The embodiment discloses a method for managing smart city emergency materials, referring to fig. 1, comprising the following steps S110-S160:

s110, acquiring the material calling data input by the user before the emergency material corresponding to the material calling data is sent out.

The embodiment of the application discloses a management method of smart city emergency materials, which is applied to user equipment 201, referring to fig. 2, the user equipment 201 is connected with management equipment 202, and meanwhile, the user equipment 201 is also connected with a plurality of verification equipment 203, and the user equipment 201, the management equipment 202 and the plurality of verification equipment 203 form a data management system. The user device 201 is a computer device used by a user, and is used for inputting material call data into a system and other operations. The management device 202 is a computer device used by a management participant to verify data entered by the user device 201. The verification device 203 is also a computer device used by other management participants, and is used for performing secondary verification on the data input by the user device 201, verifying the authority of the management device 202, and storing the encrypted data. In the data management system, the user device 201, the management device 202 and the verification device 203 are in peer-to-peer state, and in different data verification processes, the user device 201 or the management device 202 can be used as the verification device 203, and the verification device 203 can also be used as the management device 202.

The user device 201, the management device 202, and the verification device 203 include, but are not limited to, electronic devices such as a mobile phone, a tablet computer, a wearable device, a PC (Personal Computer ), and the like, and may also be a background server running a smart city emergency material management method. The server may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.

When a user needs to manage emergency material data, including but not limited to, after purchasing, storing, allocating, distributing, recovering, etc., the emergency material data is managed, material calling data is input to the user device 201. The material calling data comprises information such as the type, the number, the material delivery time, the expected delivery time and the like of emergency materials to be called, and account information of a user uploading the material calling data, wherein the account information can be the name, the identification card number or an internal account number of the user and the like and is used for uniquely determining the identity of the user.

S120, acquiring account information of the user, writing the account information into material calling data to obtain first calling data after the account information is verified, and sending the first calling data to the management device 202.

After receiving the material calling data, the user equipment 201 obtains account information input by the user through the related interaction interface, and judges whether the user has the authority of modifying the emergency material data according to the account information. If the user is inquired to have the authority of modifying the emergency material data, the verification is passed, and the user is indicated to upload the material calling data to the data management system. Further, the user equipment 201 writes account information of the user to a position corresponding to the material calling data, so as to obtain first calling data. The first call data is then sent to the management device 202 of the management participant for further inspection and review of the material call data by the management participant.

S130, after the management device (202) verifies that the material delivery time contained in the first call data meets the preset condition, receiving first verification passing information sent by the management device (202).

After receiving the first call data sent by the user, the management device 202 verifies the first call data, including verifying the usage amount, the usage location, etc. of the emergency materials in the verification data, checking whether the user meets the relevant rule of the system, and checking whether the identity of the user is wrong. The most important need is to verify the delivery time of the supplies, since the time-dependent verification of urban emergency supplies is one of the core elements of urban emergency supply management, which ensures rapid and accurate allocation and distribution of supplies in emergency situations. Timely response to emergency events such as natural disasters, public health crisis and the like can reduce the influence of disasters to the greatest extent and ensure the life safety of citizens. Other types of material verification are relatively weak for timeliness verification and relatively low in importance relative to urban emergency material.

For timeliness verification, the management participation can input disaster occurrence time to the management equipment, and the management equipment calculates a difference value between the material delivery time and the disaster occurrence time and judges whether the difference value is smaller than a preset threshold value. If the difference is greater than or equal to the preset threshold, indicating that the delivery time of the emergency supplies is too late, the verification is not passed. Otherwise, if the difference value is smaller than a preset threshold value, the fact that the material delivery time of the emergency material meets the preset condition is indicated, and verification of the first call data is passed. Of course, whether the material delivery time of the first call data meets the preset condition or not may also be verified manually by the management party, and after the management party determines that the first call data has no problem, the management party inputs verification passing information to the relevant interactive interface of the management device 202. The management device 202 then sends first authentication pass information to the user device 201, the first authentication pass information comprising a first device identification of the management device 202 and first invocation data.

S140, the first authentication passing information is randomly transmitted to the plurality of authentication devices 203.

And S150, after the emergency materials corresponding to the material calling data are sent to the corresponding material receiving party, receiving second verification passing information of the verification devices 203.

