In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. 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. 1, an execution main body of the method may be a terminal device, where the terminal device may be a computer device such as a notebook computer or a desktop computer, or may be a server, and the server may be an independent server, or a server cluster formed by multiple servers. The terminal device may be a device of a party that processes one or more services based on a block chain, and may specifically be a terminal device of a government affair service platform (which may include, for example, a web service platform, a right operation platform, a government affair service website, and the like), and the terminal device may provide multiple services, and may handle services corresponding to the services, such as an education service, a building service, a civil administration service, a qualification service, and the like, for a user. The method may specifically comprise the steps of:

in step S102, the electronic certificate information of the target user required by the service to be processed is determined according to the service to be processed of the target user.

Wherein the target user may be any user. The pending transaction may be a transaction requested (or required) by the target user, such as a transaction for querying bank account information, a transaction for handling one or more insurance items, and the like. The electronic document information may include electronic identity document information, electronic social security document information, electronic marriage document information, electronic public deposit document information, electronic driver license information, electronic driving license information, electronic passport information, and the like.

In practice, with the development of the internet and the mobile internet, information technologies such as computers, networks and communications are deeply influencing the social life and government operation modes. In order to innovate government affair working modes and improve administrative efficiency and service level, government affair organizations are generally pushing electronic certificates and full-process electronic registration management reform, public online application of the electronic certificates is promoted to handle administrative examination and approval business, and all levels of government affair organizations are promoted to carry out full-process electronic and networked application and the like.

The electronic certificate is a digital certificate conforming to the relevant technical specification and is a certificate information record formed, handled, transmitted and stored by electronic equipment such as a computer. The electronic certificate is not only the electronic form of the traditional paper certificate, but also the characteristics of the electronic data of the electronic certificate require reliable technical measures to ensure the authenticity and effectiveness of the electronic certificate, and the credible electronic certificate issuing and application management are realized.

The electronic certificate data can be stored in a business application system, and because various data are composed of basic data units and are easy to be falsified and forged in the computer interior and network transmission process, the authenticity and integrity of data telegraph text cannot be completely and effectively identified by various current identification means. Therefore, corresponding measures need to be taken to ensure the authenticity of the source and the integrity of the content of the license data in the electronic license service application system in the transmission process. The integrity of the content ensures that the electronic license data is not damaged by accidental or deliberate modification, forgery and the like in the process of being transmitted between the sender and the receiver.

In order to ensure the authenticity of the source and the integrity of the content of the license data in the electronic license service application system during the transmission process, embodiments of the present specification provide a technical solution, which may specifically include the following contents:

in daily life, many scenarios require the use of the user's personal certificate information to determine the user's identity or handle related services, and specifically, for a certain service or services, a service processor (or a service provider) may set a processing mechanism of the service according to the actual requirements of the service or services, that is, the service processor may set to execute service processing based on the user's electronic certificate information, and a user (i.e., a target user) requesting a certain service may request a service to be processed from the service processor. Before a target user needs to perform a certain service processing, the target user may specify a service to be processed to a service processing party, an application program for performing the service processing on the service to be processed may be installed in a terminal device of the service processing party, at this time, the service processing party may start the application program through the terminal device, the application program may be provided with related information of different services, after the service processing party selects the service to be processed, the terminal device may obtain the related information of the service to be processed (such as an identifier of the service), and may determine a service processing requirement of the service to be processed, and the like, according to the related information of the service to be processed.

Aiming at different services, different requirements may be met, and the different requirements may require different electronic certificate information of a target user, a corresponding relationship between different services (or service requirements) and an electronic certificate information identifier may be preset in a terminal device, the terminal device may search the electronic certificate information identifier corresponding to the service to be processed from the corresponding relationship based on the service to be processed of the target user, and may determine the searched electronic certificate information identifier as the electronic certificate information of the target user required by the service to be processed, or may input the relevant information of the service to be processed of the target user into a predetermined model (such as a classification model, etc.) for analysis to output a corresponding result (i.e. the electronic certificate information identifier), for example, the service to be processed of the target user requires the identity information of the target user, the electronic certificate information identifier corresponding to the service to be processed may be determined as identity certificate information based on a predetermined classification model, and for example, the social security certificate information of the target user is required to be used by the service to be processed of the target user, the electronic certificate information identifier corresponding to the service to be processed may be determined as a social security card based on the predetermined classification model.

In step S104, authorization and certification information of the electronic certificate information provided by the target user is acquired, and the authorization and certification information is used for granting the acquisition authority of the electronic certificate information to the service processing party of the service to be processed.

