Description

A filtering method and instant messaging system for instant messaging messages

technical field

The invention belongs to the field of instant messaging, in particular to a method and system for receiving and managing user messages in instant messaging.

Background technique

Internet instant messaging (Instant Messenger, referred to as IM) is a communication service based on the Internet. Therefore, higher and higher requirements are placed on the security of user communication. In the process of instant messaging for users, the sending and receiving of instant messaging messages is the most important means of communication, and users maintain efficient information exchanges with other users through this simple sending and receiving of messages. However, the user often receives some illegal and boring messages from other users, causing unnecessary interference to the user, so it is necessary to block the messages of other users accordingly.

The current way to block user messages is that the user can set not to receive messages from a certain user at all. When the user receives a message from a blocked user, the user's message is directly discarded without displaying and saving. Because this scheme completely prevents receiving a certain user's message, it cannot selectively receive according to the content of the user's message, so that the user lacks sufficient flexibility in the management of message receiving.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention filters the message according to the content of the instant messaging message. If the received message content contains the blocked content set by the user, the message is not received and is directly discarded. If the received message content does not contain the blocked content set by the user , the user is prompted to receive the friend message.

Fig. 1 shows the network structure of the instant messaging system applicable to the present invention, and multiple instant messaging clients are connected to the instant messaging server. The instant messaging server stores user information of instant messaging users, such as instant messaging numbers, user names, and login passwords, and friend information of instant messaging users, such as instant messaging numbers and user names of friends. The instant messaging client is loaded with the instant messaging client subsystem. The user logs in to the instant messaging server through the instant messaging client and performs identity verification. After the identity verification is passed, the user performs point-to-point communication with other users through the instant messaging client And receive instant messaging messages and data, etc.

Figure 2 shows the implementation process of setting message filtering field information:

1. The instant messaging user sets the instant messaging number to be filtered, and the filtering content corresponding to the instant messaging number is saved in the local message filtering database.

In the present invention, the user can set one or more message filtering field information for a certain instant messaging number, and the message filtering fields are separated by a field separator, such as ";". Of course, the user can also set to filter all instant messaging messages from a certain instant messaging number, that is, to completely block messages from a certain user.

2. The instant messaging client combines the set instant messaging number that needs to be filtered, the corresponding message filtering field information, and the user's instant messaging number into the data packet, encrypts the data packet, and uses the IP agreed upon with the instant messaging server. The address and PORT port generate a sending socket, and send the encrypted data packet to the instant messaging server.

3. After the instant messaging server receives the data packet asynchronously through the agreed socket, it decrypts it. After confirming that it is a valid data packet, it parses out the instant messaging number that needs to be filtered and the corresponding message filtering field information in the data packet, and puts it into Saved in the user information database, it is used for users to log in to the system at different locations to obtain message filtering information.

The user can modify or cancel the filtering of messages from a certain instant messaging number as required, and resubmit to the instant messaging server for storage.

Fig. 3 shows the implementation process of filtering instant messaging messages, detailed as follows:

In step S301, the user asynchronously waits for the message data packet sent by other users at the agreed message receiving socket, and performs decryption operation after receiving the message data packet, and uses the agreed protocol format to parse out the data packet after judging that it is a valid data packet The instant messaging number and message content in the message;

In step S302, use the instant messaging number corresponding to the extracted message to query the local message filtering database, obtain the message filtering field information corresponding to the instant messaging number, decompose the message filtering field information, and obtain the message filtering string array. The specific decomposition process can be to record the current starting position data, find the field separator, such as ";", and the current position data, cut through the starting position and current position data, and obtain a certain message filtering field for current message filtering, Through loop processing, save the cut result character subset into the message filter string array;

In step S303, traverse the string array list established in step S302, and analyze whether the message content contains a certain message filter string in the character array list, if it does, it means that the message content needs to be filtered, and step S304 is executed , otherwise execute step S305. The extraction and analysis of the message filtering field in the message content can be realized by using the character operation API function of windows.

In step S304, the instant messaging message is directly discarded, and no subsequent processing is performed;

In step S305, the user is prompted to receive the message.

The present invention can be used in combination with existing message filtering schemes, that is, when an instant messaging message is received, it is first judged whether the user who sent the message belongs to a blocked user, and if so, the message is directly discarded; otherwise, the message is processed in the above-mentioned manner The content is filtered and judged.

Fig. 4 shows the structure of the instant messaging system provided by the present invention, and for the convenience of description, only the parts related to the present invention are shown.

The instant messaging system 400 is set on the instant messaging client and includes a message filtering field setting module 401 , a message filtering database 402 , a message sending and receiving module 403 , a message filtering field decomposition module 404 , a message filtering module 405 and a message notification module 406 .

The message filtering field setting module 401 is used to set message filtering field information for a specific instant messaging user.

The message filtering database 402 saves the set message filtering field information, which can be indexed by instant messaging identifiers, such as instant messaging numbers or usernames of instant messaging users.

The message sending and receiving module 403 receives IM messages sent by other IM users, or sends IM messages to other IM users. At the same time, the set message filtering field information is sent to the instant messaging server through the message transceiving module 403 for storage.

After receiving the instant messaging message, the message filtering field decomposition module 404 queries the message filtering database 402, retrieves the message filtering field information of the user corresponding to the instant messaging message, decomposes the message filtering field information, and generates a message filtering character array of strings. The message filtering module 405 filters the received instant messaging message content according to the message filtering string array provided by the message filtering field decomposing module 404, and judges whether the instant messaging message content contains a character string that needs to be filtered, and if so, discards the instant messaging Otherwise, the message notification module 406 prompts the user to receive the instant messaging message.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
