The plurality of computer devices may be a plurality of node devices belonging to the same organization, or may be a plurality of node devices belonging to different organizations. For example, the plurality of computer devices may each belong to a garbage disposal facility, each department in the garbage disposal facility corresponds to at least one computer device in the garbage disposal facility, or at least one computer device in the plurality of computer devices is a user device, at least one computer device belongs to a garbage disposal facility, at least one computer device belongs to an environmental protection regulatory agency, and of course, there may be at least one computer device belonging to other facilities, such as other social regulatory agencies, and the like.

The plurality of computer devices may be servers or terminals, which is not particularly limited in the embodiment of the present application.

In order to facilitate understanding of the technical process of the embodiments of the present application, some terms related to the embodiments of the present application are explained below:

blockchain (Block chain): is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like. The blockchain is essentially a de-centralized database, which is a series of data blocks generated by cryptographic association, each data block containing information of a network transaction for verifying the validity (anti-counterfeiting) of the information and generating a next block, each block containing a time stamp and a link to the previous block. In a narrow sense, a blockchain is a chain data structure that combines blocks of data in a sequential manner in time order, and cryptographically guaranteed, non-tamperable and non-counterfeitable, distributed ledgers, i.e., the data in the blockchain will be irreversible once recorded.

Consensus mechanism (Consensus mechanism): is a mathematical algorithm for realizing trust establishment and rights acquisition among different nodes in a block chain system. In a blockchain system, the verification and confirmation of a transaction can be completed in a short time through voting of special nodes, and if a plurality of nodes with irrelevant interests can reach consensus for one transaction, all the nodes in the system can be considered to reach consensus for the same.

Smart contract: is a computer protocol that aims to propagate, verify or execute contracts in an informative manner. Each node in the blockchain system can operate the data stored on the chain according to the contract program automatically executed by the specific condition, and is an important way for users to interact with the blockchain and realize business logic by using the blockchain. The purpose of smart contracts is to provide a secure method over traditional contracts and reduce other transaction costs associated with the contracts, which allows trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.

Public Key (Public Key) and Private Key (Private Key): is a key pair (i.e., a public key and a private key) obtained by an algorithm, the public key being the public part of the key pair and the private key being the non-public part. Public keys are commonly used to encrypt data, verify digital signatures, and the like. By means of this algorithm it is ensured that the resulting key pair is unique, and when using this key pair, if one of the keys is used to encrypt a piece of data, it must be decrypted with the other key, e.g. the public key is used to encrypt the data, and if the private key is used, it must be decrypted with the public key, otherwise the decryption will not succeed.

Fig. 2 is a flowchart of a garbage collection method based on a blockchain, which is provided in an embodiment of the present application, and the garbage collection method based on the blockchain may be applied to any node device in the blockchain system, referring to fig. 2, and the embodiment may specifically include the following steps:

201. the first node device generates a user identification of a target user on a blockchain of the blockchain system based on a registration behavior of the target user.

The first node device may be a client device used by the target user, or may be a server corresponding to the client device, where the client device used by the target user may be installed and run with a target application program, where the target application program may provide a real name registration function.

Taking the first node device as the server corresponding to the client device as an example, in the embodiment of the present application, the client device may display a registration page of the target application program, where the registration page may include an information input area and a first confirmation control, when the client device detects a triggering operation of the target user on the first confirmation control, input information in the information input area may be acquired, the input information and a registration request are sent to the first node device, the first node device may generate, based on the registration request and the input information, a user identifier of the target user and a public key and a private key of the target user corresponding to the user identifier, where the user identifier may be used to uniquely identify a user, and the first node device may store the user identifier of the target user and the public key onto a blockchain of the blockchain system, and the private key may be stored by the target user. The triggering operation may be a clicking operation, a long-press operation, or the like, which is not specifically limited in the embodiment of the present application.

In one possible implementation, the first node device will store the public key and user identification of the target user on the blockchain based on a consensus mechanism. Specifically, for each node in the blockchain system, the node identifier corresponding to the node is provided, and each node device in the blockchain system can store the node identifiers of other node devices in the blockchain system, so that the generated block is broadcast to other node devices in the blockchain system according to the node identifiers of the other node devices, and the other node devices can realize consensus on the block. Each node device may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol, protocol of interconnection between networks) address, and any other information that can be used to identify the node, and the IP address is only illustrated in table 1.

