Specifically, referring to fig. 1, fig. 1 is a message filtering architecture diagram provided in an embodiment of the present application, as shown in fig. 1, the present solution is described based on a message filtering system as a main body, where the message filtering system 11 includes a message block chain, a message processing node 111, a message classification node 112, and a configuration node 113, when a client 10 sends a message sending request to the message filtering system 11, where the message sending request includes a message identifier, a group identifier, and a message content, the message sending request is used to indicate that the client 10 sends a message in a group corresponding to the group identifier, the sent message is the message content, and the message identifier is used to mark the message content. After receiving a message sending request sent by the client 10, the message filtering system 11 performs consensus on the message content through the message processing node 111, and then obtains a message filtering configuration information set corresponding to the group identifier from the message block chain through the configuration node 113, where the message filtering configuration information set includes message filtering configuration information associated with multiple users and multiple message content categories, and then inputs the message content into the message classification model through the message classification node 112 to perform learning to obtain a message content category corresponding to the message content, and the message filtering system 11 obtains the message filtering configuration information corresponding to the message content category from the obtained message filtering configuration information set, where one message content may correspond to multiple message content categories. Acquiring message filtering configuration information corresponding to the message filtering configuration information set from the message filtering configuration information set, wherein each message filtering configuration information is determined based on a group identifier and a message content category and comprises receiving state settings of a plurality of users for the message content category in the group corresponding to the group identifier, so that a receiving user of the message content is determined according to the message filtering configuration information corresponding to the message content category, and the message content is sent to a receiving terminal 12 of the determined receiving user. The message processing node 111 is configured to receive a message sent by a client, perform consensus confirmation on the message, determine message filtering configuration information corresponding to the message, and the like, the message classification node 112 is configured to obtain a message content category corresponding to the message sent by the client through a message classification model, and the configuration node 113 is configured to obtain a message filtering configuration information set according to the obtained message filtering configuration information set for a group sent by the client. The message processing node 111, the message classification node 112, and the configuration node 113 may be different modules in the message filtering system 11, or may be servers or terminal devices in the message filtering system 11, and implement filtering of group messages by executing the above processes. For example, when a user a sends a group message to a group 1 through a client 10, after monitoring the group message, the message filtering system 11 performs consensus on the group message through the message processing node 111, determines that the group message is accurate, acquires a message filtering configuration information set corresponding to a group identifier from a message block chain according to the group identifier corresponding to the group message, inputs the group message into a message classification model through the message classification node 112, and acquires message content categories corresponding to the group message, where the message content categories include "landscape" and "advertisement", and acquires message filtering configuration information corresponding to message content categories "landscape" and "advertisement", and the acquired message filtering configuration information corresponding to the "landscape" includes "user B: refusing; and a user C: receiving message filtering configuration information corresponding to the advertisement, wherein the message filtering configuration information comprises user C: refusing; and a user D: refusing to receive the group message, so as to determine that the receiving user of the group message is a group member except the user B, the user C and the user D in the group 1, and sending the group message to the terminal equipment logged in by the group member except the user B, the user C and the user D in the group 1.

Further, please refer to fig. 2, fig. 2 is a flowchart of a message filtering method according to an embodiment of the present application. As shown in fig. 2, the message filtering process includes the following steps:

step S201, receiving a message sending request sent by a client, where the message sending request includes a message identifier, a group identifier, and a message content.

Specifically, when a user sends message content to a group through a client, the client monitors the message content sending process and sends a message sending request to a message filtering system, the message filtering system receives the message sending request sent by the client, the message sending request comprises a message identifier, a group identifier and message content, the message identifier is used for indicating the message content, and the group identifier is used for indicating the group for sending the message content by the client. Wherein, since different users may send the same message content, a message content can be uniquely specified by the message identifier. Optionally, after receiving a message sending request sent by the client, the message filtering system may generate a message sending block according to the message sending request, perform consensus on the message sending block through a message processing node in the system to determine the authenticity of the message sending request, if it is determined that the message sending request is authentic, upload the message sending block to a message block chain, and execute step S202, if it is determined that the message sending request is not authentic, end the message sending process this time, and send a prompt of message sending failure to the client; the message sending block comprises a message identifier, a group identifier, message content, a user identifier and the like, wherein the user identifier is used for indicating a login user when the client sends the message content in a group corresponding to the group identifier.

