchain network using DID (Decentralized ID).

Here, blockchain is one of the core technologies of ICT (Information & Communication Technology) and is attracting attention as a next-generation network technology. Blockchain is a type of distributed database that has the characteristic that all nodes are equal because there is no central server.

These blockchains are divided into public blockchains, where anyone can freely participate in the network, and private blockchains, where only authorized people can participate in the network. Depending on the characteristics of the blockchain, PoW (Proof of Work) and PoS (Proof of Stake) Blocks are created using various consensus algorithms such as , or PBFT (Practical Byzantine Fault Tolerance).

In a blockchain, data is called a “block,” and each block is linked and stored in a chain through a hash value. Because blockchain participants verify and store all transaction details, even if a malicious user modifies the transaction details, the ledger of all participants must be modified to modify one transaction.

Accordingly, blockchain has the characteristic that the reliability of the data is guaranteed because the data is verified through the agreement of participants rather than a third party, and integrity is guaranteed because everyone has the same information.

The system 10 according to this embodiment can solve security problems through blockchain and authenticate identity using blockchain-based DID.

DID, a distributed identity, refers to a unique identifier that can prove one's identity by CRUD (Create, Read, Update, Delete) information that can identify an individual without a central authority. DID is a key value that serves as a pointer to the DID document of a blockchain transaction. In particular, DID is an identifier generated based on the user's public key.

Meanwhile, a DID document refers to a set of data necessary for an individual to authenticate himself and prove his association with the DID. In other words, the DID document is the subject of DID's CRUD performance, and is information necessary for verification when using the DID service. For example, the data set includes properties such as public key, authentication method, and digital signature value.

Accordingly, the relationship between the DID and the DID document described above is to search the DID in the blockchain and create a DID document based on the transaction contents, and the method of reading the DID document based on the DID may be different for each blockchain.

The system 10 according to this embodiment not only allows only users whose identity authentication has been completed based on blockchain using the above-described DID to deliver or receive goods, but also does not store personal information in the database, thereby providing personal information It is designed to protect.

To this end, the system 10 may include a purchaser terminal 100, a shopping mall server 200, a delivery server 300, a delivery station 400, and a deliverer terminal 500. And the buyer terminal 100, shopping mall server 200, delivery server 300, delivery station 400, and delivery terminal 500 have software (application) for performing the product delivery method installed and executed. You can.

Accordingly, the buyer terminal 100, shopping mall server 200, delivery server 300, delivery station 400, and deliverer terminal 500 can be controlled by software (application) for performing the product delivery method.

Here, the buyer terminal 100, shopping mall server 200, delivery server 300, delivery station 400, and delivery terminal 500 may be mobile or fixed, and may be a server or an engine. It may be in the form of a device, apparatus, terminal, UE (user equipment), MS (mobile station), wireless device, handheld device, etc. You can.

And the buyer terminal 100, shopping mall server 200, delivery server 300, delivery station 400, and delivery terminal 500 run various software based on an operating system (OS), that is, a system. It can be produced. The operating system is a system program that allows software to use the hardware of the device, and includes mobile computer operating systems such as Android OS, iOS, Windows Mobile OS, Bada OS, Symbian OS, Blackberry OS, Windows series, Linux series, Unix series, etc. It can include all computer operating systems such as MAC, AIX, and HP-UX.

First, the buyer terminal 100 may be a device carried by the buyer who purchases the product.

And the buyer terminal 100 can open the box of the delivery station 400 through communication with the delivery station 400. Accordingly, the buyer terminal 100 can receive goods stored at the delivery station 400, or store the goods in order to exchange or return the received goods.

Additionally, the purchaser terminal 100 can generate a purchase VP (Verifiable Presentation) that can authenticate that the user is a user who can open the box of the delivery station 400.

Figure 2 is a diagram for explaining a purchase VP created in the buyer terminal 100 according to an embodiment of the present invention.

The purchase VP created by the buyer terminal 100 may include metadata and buyer VC.

Metadata may include purchase information related to purchase and receipt of goods. As shown in FIG. 2, the purchase information is information related to the product purchased by the buyer, and may include, for example, the product number, whether or not delivery charges are collected, and special information related to delivery.

