It should be understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the present application, and are not intended to limit the scope of the present application in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As will be appreciated by one skilled in the art, embodiments of the present application may be embodied as a system, apparatus, device, method or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
Considering the existing data query application based on the blockchain, if some sensitive information or information which is not allowed to be displayed appears when commodity information is queried on the chain, the extremely serious influence on the public and the society is caused, and how to process the sensitive information on the blockchain becomes a problem which needs to be solved urgently by each blockchain platform at present. In view of the above problems, if a system similar to the conventional information recognition filtering system is built on a chain, a keyword library needs to be stored on the chain, and the keyword library is matched for filtering when data is queried on the chain, but it is basically not feasible to do so: 1) the key word library on the chain has higher maintenance cost; 2) the intelligent contracts lack a plurality of class libraries of common programming languages (such as various operation methods based on character strings), and need to write special contract methods, so that the difficulty is high; 3) even if a similar method is written, the performance of recognition and filtering on the chain is a problem (only basic traversal can be performed, word segmentation cannot be performed, indexes cannot be built, and the like), and the query experience of a user is directly influenced by the fact that the keyword library is slightly large. Therefore, the inventors thought that the above problem could be solved by performing information recognition by a server under the link, and performing on-link processing on a target object including key information.
Based on the above problems, embodiments of the present application provide a data processing method. Fig. 1 shows an application scenario of the data processing method provided in the embodiment of the present application. The screening server can send a data synchronization request to the blockchain system; the blockchain system responds to the received request and returns the characteristic information of the target object to the screening server; the screening server determines whether the characteristic information contains preset key information or not, and sends a processing request to the blockchain system under the condition that the characteristic information contains the preset key information; and the block chain system responds to the processing request to process the target object with the characteristic information containing the preset key information. The user terminal may send a data query request to the blockchain system, and the blockchain system returns corresponding information to the user terminal in response to the data query request.
The screening server is a server independent of the blockchain system, that is, the screening server is not a part of the blockchain system, and the screening server may be a single server, a server cluster, or a cloud server, and the specific components form the present application without limitation. The user side may be a desktop computer, a notebook, a mobile phone terminal, a PDA, etc., and any device that can display content and receive operation instructions to a user or a service person may be used, and the present application is not limited to the formation of the user side.

Although the present application provides method operational steps or apparatus configurations as illustrated in the following examples or figures, more or fewer operational steps or modular units may be included in the methods or apparatus based on conventional or non-inventive efforts. In the case of steps or structures which do not logically have the necessary cause and effect relationship, the execution sequence of the steps or the module structure of the apparatus is not limited to the execution sequence or the module structure described in the embodiments and shown in the drawings of the present application. When the described method or module structure is applied in an actual device or end product, the method or module structure according to the embodiments or shown in the drawings can be executed sequentially or executed in parallel (for example, in a parallel processor or multi-thread processing environment, or even in a distributed processing environment).
Specifically, as shown in fig. 2, a data processing method provided by an embodiment of the present application may include the following steps:
in step S201, the screening server obtains feature information of the target object stored in the blockchain system.
The method comprises the steps that feature information of a plurality of target objects is stored in a blockchain system, and in order to determine whether the feature information of each target object contains preset key information, the feature information of the target objects stored in the blockchain system is acquired through a screening server.
Further, in some embodiments of the present application, the acquiring, by the screening server, the feature information of the target object stored in the blockchain system may include: the screening server initiates a data synchronization request to the blockchain system; the screening server receives characteristic information of the target object returned by the blockchain system in response to the data synchronization request.
Specifically, in some embodiments of the present application, the characteristic information may include, but is not limited to, at least one of: identification information, name information, description information, logistics information, brand information, and production information. The identification information is a unique identification of the target object, and may be a two-dimensional code, a barcode, a character string, and the like. The production information may include information such as a production address, a production date, and a production manufacturer.
In step S202, the screening server determines whether preset key information exists in the feature information.
Specifically, after acquiring the feature information of a plurality of target objects stored in the blockchain system, the screening server needs to determine whether preset key information exists in the feature information of each target object one by one. The preset key information may be preset keyword information, preset picture information, and the like. Whether preset key information exists in the feature information or not is determined by the screening server, so that the maintenance cost of the key information can be reduced, the determination difficulty is reduced, and the processing speed is increased. The preset key information may specifically be preset sensitive information, for example, may be information that is specified and cannot be displayed and presented.
In order to determine whether the feature information includes preset key information, a preset data list may be stored in the screening server, where a plurality of preset key information are stored in the preset data list. Therefore, in some embodiments of the present application, the determining, by the screening server, whether preset key information exists in the feature information may include: the screening server calls a preset data list, wherein a plurality of preset key information are stored in the preset data list; the screening server compares the characteristic information with a plurality of preset key information in the data list one by one; under the condition that at least one piece of key information in a plurality of pieces of preset key information exists in the feature information, the screening server determines that the preset key information exists in the feature information; and under the condition that any one of a plurality of pieces of preset key information does not exist in the feature information, the screening server determines that the preset key information does not exist in the feature information.