For example, when a user a logs in a client, a message content is sent to a group 1 through the client, the message content is a picture, when the client monitors a message sending process that the user a sends the message content to the group 1, a message sending request is sent to a message filtering system, the message sending request includes a message identifier, a group identifier and the message content, and the message sending request also carries a user identifier of the user a and is used for indicating a sending user of the message content in the message sending request. After receiving the message sending request, the message filtering system generates a message sending block according to the message sending request, where the message sending block includes "the user identifier of the user a, the message identifier, the group identifier 1 corresponding to the group 1, and the message content", and performs consensus on the message sending block through the message processing node, if the consensus passes, it is determined that the message sending request is accurate, the message sending block is uploaded to a message block chain to record an event that the user a sends the message content to the group 1, and step S202 is executed.

Step S202, obtaining the message filtering configuration information set corresponding to the group identification from the message block chain.

Specifically, a message filtering configuration information set corresponding to the group identifier is obtained from the message block chain, and the message filtering configuration information set includes message filtering configuration information associated with a plurality of users and a plurality of message content categories. Specifically, a plurality of message filtering configuration information sets are stored in the message blockchain, each message filtering configuration information set corresponds to a group identifier and is used for recording relevant message filtering configuration information of a group corresponding to the group identifier, each group identifier is associated with a plurality of message content categories, and each message content category is associated with at least one user. Optionally, the message filtering configuration information set may also be stored at the configuration node, and a message block chain stores message configuration blocks, each message configuration block is used to store data generated when an event that a user configures the message filtering information occurs, and when a message sending request sent by a client is received, the message filtering configuration information set corresponding to the group identifier is obtained from the configuration node, where the configuration node stores therein a message filtering configuration information set corresponding to at least one group identifier, and at least one message filtering configuration information set is generated and updated according to the message configuration blocks in the message block chain, that is, when a message configuration block is uploaded to the message block chain, the data in the message configuration block is added to at least one message filtering configuration information set by the configuration node.

Specifically, if the message filtering configuration information set is only stored in the message block chain, at least one block associated with the group identifier is acquired from the message block chain through the group identifier, the message filtering information set corresponding to the group identifier is determined according to the at least one block, the message filtering configuration information is identified in common, and if the common identification passes, step S203 is executed, wherein each block in the at least one block stores data generated when an event for configuring the message filtering information by the user occurs; if the message filtering configuration information set is stored in the message block chain and the configuration node, the message filtering information set corresponding to the group identifier may be directly obtained from the configuration node, and the message filtering configuration information is identified, and if the identification passes, step S203 is executed.

Referring specifically to fig. 3, fig. 3 is a schematic diagram of a message filtering configuration information set provided in an embodiment of the present application, and as shown in fig. 3, a group identifier corresponds to a message filtering configuration information set, the message filtering configuration information set includes at least one message content category associated with the group identifier, each message content category is associated with at least one configuration user, where each message content category includes a number ID, a content category description, and a configuration user, the number ID is used to identify the message content category, the content category description is a description of the corresponding message content category, and the configuration user includes at least one configuration user associated with the corresponding message content category and a message acquisition status configured by each configuration user with respect to the corresponding message content category. Taking fig. 3 as an example, the message filtering configuration information set corresponding to the group identifier 1 is obtained from the message block chain through the group identifier 1, the message filtering configuration set includes message filtering configuration information associated with n message content categories and a plurality of users, i.e. the group identity 1 is associated with n message content categories, including message content category 1, message content category 2, … and message content category n, each message content category corresponding to a message filtering configuration information, each message filtering configuration information containing at least one configuration user associated with the corresponding message content category, if the message filtering configuration information corresponding to the message content category 1 includes the user a, the user B and the user C associated with the message content category 1, and the message acquisition state configured by each user comprises a receiving state and a rejecting state.

Step S203, identifying the message content category corresponding to the message content through the message classification model, and obtaining the message filtering configuration information corresponding to the message content category from the message filtering configuration information set.