TABLE 1

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

Each node device in a blockchain system may store one and the same blockchain. Fig. 3 is a schematic block chain structure diagram provided in an embodiment of the present application, referring to fig. 3, the block chain is composed of a plurality of blocks, an initiation block 301 includes a block header and a block body, the block header stores an input information feature value, a version number, a timestamp and a difficulty value, and the block body stores input information; the next block 302 of the starting block takes the starting block 301 as a father block, the next block 302 also comprises a block header and a block main body, the block header stores the input information characteristic value of the current block 303, the block header characteristic value of the father block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the father block, and the safety of the input information in the block is ensured.

When each block in the blockchain is generated, the node equipment where the blockchain is located checks the input information when receiving the input information, in the embodiment of the application, the input information can be the user identifier and the public key of the target user, after the node equipment checks the input information, the input information is stored in the memory pool, the hash tree used for recording the input information is updated, then the update timestamp is updated to the time of receiving the input information, different random numbers are tried, and characteristic value calculation is carried out for a plurality of times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_merkle_rool+ntime+nbits+x))<TARGET

wherein SHA256 is a eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.

Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the node where the blockchain is located sends the newly generated current block to other nodes in the blockchain system where the node is located according to the node identification of other nodes in the blockchain system, the other nodes carry out consensus on the newly generated current block, and the current block can be added into the blockchain after the current block passes the consensus, if the current block does not pass the consensus, the block uplink operation can be omitted. Referring to fig. 4, fig. 4 is a schematic diagram of a user data structure on a blockchain provided by an embodiment of the present application, where the user identification and public key of the target user may be stored in the manner shown in area 401.

It should be noted that, the foregoing description of storing the user identifier and the public key of the target user in the blockchain is merely an exemplary description of a storage manner, and the embodiment of the present application does not limit what storage manner is specifically adopted.

202. The second node equipment acquires the user identification of the target user based on the garbage throwing instruction of the target user.

The second node device may be a node device corresponding to an intelligent dustbin, where the intelligent dustbin may receive a garbage throwing instruction, identify a target user triggering the instruction, and execute a subsequent garbage recycling step based on the instruction.

In the embodiment of the present application, the process of obtaining the user identifier by the second node device may include any one of the following implementation manners:

in a first implementation manner, the second node device collects a user image of the target user, and determines a user identifier of the target user based on an image recognition technology. In one possible implementation, the process may specifically include the steps of:

step one, when a garbage throwing instruction of the target user is received, the second node equipment can acquire a user image of the target user.

In the embodiment of the present application, the triggering manner of the garbage throwing instruction may include any one of the following possible implementation manners:

(1) The garbage launch instruction may be triggered by a click operation on a target control on the intelligent garbage can. In one possible implementation manner, the intelligent dustbin may be provided with a target control, and the target control may provide a function of starting a garbage throwing process, and of course, the intelligent dustbin may also be provided with an image acquisition function. The target user can trigger the garbage throwing instruction by clicking the target control, so that the target garbage can executes the subsequent image acquisition step.

(2) The garbage can release instruction may be triggered by a cover opening operation of the intelligent dustbin. The intelligent dustbin can detect the operation of a target user, and when the opening operation of the target user is detected, the garbage throwing instruction can be triggered.

After the intelligent dustbin receives the garbage throwing instruction, a user image of the target user can be collected, wherein the user image can be a face image of the target user. The smart dustbin may send the user image to the second node device.

And step two, the second node equipment identifies the user image, and determines the user identification of the target user based on the identification result.

In one possible implementation, the second node device may apply face recognition techniques to identify the user image to determine the user identification of the target user. Specifically, first, the second node device may perform face detection on the user image based on structural distribution characteristics of the face, determine whether the face of the target user exists in the user image, and if the face exists, further give key information of the face, such as a position, a size, and position information of each main facial organ of the face; then, the second node device can calculate a plurality of geometric feature quantities according to the information of the five sense organs in the key information of the face, and construct feature data capable of describing the facial features of the target user based on the geometric feature quantities; and finally, searching and matching the feature data with a feature template stored in the data, obtaining a feature template with highest similarity with the feature data, and outputting a user identifier corresponding to the feature template as the user identifier of the target user. It should be noted that the above description of the face recognition method is merely an exemplary description of one face recognition method, and the embodiment of the present application does not limit what face recognition method is specifically adopted.