In addition, in order to determine whether preset key information exists in the feature information, a screening server can be used for calling a recognition server to recognize the feature information, wherein a preset data list is stored in the recognition server, and a plurality of preset key information are stored in the preset data list. Therefore, in some embodiments of the present application, the determining, by the screening server, whether preset key information exists in the feature information may include: the screening server sends an identification request to an identification server, wherein the identification request carries characteristic information of a target object; the screening server receives a recognition result returned by the recognition server in response to the recognition request; and the screening server determines whether preset key information exists in the characteristic information according to the identification result. The identification result comprises an identification result passing identification and an identification result failing identification. Under the condition that the identification result is that the identification is passed, the screening server determines that the characteristic information of the target object does not contain preset key information; and under the condition that the identification result is not passed, the screening server determines that the characteristic information of the target object comprises preset key information. The screening server can send identification requests of the characteristic information of each target object one by one, and can also send identification requests of the characteristic information of all target objects in batches; accordingly, the recognition server may return the recognition results of the target objects one by one, or may return the recognition results of all the target objects in batch. The recognition result of each target object may include identification information of the target object.
In step S203, in a case that it is determined that the preset key information exists in the feature information, the screening server returns a processing request to the blockchain system, where the processing request is used to instruct the blockchain system to perform a preset processing operation on the target object.
Specifically, under the condition that the preset key information exists in the feature information, the screening server returns a processing request to the blockchain system, so that the blockchain system executes preset processing operation on a target object containing the preset key information in the feature information, and the sensitive information is shielded.
Further, considering that information on the blockchain system cannot be tampered, a concept of introducing a filtering pool on the blockchain system can be considered, a target object to be processed or shielded is stored in the filtering pool, and when a user side performs on-chain data query, the target object in the filtering pool is firstly shielded, so that the user cannot query feature information of the target object containing preset key information. Therefore, in some embodiments of the present application, the feature information may include identification information, and the processing request may carry the identification information; the preset processing operation may include: and storing the identification information of the target object into a filtering pool of the block chain system. According to the mode, the identification information of the target object containing the preset key information is stored in the filtering pool, the shielding of sensitive information can be conveniently realized, the processing cost is low, the difficulty is low, the occupied block chain resources are less, the performance of a block chain system can be prevented from being greatly reduced, the user query efficiency is improved, and the user experience is improved.
An embodiment of the present invention further provides a data processing method, as shown in fig. 3, which may include the following steps:
in step S301, the blockchain system receives an acquisition request sent by the screening server.
In step S302, the blockchain system returns the feature information of the target object to the screening server in response to the acquisition request.
Specifically, in order to determine whether the feature information of the target object contains preset key information through the screening server, the blockchain system receives an acquisition request sent by the screening server, and returns the feature information of the target object to the screening server in response to the acquisition request.
Further, in some embodiments of the present application, the characteristic information may include, but is not limited to, at least one of: identification information, name information, description information, logistics information, brand information, and production information. The identification information is a unique identification of the target object, and may be a two-dimensional code, a barcode, a character string, and the like. The production information may include information such as a production address, a production date, and a production manufacturer.
In step S303, the blockchain system receives a processing request returned by the screening server, where the processing request is used to indicate that preset key information exists in the feature information of the target object.
In step S304, the blockchain system performs a preset processing operation on the target object in response to the processing request.
Specifically, after acquiring the feature information of the target object, the screening server determines whether the feature information of the target object contains preset key information, and sends a processing request to the blockchain system if the feature information of the target object contains the preset key information. After receiving the processing request, the blockchain system performs a preset processing operation on the corresponding target object in response to the processing request to shield the target object containing preset key information in the feature information.
Further, considering that information on the blockchain system cannot be tampered, a concept of introducing a filtering pool on the blockchain system can be considered, a target object to be processed or shielded is stored in the filtering pool, and when a user side performs on-chain data query, the target object in the filtering pool is firstly shielded, so that the user cannot query feature information of the target object containing preset key information. Therefore, in some embodiments of the present application, the feature information may include identification information, and the processing request may carry the identification information; the blockchain system performs preset processing operations on the target object, which may include: the blockchain system stores the identification information of the target object into a filtering pool of the blockchain system. According to the mode, the identification information of the target object containing the preset key information is stored in the filtering pool, the shielding of sensitive information can be conveniently realized, the processing cost is low, the difficulty is low, the occupied block chain resources are less, the performance of a block chain system can be prevented from being greatly reduced, the user query efficiency is improved, and the user experience is improved.