Specifically, the message content is input into the message classification model for learning to obtain a message content category corresponding to the message content, and the message filtering configuration information corresponding to the message content category is obtained from the message filtering configuration information set corresponding to the group identifier according to the message content category. The message classification model may be an image classification model, a text classification model, or the like, and the message classification model includes, but is not limited to, a Convolutional Neural Network (CNN), or the like. The message filtering system inputs the message content into a message classification model for learning, classifies the message content to obtain a message content category corresponding to the message content, wherein the message content may correspond to one or more message content categories, and obtains message filtering configuration information associated with the message content category corresponding to the message content from a message filtering configuration information set corresponding to the obtained group identifier. Optionally, after the message content category corresponding to the message content is obtained, the serial numbers ID of the message content category corresponding to the message content may be integrated to generate a message classification block, and after the message classification block is identified, the message classification block is uploaded to a message block chain.

For example, as shown in fig. 3, after inputting the message content into the message classification model for learning, the message content category corresponding to the message content is obtained to include the message content category 1 and the message content category 2, and the data associated with the message content category 1 and the message content category 2 is obtained from the message filtering configuration information set corresponding to the obtained group identifier 1, so as to obtain the message filtering configuration information corresponding to the message content category 1 and the message filtering configuration information corresponding to the message content category 2. Specifically, based on the example shown in step S202, assuming that the message content category 1 is landscape, the message content category 2 is advertisement, …, and the message content category n is animal, after inputting the message content into the message classification model and learning, the message content category corresponding to the message content is "landscape and advertisement", and the message filtering configuration information corresponding to the message content category is obtained from the message filtering configuration information set, and includes the message filtering configuration information "number ID1 corresponding to the message content category" landscape ", and the content category description-information such as landscape-only images, text, or links, and the user is configured: refusing by user A, refusing by user B and receiving by user C, message filtering configuration information ' number ID2 corresponding to message content type ' advertisement ', message of content type description-advertisement type image, text or link, etc., configuring user: user C refuses, user D refuses ".

Step S204, according to the message filtering information corresponding to the message content category, determining the receiving user of the message content, and sending the message content to the receiving terminal of the receiving user.

Specifically, the group members included in the group corresponding to the group identifier are acquired according to the group identifier, the receiving user of the message content is determined according to the message filtering configuration information and the group members corresponding to the obtained message content category, and the message content is sent to the receiving terminal of the determined receiving user. Referring to fig. 4 in particular, fig. 4 is a schematic diagram of a certain receiving user according to an embodiment of the present application. As shown in fig. 4, according to the obtained message filtering configuration information corresponding to the message content category, the configuration user corresponding to the message content category and the message obtaining status configured by each configuration user are determined, the group members in the group corresponding to the group identifier are obtained, the group members except the configuration message obtaining status that is the rejection status are determined as the receiving members of the message content, and the message content is sent to the receiving users of the receiving members.

If the message content corresponds to a message content category, the non-intersection message acquisition state relationship 401 in fig. 4 may be obtained through the message filtering configuration information corresponding to the message content category, so that after the group members in the group corresponding to the group identifier are acquired according to the group identifier, the group members excluding the reject association user in the group members are determined as the receiving users, and the reject association user is the group member whose configured message acquisition state is the reject state. If the message content of the message corresponds to at least two message content categories, a non-intersection message acquisition state relationship 401 and an intersection message acquisition state relationship 402a or an intersection message acquisition state relationship 402b may be obtained, when the non-intersection message acquisition state relationship 401 is obtained, a group member which is out of the group members of the group corresponding to the group identifier and used for rejecting the association is directly determined as a receiving user of the message content, and the rejecting association user is a group member of which the configured message acquisition state is a rejecting state; when the intersection message obtaining state relationship 402a or the intersection message obtaining state relationship 402b is obtained, a group member other than the reject connection used outdoors in the group members may be determined as a receiving user of the message content, the reject connection associated user is a group member whose configured message obtaining state is the reject connection state, if the intersection message obtaining state relationship 402a shows, a group member other than the reject connection associated user and not the receiving associated user in the group members may also be determined as a receiving user of the message content, the reject connection associated user is a group member whose configured message obtaining state is the reject connection state, the receiving associated user is a group member whose configured message obtaining state is the receiving state, and if the intersection message obtaining state relationship 402b shows. In other words, as shown in fig. 4, the group members other than the group member in the dashed line box among the group members of the group corresponding to the group identifier are determined as the receiving users.

