The blockchain system comprises at least one blockchain node (only one is shown in fig. 1) of the access blockchain, and data such as generation record information of the query credential and the like are stored in the blockchain.
Specifically, the service client sends a data processing request to the corresponding service server in response to the service operation of the first user. The service server side determines service data to be verified of a first user about a target service according to the received data processing request; and sending a creation request of the verifiable assertion to the identity management system according to the determined service data. The identity management system creates a verifiable statement comprising the business data according to the received creation request, and sends a query certificate generation request to the blockchain system according to the verifiable statement. And after receiving the inquiry certificate generation request, the block chain nodes in the block chain system generate inquiry certificates capable of verifying the statement, and send the inquiry certificates to the service client of the first user through the identity management system and the service server. And the service client sends a query request to the identity management system according to the received query certificate, and the identity management system sends the queried verifiable statement to the service client. And the service client verifies the service data in the received verifiable statement according to the service data of the target service submitted by the first user. The block link node may further send the query credential to a service client (not shown in fig. 1) of the first user through the service server.
Further, as shown in fig. 2, the scenario may further include a query client of the first user, where the query client may be installed in a second terminal device, and the second terminal device may be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer, or the like (only the mobile phone is shown in fig. 2); the query client may be a stand-alone application or an applet embedded in another application. After receiving the query certificate, the service client provides the query certificate to the query client according to a preset mode and displays the obtained service data of the target service submitted by the first user; the query client sends a query request to the identity management system according to the obtained query certificate, receives the verifiable statement sent by the identity management system, and displays the received verifiable statement, so that the first user can perform matching processing on the service data in the verifiable statement and the service data displayed by the service client.
In the process, a verifiable statement is created based on the business data of the first user about the target business received by the business server, a query certificate of the verifiable statement is generated through the block chain system, and the query certificate is sent to the business client, so that the business client can obtain the verifiable statement based on the query certificate and verify the business data in the verifiable statement; therefore, the method and the device realize effective verification of the business data received by the business server, avoid the risk of loss of the first user due to falsification of the business data, and are beneficial to improving the effectiveness of on-line business handling; moreover, the query certificate is generated based on the block chain system, so that the authenticity of the query certificate and the unique relevance between the query certificate and the verifiable statement are ensured, the counterfeiting risk of the query certificate or the verifiable statement is avoided, and the verification effectiveness is further ensured.
Based on the application scenario architecture, one or more embodiments of the present application provide a data verification processing method. Fig. 3 is a flowchart illustrating a data verification processing method according to one or more embodiments of the present disclosure, where the method in fig. 3 can be executed by the identity management system in fig. 1, as shown in fig. 3, and the method includes the following steps:
step S102, receiving a request for creating a verifiable statement sent by a service server; the creating request is used for requesting to create a verifiable statement based on the business data of the first user about the target business received by the business server;
specifically, as shown in fig. 4, the service client sends a data processing request to the corresponding service server in response to the service operation of the first user. And the service server determines the service data of the first user about the target service to be verified according to the received data processing request, and sends a creation request of a verifiable statement to the identity management system according to the determined service data.
More specifically, when the first user has the handling requirement of the target service, the service client is operated to submit the service data of the target service; the service client side responds to the submitting operation of the first user, obtains the service data of the target service submitted by the first user, and sends a service processing request to the service server side according to the obtained service data. And the service server sends a request for creating a verifiable statement to the identity management system according to the service data in the received service processing request so as to realize the verification processing of the service data received by the service server. Therefore, before the business server performs the business processing, the business data received by the business server is verified, so that the effective processing of the target business can be ensured, and the loss of the first user caused by the falsification of the business data is avoided.
Or after the target service is handled, the first user operates the service client of the first user to select the target service to be verified so as to initiate verification processing in order to avoid tampering the service data in the transmission process or malicious tampering of the service data by the service server; the service client side responds to the verification operation of the first user, determines the service identification information of the first user about the target service to be verified, and sends a verification request to the service server side according to the service identification information. And the service server acquires corresponding service data according to the service identification information in the verification request, and sends a creation request capable of verifying a statement to the identity management system according to the acquired service data so as to verify the service data of the service server for performing service processing. The service identification information includes serial number information of the first user handling the target service, credential identification information of the first user about the service credential of the target service, and the like. Therefore, the verification processing is carried out after the business processing is finished, the problems that the business data is tampered and the like can be found in time, and the loss of the first user is avoided.
Step S104, creating a verifiable statement according to the creation request; wherein the content data of the verifiable assertion comprises business data;
step S106, sending a query certificate generation request to the blockchain system according to the verifiable statement, wherein the query certificate generation request is used for requesting the blockchain system to send the generated query certificate of the verifiable statement to a business client corresponding to the business server of the first user; and the inquiry certificate is used for the business client to obtain the verifiable statement and carry out verification processing on the business data in the obtained verifiable statement according to the business data of the target business submitted by the first user.
When the block chain system receives a query certificate generation request, a query certificate capable of verifying a statement is generated according to the query certificate generation request, the generated query certificate is sent to the identity management system, the identity management system sends the query certificate to the service server, and the service server sends the received query certificate to the service client. Or, the block chain system sends the generated query certificate to the service server, and the service server sends the received query certificate to the service client. The query certificate may include a hash value of a verifiable statement, and the specific form of the query certificate may be set by itself in practical application as needed, for example, the query certificate may be a two-dimensional code, a barcode, or the like.
In one or more embodiments of the present specification, a verifiable statement is created based on service data, which is received by a service server and relates to a target service, of a first user, and an inquiry credential of the verifiable statement is generated through a blockchain system, and the inquiry credential is sent to a service client, so that the service client can obtain the verifiable statement based on the inquiry credential and perform verification processing on the service data in the verifiable statement. Therefore, the method and the device realize effective verification of the business data received by the business server, avoid the risk of loss of the first user due to falsification of the business data, and are beneficial to improving the effectiveness of on-line business handling; moreover, the query certificate is generated based on the block chain system, so that the authenticity of the query certificate and the unique relevance between the query certificate and the verifiable statement are ensured, the counterfeiting risk of the query certificate or the verifiable statement is avoided, and the verification effectiveness is further ensured.
In order to ensure the validity of the verifiable claims, in one or more embodiments of the present application, the identity management system first verifies whether the creation request meets a preset creation condition, and specifically, the step S104 may include the following step S104-2:
and step S104-2, if the creation request is determined to meet the preset creation condition, creating a verifiable statement according to the creation request.
Determining that the creation request meets the preset creation condition may include: if the first digital identity information of the service server, the second digital identity information of the first user and the first signature data are obtained and the first signature data passes verification, determining that the creation request meets a preset creation condition; the first signature data is obtained by performing signature processing on the first specified data based on a first private key corresponding to the first digital identity information.
Specifically, when the service server and/or the first user applies for the digital identity information from the identity management system in advance, the creation request may include the first digital identity information of the service server and/or the second digital identity information of the first user, and when the service server and/or the first user does not apply for the digital identity information, the creation request may include the server information of the service server and/or the user information of the first user.

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 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.
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.
