Obviously, the described The embodiments are only a part of the embodiments in this specification, rather than all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this specification.

Example one

As shown in Figure 1, the embodiment of this specification provides a blockchain-based business processing method. The execution subject of the method can be a terminal device, where the terminal device can be a computer device such as a laptop or a desktop computer, or It is a server, etc. The server can be an independent server or a server cluster composed of multiple servers. The terminal device can be a device of a party that processes a certain one or more businesses based on the blockchain, such as a terminal device of a government service platform (which may include, for example, a network communication platform, a power operation platform, a government service website, etc.) , The terminal device can provide a variety of services, and can handle services corresponding to each service for users, such as education services, housing construction services, civil affairs services, and practicing qualification services. The method may specifically include the following steps S102 to S110.

In step S102, the electronic credential information of the target user required for the service to be processed is determined according to the service to be processed of the target user.

Among them, the target user can be any user. The business to be processed may be a business requested (or required) by a target user, such as a business to query bank account information, a business to handle one or more insurances, and so on. Electronic certificate information may include electronic identity certificate information, electronic company guarantee certificate information, electronic marriage certificate information, electronic provident fund certificate information, electronic driver's license information, electronic driving license information, and electronic passport information, etc.

In the implementation, with the development of the Internet and mobile Internet, information technology based on computers, networks, and communications is profoundly affecting social life and the way government affairs operate. In order to innovate government work models and improve administrative efficiency and service levels, government agencies are generally implementing electronic certificates and full-process electronic registration management reforms, promoting the online application of electronic certificates to the public for administrative approval services, and promoting government agencies at all levels to carry out full-process digitalization , Networked applications, etc.

An electronic license is a digital license that complies with relevant technical specifications. It is a record of license information formed, processed, transmitted, and stored by computers and other electronic equipment. Electronic licenses are not only the electronic form of traditional paper licenses, but the characteristics of their own electronic data require the use of reliable technical measures to ensure their authenticity and effectiveness, and to achieve credible electronic license issuance and application management.

Electronic certificate data can be stored in the business application system. Because all kinds of data are composed of basic data units in the computer and network transmission process and are easily tampered with and forged, the current various authentication methods cannot fully identify effectively. The authenticity and integrity of data messages. Therefore, it is necessary to take corresponding measures to ensure the authenticity of the source and the integrity of the content of the license data in the electronic license business application system during the transmission process. Among them, the integrity of the content is to ensure that the electronic certificate data is not accidentally or deliberately modified or forged during the transfer process between the sender and the receiver.

In order to ensure the authenticity of the source of the license data in the transmission process and the integrity of the content in the electronic license business application system, the embodiment of this specification provides a technical solution, which may specifically include the following content.

In daily life, many scenarios need to use the user’s personal certificate information to determine the user’s identity or handle related services. Specifically, for one or more services, the service processor (or service provider) can The actual needs of the one or more services set the processing mechanism of the above-mentioned services, that is, the business processor can set to perform business processing based on the user’s electronic certificate information, and the user requesting a certain business service (that is, the target user) can request the business processor Request pending services. Before the target user needs to process a certain business, the target user can explain the pending business that needs to be processed to the business processor. The terminal device of the business processor can be installed with an application for business processing of the business to be processed. At this time, the business The processor can start the application through the terminal device, and the application can be set with relevant information of different services. When the service processor selects the service to be processed, the terminal device can obtain the relevant information of the service to be processed (such as the identifier of the service). Etc.), and can determine the business processing requirements of the to-be-processed business and so on based on the relevant information of the to-be-processed business.

Different services may have different requirements, and different requirements may require different electronic credential information of the target user. The corresponding relationship between different services (or business requirements) and the electronic credential information identification can be preset in the terminal device. The terminal device can find the electronic credential information identifier corresponding to the business to be processed from the above-mentioned corresponding relationship based on the business to be processed of the target user, and can determine the electronic credential information identified as the electronic credential of the target user required by the business to be processed Information, or, you can also input the relevant information of the target user's pending business into a predetermined model (such as a classification model, etc.) for analysis to output the corresponding result (ie, electronic certificate information identification), for example, the target user's pending transaction If the business needs to use the ID information of the target user, it can be determined based on the predetermined classification model that the electronic credential information corresponding to the service to be processed is identified as ID information. For another example, the target user’s social security certificate information needs to be used for the service to be processed , It is determined based on a predetermined classification model that the electronic certificate information corresponding to the business to be processed is identified as a social security card, etc.

In step S104, the authorization certificate information of the electronic certificate information provided by the target user is obtained, and the authorization certificate information is used to grant the business processor of the service to be processed the right to obtain the electronic certificate information.

Among them, the authorization information can be presented in a variety of ways, for example, in the form of image codes (including barcodes or QR codes, etc.) or in the form of notification messages, etc., which can be set according to actual conditions. The embodiment does not limit this.

In the implementation, for the target user, the target user’s electronic certificate information includes the target user’s personal privacy data. In order to prevent any user from being able to obtain other users’ electronic certificate information at will, the acquisition can be set for different electronic certificate information. For example, when other users obtain the electronic certificate information of a certain user, they need to be authorized by the user, so as to ensure the security of the user's electronic certificate information being obtained or used.

