All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.

Example one

As shown in fig. 1A and fig. 1B, an embodiment of the present disclosure provides a service processing method based on a blockchain, where an execution main body of the method may be a blockchain system, and the blockchain system may be composed of a terminal device or a server, where the terminal device may be a mobile terminal device such as a mobile phone and a tablet computer, and may also be a device such as a personal computer. The server may be an independent server, a server cluster including a plurality of servers, or the like. The system architecture related to the embodiments of the present specification may be as shown in fig. 2, which includes a terminal device of a target user, a device of a first service party, a device of a second service party, and a block chain. As shown in fig. 1A and 1B, the method may specifically include the following steps:

In step S102, an identity authentication request of a target user sent by a first service party is received, where the identity authentication request is sent by the first service party when receiving a service processing request of a target service provided by the target user, the identity authentication request includes a user identifier of the target user, and the service processing request includes service data provided by the target user and directed to the target service.

The first business party may be a party that provides a certain business to the user and processes the business requested by the user, for example, a financial institution, specifically, a certain bank or a certain financial enterprise. The target user may be any user, and in this embodiment, the target user may be a user who initiates a certain specified service. The target service may be a service requested by a user, and in practical applications, the target service may include multiple services, such as an asset mortgage service (specifically, a house mortgage service, etc.), a notary service, or the like. The user identifier may be a name, an IDentity card number, or the like of the target user, or may be information that is obtained by calculation based on the above information and that can uniquely determine the IDentity of the target user, or may also be information that is set for the target user based on the block chain and that can be represented in a variety of different ways, and in practical applications, the digital IDentity information may be represented by a Decentralized IDentity (didn), where the DID may be a Decentralized verifiable digital identifier, and has the characteristics of being distributed, autonomously controllable, and multiplexed across chains (across block chains). The service data may be data related to processing a target service, and the corresponding service data may be different for different target services.

In practice, information security based on the internet is an important subject of attention of each institution (particularly financial institution), for some businesses, information transmission of the internet often needs to pass through a plurality of participants, and the information passes through the information of the plurality of participants, so that the credibility and information security face a great test, for example, real estate mortgage business such as house is a traditional offline business, the business involves a plurality of participants such as bank or financial institution, real estate registration center, assessment institution, court, arbitration institution and court, wherein the real estate mortgage registration is one of the most important links, and currently, many banks (or financial institutions) and government institutions start to try to provide online real estate mortgage registration service, and at present, the common mode is that a bank system directly connects to the real estate registration center, and a user initiates a mortgage registration application to the real estate registration center through the bank (or financial institution), during the period, the bank (or the financial institution) verifies the identity of the user and the intention of the real estate mortgage registration of the user, however, the real estate registration center is difficult to completely trust the confirmation of the identity of the user and the intention of the real estate mortgage registration of the user by the bank (or the financial institution), and is also inconvenient to repeatedly initiate the verification of the identity and the intention of the real estate mortgage registration to the user, so that the problems of information security and information authenticity can be avoided, and for this reason, a processing scheme which does not need to repeatedly verify the identity and the intention of the real estate mortgage registration of the user needs to be provided. The embodiment of the present specification provides a technical solution, which may specifically include the following contents:

With the rapid development of electronic commerce, a large number of organizations or enterprises are more and more inclined to perform service communication and communication in an electronic information manner to reduce cost and improve competitiveness, and for a target service, when a target user requests a first service party to perform service processing of the target service, a terminal device of the target user may obtain relevant information provided by the target user requesting the target service (a specific processing procedure may be that the target user obtains a processing entry or a relevant page of the target service through the terminal device, and may enter an information providing page of the target service through the processing entry or the relevant page, the information providing page may include one or more information items, each information item corresponds to an information input box, and the target user may input information corresponding to the corresponding information item in the information input box in the information providing page, the input information may be related information provided by the target user requesting the target service, where the related information may include service data of the target service, and the like). After receiving the service processing request, the first service party may determine that the target user needs to be authenticated, and in addition, in order to improve the credibility of the target user authentication, a blockchain system may be provided, where a blockchain is essentially a decentralized database, and is a series of data blocks associated by using a cryptographic method, and each data block may contain stored data and related information thereof (e.g., information that may be used to verify the validity (or anti-counterfeiting property) of the data and generate a next block, etc.). The block chain can be well applied to the on-line data tamper-proofing, anti-counterfeiting and traceable directions, and if the use and management of the information related to the target service processing are added into the block chain system, the related information and the processing process data cannot be changed and repudiated. Therefore, data related to the target service may be maintained through the blockchain system, and thus, a plurality of processing mechanisms may be set in the blockchain system to perform service processing on the target service, specifically, the first service party may obtain information such as a user identifier of the target user, and may generate an identity authentication request of the target user based on the information, and may send the identity authentication request of the target user to the blockchain system (e.g., a blockchain node in the blockchain system), and the blockchain system may receive the identity authentication request of the target user sent by the first service party.