The authorization and certification information may be presented in various manners, for example, presented in an image code (including a barcode or a two-dimensional code, etc.) or presented in a notification message, which may be specifically set according to an actual situation, and this is not limited in this description embodiment.

In implementation, for a target user, the electronic certificate information of the target user includes personal privacy data of the target user, and in order to prevent any user from being able to freely acquire electronic certificate information of other users, rules for acquiring may be set for different electronic certificate information, for example, when another user acquires electronic certificate information of a certain user, authorization of the user needs to be passed, so as to ensure security of the electronic certificate information of the user being acquired or used.

After the terminal equipment of the service processing party determines the electronic certificate information of the target user required by the service to be processed, prompt information of the required electronic certificate information can be displayed to the service processing party. The service processing party can explain to the target user that the electronic certificate information of the target user is needed, or the service processing party can provide the prompt information to the target user. The target user may obtain the authorization and certification information of the electronic certificate information through the terminal device thereof, specifically, for example, the terminal device of the target user may store the authorization and certification information of different electronic certificate information in advance, at this time, the target user may obtain the authorization and certification information of the electronic certificate information from the authorization and certification information of different electronic certificate information stored in advance, and may provide the obtained authorization and certification information to the service processing party, or, the terminal device of the target user may install an application program for generating the authorization and certification information of different electronic certificate information, at this time, the target user may start the application program through the terminal device thereof, and may generate the authorization and certification information of the electronic certificate information through the application program, and the target user may provide the generated authorization and certification information to the service processing party.

The terminal device of the service processing party may include a mechanism or a device for acquiring the authorization and certification information of the target user, for example, if the authorization and certification information of the target user is presented in the form of an image code, the terminal device of the service processing party may include a scanning device of a graphic code, so that the service processing party may scan the authorization and certification information of the target user through the scanning device of the graphic code, thereby acquiring the authorization and certification information of the target user. If the authorization and certification information of the target user is presented in the form of a notification message, a processing mechanism of the notification message may be set in the terminal device of the service processing party, so that the service processing party may receive the notification message carrying the authorization and certification information of the target user, thereby obtaining the authorization and certification information of the target user.

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

The predetermined license database may include electronic certificate information of a plurality of different users, and may further include a plurality of different electronic certificate information of the same user, and data in the predetermined license database may be stored in a form of a table, which may be as shown in table 1.

TABLE 1

In practical application, the predetermined license database may also be specific to a certain type of electronic certificate information, for example, the predetermined license database only includes identity certificate information of a plurality of different users, and the like, which may be specifically set according to an actual situation, and this is not limited in this specification.

In implementation, the predetermined certificate database may be stored in the business processing party, or may be stored in a storage device of an organization or organization other than the business processing party. After obtaining the authorization certificate information of the target user, the terminal device of the service processing party may use the authorization certificate information to obtain the electronic certificate information corresponding to the authorization certificate information from the predetermined certificate database, for example, the authorization certificate information of the target user is used to obtain the identity certificate information 1 of the user a, and the terminal device may obtain the identity certificate information 1 of the user a corresponding to the authorization certificate information from the corresponding relationship in table 1.

In step S108, the verification information of the electronic certificate information is acquired from the blockchain, and the acquired electronic certificate information is verified according to the verification information.

The verification information may be information for verifying authenticity of the electronic certificate information, and the verification information may be determined in a variety of different manners, for example, the verification information may be obtained by processing the electronic certificate information through a specified algorithm, where the specified algorithm may be a specified encryption algorithm, a hash algorithm, and the like, and may be specifically set according to an actual situation, which is not limited in this specification.

In implementation, the block chain has been applied well to on-line data tamper resistance, anti-counterfeiting and traceability, and if relevant behavior data in the processes of using, managing, identifying and the like of the electronic certificate information is added to the block chain, the electronic certificate information cannot be changed and repudiated. Therefore, the related data of the electronic certificate information in the process can be maintained through the block chain, and all parties can check certain data based on the related data in the block chain, so that the accuracy of the electronic certificate information is guaranteed.

Therefore, an organization or a mechanism for constructing the preset certificate database can construct an electronic certificate storage industry platform and an electronic certificate application shared trust and credit system based on a block chain foundation platform. Corresponding certificate storages need to be generated in the application sharing process, the management process and the audit record of the electronic certificate, can be stored in an electronic certificate storage industry platform and then are uploaded to a block chain.

