Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of an implementation environment of a garbage collection method based on a blockchain according to an embodiment of the present disclosure, and referring to fig. 1, the implementation environment may include a plurality of computer devices, where the plurality of computer devices may be a plurality of node devices in a blockchain system, and any one node device in the blockchain system may perform one or more steps in the garbage collection method based on a blockchain according to an embodiment of the present disclosure. 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 all belong to a garbage disposal facility, each department in the garbage disposal facility corresponds to at least one computer device therein, or at least one computer device in the plurality of computer devices is a user device, at least one computer device belongs to the garbage disposal facility, at least one computer device belongs to the environmental regulatory agency, and of course, there may also be at least one computer device belonging to other facilities, for example, other social regulatory agencies, and the like.

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

In order to facilitate understanding of the technical processes of the embodiments of the present application, some terms referred to in the embodiments of the present application are explained below:

block chain (Block chain): the method is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain is essentially a decentralized database, which is a string of data blocks associated by cryptography, each data block containing information about a network transaction for verifying the validity (anti-counterfeiting) of the information and generating the next block, each block containing a timestamp and a link to the previous block. In a narrow sense, a blockchain is a distributed ledger of data blocks assembled in a sequential manner into a chain data structure in chronological order and cryptographically secured as non-falsifiable and non-forgeable, i.e. the data in the blockchain will be irreversible once recorded.

Consensus mechanism (Consensus mechanism): the block chain system is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes. In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of special nodes, and if a plurality of nodes with irrelevant benefits can achieve consensus on a transaction, all the nodes in the system can also achieve consensus on the transaction.

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

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 a public part of the key pair, and the private key being a non-public part. Public keys are typically 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 that when using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt it, e.g. if the data is encrypted with the public key, the private key must be used to decrypt it, and if the data is encrypted with the private key, the public key must be used to decrypt it, otherwise the decryption will not succeed.

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

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

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

Taking the first node device as an example of a server corresponding to the client device, in this embodiment of the application, the client device may display a registration page of the target application, where the registration page may include an information input area and a first confirmation control, and when the client device detects a trigger operation of the target user on the first confirmation control, the client device may obtain input information in the information input area and send the input information and a registration request 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 one user, and the first node device may store the user identifier of the target user and the public key to a block chain of the block chain system, the private key may be stored by the target user himself. The trigger operation may be a click operation, a long-time press operation, and the like, which is not specifically limited in this embodiment of the application.

In one possible implementation, the first node device will be able to store the user identity and the public key of the target user on the blockchain based on a consensus mechanism. Specifically, each node in the blockchain system has a node identifier corresponding thereto, and each node device in the blockchain system may store node identifiers of other node devices in the blockchain system, so that the generated block is broadcast to the other node devices in the blockchain system according to the node identifiers of the other node devices, and the block is commonly identified by the other node devices. 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) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.

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 the blockchain system may store one identical blockchain. A block chain is composed of a plurality of blocks, fig. 3 is a schematic diagram of a block chain structure provided in the embodiment of the present application, referring to fig. 3, the block chain is composed of a plurality of blocks, a starting block 301 includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block 302 of the starting block takes the starting block 301 as a parent block, the next block 302 also comprises a block head and a block main body, and the block head stores the input information characteristic value of the current block 303, the block head characteristic value, the version number, the timestamp and the difficulty value of the parent block, and so on, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the security of the input information in the block is ensured.

In the embodiment of the present application, the input information may be a user identifier and a public key of the target user, after the node device checks the input information, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated, and then, an update timestamp is updated to a time when the input information is received, and different random numbers are tried, and feature value calculation is performed for multiple times, so that a feature value obtained by calculation may satisfy the following formula:

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

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. Then, the node where the block chain is located sends the newly generated current block to other nodes in the block chain system where the block chain is located according to the node identifiers of the other nodes in the block chain system, the other nodes perform consensus on the newly generated current block, the current block can be added to the block chain after passing the consensus, and certainly, if the current block does not pass the consensus, the block uplink operation may not be performed. Referring to fig. 4, fig. 4 is a schematic diagram of a block chain user data structure provided in this embodiment of the present application, where the user identifier and the public key of the target user may be stored in a manner shown in an area 401.

step one, when receiving a garbage throwing instruction of the target user, the second node device may 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 throwing instruction can be triggered by clicking operation on a target control on the intelligent garbage can. In a possible implementation manner, a target control may be configured on the intelligent trash can, the target control may provide a function of starting a trash throwing process, and of course, the intelligent trash can may further have an image collecting function. The target user can trigger a garbage throwing instruction by clicking the target control, so that the target garbage can executes the subsequent image acquisition step.

(2) The garbage throwing instruction can be triggered by the uncovering operation of the intelligent garbage can. This intelligence dustbin can detect target user's operation, when detecting this target user's the operation of uncapping, can trigger this rubbish and put in the instruction.

After receiving the garbage throwing instruction, the intelligent garbage can collect a user image of the target user, wherein the user image can be a facial image of the target user. The intelligent trashcan can 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 a face recognition technique to recognize the user image to determine the user identifier of the target user. Specifically, first, the second node device may perform face detection on the user image based on a structural distribution feature of a 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 and a size of the face and position information of each main facial organ; then, the second node device may calculate a plurality of geometric feature quantities according to information of five sense organs in the key information of the face, and construct feature data that may describe facial features of the target user based on the plurality of geometric feature quantities; and finally, searching and matching the feature data with a feature template which can be stored in data, acquiring the feature template with the 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 only an exemplary description of a face recognition method, and the embodiment of the present application does not limit which 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 intelligent trash can be configured with an information input area that can provide a user identification input function for a user. The intelligent garbage can detect the information input operation of a target user in the information input area, and when the information input operation is finished, the input information of the target user is obtained and used as the user identification of the target user.

