Fig. 3 is a schematic diagram of the first flow chart of a blockchain-based material inventory data providing method provided by one or more embodiments of this specification. The method in Fig. 3 can be executed by the inventory robot in Fig. 1, as shown in Fig. 3 , The method at least includes steps S302 to S306.

S302: Acquire material inventory data of the target warehouse, where the material inventory data includes: a correspondence between robot pose information and material attribute information.

Among them, the above-mentioned robot pose information may be collected by a pose sensor in the inventory robot, the pose information may include current pose angle and current coordinate information, and the pose sensor may include: a lidar distance sensor, an accelerometer gyroscope The above-mentioned material attribute information can be collected by the radio frequency device or camera device in the inventory robot; specifically, the radio frequency device is used to collect the material label information of the material object in the target warehouse, and based on the material label information and current pose information , Generate material inventory data of the target warehouse; where the radio frequency device may be an RFID radio frequency module or other radio frequency module; The pose information generates inventory data of the target warehouse.

Among them, the above-mentioned material objects can be commodities, goods, etc. Specifically, the inventory robot moves in the target warehouse according to a preset walking route, uses the pose sensor to collect the pose information of the inventory robot, and at the same time, uses the radio frequency device to scan the material objects on the The radio frequency tag obtains the material label information, and/or uses the camera device to photograph the material object to obtain the material image information, and the first correspondence between the pose information and the material tag information, and/or the pose information and the material image The second correspondence between the information is transmitted to the material inventory module in the inventory robot, and the material inventory module determines the correspondence between the robot pose information and the material attribute information according to the first correspondence and/or the second correspondence .

Among them, in order to improve the authenticity of the robot pose information and prevent malicious users from tampering with the pose information, the pose sensor transmits the robot pose information to the navigation path finding system in the inventory robot, and the navigation path finding system controls the robot pose information. Perform signature processing and transfer the signed robot pose information to the material inventory module to ensure the authenticity and tamper-proof modification of the robot pose information, thereby ensuring the accuracy of the correspondence between the robot pose information and the material attribute information Sexuality and credibility.

S304: Use the pre-stored private key to perform signature processing on the acquired material inventory data to obtain the signed material inventory data.

Specifically, after obtaining the material inventory data of the target warehouse, the material inventory data is not directly uploaded to the cloud server, but the material inventory data is first signed, and then the signed material inventory data is uploaded to the cloud server , So that the cloud server can quickly and accurately identify whether the material inventory data comes from the inventory robot itself, and verify the credibility of the inventory robot's identity.

S306: Upload the signed material inventory data to the cloud server, so that the cloud server performs signature verification on the signed material inventory data and uploads the material inventory data that has passed the signature verification to the blockchain.

Specifically, the private key is used to sign the inventory data on the inventory robot side. Correspondingly, the public key corresponding to the inventory robot is used on the cloud server to verify the signed inventory data to identify the inventory data. Authenticity and reliability, and then credibly store the material inventory data that passed the verification into the blockchain, so that the third-party client can obtain the true, credible, and multi-party witness material inventory data from the blockchain, so that the material Inventory data is used as guidance data for subsequent business processing;

Specifically, the cloud server receives a data access request from a third-party client, where the material access request carries the identification information of the third-party client and the identification information of the target material inventory data, and the cloud server determines that the third-party client has the target After the access authority of the material data, the target material inventory data is sent to the third-party client.

In one or more embodiments of this specification, before the material inventory data of the target warehouse is uploaded to the cloud server, the inventory robot first performs trusted signature processing on the collected material inventory data to obtain the signed material inventory data, and On the cloud server side, based on blockchain technology, signature verification of material inventory data under multiple witnesses and credible on-chain is realized, which improves the authenticity, security, credibility, and tamper-proof modification of material inventory data.

Among them, for the process of cloud server signature verification of material inventory data, smart contracts can be introduced to realize the verification of material inventory data under the witness of multiple parties. Based on this, as shown in Figure 4, the above S306, the signed materials The inventory data is uploaded to the cloud server, so that the cloud server can perform signature verification on the signed material inventory data and upload the material inventory data that has passed the signature verification to the blockchain, including: S3061, the signed material inventory The data is uploaded to the cloud server, so that the cloud server uses the smart contract deployed in the blockchain to perform signature verification on the signed material inventory data, and upload the material inventory data that has passed the signature verification to the blockchain.