Urban emergency materials belong to relatively sensitive information, and have higher requirements on safety and accuracy. In a conventional blockchain system, a plurality of nodes in the blockchain system communicate with each other to ensure that data can be synchronized at all nodes. In the application, the block chain system is improved based on the thought of the block chain. In particular, the verification devices 203 are similar to nodes in a blockchain system for data verification and storage, but no communication nor data synchronization is performed between any two verification devices 203 in the present application. This prevents the transmission of a malicious virus through one authentication device 203 to other authentication devices 203 communicatively connected thereto, causing leakage of material management data or tampering.

Before randomly transmitting the first authentication pass information to the plurality of authentication devices 203, the user device 201 establishes a communication connection with the plurality of authentication devices 203 through a network communication protocol such as TCP/IP or HTTPS. The user device 201 determines the number of authentication devices 203, i.e. the number of authentication devices 203, that have established a communication connection. Each authentication device 203 is numbered according to the number of authentication devices 203 that establish communication connection. The device number may use a positive integer, starting with 1 and incrementing until the number of devices. The user device 201 generates the same number of random integers as the authentication devices 203. These random integers may be set to an integer range from 1 to the number of devices. The user device 201 determines the corresponding authentication device number from the generated random integer and sends the first authentication pass information to these authentication devices 203.

The determination of the number and the number of the devices provides a basis for subsequent random selection. Then, the generated random integer corresponds to the device number, so that each verification device 203 has an opportunity to receive the verification information, and the fairness of verification is ensured. Finally, the first verification passing information is sent to the verification device 203 corresponding to the corresponding number, so that the correct verification device 203 is ensured to receive and complete the verification of the second stage. Thereby effectively avoiding excessive centralization of the verification device 203 or biasing towards a certain device, and improving the fairness of verification. Meanwhile, by randomly selecting the verification device 203, the security of verification is increased, and possible attacks or fraudulent behaviors are prevented.

After receiving the first verification passing information, the plurality of verification devices 203 verify the first verification passing information. The target authentication device is illustrated with any one of a plurality of authentication devices 203, 203. The user device 201 determines a target authentication device from the generated random integer, and transmits first authentication passing information to the target authentication device. The transmitted information includes the first device identifier of the management device 202, and related information such as the first call data. The target authentication device receives the first authentication pass information from the user device 201. And the user of the target verification device verifies the received material calling data, so that the data format is correct, the integrity is not damaged, and the like.

In order to ensure that emergency management materials are timely sent to a material receiving party and that the quantity of the materials is not lost, the target verification device needs to verify the transportation time of the emergency materials and the quantity of the materials. After receiving the emergency materials, the material receiver needs to send second call data to each verification device (including the target verification device) through the related device at the same time, wherein the second call data comprises the material receiving time and the material quantity of the emergency materials. After the target verification device receives the second call data, calculating the difference between the material receiving time and the material delivery time, and then judging whether the difference between the material receiving time and the material delivery time meets a preset difference value. And judging whether the quantity of the received materials is consistent with the quantity of the emergency materials contained in the first verification passing information. If the difference between the material receiving time and the material delivery time meets the preset difference, and if the quantity of the received materials is consistent with the quantity of the emergency materials contained in the first verification passing information, the fact that the emergency materials are transported is indicated to be free of problems, and the correctness check of the first calling data is passed.

The target verification device verifies the data verification authority of the management device 202 using the first device identifier, ensuring that the management device 202 is legal and has the authority of data verification. It may be equivalent to determining whether the management participant corresponding to the management device 202 has data verification authority by querying from the database whether the management device 202 corresponding to the first device identification has data verification authority. If the correctness check of the first call data is passed and the data check authority check of the management device 202 is passed, the target verification device generates second verification passing information and transmits the second verification passing information to the user device 201, and the user device 201 receives the second verification passing information from the target verification device.

After the emergency material corresponding to the material calling data has been sent to the corresponding material receiving party, the user device 201 introduces the target verification device for additional verification before receiving the second verification passing information of the plurality of verification devices 203. After receiving the first verification passing information, the target verification device verifies the difference between the material receiving time and the material delivery time and the consistency of the material quantity in detail, and verifies the data verification authority of the management device 202 according to the first device identification. Only after all of these authentication conditions are passed, the target authentication device transmits second authentication pass information. Multi-level verification of material calling data is added, and the accuracy and safety of the verification process are improved through participation of verification equipment 203. By accurately verifying the material receiving time and quantity and checking the authority of the management equipment 202, the authenticity and the credibility of the emergency material data are ensured. This helps to reduce the risk of the system being subjected to malicious attacks or data errors, improving the overall reliability and accuracy of the smart city emergency materials management system.

