All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Blockchains refer to traceable, non-tamperable, distributed billing mechanisms implemented by cryptographic techniques, point-to-point networks, consensus mechanisms, and block-chained data structures organized in time series. Wherein the blockchain backend as-a-service (blockchain AS A SERVICE, baaS) platform can quickly create, deploy, run, and monitor blockchain applications.
In the prior art, the Baas platform can realize the functions of constructing a network, managing an account book, deploying an electronic contract and the like. On the Baas platform, enterprise organization users may invoke electronic contracts to submit transaction data to the blockchain or to query transaction data from the chain. However, when receiving transaction data submitted to the chain by the enterprise organization by calling the electronic contract, the conventional Baas platform only needs to detect whether the transaction data meets the rule of the electronic contract, and does not need to detect specific content of the transaction data, so that the problem that the blockchain system such as Baas platform cannot filter the transaction data of which the content does not meet the specification is caused.

When the user writes transaction data into the blockchain system through the terminal device 101, the terminal device 101 can detect the sensitive word of the transaction data input by the user, and only the transaction data without the sensitive word is written into the blockchain system by the terminal device 101.
The terminal device 101, the terminal device 102, the terminal device 103, and the terminal device 104 may be one node in a blockchain system. The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (SMART GRID), a wireless terminal in smart home (smart home), or the like. In the embodiment of the present application, the device for implementing the function of the terminal may be a terminal device, or may be a device capable of supporting the terminal to implement the function, for example, a chip system, and the device may be installed in the terminal device. In the embodiment of the application, the chip system can be composed of chips, and can also comprise chips and other discrete devices.
It should be noted that, the application scenario of the technical solution of the present application may be the scenario in fig. 1, but is not limited thereto, and may be applied to other scenarios where transaction detection is required.
It may be understood that the transaction detection method may be implemented by the transaction detection device provided by the embodiment of the present application, where the transaction detection device may be part or all of a device, and specifically may be a node in a blockchain system, for example, the terminal device or a chip of the terminal device.
The following takes a transaction detection device integrated with or installed with related execution codes as an example, and uses specific embodiments to describe the technical solution of the embodiment of the present application in detail as a node in a blockchain system. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a signaling interaction diagram of a transaction detection method according to an embodiment of the present application, where the embodiment relates to a specific process of how to perform transaction detection in a process of uplink transaction data. The execution subject of the application is a transaction detection device which can be a node in a blockchain system, wherein the node in the blockchain system comprises a front-end application, a proxy service module and a bottom layer service module. As shown in fig. 2, the method includes:
s201, the front-end application sends a transaction uplink request to the proxy service module, wherein the transaction uplink request comprises transaction data of a to-be-processed transaction.
The front-end application may be an application that supports uploading transaction data to the blockchain system. The proxy service module may be a service module that manages requests initiated by the front-end application.
In the application, when the user needs to store the transaction data of the transaction to be processed on the blockchain system, the operation can be performed on the front-end application, so that the transaction uplink request is triggered to be sent to the proxy service module.
The embodiment of the application does not limit the type of the transaction data of the transaction to be processed, and can determine the type of the transaction data according to the actual situation.
In some embodiments, the transaction uplink request input by the user may further include identification or account information of the user, and the proxy service module may verify whether the user has authority to write the transaction data into the blockchain system by verifying the identification or account information of the user.
It should be appreciated that in some embodiments, the nodes in the blockchain system further include backend service modules corresponding to the front-end applications. The back-end service module is used for processing the operation triggered by the user on the page of the front-end application. The front-end application may specifically send a transaction uplink request to the proxy service module by invoking the back-end service module, for example.
S202, if the transaction data of the transaction to be processed does not contain sensitive words, the proxy service module sends a transaction uplink instruction to the bottom layer service module.
In this step, after the proxy service module receives the transaction uplink request sent by the front end application, the proxy service module may perform sensitive word detection on the transaction data of the transaction to be processed, and if the transaction data of the transaction to be processed does not include a sensitive word, the proxy service module sends a transaction uplink instruction to the bottom service module to instruct the bottom service module to write the transaction data into the blockchain system.