For example, based on the example shown in step S203, it is known that the rejectable associated users corresponding to the message content include "user a, user B, user C, and user D", and the receiving associated users include "user C", as shown in fig. 4, the case shown by the intersection message obtaining status relationship 402a or the intersection message obtaining status relationship 402B is obtained, the receiving user of the message content may be determined according to the intersection message obtaining status relationship 402a, the receiving user of the message content is a group member other than "user a, user B, user C, and user D" in the group member, or the receiving user of the message content may be determined according to the intersection message obtaining status relationship 402B, and the receiving user of the message content is a group member other than "user a, user B, and user D" in the group member.

The method comprises the steps of receiving a message sending request sent by a client, wherein the message sending request comprises a message identifier, a group identifier and message content; acquiring a message filtering configuration information set corresponding to the group identification from the message block chain, wherein the message filtering configuration information set comprises message filtering configuration information associated with a plurality of users and a plurality of message content categories; identifying the message content type corresponding to the message content through a message classification model, and obtaining message filtering configuration information corresponding to the message content type from a message filtering configuration information set; and determining a receiving user of the message content according to the message filtering configuration information corresponding to the message content category, and sending the message content to a receiving terminal of the receiving user. When receiving the group message sent by the client, the group member which is set to receive the group message or not set to reject the group message is determined as the receiving user through each message filtering configuration information which is set by the user in a customized way, the group message is sent to the receiving terminal of the receiving user, so that the group message is filtered in a customized way, invalid messages received by the user through the group are reduced, for example, the user does not receive advertisement and scenery messages when setting the group to receive the advertisement and scenery messages, and when other group members send the advertisement or scenery messages in the group, the server does not send the messages to the user, so that each group member in the group can reduce the number of uninterested or invalid messages received by the group member through the customized message filtering setting, the high efficiency of group message management and the intellectualization and effectiveness of group message sending are improved, thereby improving the searching efficiency of the group message. Meanwhile, a message sending request sent by the client, the determined message content type corresponding to the message content and the like are uploaded to the message block chain, so that the data tampering condition in the message sending process is avoided, the data generated in the message sending process can be traced, and the accuracy of message processing is improved.

Further, referring to fig. 5, fig. 5 is a schematic diagram of a specific flow of message filtering provided in an embodiment of the present application. As shown in fig. 5, the method comprises the following steps:

step S501, target message configuration parameters are obtained.

Specifically, target message configuration parameters received in a target time range are acquired, wherein the target message configuration parameters comprise a configuration user, a group identifier, a target message content category and a target message acquisition state, and the target message configuration parameters carry a digital signature, and the digital signature is obtained by encrypting the target message configuration parameters by the configuration user based on a private key of the configuration user; and generating a message configuration block according to the target message configuration parameters, verifying the message configuration block through a consensus mechanism, and adding the message configuration block into a message block chain if the verification is passed.

Specifically, referring to fig. 6, fig. 6 is a schematic view of a message filtering configuration scenario provided in an embodiment of the present application, a configuration user may click a group to be configured in a message prompt page 601, enter a group session page 602, open a message filtering configuration page 603 of the group through the group session page 602, and input message filtering data including a rejection user and/or a rejection message and/or a reception message in the message filtering configuration page 603, where the rejection user is used to characterize a group member of the configuration user that rejects to receive a message, the rejection message is used to characterize a message content category that the configuration user rejects to receive a message, and the reception message is used to characterize a message content category that the configuration user wants to receive a message. When a client used by a configuration user monitors that the configuration user clicks a submit button in a message filtering configuration page 603, obtaining target message configuration parameters according to message filtering data input by the configuration user, obtaining a private key of the configuration user, encrypting the target message configuration parameters based on the private key to obtain a digital signature, and sending the encrypted target message configuration parameters to any one configuration node 604 in a message filtering system; similarly, other configuration users may also submit message filtering data through the message filtering configuration page 603, and a client used by the other configuration users sends the message filtering data to any one of the configuration nodes 604 in the message filtering system. The configuration node 604 obtains a target message configuration parameter received within a target time range, decrypts the target message configuration parameter through a public key of a configuration user, and obtains a configuration user, a group identifier, a target message content category, and a target message obtaining state included in the target message configuration parameter, where the configuration node 604 may receive a plurality of target message configuration parameters within the target time range, generates a message configuration block 605 according to the obtained target message configuration parameter, verifies the message configuration block 605 through each participating node 606 in the message filtering system based on a common identification mechanism, and if the verification is passed, adds the message configuration block 605 into a message block chain 607, and executes step S502. The content type of the target message and the acquisition state of the target message in the target message configuration parameters are obtained according to the reject message and the received message input by the configuration user, and any group member in the group can query the historical message filtering data configured for the group by the group member through the message filtering configuration page 603. Optionally, if the configuration user inputs the denial user, the target message configuration parameters further include the denial user.