In a second implementation manner, the second node device obtains the user identifier input by the target user.

In one possible implementation, the smart trash can may be configured with an information input area that may be provided by a user with user identification input functionality. The intelligent dustbin can detect information input operation of a target user in the information input area, and when the information input operation is finished, input information of the target user is obtained and used as a user identification of the target user.

In the process, the user identification of the garbage throwing user is obtained, so that the garbage throwing condition of each user can be accurately recorded, and garbage tracing can be conveniently carried out in the subsequent garbage recycling process. Of course, the description of the method for obtaining the user identifier in the above process is only an exemplary description, the second node device may also obtain the user identifier of the target user based on the biometric identification technologies such as fingerprint identification and iris identification, and may also obtain the user identifier of the target user by scanning a two-dimensional code, which user identifier obtaining method is specifically adopted in the embodiment of the present application is not limited.

203. And the second node equipment acquires the throwing type of the garbage bag and generates a first throwing record of the garbage bag based on the throwing type and the user identification of the target user.

In one possible implementation manner, the intelligent dustbin may include a plurality of throwing areas, different throwing areas may correspond to different garbage categories, the intelligent dustbin may detect throwing positions of the garbage bags, and when the throwing positions are in any throwing area, the garbage category corresponding to any throwing area is the throwing category of the garbage bags.

In one possible implementation, different intelligent dustbin may correspond to different garbage categories, and when the target user puts in a garbage can to any intelligent dustbin, the garbage category corresponding to any intelligent dustbin is the put-in category of the garbage can.

In the embodiment of the application, the second node device corresponding to the intelligent dustbin acquires the throwing type of the dustbin, and after confirming that the throwing of the dustbin is completed, the first throwing record can be generated based on the throwing type and the user identification of the target user. The first delivery record may include a delivery type of the garbage bag and a user identifier of the target user, and of course, may also include information such as a weight, a delivery time, and the like of the garbage bag, which is not specifically limited in the embodiment of the present application.

204. The second node device stores the first drop record on a blockchain of the blockchain system.

In the embodiment of the present application, the target user may confirm the information in the first delivery record, and the second node device may store the confirmed first delivery record on the blockchain, and the process may include the following steps:

step one, the second node equipment sends the first delivery record to the target user.

In one possible implementation manner, the second node device may generate a two-dimensional code, send the two-dimensional code to the target user based on the user identifier of the target user, and the target user scans the two-dimensional code through the target application program and views the first delivery record on a target page of the target application program.

And step two, the second node equipment can store the first release record carrying the private key signature of the target user on the blockchain based on the confirmation instruction of the target user on the first release record.

In one possible implementation, the target page may include a second validation control, where the second validation control may be used to provide a form validation function, the target user may trigger a validation instruction through the second validation control, the first node device may add a private key signature of the target user to the first delivery record based on the validation instruction, and send the validation instruction and the first delivery record carrying the private key signature to the second node device, where the second node device may perform a uplink operation on the first delivery record.

In one possible implementation manner, the second node device may complete the step of uplink of the first delivery record based on the intelligent contract, specifically, when the second node device initiates a data uplink request, the second node device may trigger the intelligent contract, so that other node devices in the blockchain system acquire the public key of the target user from the blockchain based on the user identifier of the target user in the first delivery record, verify the private key signature in the first delivery record through the public key of the target user, execute the step of storing the first delivery record onto the blockchain after the verification is passed, and if the verification is not passed, not execute the storing step. The above step of storing the first delivery record on the blockchain is similar to the step of storing the user identifier and the public key of the target user on the blockchain in step 201, and will not be described herein.

After the second node device confirms that the first delivery record is correct, the first delivery record can be associated with the garbage bag, in one possible implementation manner, a label can be generated based on the first delivery record package, the label is attached to the garbage bag, and any node device can acquire the first delivery record of the garbage bag by identifying the label. It should be noted that the above description of the association manner of the first delivery record and the garbage bag is merely an exemplary description of an association manner, and the embodiment of the present application does not limit what association manner is specifically adopted.

It should be noted that, the steps 203 and 204 are steps of obtaining a delivery category of the garbage, and generating a first delivery record of the garbage on a blockchain of the blockchain system based on the delivery category and a user identifier of the target user.

In the process, the identity information of the target user is determined through face recognition, and the target user is confirmed manually to ensure that the first delivery record is accurate, so that the target user can be associated with the delivered garbage can, and further, the garbage tracing can be realized.

