Exemplary embodiments will be described in detail here, examples of which are shown in the drawings. When referring to the drawings below, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of this specification. Rather, they are merely examples of devices and methods consistent with some aspects of one or more embodiments of this specification as detailed in the appended claims.

It should be noted that in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. In addition, the single step described in this specification may be decomposed into multiple steps for description in other embodiments; and the multiple steps described in this specification may also be combined into a single step in other embodiments. description.

With the development of Internet technology, network-based service models are constantly being updated. For the server and the serviceee who are not familiar with each other, due to the strangeness between them, many security risks may be brought about. This security risk is especially prominent in service models such as remote service or on-site service.

Based on the technical status and problems raised above, FIG. 1 is a data processing method based on a blockchain shown in an embodiment provided in this specification, and the blockchain includes a service platform node device.

The service platform described in this embodiment may include a platform-type service organization that accepts a certain type of service demand or service provision from a user, and performs services such as service matching or service allocation, such as on-site services (such as housekeeping services, maintenance services, and tutoring) Service) business matching platform, remote service (such as distance learning) business matching platform, etc., not limited in this manual.

The blockchain described in this embodiment may specifically refer to a P2P network system with distributed data storage structure reached by each node through a consensus mechanism. The data in the blockchain is distributed in time-connected "areas" Within the "block", the latter block contains the data summary of the previous block, and according to the specific consensus mechanism (such as POW, POS, DPOS, or PBFT, etc.), complete data backup of all or some nodes is achieved . Those skilled in the art are familiar with the fact that since the blockchain system operates under the corresponding consensus mechanism, the data that has been included in the blockchain database is difficult to be tampered with by any node. For example, the blockchain using Pow consensus requires at least the entire network Only an attack of 51% computing power can tamper with the existing data, so the blockchain system has the characteristics of ensuring data security and preventing attack and tampering that other centralized database systems cannot match. It can be seen that, in the embodiment provided in this specification, the data included in the distributed database of the blockchain will not be attacked or tampered, thereby ensuring that the service platform node device deposits the certificate to the blockchain The authenticity of data information.

The service platform node device described in this embodiment may join the blockchain as a node of the blockchain by following the installation of the corresponding node protocol and running the node protocol program.

Step 102: The service platform node device obtains order information sent by a service demanding terminal, where the order information includes required service content.

The service demanding terminal described in this embodiment sends order information to the service platform node device during communication with the service platform node device. The above-mentioned order information may include the service content required by the service demanding party, and the required service content includes: service type content, or the condition that the service provider should satisfy, etc., so that the service platform can perform services for both parties based on the above order information Matching, matching or distribution.

Step 104: Based on the order information, send order allocation information to the service provider terminal to allocate the service provider to the service demanding terminal, wherein the distributed service database of the blockchain has the above service provision The identity identification information of the party is used for the identity verification comparison of the service provider when providing the service.

The distributed database of the blockchain holds the identification information of the service provider, which is used to compare and verify the identity of the service provider who actually provides the service, to prevent the service provider registered with the above service platform from receiving orders. The service providers who actually provide services afterwards do not belong to the same user, which may cause hidden security risks.

The above identification information may include identity document information (such as ID card pictures, ID numbers, etc.), biological identification information (such as fingerprints, features, voiceprints, irises, and other identification information) to determine the identity of the service provider.

The service provider may enter the above identification information into the service platform node device when registering as the service provider of the above service platform, and the above service platform node device will deposit the above identification information to the distributed blockchain Database. It is worth noting that there are many specific ways to deposit the above identification information in the distributed database of the blockchain. In addition to backing up the original text of the above identification information to the distributed database of the blockchain, each The node equipment is backed up and maintained together; because the identification information of the above service provider is usually very sensitive personal privacy information of the user, the above identification information can also be encrypted and published in the distributed database of the blockchain to prevent the blockchain The other node devices in are illegally applied after acquiring the above identification information.