Meanwhile, the buyer VC may include the buyer's name, phone number, and the address of the delivery address or delivery station where the product will be delivered.

These buyer VCs are credential information used to authenticate identity using DID. Specifically, VC is a set of data that specifies all information that can represent an arbitrary user as ID attributes, and may refer to verifiable credential information issued by a public certification authority.

And the buyer terminal 100 can create a purchase VP including such metadata and buyer VC. Here, the purchase VP may be composed of a set of verifiable ID data including multiple VCs.

And the buyer terminal 100 can transmit the generated purchase VP to the shopping mall server 200 and have the purchase VP stored on the blockchain network.

Accordingly, the shopping mall server 200, which verifies such purchase VP, can check the ID attribute and user information of the VP and then perform verification work on the organization that issued each ID attribute and the user who submitted the VP.

And when the ordered product is stored in the delivery station 400, the buyer terminal 100 can receive a product receipt notification from the delivery station 400.

Additionally, after receiving the product receipt notification, the buyer terminal 100 transmits the buyer DID to the delivery station 400 to authenticate that he or she is the buyer who purchased the product, thereby allowing the box at the delivery station 400 to be opened. .

Specifically, the buyer terminal 100 can scan the QR code output from the delivery station 400 and input the buyer DID into the URL (Uniform Resource Locator) of the delivery station 400.

Meanwhile, the shopping mall server 200 may receive the purchase VP from the buyer terminal 100 and perform authentication of the purchase VP.

More specifically, the shopping mall server 200 can transmit the buyer DID corresponding to the buyer VC included in the purchase VP to the blockchain network.

And the shopping mall server 200 can authenticate the purchasing VP based on the buyer DID.

Accordingly, the shopping mall server 200 can transmit a delivery request including the purchase VP to the delivery server 300 when the purchase VP is authenticated.

And, when the goods stored in the delivery station 400 are taken out by the buyer, the shopping mall server 200 can receive a notification of completion of goods receipt from the delivery server 300.

Additionally, the shopping mall server 200 may set a return deadline based on the point in time when a notification of product receipt completion is received and store the purchase VP until the return deadline.

Accordingly, the shopping mall server 200 can authenticate buyers and process services using only the DID without storing authentication-related data containing personal information in the database, thereby safely protecting personal information.

Meanwhile, the delivery server 300 may receive a delivery request from the shopping mall server 200 and generate waybill information for delivery of the product.

And the delivery server 300 can determine the deliverer of the product. To this end, the delivery server 300 can obtain information in advance regarding the deliverer who can deliver the product.

Additionally, the delivery server 300 may create a unique delivery VP corresponding to the delivered product.

Figure 3 is a diagram for explaining a delivery VP created in the delivery server 300 according to an embodiment of the present invention.

Referring to FIG. 3, the delivery VP created in the delivery server 300 may include metadata, buyer VC, and deliverer VC.

Here, the deliverer VC may include the name and phone number of the deliverer.

And the delivery server 300 according to this embodiment can deliver the generated delivery VP to the delivery station 400 that stores the corresponding item and the delivery terminal 500 possessed by the determined delivery person.

Additionally, when the delivery of the product from the delivery station 400 is completed, the delivery server 300 may receive a product receipt completion notification from the delivery station 400 and transmit this product receipt completion notification to the shopping mall server 200.

And the delivery server 300 according to this embodiment can delete the delivery VP according to predetermined conditions.

For example, when the buyer completes receipt of the product and receives a product receipt completion notification from the delivery station 400 or the buyer terminal 100, the delivery server 300 may delete the delivery VP corresponding to the product.

As another example, the delivery server 300 may delete the delivery VP when the validity period included in the delivery VP has elapsed after the goods receipt notification notification is transmitted to the buyer terminal 100.