Specifically, after the cloud server receives the signed material inventory data uploaded by the inventory robot, it obtains the corresponding public key based on the device identification information of the inventory robot through the smart contract deployed in the blockchain, and based on the public key The key performs signature verification on the signed material inventory data, where the public key is uploaded to the cloud server by the inventory robot during the device identity activation stage.

Among them, a smart contract is a contract that can automatically execute terms defined in digital form. In the field of blockchain technology, smart contracts refer to computer programs that are triggered based on predetermined events, cannot be tampered with, and are automatically executed. The use of smart contracts can guarantee the reliable execution of all agreements and avoid tampering, denial and breach of contract. After the smart contract is released, it needs to be instantiated and validated on the state machine in the blockchain.

Among them, a smart contract can be deployed on the blockchain in advance. The smart contract includes a contract that automatically executes the material inventory data verification. The smart contract is used to verify the signed material inventory data uploaded by the inventory robot. Manual intervention, full process transparency, multi-party witness.

Specifically, in the material inventory data verification based on the smart contract, each node on the blockchain participates in the automatic execution of the smart contract, and all the execution data items (status data and status parameters) generated during the execution of the smart contract are The nodes on the chain are open and transparent, and each node on the blockchain is controlled to reach a consensus on the execution data items, and the consensus verification execution data of the inventory data is encrypted and stored in the blockchain as the signature verification result for the material inventory data, that is All execution data items generated during the execution of the smart contract are stored under the common witness of all nodes on the blockchain.

Among them, because the blockchain technology is non-tamperable, and the final signature verification result for the material inventory data and the material inventory data that have passed the verification are written into the blockchain after multiple witnesses, it can be guaranteed to be uploaded to the district. The signature verification results and material inventory data in the block chain cannot be tampered with, thereby ensuring the authenticity of the data; and the entire process of material inventory data verification and signing is automatically executed through the smart contract deployed on the blockchain, and each verification link Without manual intervention, the information of each verification link is stored on the blockchain. If the verification process of the material inventory data needs to be disclosed as a notarization in the future, the material inventory data can be directly obtained from the blockchain. Relevant information can be used as evidence.

In addition, in order to facilitate the third-party client to quickly and efficiently view the required material inventory data, which is used as the decision information to guide the subsequent business processing, the cloud server can also use the smart contract deployed in the blockchain based on the materials that have passed the verification. Inventory data, generate a classified material inventory report, and upload the classified material inventory report to the blockchain. Specifically, the material inventory data that has passed the verification can be classified according to inventory time information, material category information, and material location information, and a corresponding material inventory report can be generated.

Among them, in specific implementation, the different implementation processes that are automatically executed through smart contracts can be implemented through different smart contracts deployed in the blockchain. For example, the first smart contract deployed in the blockchain is used to perform signature verification on the signed material inventory data. The second smart contract deployed in the blockchain is used to generate a classified material inventory report based on the material inventory data that has passed the verification.

Further, in order to facilitate effective verification of the trusted identity of the inventory robot, the device identity activation binding of each inventory robot is performed in advance, and the corresponding relationship between the unique identity of the inventory robot and the public key is performed through the cloud server. Trusted on the chain, so that the follow-up can quickly and accurately verify the identity of the inventory robot, and it can also perform signature verification on the inventory data uploaded by the inventory robot, achieving dual control and storage of the inventory in the blockchain. Based on the authenticity of the data, as shown in FIG. 5, before the material inventory data of the target warehouse is obtained in S302, steps S308 to S314 are further included.

S308: If the current state of the inventory robot is the initialization state, acquire the public key of the inventory robot.

Specifically, it is judged whether the current state of the inventory robot satisfies preset conditions, where the preset conditions include: before the inventory robot leaves the factory, the inventory robot is used for the first time, or there is a change in the enterprise served by the inventory robot; if the result of the judgment is yes, then confirm The current state of the inventory robot is the initialization state, which means that the identification of the inventory robot needs to be activated and bound.