The block chain can provide basic service support for data tamper resistance of the electronic certificate, cross-regional electronic certificate mutual authentication and sharing, trusted certificate storage and source tracing verification of the certificate application, and a complete trust and credit system of the electronic certificate application is constructed. The application specification of the electronic certificate can be set in the block chain, and the specifications such as management certificate storage, application certificate storage, shared certificate storage, chain connection service, verification service and the like can be defined, so that the application and shared service of the electronic certificate and the guarantee are provided for a unified trust mechanism, application certificate storage chain connection, unified certificate storage specification, data tamper resistance and process traceability. The application systems in all areas and all fields can quickly verify the authenticity of the electronic certificate through a centralized block chain network and trace the whole process of generation, management and application of the electronic certificate.

The block chain may be a block chain constructed by a certificate data manager, a service processor (such as a government affair service platform), and the like, or a block chain constructed by a block chain of the certificate data manager and a block chain of the service processor, and the like. The blockchain may store verification information of the electronic certificate information of the target user, for example, a hash value of the electronic certificate information may be stored in the blockchain. The service processing side terminal device may acquire the verification information of the electronic certificate information of the target user from the blockchain based on the related information of the target user, may then calculate the verification information of the acquired electronic certificate information, may verify the acquired electronic certificate information based on the verification information acquired from the blockchain and the calculated verification information, may determine that the verification is passed if the verification information acquired from the blockchain is the same as the calculated verification information, and may determine that the verification is not passed if the verification information acquired from the blockchain is not the same as the calculated verification information.

In step S110, if the verification passes, the service to be processed is processed according to the electronic certificate information.

In implementation, the service processing corresponding to the service to be processed may be performed in various ways based on the electronic certificate information, for example, if the service to be processed is to change one or more items of information in the identity certificate information, the terminal device of the service processing party may determine the true identity of the target user according to the acquired identity certificate information, then, change one or more items of information in the identity certificate information of the target user based on the requirement of the target user, and upload the changed identity certificate information to the block chain. In practical applications, the specific manner by which the service processing corresponding to the target service is performed may be set according to practical situations, and this is not limited in the embodiments of this specification.

The embodiment of the specification provides a block chain-based service processing method, in which a service processing party acquires corresponding electronic certificate information from a predetermined certificate database through authorized certificate information of electronic certificate information provided by a target user, so that the electronic certificate information of the target user can acquire the use permission of the target user only after being authorized by the target user, the electronic certificate information of the target user is prevented from being stolen, in addition, after the electronic certificate information is acquired, the check information of the electronic certificate information is acquired from the block chain to check the acquired electronic certificate information, and corresponding service processing is performed after the check is passed, so that the authenticity of the electronic certificate information used in the service processing and the integrity of the information are ensured.

The terminal device may be a terminal device of a user requesting processing of a certain service or services, or the like. The method may specifically comprise the steps of:

in step S202, authorization certificate information of electronic certificate information required by the service to be processed is provided, so that the service processing party obtains the electronic certificate information from a predetermined certificate database according to the authorization certificate information, obtains verification information of the electronic certificate information from the block chain, verifies the obtained electronic certificate information according to the verification information, and executes service processing corresponding to the service to be processed according to the electronic certificate information when the verification passes, where the authorization certificate information is used to grant an acquisition right of the electronic certificate information to the service processing party of the service to be processed.

The authorization certification information can be presented in the form of an image code (including a bar code or a two-dimensional code, for example), or in the form of a notification message, for example.

In implementation, after the terminal device of the service processing party determines the electronic certificate information of the target user required by the service to be processed, the terminal device of the service processing party can display the prompt information of the required electronic certificate information to the service processing party. The service processing party can explain to the target user that the electronic certificate information of the target user is needed, or provide the prompt information to the target user. The terminal device of the target user can be installed with an application program for generating authorization and license information of different electronic certificate information, at this time, the target user can start the application program through the terminal device and generate authorization and license information (such as a bar code or a two-dimensional code) of the electronic certificate information through the application program, and the target user can provide the generated authorization and license information to the service processing party.

In step S204, the relevant behavior data providing the authorization and certification information is uploaded to the blockchain.

In practical applications, the related behavior data may further include other data besides the data, which may be determined according to practical situations, and this is not limited in this embodiment of the present specification.

In implementation, in order to keep a corresponding certificate or evidence for each authorization certificate of a user for verifying the use and processing of corresponding electronic certificate information in the following, the terminal device of a target user may record time and location information in the process of providing the authorization certificate information, and related information of a service processing party and related data of a service to be processed, operation behavior data in the process of obtaining or generating the authorization certificate information by the target user, and operation behavior data of the target user in the process of providing the authorization certificate information, and the like, and may send the recorded related behavior data to a block chain node. In practical application, the relevant behavior data in the process may send the information to the blockchain node, and may also send other relevant information to the blockchain node, which may be specifically set according to an actual situation, and this is not limited in this specification.