More specifically, as shown in FIG. 3, metadata included in the delivery VP according to this embodiment may include the expiration date along with the above-described purchase information. This validity period is a fixed period, for example, 7 days, and can be set by adding 7 days from the time the delivery VP is created. As another example, the validity period can be flexibly changed based on the time when the delivery VP is created. For example, if the delivery VP is created at a time when delivery volume is concentrated, such as during a holiday, or when there may be a shortage of delivery personnel, such as during a vacation period, an additional period (such as 5 days) is added to the fixed period (for example, 10 days). You can set the validity period.

This validity period is a period of time plus a predetermined period from the time the delivery server 300 creates the delivery VP, and may mean a period for storing the delivery VP.

Meanwhile, the delivery station 400 may include a box for storing goods.

Figure 4 is an exemplary diagram for explaining the process of storing or removing goods from the delivery station 400 according to an embodiment of the present invention.

As shown in FIG. 4, the delivery station 400 may be provided in the form of a kiosk that includes a display and controls boxes.

Additionally, the delivery station 400 can be installed in public institutions such as unmanned convenience stores, police stations equipped with CCTV, and neighborhood offices, or in public parking lots.

This delivery station 400 may receive the delivery VP from the delivery server 300 and authenticate the deliverer VC or buyer VC based on the delivery VP.

Therefore, the delivery station 400 can open the box and allow the goods to be stored or taken out according to the result of authenticating the deliverer VC or the purchaser VC.

And the delivery station 400 can output a QR code on the display that allows access to a URL where the delivery VP can be entered.

Accordingly, the buyer terminal 100 or the deliverer terminal 500 can scan the QR code displayed on the display of the delivery station 400 and input the buyer DID into the URL of the delivery station 400.

At this time, the delivery station 400 can perform the VC authentication procedure by including the VC authentication URL in the QR code and using a decryption method using an asymmetric key.

That is, the delivery station 400 may include a URL that allows input of at least one of the buyer DID and the deliverer DID corresponding to the buyer VC and the deliverer VC in the QR code.

Therefore, the buyer terminal 100 or the deliverer terminal 500 can scan the QR code and input the buyer DID or the deliverer DID.

If the deliverer terminal 500 inputs the deliverer DID to bring an item into a box, the delivery station 400 can authenticate the delivery VP using the deliverer DID.

Accordingly, the delivery station 400 can open the box when the delivery VP's authentication is completed.

When the loading of the goods into the box is completed, the delivery station 400 may generate a goods receipt guidance notification that includes the box number and location information of the delivery station 400 where the goods are stored.

Additionally, the delivery station 400 may transmit a product receipt guidance notification generated to the buyer terminal 100 based on the buyer VC included in the delivery VP.

Meanwhile, when the buyer terminal 100 inputs the buyer DID to take the product out of the box, the delivery station 400 can authenticate the delivery VP.

Accordingly, the delivery station 400 can open the box when the delivery VP's authentication is completed.

As described above, in this embodiment, both the buyer terminal 100 and the deliverer terminal 500 can use only one delivery VP corresponding to the product for identity authentication required when delivering or receiving the product.

Additionally, the delivery station 400 may open the box and generate a product receipt completion notification when the product is taken out of the box.

Additionally, the delivery station 400 may deliver a notification of completion of item receipt to the URL of the delivery server 300 according to the waybill information included in the delivery VP. Here, the product receipt completion notification may be generated and delivered from the buyer terminal 100 rather than the delivery station 400, if necessary.

Meanwhile, the deliverer terminal 500 may be a terminal possessed by the deliverer determined by the delivery server 300 to deliver the goods to the delivery station 400.

The deliverer terminal 500 may transmit the deliverer DID corresponding to the deliverer VC and the delivery VP received from the delivery server 300 to the delivery station 400 in order to open the box.

Through this, the system 10 according to this embodiment not only integrates all authentication tasks by using DID authentication in the overall product delivery process from purchase to receipt of the product, but also protects personal information because it does not verify personal information. It can provide beneficial effects.

Meanwhile, Figure 5 is a flowchart for explaining a method for delivering goods according to an embodiment of the present invention. The method for delivering goods according to an embodiment of the present invention is carried out on substantially the same configuration as the system 10 shown in Figure 1. Therefore, the same reference numerals will be assigned to the same components as those of the system 10 of FIG. 1, and repeated descriptions will be omitted.