It should be noted that the blockchain system may be provided with an intelligent contract, and the set intelligent contract may be deployed in the blockchain system. The blockchain system may perform business processing of the target business based on the intelligent contract, as in the above processing, the blockchain system may receive an identity authentication request of the target user sent by the first business party based on the corresponding intelligent contract.

In step S104, a terminal device for performing identity authentication is determined based on an intelligent contract and a user identifier pre-deployed in the block chain system, and an identity authentication request of a target user is sent to the terminal device, so that the terminal device authenticates the identity of the target user to obtain a corresponding authentication result, and the intelligent contract is used to trigger identity authentication of a user initiating a target service and process the target service based on the authentication result of the identity authentication.

In implementation, one or more different intelligent contracts may be pre-deployed in the blockchain system, and different intelligent contracts may execute different service processing processes, and then, related data of different service processing mechanisms may be set in the different intelligent contracts, so that, after the blockchain system receives an identity authentication request of a target user sent by a first service party, a pre-deployed intelligent contract related to the target service may be obtained, and the obtained intelligent contract may be an intelligent contract for triggering identity authentication of a user who initiates the target service and processing the target service based on an authentication result of the identity authentication. The block chain system may determine, based on the acquired intelligent contract and the user identifier of the target user in the identity authentication request, a terminal device that needs to be subjected to identity authentication, where the determined terminal device may be a terminal device used by the target user corresponding to the user identifier, and the terminal device may be a device such as a mobile phone, a tablet computer, a personal computer, or the like. Then, the blockchain system may send an identity authentication request of the target user to the determined terminal device, and after receiving the identity authentication request of the target user, the terminal device may authenticate the identity of the target user, specifically, after receiving the identity authentication request of the target user, the terminal device may drive a preset identity authentication process, for example, the terminal device may start a face recognition mechanism or a fingerprint recognition mechanism, and may prompt the target user to input face data or fingerprint data of the target user, the target user may input the face data or fingerprint data of the target user into the terminal device, the terminal device may receive the face data or fingerprint data input by the target user, and may compare the face data or fingerprint data input by the target user with the face data or fingerprint data of the target user stored in advance, respectively, if the two are the same or the similarity value between the two is greater than the preset similarity threshold, the identity authentication of the target user can be determined to be passed, otherwise, the identity authentication of the target user can be determined to be failed, at this time, the terminal device can input corresponding prompt information to prompt the target user that the identity authentication is failed, re-authentication can be performed, and the like. Through the above processing procedure, the terminal device can determine the authentication result of the identity authentication of the target user.

In step S106, the authentication result is obtained based on the intelligent contract, and if the authentication result is passed, the service data of the target service sent by the first service party is received, and the authentication result and the service data of the target service are sent to the second service party, so as to perform registration processing on the service data of the target service of the target user.

In implementation, the blockchain system acquires a corresponding authentication result from the determined terminal device by invoking the intelligent contract, specifically, the blockchain system may invoke the intelligent contract to determine information related to the terminal device performing identity authentication, and then may send an acquisition request of the authentication result to the terminal device, and after receiving the acquisition request of the authentication result, the terminal device may send the authentication result to the blockchain system. The block chain node can analyze the obtained authentication result by calling the intelligent contract, if the obtained authentication result is determined to be passed, the identity of the target user is correct, at the moment, subsequent related processing can be continuously executed, namely, the first service direction can be triggered to send the service data of the target service to the block chain system, at the moment, the first service direction can send the service data of the target service to the block chain system, the block chain system can receive the service data of the target service sent by the first service direction, and the block chain system can confirm the obtained service data and the identity authentication result of the target user, so that the accuracy and the safety of the service data and the identity authentication result of the target user are ensured. Then, the blockchain system may send the authentication result and the service data of the target service to a second service party, and after receiving the authentication result and the service data of the target service provided by the blockchain system, the second service party may determine that the data provided by the blockchain system is accurate, safe and trusted, and at this time, the second service party may perform registration processing on the service data of the target service of the target user, thereby ensuring that the data registered and processed by the second service party is accurate, safe and trusted.

