In order to ensure information intercommunication in the blockchain network, information connection can exist between each node in the blockchain network, and information transmission can be carried out between the nodes through the information connection. For example, when any node in the blockchain network receives input information, other nodes in the blockchain network acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain network are consistent.
The terminal device 102 may access the blockchain network and may communicate with nodes in the blockchain network, e.g., may submit transaction data to the nodes, etc. The terminal device 102 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, and the like, which is not limited in this embodiment. It should be noted that the number of nodes shown in fig. 1A is merely illustrative, and any number of nodes may be deployed according to actual needs.
Each node in the blockchain network has a corresponding node identifier, and each node in the blockchain network can store node identifiers of other nodes in the blockchain network, so that the generated block can be broadcast to other nodes in the blockchain network according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.
| Node name | Node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| … | … |

The ticket herein may be an electronic ticket or a digital ticket including, but not limited to, an order or an invoice.
In one embodiment, the user may submit the target transaction data directly to a node in the blockchain network through the terminal device, or may submit the target transaction data indirectly to a node in the blockchain network through the terminal device. That is, the target transaction data submitted by the user through the terminal device may be sent to the node by the terminal device, or the target transaction data submitted by the user through the terminal device may also be sent to the node by other devices, such as a service device.
In one embodiment, considering that some transaction data with higher reliability can be directly uplink, some transaction data with lower reliability generally needs sensitive information judgment, and some transaction data with lower reliability can be directly uplink rejected, so the node can determine the category to which the target transaction data belongs; if the target transaction data is determined to belong to the first category, the node may write the target transaction data into the block chain; if it is determined that the target transaction data belongs to the second category, the node may perform step S202; if the target transaction number is determined to belong to the third category, the node may refuse to write the target transaction data into the blockchain.
In one embodiment, the node may determine the category to which the target transaction data belongs according to target user information (e.g., user information for the user or user information for other users) included in the target transaction data. Specifically, the node may obtain the category to which the user indicated by the target user information belongs, and determine the category to which the target transaction data belongs according to the category to which the user indicated by the target user information belongs. Several ways of determining the category to which the target transaction data belongs based on the target user information included in the target transaction data will be briefly described below.
In one embodiment, the target user information includes user identification information, such as the user account number or name, the node may query the credit evaluation level of the user corresponding to the user identification information, and if the credit evaluation level is a first level (e.g., high), the node may determine that the target transaction data belongs to a first category; if the credit evaluation level is a second level (e.g., medium), the node may determine that the target transaction data belongs to a second category; if the credit evaluation level is determined to be a third level (e.g., low), the node may determine that the targeted transaction data belongs to a third category. Or, the node may query a credit score of the user corresponding to the user identification information, and if the credit score is in a first value range (e.g., c-d, d > c), the node may determine that the target transaction data belongs to a first category; if the credit score is in a second value range (e.g., b — (c-1), b < (c-1)), the node may determine that the target transaction data belongs to a second category; if the credit score is in a third range (e.g., a — (b-1), a < (b-1))), the node may determine that the target transaction data belongs to a third category.
In one embodiment, the target user information of the user includes identification information of the user, such as an account number or a name of the user, the node may query the importance level of the user according to the identification information of the user, and if the importance level of the user is a first level (e.g., important), the node may determine that the target transaction data belongs to a first category; if the importance level of the user is a second level (e.g., general), the node may determine that the target transaction data belongs to a second category; if the importance level of the user is determined to be a third level (e.g., lower), the node may determine that the targeted transaction data belongs to a third category.
In one embodiment, the node may determine a category to which the target transaction data belongs based on the set of information. Specifically, if it is determined that the target transaction data includes information in the first information set, the node may determine that the target transaction data belongs to a first category; if the target transaction data is determined to comprise information in the second information set, the node determines that the target transaction data belongs to the second category; if the target transaction data is determined to include information in the third information set, the node determines that the target transaction data belongs to a third category.
In one embodiment, the node may determine a probability that the target transaction data includes sensitive information, and if the probability is greater than or equal to a preset value, perform step S202. In one embodiment, if the probability is less than a preset value, the target transaction data is written to the blockchain.
In one embodiment, the process of the node determining the probability that the target transaction data includes the sensitive information may be to obtain, for the node, a historical transaction record of the user, where the historical transaction record includes a plurality of transaction data submitted by the user through the terminal device, count, by the node, a proportion of the transaction data including the sensitive information in the plurality of transaction data, and estimate the probability that the target transaction data includes the sensitive information according to the proportion of the transaction data including the sensitive information.
S202, filtering text information in the target transaction data by using a sensitive word filtering library to determine whether the target transaction data comprises sensitive information, wherein the sensitive word filtering library comprises a plurality of sensitive keywords.