The bottom layer service module is used for writing and inquiring transaction data on the blockchain system.
It should be appreciated that the sensitive words may be pre-set specific words, such as words with a violent tendency, non-civilized words, words with a sensitive political tendency, etc.
In some embodiments, the proxy service module may be sensitive to word thesaurus. The sensitive word stock is updated in a number of ways.
For example, the proxy service module may receive a sensitive word change request sent by the management node, and then the proxy service module adds or deletes a sensitive word in a sensitive word stock in the proxy service module according to the sensitive word change request.
Illustratively, the front-end application sends a sensitive word addition request to the proxy service module, the sensitive word addition request including the sensitive word. Then, the proxy service module adds sensitive words in a sensitive word stock in the proxy service module.
The proxy service module can also periodically and actively acquire common sensitive words from the network, so that the sensitive word stock is periodically updated.
In some embodiments, before writing the transaction data of the transaction to be processed into the blockchain system, the proxy service module may further detect whether the transaction data meets a rule of the electronic contract, and only when the transaction data of the transaction to be processed does not include a sensitive word and meets the rule of the electronic contract, the proxy service module sends a transaction uplink indication to the bottom layer service module.
In some alternative embodiments, if the transaction data of the transaction to be processed includes a sensitive word, the proxy service module sends a second message to the front-end application, where the second message is used to indicate the sensitive word in the transaction data of the transaction to be processed. For example, if the transaction data of the transaction to be processed includes a sensitive word, the proxy service module may send a second message with "transaction includes a sensitive word" by the front-end application.
S203, the bottom layer service module writes transaction data of the transaction to be processed into the blockchain system.
In the embodiment of the application, the transaction data of the transaction to be processed is written into the blockchain system by the bottom layer service module without limitation, and a common mode can be adopted.
In some alternative embodiments, after the underlying service module writes the transaction data for the pending transaction to the blockchain system, the proxy service module sends a first message to the front-end application, the first message indicating that the transaction data for the pending transaction was successfully written to the blockchain system.
The transaction detection method provided by the embodiment of the application is applied to the nodes in the block chain system, wherein the nodes in the block chain system comprise front-end application, proxy service modules and bottom layer service modules, and the method comprises the following steps: the front-end application sends a transaction uplink request to the proxy service module, wherein the transaction uplink request comprises transaction data of a transaction to be processed; if the transaction data of the transaction to be processed does not contain sensitive words, the proxy service module sends a transaction uplink instruction to the bottom layer service module; the bottom layer service module writes transaction data of the pending transaction into the blockchain system. Compared with the prior art, the method and the system have the advantages that before the transaction data are uplink, the transaction data are detected according to the sensitive words, and the transaction data with the sensitive words which do not meet the specification are not written into the blockchain system, so that the function that the blockchain system can filter the transaction data with the content which does not meet the specification is realized.
On the basis of the above embodiment, the following describes a process for detecting that the transaction data contains a sensitive word. Fig. 3 is a signaling interaction diagram of another transaction detection method according to an embodiment of the present application, as shown in fig. 3, where the method includes:
S301, the front-end application sends a transaction uplink request to the proxy service module, wherein the transaction uplink request comprises transaction data of a to-be-processed transaction.
S302, the proxy service module judges whether the transaction data of the transaction to be processed contains sensitive words.
If yes, step S305 is executed, and if no, step S303 is executed.
S303, the proxy service module sends a transaction uplink instruction to the bottom layer service module.
S304, the bottom layer service module writes transaction data of the transaction to be processed into the blockchain system.
The technical terms, effects, features, and alternative embodiments of S301-S304 may be understood with reference to S201-S203 shown in fig. 2, and will not be described again here for repeated matters.
S305, the proxy service module sends a second message to the front-end application, wherein the second message is used for indicating sensitive words in transaction data of the transaction to be processed.
In this step, if it is detected that the transaction data of the transaction to be processed includes a sensitive word, the proxy service module sends a second message to the front-end application, where the second message is used to indicate the sensitive word in the transaction data of the transaction to be processed.