Wherein, the client obtains the target message configuration parameters according to the message filtering data input by the configuration user, as shown in fig. 7, fig. 7 is a schematic diagram of a target message configuration parameter provided in an embodiment of the present application, when the client monitors the message filtering data input by the configuration user, the target message configuration parameters shown in fig. 7 are obtained according to the message filtering data, the target message configuration parameters comprise user identification, group identification and message filtering data input by a configuration user, wherein, the user ID is used to represent the configuration user, the group ID is used to represent that the target message configuration parameter is the message acquisition status configuration for the group corresponding to the group ID, the message filtering data inputted by the configuration user represents the message acquisition status configuration for the group by the user, i.e., the rejection message in the message filtering configuration page 603 and the message content category entered in the received message by the configuration user.

For example, suppose that a user a inputs a denial message "advertisement" and a reception message "food" on a message filtering configuration page 603 of a group 1, a client used by the user a obtains a target message configuration parameter "user a, a group identifier 1 corresponding to the group 1, an advertisement-denial state, a food-reception state" according to data input by the user a, the target message configuration parameter of the user a includes two message acquisition state configurations configured by the user a, and the client used by the user a sends the target message configuration parameter to a message filtering system; a user B inputs a rejection message advertisement on a message filtering configuration page 603 of a group 1, a client used by the user B obtains a target message configuration parameter user B, a group identifier 1 corresponding to the group 1 and an advertisement-rejection state according to data input by the user B, the target message configuration parameter of the user B comprises a message acquisition state configuration configured by the user B, and the client used by the user B sends the target message configuration parameter to a message filtering system; a user C inputs a refusing message 'advertisement' and a receiving message 'landscape' in a message filtering configuration page 603 of a group 1, a client used by the user C obtains a target message configuration parameter 'user C, a group identifier 1 corresponding to the group 1, an advertisement-refusing state and a landscape-receiving state' according to data input by the user C, the target message configuration parameter of the user C comprises two message acquisition state configurations configured by the user C, and the client used by the user C sends the target message configuration parameter to a message filtering system; and so on. The message filtering system acquires target message configuration parameters received in a target time range, generates a message configuration block according to the acquired target message configuration parameters if the target message configuration parameters of the user A, the user B and the user C are received in the target time range, verifies the message configuration block through a consensus mechanism, and adds the message configuration block into a message block chain if the message configuration block passes the verification.

Step S502, generating a message filtering configuration information set.

Specifically, the group identifier is used as an index, and an index relationship between the group identifier and the content category of the target message is established; and associating the content type of the target message with a configuration user, and establishing a corresponding relation between the configuration user and the acquisition state of the target message to generate a message filtering configuration information set corresponding to the group identifier, wherein the acquisition state of the target message is a receiving state or a rejecting state, the receiving state is used for representing the configuration user to receive the message content corresponding to the content type of the target message, and the rejecting state is used for representing the configuration user to reject the state of the message content corresponding to the content type of the target message. Before generating a message filtering configuration information set, acquiring a message filtering configuration information set corresponding to the group identifier, if the message filtering configuration information set exists, directly updating the message filtering configuration information set according to the target message configuration parameter, namely adding data in the acquired target message configuration parameter into the message filtering configuration information set, and specifically determining the adding position of the target message configuration parameter in the message filtering configuration information set through the group identifier in the target message configuration parameter, the content type of the target message and a configuration user; if the message filtering configuration information set corresponding to the group identifier does not exist, generating a message filtering configuration information set according to the incidence relation among all parameters in the target message configuration parameters, wherein a branch line arbitrarily associated in the message filtering configuration information set can determine a complete message filtering data, and the branch line comprises the group identifier, the message content category and the incidence relation among the configuration users. The message filtering configuration information set may be as shown in fig. 3, or may also be as shown in fig. 8, where fig. 8 is another message filtering configuration information set diagram provided in this embodiment of the present application.