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

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

In a possible implementation manner, the intelligent garbage can may include a plurality of throwing areas, different throwing areas may correspond to different garbage categories, the intelligent garbage can may detect a throwing position of the garbage bag, and when the throwing position is in any throwing area, the garbage category corresponding to the any throwing area is the throwing category of the garbage bag.

In a possible implementation manner, different intelligent garbage cans may correspond to different garbage categories, and when the target user puts a garbage bag into any intelligent garbage can, the garbage category corresponding to the any intelligent garbage can is the putting category of the garbage bag.

In this embodiment of the application, the second node device corresponding to the intelligent trash can obtains the delivery category of the trash bag, and after the completion of the delivery of the trash bag is confirmed, a first delivery record may be generated based on the delivery category and the user identifier of the target user. The first delivery record may include a delivery category of the spam package and a user identifier of the target user, and may also include information such as a weight of the spam package and a delivery time, which is not specifically limited in this embodiment of the present application.

204. The second node device stores the first delivery record to a blockchain of the blockchain system.

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

In a 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 device may store the first release record carrying the private key signature of the target user to the block chain based on a confirmation instruction of the target user for the first release record.

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

In a possible implementation manner, the second node device may complete the uplink procedure of the first release record based on an intelligent contract, and specifically, when the second node device initiates a data uplink request, may trigger an intelligent contract, so that other node devices in the blockchain system obtain a public key of a target user from the blockchain based on a user identifier of the target user in the first release record, verify a private key signature in the first release record by using the public key of the target user, after the verification is passed, execute a procedure of storing the first release record onto the blockchain, and if the verification is not passed, do not execute the storage procedure. The step of storing the first delivery record in the blockchain is the same as the process of storing the user identifier and the public key of the target user in the blockchain in step 201, and will not be described herein again.

After the second node device confirms that the first release record is correct, the first release record may be associated with the trash bag, in a possible implementation manner, a label may be generated based on the first release record package, the label is attached to the trash bag, and any node device may obtain the first release record of the trash bag by identifying the label. It should be noted that the above description of the association manner between the first delivery record and the spam package is only 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, in step 203 and step 204, the release category of the garbage bag is obtained, and based on the release category and the user identifier of the target user, a first release record of the garbage bag is generated on the blockchain of the blockchain system.

In the process, the identity information of the target user is determined through face recognition, the first delivery record is guaranteed to be accurate through manual confirmation of the target user, the target user can be associated with the delivered garbage bag, and then garbage tracing can be achieved.

In this embodiment, one garbage disposal mechanism may correspond to one mechanism identifier, the garbage disposal mechanism may complete enterprise real-name registration through a service provided by an environmental protection regulatory mechanism, and a node device corresponding to the environmental protection regulatory mechanism may generate a mechanism identifier of the target garbage disposal mechanism, and may also generate a public key and a private key of the target garbage disposal mechanism. The institution identification and the public key of the target garbage disposal facility can be stored in the blockchain, and the private key can be stored by the target garbage disposal facility, referring to fig. 5, where fig. 5 is a schematic diagram of a data structure of an institution on the blockchain according to an embodiment of the present disclosure, and the institution identification and the public key of the target garbage disposal facility can be stored in a manner shown in an area 501.

In one possible implementation manner, the category of each article in the garbage bag is obtained by the garbage recognition system of the target garbage disposal mechanism through image recognition of the article image of each article in the garbage bag based on the image recognition result. Specifically, the trash recognition system of the target trash disposal mechanism can unpack the trash, collect the article images of the articles in the trash, respectively perform image recognition on the article images, determine the articles indicated by the article images, and further determine the category to which the articles belong. It should be noted that the above description of the category mode of acquiring each article is only an exemplary description of one category acquisition mode, and the embodiment of the present application does not limit what association mode is specifically adopted.

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

In this embodiment of the application, after the target garbage disposal mechanism obtains the garbage bag, the target garbage disposal mechanism may identify the tag on the garbage bag, obtain the first release record carried by the tag, read the release category in the first release record, and generate the garbage collection result based on the release category and the category to which each item in the garbage bag belongs. In a possible implementation manner, the garbage collection result may be in the form of a score, where the score may be used to indicate a matching degree between each article in the garbage bag and the release category, and the garbage classification scoring system of the garbage disposal mechanism may calculate the matching degree based on the scoring rule, and further calculate the score based on the matching degree, for example, when the category to which an article belongs is the same as the release category, the matching degree may increase a target value, when the category to which an article belongs is different from the release category, the matching degree may decrease the target value, and the higher the matching degree between each article in the garbage bag and the release category is, the higher the score is. The scoring rule and the target value may be set by a developer, and the embodiment of the present application is not particularly limited.

In this embodiment of the application, the third node device may obtain an article image of each article in the trash bag, the trash recovery result, the user identifier of the target user, and the mechanism identifier of the target trash processing mechanism, and generate a second delivery record, where of course, the second delivery record may further include information such as when the record is generated, and the third node device may store the second delivery record carrying the private key signature of the target processing mechanism to the block chain based on a confirmation instruction of the target trash processing mechanism on the second delivery record. The process of storing the second delivery 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 details are not repeated here.

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