The embodiment of the specification provides a block chain-based service processing method, in which a service processing party acquires corresponding electronic certificate information from a predetermined certificate database through authorized certificate information of electronic certificate information provided by a target user, so that the electronic certificate information of the target user can acquire the use permission of the target user only after being authorized by the target user, the electronic certificate information of the target user is prevented from being stolen, in addition, after the electronic certificate information is acquired, the check information of the electronic certificate information is acquired from the block chain to check the acquired electronic certificate information, and corresponding service processing is performed after the check is passed, so that the authenticity of the electronic certificate information used in the service processing and the integrity of the information are ensured. In addition, the target user also needs to upload the related behavior data providing the authorization and certification information to the blockchain, so as to store the authorization behavior of the target user, and prevent the uploaded data from being tampered by the blockchain, thereby ensuring the credibility of the stored data.

EXAMPLE III

As shown in fig. 3, an embodiment of the present disclosure provides a service processing method based on a block chain, where an execution main body of the method may be a block chain node, where the block chain node may be a computer device such as a notebook computer or a desktop computer, or may also be a server, and the server may be an independent server, or a server cluster formed by multiple servers, or the like. The method may specifically comprise the steps of:

in step S302, behavior data related to authorization and usage information of electronic certificate information required by a target user to provide a service to be processed is acquired and stored in a block chain; the authorization certificate information is used for granting the acquisition authority of the electronic certificate information to a service processing party of the service to be processed.

In implementation, after a target user provides authorization and certification information of electronic certificate information required by a service to be processed, the target user can actively upload related behavior data of the authorization and certification information of the electronic certificate information required by the service to be processed to a block chain node through terminal equipment of the target user, and the block chain node can correspondingly store the related behavior data and the related information of the electronic certificate information of the target user or identification of the target user, so that the related behavior data is stored in the block chain. Or after detecting the authorization and certification information of the electronic certificate information required by the to-be-processed service provided by the target user, the block chain link point requests the terminal equipment of the target user to upload the related behavior data so as to store the related behavior data in the block chain.

In step S304, the related behavior data in the electronic certificate information used by the service processing party is acquired and stored in the block chain, where the related behavior data in the electronic certificate information is used in the process of performing service processing on the service to be processed.

The related behavior data of the service processing party using the electronic certificate information may include various types, such as time and location information of the service processing party using the electronic certificate information, related information of the service processing party (such as name or organization code of the service processing party) and related data of the service to be processed (such as name or code of the service to be processed), and the like. In practical applications, the related behavior data may further include other data besides the data, which may be determined according to practical situations, and this is not limited in this embodiment of the present specification.

In implementation, in the process of performing service processing on the service to be processed, the terminal device of the service processing party may record behavior data related to the electronic certificate information in the process of performing service processing on the service to be processed, and then may upload the behavior data related to the electronic certificate information to a block chain node, where the block chain node may store the behavior data related to the electronic certificate information in correspondence with the related information of the electronic certificate information of the target user or the identifier of the target user, so that the related behavior data is stored in the block chain.

The electronic certificate information can be encrypted in various ways, and specifically can be implemented by setting a corresponding encryption algorithm, for example, a certificate data manager can encrypt the electronic certificate information through a hash algorithm to obtain a hash value corresponding to the electronic certificate information. The calculated hash value can be uploaded to a blockchain node, and the blockchain node can store the hash value of the electronic certificate information in a blockchain.

In addition, considering that there may be different file data for different users, for example, an image file or a scanned file of an identity card of a certain user, for the file data, the block link node may obtain verification information of the file data of the target user provided by the license data manager, and store the verification information in the block chain.

The verification information may be information for verifying authenticity of the file data, and the verification information may be determined in a variety of different manners, for example, the verification information may be obtained by processing the file data through a specified algorithm, where the specified algorithm may be a specified encryption algorithm, a hash algorithm, and the like, and may be specifically set according to an actual situation, which is not limited in this specification.

After the electronic certificate information of the user and the related file data are processed in the above manner and uploaded to the blockchain in an encryption manner, the electronic certificate information of the target user, the authentication and management of the electronic certificate information, and the like can be stored, which can be specifically referred to the processing of step S404 to step S426 below.

The foregoing description has been directed to specific embodiments of this disclosure. 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 Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (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.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable blockchain-based business processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable blockchain-based business processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