For example, if the obtained message filtering configuration information set is as shown in fig. 3, based on the example in step S501, an example graph generated from the message filtering configuration information set as shown in fig. 9a may be obtained, as shown in fig. 9a, the group identifier 1 is used as an index, an index relationship between the group identifier 1 and three message content categories of landscape, advertisement and food is established, it is known that the user a, the user B and the user C configure the message acquisition status of landscape messages, the user C configures the message acquisition status of advertisement messages, the user a configures the message acquisition status of food messages, the landscape is respectively associated with the user a, the user B and the user C, and a corresponding relationship between each configured user and each message acquisition status is established, a message filtering configuration information set as shown in fig. 9a is generated, one branch in the message filtering configuration information set may determine a complete message filtering data, for example, "group id 1-landscape-user a-reject", the message filtering data "user a rejects landscape type messages in the group corresponding to the group id 1" is determined. If the obtained message filtering configuration information set is shown in fig. 8, based on the example in step S501, another message filtering configuration information set generation example shown in fig. 9B may be obtained, as shown in fig. 9B, the group identifier 1 is used as an index, an index relationship between the group identifier 1 and three group members, i.e., the user a, the user B, and the user C, is established, it is known that the user a inputs two message acquisition state configurations, the user B inputs one message acquisition state configuration, the user C inputs two message acquisition state configurations, the user a and the two message acquisition state configurations input by the user a are associated, the user B and the one message acquisition state configuration input by the user B are associated, the user C and the two message acquisition state configurations input by the user C are associated, and a message filtering configuration information set shown in fig. 9B is generated, a branch in the message filtering configuration information set may determine a complete message filtering data, such as "group id 1-user a-configuration 1", and determine the message filtering data "user a rejects the landscape message in the group corresponding to the group id 1".

Step S503, receiving a message sending request sent by the client, where the message sending request includes a message identifier, a group identifier, and a message content.

Specifically, refer to the detailed description shown in step S201 in fig. 2, which is not repeated herein.

Step S504 determines the data type of the message content.

Specifically, the data type of the message content is determined according to the message content in the acquired message sending request, and the data type of the message content includes video messages, image messages, text messages, voice messages, link messages and the like. If the message content is a playable message and has a playing time length, the data type of the message content is a video message; if the message content is a single image, the data type of the message content is an image message; if the message content is a plain text, the data type of the message content is a text message; if the message content is voice, the data type of the message content is voice message; if the message content is clickable message, the data type of the message content is link message and the like. Specifically, the suffix name and the component element of the message content may be extracted, and the data type of the message content may be determined, for example, the data type of the message content with the suffix name of jpg is an image message, the data type of the message content with the suffix name of avi is a video message, the data type of the message content with the component element being a text message, and the data type of the message content with the component element being a hyperlink address is a link message.

Step S505, inputting the data type of the message content into the message classification model to obtain the message content category corresponding to the message content, and obtaining the message filtering configuration information corresponding to the message content category from the message filtering configuration information set.

Specifically, according to the data type of the message content, the message content is input into a corresponding message classification model to obtain a message content category corresponding to the message content category, and then message filtering configuration information corresponding to the message content category is obtained from a message filtering configuration information set. The message classification model includes, but is not limited to, an image classification model, a text classification model, and the like.