S310: Obtain identity binding information of the inventory robot, where the identity binding information corresponds to the owner of the materials inventory by the inventory robot.

Specifically, for the process of identity activation and binding for the inventory robot, not only the public key of the inventory robot needs to be obtained, but also the identity binding information of the inventory robot needs to be obtained; among them, the target warehouse simultaneously stores the materials belonging to multiple materials. In the case of objects, in order to facilitate the subsequent accurate classification of material inventory data, each inventory robot corresponds to the owner of the material it serves.

S312: Based on the obtained identity binding information and the public key, a device identity activation request of the inventory robot is generated.

Among them, the above device identity activation request carries the identity binding information of the inventory robot, the public key corresponding to the inventory robot, and can also carry the unique identifier of the inventory robot; after obtaining the public key and identity binding information of the inventory robot , Automatically generate device identity activation request.

S314: Send a device identity activation request to the cloud server, so that the cloud server responds to the device identity activation request and uploads the correspondence between the identity binding information of the inventory robot and the public key to the blockchain.

Specifically, on the inventory robot side, an identity activation input module can be set. Correspondingly, a trusted signature identity activation service is set on the cloud server. The identity activation input module in the inventory robot triggers the cloud server based on the generated device identity activation request The trusted signature identity activation service in, performs identity activation and binding operations for inventory robots, so as to realize the legal registration of the blockchain of inventory robot identities, and ensure the credibility and immutability of the inventory robot's identity.

Correspondingly, after receiving the material inventory data uploaded by the inventory robot, the cloud server not only performs signature verification on the signed material inventory data based on the public key corresponding to the inventory robot, but also based on the identity binding information corresponding to the inventory robot , To verify the authenticity of the device identity of the inventory robot, if the data signature verification is passed and the device identity verification is passed, the material inventory data will be uploaded to the blockchain;

Among them, for the process of verifying the authenticity of the device identity of the inventory robot, smart contracts can also be introduced to automatically execute. Specifically, the cloud server uses the smart contract deployed in the blockchain to perform the verification of the inventory robot based on the identity binding information corresponding to the inventory robot. The authenticity of the device identity is verified, and the corresponding device identity verification result is obtained.

In addition, for the process of the inventory robot sending the device identity activation request to the cloud server, there may be situations in which the device identity activation request fails to pass the verification, which causes the device identity binding to fail. Therefore, the cloud server can also return the identity activation to the inventory robot The response result of the request, where the response result of the identity activation request includes: the device identity binding is successful, or the device identity binding fails;

Correspondingly, when the inventory robot receives the feedback result that the device identity binding fails, it can re-send the device identity activation request to the cloud server, so that the cloud server can respond to the device identity activation request again.

Further, considering that the device identity binding fails because it is determined that the device identity activation request comes from an untrusted inventory robot, preferably, it is forbidden to return the identity activation request response result to the inventory robot, so as to avoid the untrustworthy The device re-sends the device identity activation request to the cloud server.

In view of the failure of device identity binding due to network abnormalities and other reasons, preferably, the cloud server returns the response result of the identity activation request to the inventory robot to trigger the inventory robot to re-send the device identity activation request to the cloud server.

Therefore, the cloud server responds to the above-mentioned device identity activation request, and if it is determined that the device identity binding fails, it determines whether to return the identity activation request response result to the inventory robot according to the type of cause of the device identity binding failure.

Among them, for the process of obtaining the identity binding information of the inventory robot, as shown in FIG. 6, the above S310, obtaining the identity binding information of the inventory robot, specifically includes steps S3101 and S3102.

S3101, using a camera device to scan the equipment identity graphic code displayed on the warehouse management terminal, where the equipment identity graphic code is allocated by the cloud server;

S3102: Analyze the scanned device identity graphic code to obtain the identity binding information of the inventory robot.

Specifically, the warehouse management terminal may be installed with a preset application. After detecting a trigger operation for the preset application, the warehouse management terminal automatically generates a device identity information acquisition request, and sends the device identity information acquisition request to the cloud On the server side, the cloud server responds to the device identity information acquisition request and returns corresponding device identity information to the warehouse management terminal, where the device identity information can be dynamic graphic code information or random character strings.