When a user performs data query on the blockchain system, in order to shield feature information containing preset key information, the blockchain system may first determine whether an object queried by the user is in the filtering pool, and only if the object queried by the user is not in the filtering pool, the feature information of the object is returned to the user. Therefore, in some embodiments of the present application, after the blockchain system stores the identification information of the target object in the filtering pool of the blockchain system, the method may further include: a block chain system receives a data query request initiated by a user side, wherein the data query request carries identification information of a query object; in response to the received data query request, the blockchain system determines whether identification information of the query object exists in a filter pool of the blockchain system; and under the condition that the identification information of the query object is determined not to exist in the filtering pool, the blockchain system returns the characteristic information of the query object stored on the blockchain system to the user terminal.
Specifically, a user side sends a data query request to the blockchain system, wherein the data query request may include identification information of a query object; after receiving the data query request, the block chain system determines whether the identification information of the query object exists in the filter tank; and under the condition that the identification information of the query object is determined not to exist in the filtering pool, the blockchain system returns the characteristic information of the query object stored on the blockchain system to the user terminal. In the above way, the feature information of the query object is returned only in the case that the query object does not exist in the filtering tank.
Further, in some embodiments of the present application, after the blockchain system determines whether the identification information of the query object exists in the filtering pool of the blockchain system, the method may further include: in the case that the identification information of the query object exists in the filtering pool, the blockchain system returns indication information to the user terminal and hides the characteristic information of the query object, wherein the indication information is used for indicating that the query object is processed. By the method, the characteristic information of the query object containing the preset key information cannot be queried by the user. The method can be applied to an application scene that a consumer conducts tracing or anti-counterfeiting verification after purchasing commodities, and can send a data query request by scanning a two-dimensional code or a bar code and the like, wherein the two-dimensional code or the bar code is identification information of a query object.
When the data query request sent by the user side does not contain the identification information of the query object, for example, when only the name of the query object is contained, the blockchain system finds out all objects containing the name according to the received data query request, judges whether the identification information of each object in all the found objects exists in the filter tank, returns the feature information of the object to the user for the object which does not exist in the filter tank, and returns the information that the object has been processed and hides the feature information of the object to the user for the object which exists in the filter tank. By the method, data query can be performed on the block chain system, characteristic information of the object which does not contain sensitive information can be queried by the data, the characteristic information of the object which contains the sensitive information cannot be checked, and shielding processing of the sensitive information is effectively achieved.
The above method is described below with reference to a specific example, however, it should be noted that the specific example is only for better describing the present application and is not to be construed as limiting the present application.

step 4, the identification server responds to the identification request, and calls a preset key information data table to identify whether the feature information of the target object contains preset key information or not, wherein the key information data table stores a plurality of preset key information;
step 5, when the characteristic information is determined to contain at least one piece of key information in the preset key information, the identification server returns an identification result that the identification fails to pass to the screening server; under the condition that the feature information is determined not to contain any one of the preset key information, the identification server returns an identification result passing the identification to the screening server;
step 6, the screening server determines whether the characteristic information contains preset key information according to the received identification result, and determines that the characteristic information does not contain the preset key information under the condition that the identification result is that the identification is passed; determining that the characteristic information contains preset key information under the condition that the identification result is that the identification is not passed;

step 10, the blockchain system responds to the data query request, and determines whether the identification information of the query object exists in a filtering pool of the blockchain system;
step 11, in the case that the identification information of the query object is determined to exist in the filtering pool, the block chain system returns indication information to the user side and hides the characteristic information of the query object, wherein the indication information indicates that the query object has been processed;
and step 12, under the condition that the identification information of the query object is determined not to exist in the filtering pool, the blockchain system returns the characteristic information of the query object stored on the blockchain system to the user terminal.
Compared with the data processing method in the embodiment, in the step of determining on the blockchain system, the screening server synchronizes the feature information of the target object stored in the blockchain system, and the screening server calls the recognition server to determine whether preset key information exists in the feature information, so that the determination of sensitive information can be realized under a chain, the maintenance cost of the key information is reduced, the difficulty in determining whether the key information exists is reduced, and the calculation resources of the blockchain system can be saved; in addition, the screening server sends a processing request to the blockchain system under the condition that the preset key information is determined to exist, and the identification information of the target object containing the preset key information in the characteristic information is stored in the filtering pool on the blockchain system, so that the target object in the filtering pool can be firstly shielded when a user side conducts on-chain data query, and the identification information of the target object containing the preset key information is stored in the filtering pool, so that sensitive information shielding can be conveniently realized, the processing cost is low, the difficulty is low, and the occupied blockchain resources are less, the performance of the blockchain system can be prevented from being greatly reduced, the user query efficiency is improved, and the user experience is improved. The scheme solves the shielding problem of the target object containing the preset key information in a mode of combining on-chain processing and off-chain processing.