In the embodiment of the application, the node can match the sensitive word filter library with the text information in the target transaction data, so that whether the target transaction data comprises sensitive information or not is determined according to the matching result, and when the target transaction data comprises the sensitive information, the target transaction data is refused to be written into the block chain, and meanwhile, a notification message is sent to the terminal device.
In one embodiment, the node determining whether the target transaction data includes sensitive information according to the matching result may be that if the matching result indicates that the text information in the target transaction data includes at least one sensitive keyword in the sensitive word filter library, the node may determine that the target transaction data includes sensitive information; alternatively, if the matching result indicates that the text information in the target transaction data has a keyword (i.e., a keyword with a similarity greater than a preset similarity) similar to the target sensitive keyword (any keyword of the plurality of sensitive keywords included in the sensitive word filter library) in the sensitive word filter library, the node may determine that the target transaction data includes the sensitive information.
In one embodiment, a node may include the sensitive word filter library, that is, a node may filter text information in the target transaction data by using the sensitive word filter library included in the node to determine whether the target transaction data includes sensitive information. Or, the database may include the sensitive word filter library, that is, the node may filter the text information in the target transaction data by using the sensitive word filter library through the database to determine whether the target transaction data includes sensitive information.
In one embodiment, where a node includes the sensitive word filter library, the included sensitive word filter library of the node may be obtained by the node from the database, or may also be broadcast to the node by a designated device, for example, when transaction data corresponding to each of at least one of the tickets is stored in the blockchain, the included sensitive word filter library of the node may be broadcast to the node by a tax bureau server.
In one embodiment, the node may update the sensitive word filter library by: and the node acquires the updating data of the sensitive word filtering library and updates the sensitive word filtering library by using the updating data. In one embodiment, the node may obtain update data of the sensitive word filter library from a database and update the sensitive word filter library with the update data, or the node may further receive update data of the sensitive word filter library broadcast by a specific device and update the sensitive word filter library with the update data, for example, when transaction data corresponding to each of at least one ticket is stored in a block chain, the node may receive update data of the sensitive word filter library broadcast by a tax authority server and update the sensitive word filter library with the update data.
In one embodiment, the update data may filter a library for new sensitive words. The process of updating the sensitive word filter library by the node by using the updating data can replace the sensitive word filter library by using a new sensitive word filter library for the node. In one embodiment, considering that the new sensitive word filter library is only added with some sensitive keywords compared with the sensitive word filter library, when the update data includes a first sensitive keyword, the first sensitive keyword refers to a sensitive keyword that appears in the new sensitive word filter library but does not appear in the sensitive word filter library, the node may compare the new sensitive word filter library with the sensitive word filter library to determine a first sensitive keyword of the new sensitive word filter library, and the node may add the first sensitive keyword to the sensitive word filter library. In one embodiment, considering that the new sensitive word filtering library has some sensitive keywords deleted or modified, when the update data includes a second sensitive keyword, the second sensitive keyword refers to a sensitive keyword that does not appear in the new sensitive word filtering library but appears in the sensitive word filtering library, and the node may delete the second sensitive keyword of the sensitive word filtering library.
In one embodiment, the node may also discard the target transaction data after denying writing the target data to the blockchain.
It can be seen that, in the embodiment shown in fig. 2, a node in the blockchain network may obtain target transaction data submitted by a user through a terminal device, and filter text information in the target transaction data by using a sensitive word filter library to determine whether the target transaction data includes sensitive information, so that the target transaction data includes the sensitive information, the target transaction data is rejected from being written into the blockchain, and a notification message is sent to the terminal device, where the notification message is used to prompt that the target transaction data includes the sensitive information.

In one embodiment, the node may perform the step of obtaining the transaction data corresponding to each of the at least one item stored in the blockchain when the specified scan period reaches or detects that there is an update in the sensitive word filter library.
In one embodiment, the process of the node acquiring the transaction data corresponding to each of the at least one ticket stored in the blockchain may be: the node acquires the bill query condition and determines a target block which is matched with the bill query condition in the blocks included in the block chain, so that the transaction data corresponding to each bill in at least one bill stored in the target block is queried. Wherein, the bill inquiry condition comprises a time period or a block height range. When the ticket query condition includes a time period, since each tile may correspond to a tile generation time, the node may determine, from the tiles included in the tile chain, a tile generated within the time period as a target tile matching the query condition. When the ticket query includes a block height range, since each block may correspond to a block height, the node may determine, from the blocks included in the block chain, a block within the block height range as a target block matching the query.
In one embodiment, the node may perform the step of obtaining the ticket query condition when a specified scan period arrives or detects that there is an update to the sensitive word filter library.

In one embodiment, if the matching result indicates that the text information corresponding to the ticket includes at least one sensitive keyword in the sensitive word filter library, the node may determine that the transaction data corresponding to the ticket includes sensitive information; alternatively, if the matching result indicates that the text information corresponding to the ticket has a keyword similar to the second sensitive keyword in the sensitive word filter library, the node may determine that the transaction data corresponding to the ticket includes the sensitive information. The second sensitive keyword may be the same as or different from the first sensitive keyword.

In one embodiment, the node sends the marking information to a tax office server, so that the tax office server sets the target ticket to prohibit querying or hide sensitive information in the target ticket according to the marking information. By adopting the process, the target bill can be effectively prevented from spreading information to the outside. In one embodiment, after the tax office server sets the target bill as a forbidden query according to the identification information, if a query request of other terminal equipment for the target bill is received, the tax office server may not respond to the query request, or return a prompt message of a query error to other terminal equipment, or return a prompt message without the target bill to other terminal equipment.