Specifically, taking the equipment identity information as dynamic graphic code information as an example, the warehouse management terminal displays the corresponding dynamic graphic code after receiving the dynamic graphic code information returned by the cloud server, so that the inventory robot can scan the dynamic graphic with the camera device. Code, and obtain the corresponding identity binding information.

Among them, the identity binding information (such as a random character string) can be directly input in the inventory robot, or the identity binding information can be transmitted to the inventory robot through the warehouse management terminal. Preferably, the process of triggering the distribution of dynamic graphics codes on the cloud server is set in the warehouse management terminal, and the warehouse management terminal transmits the identity binding information of the inventory robot to the inventory robot, so as to avoid the complexity of the inventory robot's work environment. In the material warehouse of, there is a problem that malicious users randomly trigger the inventory robot to send device identity activation requests to the cloud server, which causes the real identity of the inventory robot to be tampered with, which further improves the authenticity and credibility of the inventory robot.

In addition, in specific implementation, in order to further prevent malicious users from using other terminal devices to randomly trigger the inventory robot to send a device identity activation request to the cloud server, the inventory robot collects the target identification information of the warehouse management terminal after detecting the graphic code scanning trigger operation , To determine whether the target identification information is consistent with the preset identification information, if so, use the camera to scan the equipment identification graphic code displayed on the warehouse management terminal; specifically, the target identification information can be the unique serial number of the wireless communication module, MAC Address, or SIM card information.

Specifically, if it is determined that the target identification information is consistent with the preset identification information, it means that the device identity graphic code that needs to be scanned currently comes from a preset trusted warehouse management terminal, preventing malicious users from triggering the inventory robot to send to the cloud server at will Device identity activation request, so as to avoid the situation of illegally making malicious changes to the identity of the inventory robot.

Further, in view of the situation where the target warehouse stores the material objects of multiple material attribution parties, after the cloud server receives the equipment identity information acquisition request of the warehouse management terminal, it returns the equipment service company list to the warehouse management terminal; The cloud server returns the target device service company selected based on the device service company list, that is, the owner of the materials served by the inventory robot to be activated; the cloud server returns the device identity information corresponding to the target device service company to the warehouse management terminal , That is, the identity binding information of the inventory robot, so that the warehouse management terminal transmits the identity binding information to the corresponding inventory robot.

Furthermore, for the process of generating device identity activation requests, in order to improve the credibility of the public key uploaded by the inventory robot for signature verification of material inventory data, the trusted service management platform will issue a credible certificate to the inventory robot. In the process of digital certificates, since only legal devices are allowed to request the trusted service management platform to issue corresponding digital certificates, the cloud server only stores the digital certificates issued by the trusted service management platform to ensure the inventory of materials that have passed the signature verification The data is all uploaded by the legal device. Based on this, the above S312 generates the device identity activation request of the inventory robot based on the obtained identity binding information and the public key, which specifically includes: Step one, transfer the pre-stored public key Send to the trusted service management platform, so that the trusted service management platform generates a digital certificate containing the public key; step two, receive the digital certificate sent by the trusted service management platform; step three, bind based on the obtained identity The information and the received digital certificate generate the device identity activation request of the inventory robot.

Among them, because the digital certificate generated for the public key of the inventory robot is issued by a trusted organization, the digital certificate has credibility, and the subsequent cloud server can obtain the device identity when binding the device identity information of the inventory robot. The digital certificate carried in the activation request parses out the issuing authority to identify whether the received digital certificate is issued by a trusted authority, to prevent the public key of the inventory robot from being attacked, and to improve the credibility of the public key.

Specifically, each inventory robot corresponds to a pair of public and private keys. The inventory robot obtains the public key and private key assigned to it by the target server; stores the private key locally to use the The private key signs the material inventory data; and, in the process of sending the device identity activation request to the cloud server, the public key is transmitted to the cloud server so that the cloud server can record the public key and base it on the cloud server. The public key performs signature verification on the signed material inventory data.

