In the prior art, the Baas platform can realize the functions of establishing a network, managing an account book, deploying an electronic contract and the like. On the Baas platform, an enterprise organization user may invoke an electronic contract to submit transaction data to the blockchain or to query transaction data from the chain.

The terminal device 101, the terminal device 102, the terminal device 103, and the terminal device 104 may be a node in a block chain 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 (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in smart home (smart home), and the like. In the embodiment of the present application, the apparatus for implementing the function of the terminal may be a terminal device, or may be an apparatus capable of supporting the terminal to implement the function, for example, a chip system, and the apparatus may be installed in the terminal device. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip 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 to this, and may also be applied to other scenarios requiring transaction detection.
It can be understood that the above-mentioned transaction detection method can be implemented by the transaction detection device provided in the embodiment of the present application, and the transaction detection device may be a part or all of a certain device, and specifically may be a node in a blockchain system, for example, the terminal device or a chip of the terminal device.
In the following, a transaction detection device integrated or installed with a relevant execution code is taken as an example, and is used as a node in a blockchain system, and a technical solution of the embodiment of the present application is described in detail with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a signaling interaction diagram of a transaction detection method according to an embodiment of the present application, which relates to a specific process of how to perform transaction detection during a transaction data uplink process. 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, an agent service module and a bottom service module. As shown in fig. 2, the method includes:
s201, the front-end application sends an uplink transaction request to the proxy service module, where the uplink transaction request includes transaction data of a pending 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 a user needs to store transaction data of a pending transaction on a blockchain system, the user can trigger sending of an uplink transaction request to a proxy service module by operating on a front-end application.
The embodiment of the application does not limit the type of the transaction data of the transaction to be processed, and the type of the transaction data can be determined according to actual conditions.
In some embodiments, the uplink transaction 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 an 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, nodes in the blockchain system also include back-end 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. For example, the front-end application may specifically send the uplink transaction request to the proxy service module by calling the back-end service module.
S202, if the transaction data of the transaction to be processed does not contain the sensitive words, the proxy service module sends an uplink transaction indication 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 the sensitive word, the proxy service module sends a transaction uplink instruction to the bottom layer service module to instruct the bottom layer 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 understood that the sensitive words may be pre-arranged specific words, such as words with a tendency to violence, non-civilized words, words with a tendency to become sensitive politically, etc.
In some embodiments, the proxy service module may sense a thesaurus of words. The sensitive word lexicon is updated in a plurality 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 library in the proxy service module according to the sensitive word change request.
Illustratively, the front-end application sends a sensitive word adding request to the proxy service module, wherein the sensitive word adding request comprises a sensitive word. Subsequently, the proxy service module adds the sensitive words in a sensitive word bank in the proxy service module.
For example, the proxy service module may also periodically and actively acquire common sensitive words from the network, so as to periodically update the sensitive word bank.
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 satisfies a rule of the electronic contract, and only when the transaction data of the transaction to be processed does not include the sensitive word and satisfies the rule of the electronic contract, the proxy service module sends the uplink transaction indication to the underlying service module.
In some optional embodiments, if the transaction data of the to-be-processed transaction includes the 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 to-be-processed transaction. For example, if the transaction data of the pending transaction contains the sensitive word, the proxy service module may send a second message with "the transaction contains the sensitive word" from the front-end application.
S203, the bottom layer service module writes the transaction data of the transaction to be processed into the blockchain system.
In the embodiment of the present application, there is no limitation on the bottom service module writing the transaction data of the transaction to be processed into the blockchain system, and a common manner may be adopted.
In some optional embodiments, after the underlying service module writes the transaction data of the pending transaction into the blockchain system, the proxy service module sends a first message to the front-end application, where the first message is used to indicate that the transaction data of the pending transaction is successfully written into the blockchain system.
The transaction detection method provided by the embodiment of the application is applied to nodes in a blockchain system, wherein the nodes in the blockchain system comprise a front-end application, an agent service module and a bottom service module, 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 the sensitive words, the proxy service module sends a transaction uplink instruction to the bottom service module; the bottom layer service module writes the transaction data of the transaction to be processed into the block chain system. Compared with the prior art, the method and the device have the advantages that before the transaction data are linked, the transaction data are detected according to the sensitive words, and the transaction data with the sensitive words which do not accord with 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 accord with the specification is realized.