Specifically, if the message content is a video message, each video frame in the video message is composed into a combined image; and inputting the combined image into a message classification model to obtain a message content class corresponding to the message content, wherein the used message classification model is an image classification model, and the image classification model is obtained based on an image sample and an image class sample. If the message content is a text message, splitting the text message to obtain a plurality of participles; extracting key participles in the participles according to the parts of speech of the participles, converting the key participles into key participle vectors, inputting the key participle vectors into a message classification model to obtain message content classes corresponding to the message content, wherein the used message classification model is a text classification model, and the text classification model is obtained by training based on a text message sample and a text message class sample. If the message content is a link message, determining the legality of the link message according to the format of the hyperlink address of the link message, if the hyperlink address of the link message cannot be accessed or the format of the hyperlink address is incomplete, sending a link message invalidation prompt to a client, and if the link message is legal, acquiring link data corresponding to the link message, extracting character data in the link data to input the character data into a character classification model, extracting image data or video data in the link data to input the image classification model, and acquiring the message content category corresponding to the message content. If the message content is a voice message, the voice message is converted into a text message, and the message content category corresponding to the voice message is obtained through the classification process of the text message.

Taking a video message as an example, a process of obtaining message filtering configuration information corresponding to the video message specifically refers to fig. 10, and fig. 10 is a schematic view of a video message filtering scene provided in an embodiment of the present application, as shown in fig. 10, when it is determined that the message content is the video message 1001, a video image of each frame constituting the video message 1001 is extracted, the video image of each frame is combined into a combined image 1002, message filtering configuration information corresponding to the video message is obtained through the combined image 1002, and a process of determining the message filtering configuration information of the video message is shown in 1004 in fig. 10. The process 1004 for determining the message filtering configuration information of the video message specifically includes inputting each frame of video image in the combined image into a message classification model respectively to obtain a message content category corresponding to each frame of video image, sorting the message content category corresponding to each frame of image to obtain a message content category corresponding to the video message, and obtaining the message filtering configuration information corresponding to the video message from a message filtering configuration information set according to the message content category corresponding to the video message, specifically obtaining the message filtering configuration information corresponding to the video message according to "video message- > message content category- > message filtering configuration information". Wherein, in the process 1004 for determining the message filtering configuration information of the video message, the message content categories corresponding to each frame image are sorted, and the message content categories corresponding to each frame image are deduplicated so that no repeated message content categories appear in the message content categories corresponding to the finally obtained video message, optionally, the message content categories corresponding to each frame image can be weighted to obtain the message content categories corresponding to the video image, for example, smaller weights are added to the message content categories at the start position and the end position of the video message, larger weights are added to the middle position of the video message, the message content categories corresponding to each frame image are weighted to obtain the final weight of each message content category, and the message content category with the weight larger than a preset weight threshold or p message content categories with the largest weight are determined as the message content categories corresponding to the video content, p is a positive integer, and p is a preset number of categories. If the message content is an image message, the image message is directly input into the image classification model, and the message content category corresponding to the image message is obtained.

If the message filtering configuration information set is as shown in fig. 3, after determining the message content type corresponding to the message content, the message filtering configuration information corresponding to the message content is determined directly according to the association relationship between the message content type in the message filtering configuration information set and the configuration user, the content type description, and the like. If the message filtering configuration information set is as shown in fig. 8, after determining the message content category corresponding to the message content, acquiring the user identifier associated with the message content category and the message acquisition state corresponding to the message content category in the configuration, and determining the message filtering configuration information corresponding to the message content according to the user identifier associated with the message content category and the message acquisition state corresponding to the message content category; or, after determining the message content category corresponding to the message content, acquiring a user identifier associated with the message content category, in the structure shown in fig. 8, acquiring adjacent node data, previous node data, and the like of the message content category, and recording the acquired data associated with the message content category through the structure shown in fig. 3, thereby determining the message filtering configuration information corresponding to the message content, for example, after obtaining the message content category 2, acquiring data associated with the message content category 2, including data in configuration 1 of user identifier 2 and user identifier 2 in the message filtering configuration information set with group identifier 1 as an index, and recording data associated with the message content category 2 through the structure shown in fig. 3, thereby obtaining "group identifier 1-message content category 2-user identifier 2-message acquiring state", thereby obtaining the message filtering configuration information corresponding to the message content category 2.

Step S506, a message filtering block is generated according to the message filtering configuration information, and the message filtering block is uploaded to the message block chain.