Next, the user device 201 determines the number of devices of the authentication devices 203 that establish communication connection, and after receiving the second authentication passing information transmitted by the plurality of authentication devices 203, records the received information number. The user device 201 compares the amount of information received with the number of authentication devices 203 in the system. If the number is the same, it is interpreted that each authentication device 203 has authenticated and transmits second authentication passing information. If the number of information is the same as the number of devices, it is indicated that each of the authentication devices 203 has successfully completed the authentication process and that the user device 201 can trust the authentication results of these authentication devices 203. At this time, the user equipment 201 can confirm that the authentication process of the first authentication passing information is correct, and continue the subsequent data encryption flow.

After the plurality of verification devices 203 verify that the first verification passing information passes, a step of judging the number of devices and the number of information is introduced to further confirm the accuracy and consistency of the verification process. By determining the number of the plurality of authentication devices 203 and then confirming the number of the received second authentication pass information, the user device 201 can dynamically detect and compare whether the two are identical. If the two numbers are consistent, each verification device 203 is indicated to pass the verification successfully, and the integrity and correctness of the whole verification process are further ensured. The design effectively prevents possible verification errors or data inconsistency, provides an additional safety layer for emergency material data management, enhances the monitoring and control of the verification process, and improves the verification reliability.

And S160, writing the first equipment identifier and a plurality of second equipment identifiers into the first call data to obtain intermediate data.

The user device 201 writes the received first device identifier of the management device 202 and the received second device identifiers of the plurality of verification devices 203 into the material calling data, and adds corresponding fields or tags in the data packet at corresponding positions of the material calling data to complete writing of the first device identifier and the plurality of second device identifiers into the material calling data, so as to obtain intermediate data, so that after problems occur in the material calling data, tracing can be performed according to data content.

The policy of the multi-layer verification and random verification device 203 ensures the authenticity and integrity of the asset call data. The user equipment 201 firstly acquires the material calling data input by the user, and generates the first calling data after verifying the user account information, so that the source of the calling data and the legality of the user identity are ensured. Subsequently, by randomly transmitting the first verification passing information to the plurality of verification devices 203, a mechanism of randomness and distributed verification is introduced, so that the risk of a single verification channel is effectively prevented, and the security of the overall verification is improved. Before the emergency materials corresponding to the material calling data are sent out, the management device 202 verifies the time condition of the first calling data, and further ensures that the sending time of the materials meets the preset condition. And then, the second call data sent by the material receiving party is verified through the plurality of verification devices 203, so that the difference between the material receiving time and the material delivery time is ensured to meet the preset difference value, the material quantity is consistent, and the first device identification is verified to pass, so that the actual effectiveness of the material call data is ensured. And finally, writing the first equipment identifier and the plurality of second equipment identifiers into the first call data to form intermediate data, so that the whole verification process has multi-level security guarantee. The design of the multiple verification and random verification device 203 effectively reduces the possibility of tampering or falsifying call data, and improves the accuracy and the credibility of emergency material data management.

In one possible implementation, biometric data of a user is obtained; performing hash operation on the biological characteristic data to obtain a biological characteristic array; extracting a preset number of characters from the biological characteristic array according to a preset mode to obtain a user private key; and generating a user public key by adopting an asymmetric encryption algorithm according to the user private key.

Specifically, biometric data of the user is acquired using a biometric device (e.g., a fingerprint sensor, a facial recognition camera, etc.) or other biometric acquisition device. This may include fingerprint images, facial features, etc. And carrying out hash operation on the acquired biological characteristic data, and marking an obtained operation result as a biological characteristic array. The hash operation is a one-way encryption operation that maps biometric data to a hash value of a fixed length. This ensures that the biometric data of the user is not stored directly, protecting privacy. A predetermined number of characters are extracted from the biometric array in a predetermined manner, which characters will be used as a basis for generating a user private key. The preset manner may include random selection, selection according to a specific rule, etc., but the user equipment 201 needs to memorize the preset manner so that the extraction manner is the same each time. The extracted characters are used as seeds, and a user private key is generated by combining identity information of a user or other factors in a cryptographically secure mode. This may use a cryptographically secure pseudo-random number generation algorithm. Using the user private key as input, an asymmetric encryption algorithm (e.g., RSA, DSA, etc.) is employed to generate a corresponding user public key. In an asymmetric encryption algorithm, the private key and the public key are a pair, where the private key is used for encryption and the public key is used for decryption (or vice versa, depending on the specific design of the algorithm).