Furthermore, for the process of generating device identity activation requests, in order to further prevent illegal elements from maliciously sending device identity activation requests to the cloud server, by adding signature processing to the identity binding information on the inventory robot side, the cloud server is receiving After the device identity activation request, the signed identity binding information is first verified to determine whether it responds to the device identity activation request. Based on this, the above step 3 is based on the obtained identity binding information and the received number The certificate generates the device identity activation request of the inventory robot, which specifically includes: using the pre-stored private key to sign the acquired identity binding information to obtain the signed identity binding information; based on the signed identity binding information and The received digital certificate generates the device identity activation request of the inventory robot.

Specifically, before the inventory robot sends the device identity activation request to the cloud server, it first signs the identity binding information, and then sends the device identity activation request to the cloud server based on the signed identity binding information to enable the cloud service After receiving the device identity activation request, the terminal performs credibility verification on the identity binding information carried in the device identity activation request, so as to ensure that the robot identity binding relationship is credible and tamper-proof.

Among them, for the situation where the identity binding information is signed on the inventory robot side and then the device identity activation request is generated, correspondingly, the device identity activation request needs to be verified on the cloud server to ensure that the robot identity binding relationship is trustworthy Based on this, the above-mentioned S314 sends a device identity activation request to the cloud server, so that the cloud server responds to the device identity activation request and counts the relationship between the identity binding information of the robot and the public key. The corresponding relationship is uploaded to the blockchain, which specifically includes: sending a device identity activation request to the cloud server, so that the cloud server responds to the device identity activation request, and based on the public key pair obtained from the trusted service management platform The signed identity binding information is verified, and after the verification is passed, the corresponding relationship between the identity binding information of the inventory robot and the digital certificate is uploaded to the blockchain.

Specifically, after receiving the device identity activation request sent by the inventory robot, the cloud server obtains the digital certificate corresponding to the inventory robot from the trusted service management platform based on the device identification information of the inventory robot; based on the acquired digital certificate The public key in the device is used to verify the signed identity binding information in the device identity activation request; if the identity binding information passes the verification, the corresponding relationship between the identity binding information of the robot and the digital certificate will be counted Upload to the blockchain; if the identity binding information fails to pass the verification, it is determined that the device identity activation request comes from an untrusted inventory robot, and it stops responding to the received device identity activation request.

In addition, after the cloud server receives the device identity activation request sent by the inventory robot, it can first verify the digital certificate in the device identity activation request, and then use the public key in the digital certificate that has passed the verification to sign. Based on this, it specifically includes: obtaining the verification key of the digital certificate corresponding to the inventory robot from the trusted service management platform based on the device identification information of the inventory robot. The key corresponds to the signature key used by the trusted service management platform to sign the public key corresponding to the inventory robot and generate the digital certificate; based on the obtained verification key, the digital certificate in the device identity activation request is verified If the digital certificate passes the verification, the public key in the digital certificate is used to verify the signed identity binding information in the device identity activation request; specifically, if the digital certificate passes the verification, it means The digital certificate is credible, therefore, the public key in the digital certificate is credible; if the identity binding information passes the verification, upload the correspondence between the identity binding information of the inventory robot and the digital certificate To the blockchain; if the verification of the identity binding information fails, it is determined that the device identity activation request comes from an untrusted inventory robot, and it stops responding to the received device identity activation request.

Furthermore, considering that the information on the blockchain is credible and cannot be tampered with, the public key certified by the blockchain is more credible than the trusted service management platform. Based on this, the inventory robot You can first apply to the blockchain for credibility certification for your own public key, so as to ensure the credibility of the public key stored on the blockchain, and then send the device identity activation with the public key after credibility certification to the cloud server. Based on this, in order to increase the credibility of the public key uploaded by the inventory robot for signature verification of the material inventory data, the blockchain will return the credibility of the inventory robot to the generation process of the device identity activation request. The process of the address on the chain corresponding to the public key, because only the legal device is allowed to request the blockchain to perform the public key credibility certification and return the corresponding on-chain address, so the cloud server only performs credibility certification on the blockchain The public key is stored to ensure that the material inventory data passed by the signature verification is uploaded by the legal device. Based on this, the above S312, based on the obtained identity binding information and the public key, generates the device identity activation of the inventory robot The request specifically includes: Step 1: Send the pre-stored public key to the cloud server, so that the cloud server uploads the public key to the blockchain, and returns it to the blockchain for storing the public key Step 2: Receive the on-chain address corresponding to the public key returned by the cloud server; Step 3: Generate an inventory based on the obtained identity binding information, the received on-chain address and the local public key The device identity activation request of the robot.