In another embodiment shown, the specific way of storing the identification information in the distributed database of the blockchain can also be expressed as: the service platform node device collects the identification information of the service provider, and the service The digest of the provider's identification information (such as the hash digest value) is sent to the distributed database of the blockchain to deposit the identification information of the above service provider.

In this embodiment, the identity identification information of the service provider stored in the distributed database of the blockchain is used for the identity verification comparison of the service provider when providing the service. The above-mentioned identity verification comparison may include various specific implementation processes.

In an illustrated embodiment, the identity verification comparison is performed by the service platform node device, and the specific process may include:

When the service provider receives the order allocation information sent by the service platform, it will provide services according to the needs of the service demand side; when providing the corresponding service, in order to ensure that the actual service provider is indeed the service provider specified for the above order allocation information, The terminal of the service provider or service demander will collect the actual identification information of the actual service provider, such as face recognition or inspection of the actual service provider to collect their identity documents, etc., and will collect the existing identities collected above The identification information is sent to the service platform node device for the service platform node device to perform identity verification comparison;

After receiving the identity verification information sent by the service provider terminal or the service requester terminal, the service platform node device based on the identity identification information of the corresponding service provider in the order allocation information stored in the blockchain The identity identification information stored is compared with the above existing identity information; and the result of the comparison is sent to the service demanding terminal or the service provider terminal, so that the service demanding side confirms the actual service provider at this time Is it the same person as the service provider specified in the order allocation information?

In yet another illustrated embodiment, the above identity verification comparison may be performed by the service provider terminal or the service demander terminal. The specific process may include: the above service platform node device obtains the identity identification information of the service provider stored in the distributed database of the blockchain; and sends the service provider terminal or the service demander terminal The identity identification information, so that the service provider terminal or the service demand side terminal performs identity verification comparison with the service provider based on the identity identification information; receiving the service provider terminal or the service The identity verification comparison result sent by the demanding terminal.

The above two embodiments are only two specific implementation methods for verifying and comparing the identity information of the service provider. This specification does not limit the identity identification information pair of the service provider in the distributed database based on the blockchain The implementation process and execution subject of the actual service provider's identity verification comparison, all the identity identification information of the service provider based on the distributed database of the blockchain is compared with the actual service provider's identity verification to obtain The comparison results of identity verification belong to the scope of protection of this manual.

Step 106: Receive the service content actually provided by the service provider sent by the service demander terminal or the service provider terminal.

Specifically, the service content actually provided by the above service provider may include: positioning information of the service provider node device (to indicate that the service provider has reached the service location), and the comparison result of the identity verification of the service provider (use To indicate that the service provider is one or more of the service provider specified in the order allocation information), service provider start service time, service provider end service time, service process memo information, etc.

The content of the service actually provided by the above service provider may be sent by the service requester terminal or may be sent by the service provider terminal, depending on actual business needs or processes, and is not limited in this specification.

Step 108: Send a service deposit transaction to the blockchain, so that the service deposit transaction is included in the distributed database of the blockchain after being verified by the blockchain consensus; the service deposit transaction It is used to deposit certificates for the service content actually provided by the service provider.

The transfer described in this specification refers to a piece of data created by the node device of the blockchain and needs to be finally released to the distributed database of the blockchain. Among them, there are transactions in the narrow sense and transactions in the broad sense in the blockchain. A narrowly defined transaction refers to a value transfer issued by the user to the blockchain; for example, in the traditional Bitcoin blockchain network, the transaction can be a transfer initiated by the user in the blockchain. The generalized transaction refers to a piece of business data released by the user to the blockchain with business intent; for example, the data posted to the blockchain described in the above embodiments of this specification for the actual provision of service providers The data of the service content of the certificate can be a transaction; or the above completed service content can be organized according to the preset transaction data format, so as to be converted into a transaction.

The service certificate deposit transaction described in this embodiment is used to deposit a certificate for the service content actually provided by the service provider or completed. For example, a service provider terminal or a service demander terminal may upload a series of related service contents provided by the service provider or a series of related service actions performed to the above service platform node device from the time the service provider reaches the service location. The service platform node device can supervise the service content provided by the service provider, and the service platform node device can enable the service content actually provided by the provider to deposit certificates in the distributed database of the blockchain.