The embodiment of the specification provides a service processing method based on a block chain, which includes sending an identity authentication request of a target user to a block chain system when a first service party receives a service processing request of the target service provided by the target user, wherein the identity authentication request includes a user identifier of the target user, the service processing request includes service data provided by the target user and aiming at the target service, then, determining a terminal device for performing identity authentication based on an intelligent contract and the user identifier pre-deployed in the block chain system, and sending the identity authentication request of the target user to the terminal device, so that the terminal device authenticates the identity of the target user to obtain a corresponding authentication result, further receiving the service data of the target service sent by the first service party, and sending the authentication result and the service data of the target service to a second service party, the method is used for registering the service data of the target service of the target user, and the identity authentication result is transferred in a decentralized manner by the block chain system, so that the authentication result is prevented from being forged in the transfer process, and meanwhile, the authentication result can not be falsified after being stored on the block chain system, the accuracy of the mortgage service is greatly improved, and the block chain system is used for achieving credible consensus on the result of the user identity authentication among all parties, and any person or mechanism can not forge and modify the authentication result in a unilateral way, so that the service credibility is enhanced, and the repeated authentication is reduced.

Example two

As shown in fig. 3, an execution main body of the method may be a blockchain system, and the blockchain system may be composed of a terminal device or a server, where the terminal device may be a mobile terminal device such as a mobile phone or a tablet computer, and may also be a device such as a personal computer. The server may be an independent server, a server cluster including a plurality of servers, or the like. The method may specifically comprise the steps of:

in step S302, an identity authentication request of a target user sent by a first service party is received, where the identity authentication request is sent by the first service party when receiving a service processing request of a target service provided by the target user, the identity authentication request includes a user identifier of the target user, and the service processing request includes service data provided by the target user and directed to the target service.

For a specific processing procedure of step S302, reference may be made to relevant contents in the first embodiment, which is not described herein again.

In step S304, a terminal device for identity authentication is determined based on the smart contract and the user identifier pre-deployed in the blockchain system.

In implementation, a correspondence between a user identifier and a device identifier of a terminal device may be stored in advance in the block chain system, where the device identifier may include multiple types, for example, an IMEI number or an MAC address of the terminal device. After the block chain system acquires the user identifier, the device identifier corresponding to the user identifier can be searched in the corresponding relationship which is stored in advance through the intelligent contract, if the corresponding device identifier is not searched in the corresponding relationship, it is indicated that the device identifier is not stored in the block chain system, at this moment, it can be determined that the terminal device of the target user is not registered in the block chain system, in order to prevent other users from stealing the account information of the target user for service processing, a reminding message can be sent to the terminal device of the target user through the intelligent contract to remind the target user that the account of the target user may have risks, and if the target user determines that the device identifier is accurate, the processing can be continued through the intelligent contract. If the corresponding device identifier can be found in the corresponding relationship through the intelligent contract, the terminal device corresponding to the found device identifier can be determined to be the terminal device needing identity authentication.

In practical applications, the identity authentication request may include a digital identity information file of the target user, where the digital identity information file records digital identity information of the target user, and the digital identity information of the target user is used as the user identifier, where the digital identity information may refer to information that can be drawn by identifying the user through digital information, that is, information that is expressed in a form of concentrating real identity information into digital codes, so as to bind, query, and verify real-time behavior information of the user. The digital identity information may not only include the birth information, individual description, biological characteristics and other identity code information of the seed user, but also relate to personal behavior information (such as transaction information or entertainment information) with various attributes and the like. The digital Identity information may be presented in various ways, such as DID (Decentralized Identity) and the like. For the case that the digital identity information is DID, in practical application, the DID of the target user may include a DID Document (such as DID Document), and the target user may preset the digital identity information of the target user in the DID Document to serve as the user identifier of the target user.

Based on the actual situation of the user identifier, the process of determining the terminal device for identity authentication based on the smart contract and the user identifier pre-deployed in the blockchain system in step S104 may refer to the following processes of step a2 and step a 4.

In step a2, a digital identity information file of the target user is obtained, and the digital identity information of the target user is obtained from the digital identity information file.

In implementation, after the block chain system obtains the user identifier, the digital identity information file of the target user may be obtained in the block chain system, and the digital identity information of the target user may be extracted from the digital identity information file, for example, if the digital identity information of the target user is DID, the digital identity information file may be DID Document, the block chain system may obtain the DID Document of the target user, the DID Document of the target user may be recorded in the DID Document, and at this time, the block chain system may extract the DID of the target user from the DID Document.

In step a4, if the digital identity information of the target user in the digital identity information file matches the user identifier, determining a terminal device for performing identity authentication based on the smart contract pre-deployed in the blockchain system and the digital identity information of the target user.

In implementation, after the digital identity information of the target user is extracted from the digital identity information file in the manner described above, the extracted digital identity information may be matched with the user identifier, and if the extracted digital identity information is matched with the user identifier, it may be determined that the user identifier of the target user is accurate.

In step S306, an identity authentication request is sent to the terminal device through the third party authority, so that the terminal device authenticates the identity of the target user to obtain a corresponding authentication result.

The foregoing description of specific embodiments has been presented for purposes of illustration and description. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