Among them, since the public key for the inventory robot has been certified by the blockchain and uploaded to the chain, and the on-chain address corresponding to the public key is returned by the blockchain, the subsequent cloud server is checking the inventory of the robot’s equipment When the identity information is bound, it can identify whether the on-chain address carried in the received device identity activation request is returned by the blockchain, so as to determine whether the public key carried in the device identity activation request is attacked, and prevent the inventory robot The public key is attacked to improve the credibility of the public key.

Furthermore, for the process of generating device identity activation requests, in order to further prevent illegal elements from maliciously sending device identity activation requests to the cloud server, by adding signature processing to the identity binding information on the inventory robot side, the cloud server is receiving After the device identity activation request, the signed identity binding information is first verified to determine whether it responds to the device identity activation request. Based on this, the above step 3 is based on the obtained identity binding information and the received chain Use the address and local public key to generate the device identity activation request of the inventory robot, which specifically includes: use the pre-stored private key to sign the obtained identity binding information to obtain the signed identity binding information; based on the signature After the identity binding information, the received digital certificate and the local public key, the device identity activation request of the inventory robot is generated.

Among them, for the situation where the identity binding information is signed on the inventory robot side and then the device identity activation request is generated, correspondingly, the device identity activation request needs to be verified on the cloud server to ensure that the robot identity binding relationship is trustworthy Based on this, the above-mentioned S314 sends a device identity activation request to the cloud server, so that the cloud server responds to the device identity activation request and counts the relationship between the identity binding information of the robot and the public key. The corresponding relationship is uploaded to the blockchain, which specifically includes: sending a device identity activation request to the cloud server, so that the cloud server responds to the device identity activation request and signs it based on the public key obtained from the blockchain After verification, the identity binding information of the inventory robot, the corresponding relationship between the address on the chain and the public key are uploaded to the blockchain after the verification is passed.

The foregoing describes specific embodiments of this specification. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps described in the claims can be performed in a different order than in the embodiments and still achieve desired results. In addition, the processes depicted in the drawings do not necessarily require the specific order or sequential order shown in order to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

In the 1990s, the improvement of a technology can be clearly distinguished between hardware improvements (for example, improvements in circuit structures such as diodes, transistors, switches, etc.) or software improvements (improvements in method flow). However, with the development of technology, the improvement of many methods and processes of today can be regarded as a direct improvement of the hardware circuit structure. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by the hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (such as a Field Programmable Gate Array (Field Programmable Gate Array, FPGA)) is such an integrated circuit whose logic function is determined by the user's programming of the device. It is programmed by the designer to "integrate" a digital system on a piece of PLD, without requiring chip manufacturers to design and manufacture dedicated integrated circuit chips. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly realized with "logic compiler" software, which is similar to the software compiler used in program development and writing, but before compilation The original code must also be written in a specific programming language, which is called Hardware Description Language (HDL), and there is not only one type of HDL, but many types, such as ABEL (Advanced Boolean Expression Language) , AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HD Cal, JHDL (Java Hardware Description Language), Lava, Lola, My HDL, PALASM, RHDL (Ruby Hardware Description), etc., currently the most Commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that just a little bit of logic programming of the method flow in the above-mentioned hardware description languages and programming into an integrated circuit can easily obtain the hardware circuit that implements the logic method flow.

For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program codes (such as software or firmware) executable by the (micro)processor. , Logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers and embedded microcontrollers.

The same function can be realized in the form of a microcontroller or the like. Therefore, such a controller can be regarded as a hardware component, and the devices included in it for realizing various functions can also be regarded as a structure within the hardware component. Or even, the device for realizing various functions can be regarded as both a software module for realizing the method and a structure within a hardware component.