After the terminal device of the business processor determines the electronic credential information of the target user required by the business to be processed, it can display the prompt information that the electronic credential information is needed to the business processor. The business processor can explain to the target user that the electronic certificate information of the target user is needed, or the business processor can provide the aforementioned prompt information to the target user. The target user can obtain the authorization certificate information of the electronic certificate information through its terminal device. For example, the target user's terminal device can pre-store the authorization certificate information of different electronic certificate information. At this time, the target user can download the authorization certificate information from the pre-stored electronic certificate information. In the authorization certificate information of different electronic certificate information, the authorization certificate information of the electronic certificate information can be obtained, and the obtained authorization certificate information can be provided to the business processor, or the terminal device of the target user can be installed with the generator The application program of the authorization certificate information of different electronic certificate information. At this time, the target user can start the application program through his terminal device, and can generate the authorization certificate information of the electronic certificate information through the application program, and the target user can generate The authorized license information is provided to the business processor.

The terminal equipment of the service processor may include a mechanism or equipment for obtaining the authorization information of the target user. For example, if the authorization information of the target user is presented in the form of an image code, the terminal equipment of the service processor may A scanning device including a graphic code, so that the service processor can scan the authorization certificate information of the target user through the scanning device of the graphic code, thereby obtaining the authorization certificate information of the target user. If the authorization certificate information of the target user is presented in the form of a notification message, the terminal device of the service processor can be provided with a processing mechanism for the notification message, so that the service processor can receive the authorization certificate information carrying the target user The notification message to obtain the authorization information of the target user.

In step S106, the corresponding electronic certificate information is obtained from the predetermined certificate database according to the above-mentioned authorization certificate information.

Among them, the predetermined license database may include multiple electronic certificate information of different users, and the predetermined license database may also include multiple different electronic certificate information of the same user, and the data in the predetermined license database may be stored in the form of a table. , Can be as shown in Table 1.

Table 1

For example, the verification can be obtained by processing the electronic credential information through a specified algorithm. Information, the specified algorithm may be a specified encryption algorithm, hash algorithm, etc., which can be specifically set according to actual conditions, which is not limited in the embodiment of this specification.

In the implementation, the blockchain has been well applied in the direction of anti-tampering, anti-counterfeiting and traceability of online data. If the relevant behavioral data in the use, management and identification of electronic certificate information is added to the blockchain , Then the electronic certificate information will not be able to be changed and denied. Therefore, the relevant data of the electronic certificate information in the above process can be maintained through the blockchain, so that all parties can verify certain data based on the relevant data in the blockchain to ensure the accuracy of the electronic certificate information.

To this end, the organization or institution that plans to build the license database can build an electronic license storage industry platform based on the blockchain basic platform, and build a trust and credit system for electronic license application sharing. The application sharing process, management process and audit records of electronic certificates need to generate corresponding deposit certificates, which can be stored in the electronic certificate deposit industry platform and then uploaded to the blockchain.

Blockchain can provide basic service support for the tamper-proof data of electronic certificates, cross-regional mutual recognition and sharing of electronic certificates and certificates, and the credible storage and traceability verification of certificate applications, and build a complete trust and credit system for electronic certificates and certificates. The application specifications of electronic certificates can be set in the blockchain, and specifications such as management deposits, application deposits, shared deposits, on-chain services, verification services, etc. can be defined, which are the application and sharing services of electronic certificates and certificates, and are unified trust Mechanisms, application deposits on the chain, unified deposit specifications, data anti-tampering, and process traceability provide guarantees. Application systems in various regions and fields can quickly verify the authenticity of electronic certificates and trace the entire process of electronic certificate generation, management, and application through a centralized blockchain network.

The blockchain can be a blockchain jointly established by license data managers and business processors (such as government service platforms, etc.), or it can be composed of license data managers' blockchains and business processors' blockchains, etc. The built blockchain. The verification information of the electronic certificate information of the target user may be stored in the blockchain. For example, the hash value of the electronic certificate information may be stored in the blockchain. The terminal device of the business processor can obtain the verification information of the target user’s electronic credential information from the blockchain based on the relevant information of the target user, and then can calculate the verification information of the acquired electronic credential information, which can be based on the block chain The verification information obtained in the chain and the verification information calculated above are verified. If the verification information obtained from the blockchain is the same as the verification information calculated above, the verification can be determined Pass, if the verification information obtained from the blockchain is not the same as the verification information calculated above, it can be determined that the verification has not passed.

In step S110, if the verification is passed, the business to be processed is processed according to the above-mentioned electronic certificate information.

In implementation, it is possible to implement business processing corresponding to the business to be processed based on the above-mentioned electronic certificate information in a variety of ways. For example, if the business to be processed is to change one or more pieces of information in the identity document information, the terminal of the business processor The device can determine the true identity of the target user based on the acquired ID information, and then can modify one or more of the target user’s ID information based on the target user’s requirements, and can change the changed ID information Upload to the blockchain. The foregoing is only a feasible business processing method. In practical applications, the specific method for performing business processing corresponding to the target business can be set according to the actual situation, which is not limited in the embodiment of this specification.

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), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description), etc., currently most commonly used It is 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. Examples of controllers include but are not limited to the following microcontrollers: ARC625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicon Labs C8051F320, the memory controller can also be implemented as part of the memory control logic. Those skilled in the art also know that, in addition to implementing the controller in a purely computer-readable program code manner, it is entirely possible to program the method steps to make the controller use logic gates, switches, application specific integrated circuits, programmable logic controllers and embedded The same function can be realized in the form of a microcontroller, etc. 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.