Specifically, the service content actually provided by the above service provider may include: positioning information of the service provider node device (to indicate that the service provider has reached the service location), and the comparison result of the identity verification of the service provider (use To indicate that the service provider is one or more of the service provider specified in the order allocation information), service provider start service time, service provider end service time, service process memo information, etc. Correspondingly, the above service deposit transaction may include the original text or encrypted ciphertext of the service content actually provided by the above service provider, or a mathematical summary (such as a hash summary) of the service content actually provided by the above service provider to provide the above service The actual content of the service provided by the party shall be certified.

The detailed process of uploading the service deposit transaction to the distributed database of the blockchain described in the above embodiments may be specifically set according to the consensus mechanism and transaction rules of the blockchain. In an illustrated embodiment, uploading the service deposit transaction to the distributed database of the blockchain includes:

The node device with the accounting authority in the blockchain adds the service deposit transaction to the candidate block;

Determine, from the node devices with accounting authority, a consensus accounting node device that satisfies the blockchain consensus mechanism;

The consensus accounting node broadcasts the candidate block to the node device of the blockchain;

After the candidate block passes the verification and approval of the node device that the blockchain meets a preset number, the candidate block is regarded as the latest block and is added to the distributed database of the blockchain.

In the above embodiments, the node device with accounting authority refers to the node device with authority to generate candidate blocks. According to the consensus mechanism of the blockchain, a consensus billing node device can be determined from the node devices with accounting authority of the candidate block, and the above consensus mechanism may include a proof of work mechanism (PoW) or a proof of rights mechanism ( PoS), or share authorization mechanism (DPoS), etc.

The PoS or DPoS consensus mechanism is similar to PoW, and both belong to the consensus algorithm commonly used in the public blockchain to confirm the consensus accounting node equipment. In another embodiment shown, in order to reduce the transaction or data confirmation time, improve transaction throughput, and meet the requirements for security and performance, the embodiments provided in this specification can also use the alliance chain architecture to construct the block chain. The above-mentioned service platform node equipment, or an institution that supervises related service business, can be used as the pre-selected node equipment of the alliance chain to participate in the block accounting. The consensus process of the alliance chain is also controlled by the pre-selected node device. When there is a node device on the network that exceeds a set ratio (such as 2/3) to confirm a block, the transactions or data recorded in the block will be confirmed by the entire network.

The alliance chain usually adopts proof-of-stake or consensus algorithms such as PBFT and RAFT. During implementation, before each round of consensus of the blockchain, a master node device can be elected from each node device in the blockchain, that is, the consensus accounting node (for example, each A round of consensus re-elects a master node device, and other node devices are used as slave node devices). The master node device further verifies and initiates the transaction and consensus, and is responsible for the transaction data (or target data) based on the consensus as the block The chain creates the latest block.

As a preferred implementation of the consensus algorithm of the alliance chain provided in this specification, the PBFT algorithm is due to the high efficiency of consensus using this algorithm, which can meet the needs of high-frequency transaction volume. For example, in this embodiment, the service platform is based on Generate service registration transactions with frequently occurring order information; and the consensus delay is very low, basically meeting the requirements of real-time processing, and the above service registration transactions can be included in the new block of the blockchain quickly and in real time; As a pre-selected accounting node, the trusted node in the alliance chain network takes into account the security and stability; in addition, the use of the PBFT algorithm will not consume too much computing power resources, nor does it necessarily require token circulation, so it has a good Usability.

Based on the service method provided in this embodiment, the distributed database storage mechanism based on blockchain technology, the actual completed service content is decentralized and recorded in multiple blockchain nodes, jointly maintained by the blockchain nodes, real-time Synchronization, all records can be traced back; and, based on the consensus mechanism of the blockchain, the completed service content information provided by the service platform node device will not be tampered after being provided, thus ensuring the authenticity and completeness of the completed service content Security provides an effective data foundation for forensics or other applications based on the completed service content.