Firstly, acquiring biological characteristic data of a user, and carrying out hash operation on the biological characteristic data to obtain a biological characteristic array. The user private key is formed by extracting a preset number of characters from the array, so that the user private key has the uniqueness and the non-counterfeitability of biological characteristics. And then, generating a user public key by adopting an asymmetric encryption algorithm according to the user private key, so that the safety corresponding relation between the public key and the private key is ensured.

After the user public key and the user private key are generated, the user private key is usually stored by the user, and is not externally published, but the user public key can be externally published. The user device 201 encrypts the intermediate data according to the user public key using a suitable encryption algorithm to obtain encrypted data. So that only the user can decrypt the encrypted data using the user private key to obtain intermediate data. After generating the encrypted data, the user device 201 transmits the encrypted data to each authentication device 203 according to the received plurality of second device identifications, so that the authentication device 203 stores the encrypted data. After the transmission is completed, the user device 201 deletes the local material call data, so that only the verification device 203 in the system contains the encrypted material call data.

Further, a digital signature needs to be generated to facilitate verification of the decrypted encrypted data, so as to prevent the encrypted data stored in the verification device 203 from being tampered, thereby affecting the accuracy of the data. Specifically, first, the user device 201 hashes the intermediate data to obtain verification data. The hash is a one-way, irreversible algorithm that maps intermediate data into hash values of fixed length. And then encrypting the generated verification data by using a user private key to obtain a digital signature. The encryption process requires an asymmetric encryption algorithm to ensure that the digital signature can only be decrypted by the corresponding user public key. Referring to the transmission process of the encrypted data, the user device 201 transmits the generated digital signature to each authentication device 203 according to the second device identification.

Firstly, the user public key is adopted to encrypt the intermediate data to obtain encrypted data, and the encrypted data is sent to each verification device 203 according to the second device identifier, so that the encryption protection of data transmission is realized. The method effectively prevents the intermediate data from being accessed or tampered by unauthorized parties in the transmission process, and ensures the confidentiality of the data. The intermediate data is hashed to generate verification data, and the verification data is encrypted with a user private key to generate a digital signature, which is then sent to each verification device 203. The digital signature can be used for subsequent verification of the correctness of the encrypted data, and the encrypted data is prevented from being tampered. Since the decrypted digital signature should be identical to the result of the intermediate data hash operation, otherwise, it is indicated that the encrypted data may be tampered with. After the verification of the material calling data is completed, the steps of encryption and digital signature are introduced, so that the safety and the credibility of the data are further improved.

If the user needs to view the original material call data, since not all the verification devices 203 store the encrypted data, the encrypted data downloaded from the verification device 203 needs to be verified according to the second device identifier, and the verification device 203 corresponding to the second device identifier stores the encrypted data. After receiving the verification request, the user device 201 searches the corresponding verification device 203 according to the second device identifier, and downloads the digital signature and the corresponding encrypted data from the verification device 203. And then, the user inputs a corresponding private key through the related interactive interface, so that the private key is ensured not to be revealed. Using the private key entered by the user, the user device 201 decrypts the downloaded encrypted data to obtain intermediate data. And then carrying out hash operation on the intermediate data to obtain the data to be verified. If the encrypted data is not tampered with, the resulting data to be authenticated should be identical to the authentication data generated in the previous step.

And the user device 201 decrypts the downloaded digital signature using the user public key to obtain the authentication data. The user device 201 compares the data to be verified obtained by the hash operation with the verification data obtained by decryption. If the data are consistent, the encrypted data are not tampered, namely the encrypted data are encrypted by the original intermediate data.

First, the digital signature and the encrypted data are downloaded from the authentication device 203 according to the second device identification, ensuring the reliability of data acquisition. Then, the user inputs a private key for decrypting the encrypted data to obtain intermediate data, and then the data to be verified is generated through hash operation. And decrypting the digital signature by using the user public key to obtain verification data, and judging the consistency of the data to be verified and the verification data, so as to confirm the integrity of the encrypted data. The process effectively prevents possible falsification or counterfeiting risks in the data transmission and decryption processes, and improves the security and the credibility of data storage.