Specifically, the message sending request further comprises a sending user, and a block to be verified is generated according to the group identifier, the sending user, the message content and the message filtering configuration information corresponding to the message content category; and verifying the block to be verified according to a consensus mechanism, if the block to be verified passes the verification, generating a message filtering block according to the block to be verified and the message block chain, and adding the message filtering block into the message block chain.

Based on the example shown in step S203 in fig. 2, knowing that the group identifier is the group identifier 1, the sending user is the user a, the message content is an image, the message content category is "landscape and advertisement", the message filtering configuration information "number ID1 corresponding to the message content category" landscape "indicates that the user is configured with a message such as a landscape-only image, text, or link: refusing by user A, refusing by user B and receiving by user C, message filtering configuration information ' number ID2 corresponding to message content type ' advertisement ', message of content type description-advertisement type image, text or link, etc., configuring user: and if the user C refuses the connection and the user D refuses the connection, generating a to-be-verified block according to the information filtering configuration information corresponding to the group identifier 1, the user A, the image and the landscape and the information filtering configuration information corresponding to the advertisement, carrying out consensus verification on the to-be-verified block, generating an information filtering block according to the to-be-verified block and the information block chain, and adding the information filtering block into the information block chain.

Step S507, determining a receiving user of the message content, and sending the message content to a receiving terminal of the receiving user.

Specifically, message filtering configuration information corresponding to a message content category is obtained, and a plurality of associated users associated with the message content category are obtained based on the message filtering configuration information; determining the message acquisition state of each associated user for the message content category based on the message filtering configuration information, and determining the associated user with the message acquisition state as a rejection associated user in the plurality of associated users, wherein the rejection state is the state of rejecting the message content corresponding to the message content category; and acquiring the group members in the group corresponding to the group identification, and determining the outdoor group members for excluding the switch in the group members as receiving users of the message content. The specific receiving user determination process can be referred to as the specific description in step S204 in fig. 2. The receiving user 1005 shown in fig. 10 may be participated in, obtain a group member in the group corresponding to the group identifier through the group identifier, determine a rejection associated user "group member 2, …, and group member m" in the group member, determine a group member other than the rejection associated user in the group member as a receiving user of the message content, and send the message content to a receiving terminal of the receiving user. If the receiving user comprises the sending user, the message content is not sent to the receiving terminal of the sending user when the message content is sent to the receiving terminal of the receiving user.

Step S508, obtaining a message filtering result sent by the receiving terminal, and if the message filtering result is a message filtering abnormal result, updating the message classification model.

Specifically, a message filtering result sent by a receiving terminal is obtained, a filtering result block is generated according to the message filtering result, and the filtering result block is uploaded to a message block chain; the message filtering result is used for representing the accuracy of the filtering result fed back by the receiving terminal aiming at the message content, and the message filtering result comprises a message filtering abnormal result or a message filtering normal result; and if the message filtering result is a message filtering abnormal result, adjusting the class label of the message content according to the message filtering abnormal result, and updating the message classification model according to the message content and the adjusted class label. The message filtering result comprises message content, a message content category corresponding to the message content and a receiving result of the message content. Specifically, when a group member receives a message content, the group member finds that the message content belongs to a message content type of a rejection state configured by the group member, and sends a message filtering result to a message filtering system through a receiving terminal, after the message filtering system obtains the message filtering result, the message content type in the message filtering result is used as a type label of the message content, and the type label and the message content are input into a message classification model for training, so that the message classification model is updated; or when the group member knows that a message content which the group member should receive is not sent to the receiving terminal of the group member, the group member sends a message filtering result to the message filtering system through the receiving terminal, and the message filtering system updates the message classification model through the message filtering result.

Optionally, after obtaining the message filtering configuration information corresponding to a certain message content, obtaining multiple associated users associated with the message content category based on the message filtering configuration information, determining the message obtaining states of the multiple associated users for the message content category based on the message filtering configuration information, if there is a receiving associated user whose message obtaining state is a receiving state among the multiple associated users, when sending the message content to a receiving terminal of the receiving user, prompting the receiving associated user, for example, if the user C is the receiving associated user, when sending the message content to the receiving terminal of the user C, a prompting message for the user C, such as "@ user C", may be added, so that the user may obtain the message content of the own key attention in time.