On the basis of the above embodiment, a process of detecting that the transaction data includes the sensitive word is described below. Fig. 3 is a signaling interaction diagram of another transaction detection method provided in an embodiment of the present application, as shown in fig. 3, the method includes:
s301, the front-end application sends an uplink transaction request to the proxy service module, wherein the uplink transaction request comprises transaction data of the transaction to be processed.
S302, the agent service module judges whether the transaction data of the transaction to be processed contains sensitive words.
If so, step S305 is executed, and if not, step S303 is executed.
S303, the proxy service module sends the trade uplink indication to the bottom service module.
S304, the bottom layer service module writes the transaction data of the transaction to be processed into the block chain system.
The technical terms, technical effects, technical features and alternative embodiments of S301 to S304 can be understood by referring to S201 to S203 shown in fig. 2, and repeated descriptions thereof will not be repeated here.
S305, the proxy service module sends a second message to the front-end application, wherein the second message is used for indicating the sensitive words in the 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 the 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 receiving the second message may display the second message on a display component of a node in the blockchain system. For example, the sensitive words may be displayed on a display screen of a node in the blockchain system, and the positions of the sensitive words are marked, so as to remind the user to modify the transaction data to meet the quality requirement 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 words, the proxy service module sends a second message to the front-end application to send an error prompt to the user, so that the user can find the sensitive words in the transaction data of the transaction to be processed in time and modify the sensitive words in time, and the content quality of the transaction data recorded on the blockchain system is improved.
On the basis of the above embodiment, since the sensitive words may change over time, the transaction data that has been linked up may also have the sensitive words in the subsequent query process. Therefore, the transaction detection method provided in the embodiment of the present application performs sensitive word detection in the process of transaction data link, as well as in the process of transaction data query. The following describes how to perform the sensitive word detection process in the transaction data query process. Fig. 4 is a signaling interaction diagram of another transaction detection method provided in an embodiment of the present application, as shown in fig. 4, the method includes:
s401, the front-end application sends a query request to the proxy service module, wherein the query request comprises the identification of the transaction to be queried.
In this step, the user may input an inquiry instruction to the proxy service module through the front-end application in addition to the uplink transaction request to the proxy service module through the front-end application, so as to inquire the transaction data stored in the blockchain system.
The transaction to be queried is not limited in the embodiment of the present application, and the transaction data of the blockchain system may be written into the node in the blockchain system, or the transaction data of the blockchain system may be written into the nodes in other blockchain systems.
S402, the agent service module sends a query instruction to the bottom layer service module according to the query request.
In some embodiments, the query indication 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 right. If the agent service module inquires that the user has the right to inquire the transaction data, the agent service module can send an inquiry instruction to the bottom layer service module according to the inquiry request.
Wherein the query indication may also contain an identification of the transaction to be queried.
And S403, the bottom layer service module acquires the transaction data of the transaction to be inquired according to the inquiry instruction.
In some embodiments, the underlying service module may obtain transaction data of 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 inquired to the agent service module.
S405, the agent service module judges whether the transaction data of the transaction to be inquired contains sensitive words.
If so, step S407 is executed, and if not, 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 embodiment, which is not described herein again.
S406, the agent service module sends the transaction data of the transaction to be inquired to the front-end application.
S407, the agent service module executes sensitive transaction processing operation.
Wherein the sensitive transaction processing operations include: recording the transaction to be inquired as a sensitive transaction, sending a sensitive transaction prompt to the front-end application, and accumulating the times of the behavior of calling the sensitive transaction by the user 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 execute one sensitive transaction processing operation or multiple sensitive transaction processing operations, which is not limited in the present application.
S408, if the number of times of the user using the front-end application to invoke the sensitive transaction exceeds a threshold value, the proxy service module sends a forbidden indication to the front-end application, wherein the forbidden indication contains account information of the user.
Wherein the disabling indication sent by the sensitive transaction server may further contain an identification of the disabled user.
S409, the front-end application stops receiving the uplink transaction request and/or inquiry request input by the user.
The embodiments of the present application are not limited to how to stop receiving user-entered uplink transaction requests and/or inquiry requests, and may, for example,
for example, the front-end application may invoke the proxy service module to suspend the user, and then the proxy service module may update the user's status to a suspended status, and the node in the blockchain system stops receiving the ul requests and/or query indications input by the user.
In other embodiments, after receiving the indication from the management node, the proxy service module may also reactivate the user so that the node in the blockchain system re-executes the ul request and/or the query indication entered by the user.
In the transaction detection method provided by the embodiment of the application, the front-end application sends a query request to the proxy service module, and the query request includes the identification of the transaction to be queried.