It should be appreciated that the front-end application receives the second message, which may be displayed on a display component of a node in the blockchain system. The sensitive words can be displayed on a display screen of a node in the blockchain system, and the positions of the sensitive words are marked, so that a user is reminded to modify transaction data to meet the quality requirements of the content.
In the transaction detection method provided by the application, when the transaction data of the transaction to be processed contains the sensitive word, the proxy service module sends the second message to the front-end application to send the error prompt to the user, so that the user can find the sensitive word in the transaction data of the transaction to be processed in time and modify the sensitive word in time, and further the content quality of the transaction data recorded on the blockchain system is improved.
On the basis of the embodiment, since the sensitive words may change with time, the already-chained transaction data may also have the sensitive words in the subsequent query process. Therefore, the transaction detection method provided by the embodiment of the application not only carries out sensitive word detection in the process of uploading transaction data, but also carries out sensitive word detection in the process of inquiring transaction data. The following describes how sensitive word detection is performed during a transaction data query. Fig. 4 is a signaling interaction diagram of another transaction detection method according to an embodiment of the present application, as shown in fig. 4, where the method includes:
s401, the front-end application sends a query request to the proxy service module, wherein the query request comprises an identification of a transaction to be queried.
In this step, the user may input a query instruction to the proxy service module through the front-end application in addition to the transaction uplink request to the proxy service module through the front-end application, so as to query transaction data stored in the blockchain system.
The embodiment of the application does not limit the transaction to be queried, can write the transaction data of the blockchain system for the nodes in the blockchain system, and can also write the transaction data of the blockchain system for the nodes in other blockchain systems.
S402, the proxy service module sends a query instruction to the bottom layer service module according to the query request.
In some embodiments, the query instruction may further include an identifier of the user or account information of the user, so that the proxy service module verifies whether the user has the query authority. If the proxy service module inquires that the user has the authority to inquire the transaction data, an inquiry instruction can be sent to the bottom layer service module according to the inquiry request.
The query indication may also include an identification of the transaction to be queried.
S403, the bottom layer service module acquires transaction data of the transaction to be queried according to the query instruction.
In some embodiments, the underlying service module may obtain transaction data for the transaction to be queried from the transaction data stored in the blockchain system according to the identification of the transaction to be queried.
S404, the bottom layer service module sends the transaction data of the transaction to be queried to the proxy service module.
S405, the proxy service module judges whether the transaction data of the transaction to be queried contains sensitive words.
If yes, step S407 is executed, and if no, step S406 is executed.
It should be noted that, in the embodiment of the present application, the manner of determining whether the transaction data of the transaction to be queried includes the sensitive word may refer to the manner of determining whether the transaction data of the transaction to be processed includes the sensitive word in the above embodiment, which is not described herein in detail.
S406, the proxy service module sends the transaction data of the transaction to be queried to the front-end application.
S407, the proxy service module executes sensitive transaction processing operation.
Wherein the sensitive transaction processing operations include: recording the transaction to be queried as a sensitive transaction, sending a sensitive transaction prompt to the front-end application, and accumulating the times of the actions of calling the sensitive transaction by the user by using the front-end application.
It should be noted that, if the transaction data of the transaction to be queried includes a sensitive word, the proxy service module may perform one sensitive transaction processing operation, or may perform multiple sensitive transaction processing operations, which is not limited in the present application.
S408, if the number of times of calling the sensitive transaction by the user through the front-end application exceeds a threshold, the proxy service module sends a forbidden indication to the front-end application, wherein the forbidden indication comprises account information of the user.
Wherein the disabling indication sent by the sensitive transaction server may also contain an identification of the disabled user.
S409, the front-end application stops receiving the transaction uplink request and/or the query request input by the user.
Embodiments of the present application are not limited in terms of how to cease receiving user-entered transaction uplink requests and/or query requests, and, by way of example,
Illustratively, the front-end application may invoke the proxy service module to suspend the user, and the proxy service module may then update the user's status to the suspended status, with nodes in the blockchain system ceasing to receive the user-entered transaction uplink request and/or query indication.