205. And the third node equipment acquires the category of each article in the garbage bag.

The third node device may be a server corresponding to the target garbage disposal mechanism, and in one possible implementation manner, the garbage disposal mechanism may include a garbage identification system and a garbage classification scoring system, where the garbage identification system may have an image capturing function to identify a category to which each article in the garbage bag belongs, and the garbage classification scoring system may score based on the category to which each article in the garbage bag belongs.

In the embodiment of the application, a garbage disposal mechanism can correspond to a mechanism identifier, the garbage disposal mechanism can complete enterprise real-name registration through the service provided by the environmental protection supervision mechanism, and node equipment corresponding to the environmental protection supervision mechanism can generate the mechanism identifier of the target garbage disposal mechanism and also can generate the public key and the private key of the target garbage disposal mechanism. The mechanism identification and public key of the target garbage disposal mechanism may be stored on the blockchain, the private key may be stored by the target garbage disposal mechanism itself, see fig. 5, fig. 5 is a schematic diagram of a mechanism data structure on the blockchain provided by an embodiment of the present application, and the mechanism identification and public key of the target garbage disposal mechanism may be stored in the manner shown in the area 501.

In one possible implementation manner, the object image of each object in the garbage can is identified by the garbage identification system of the target garbage disposal mechanism, and the object image is obtained based on the image identification result. Specifically, the garbage identification system of the target garbage disposal mechanism can unpack the garbage bag, collect the object images of all objects in the garbage bag, respectively perform image identification on all object images, determine the objects indicated by all object images, and further determine the category of all objects. It should be noted that the above description of the manner of acquiring the category to which each article belongs is merely an exemplary description of a manner of acquiring the category, and the embodiment of the present application is not limited to what kind of association is specifically adopted.

206. And the third node equipment acquires a garbage recycling result generated by the target garbage disposal mechanism, wherein the garbage recycling result is generated based on the first put record and the category of each article in the garbage bag.

In the embodiment of the application, after the target garbage disposal mechanism acquires the garbage can, the label on the garbage can be identified, the first delivery record carried by the label is acquired, the delivery type in the first delivery record is read, and the target garbage disposal mechanism can generate a garbage recycling result based on the delivery type and the type of each article in the garbage can. In one possible implementation, the garbage collection result may be expressed in the form of a score, the score may be used to indicate a matching degree of each article in the garbage bag with the delivery type, the garbage classification scoring system of the garbage disposal mechanism may calculate the matching degree based on a scoring rule, and further calculate the score based on the matching degree, for example, when the type of an article is the same as the delivery type, the matching degree may increase the target value, and when the type of an article is different from the delivery type, the matching degree may decrease the target value, and when the matching degree of each article in the garbage bag with the delivery type is higher, the score is higher. Wherein, the scoring rule and the target value can be set by a developer, and the embodiment of the application is not particularly limited.

In the embodiment of the application, the third node device may acquire the object image of each object in the garbage bag, the garbage collection result, the user identifier of the target user, and the mechanism identifier of the target garbage disposal mechanism, and generate a second release record, where the second release record may also include information such as when the record is generated, and the third node device may store the second release record carrying the private key signature of the target garbage disposal mechanism onto the blockchain based on the confirmation instruction of the target garbage disposal mechanism on the second release record. The process of storing the second release record on the blockchain is the same as the process of storing the user identifier and the public key of the target user on the blockchain in step 201, and will not be described herein. Referring to fig. 6, fig. 6 is a schematic diagram of a data structure of a drop record on a blockchain according to an embodiment of the present application, where the first drop record may be stored in a manner shown in an area 601, and the second drop record may be stored in a manner shown in an area 602.

Specifically, the first node device may obtain a second delivery record from the blockchain according to a target period based on the user identifier of the target user, and send the garbage collection result in the second delivery record to the target user, where the target period may be set by a developer.

In the embodiment of the application, the first node device may further obtain a total point of garbage collection of the target user. Specifically, the first node device may obtain, from the blockchain, at least one second delivery record carrying the user identifier based on the user identifier of the user, and generate, based on a garbage collection result in the at least one second delivery record, a total garbage collection score of the user on the blockchain. In one possible implementation manner, the first node device may further obtain a total point of garbage collection of at least one user, and rank the total point of garbage collection of the at least one user to obtain the current rank of the target user.
