Abstract

An instant messaging message processing method is disclosed and includes: receiving, by a server, an instant messaging message, user account information of a destination user terminal, and user account information of a source user terminal from the source user terminal; determining, by the server, a risk level of the instant messaging message according to a preset rule and the user account information of the source user terminal; and if the risk level of the instant messaging message reaches a first risk level, transmitting, by the server when, the instant messaging message and preset pre-warning information to the destination user terminal according to the user account information of the destination user terminal, wherein the pre-warning information comprises security prompt information which is used for prompting a user of the destination user terminal to notice a security risk of the instant messaging message. An instant messaging message processing device is also disclosed.

First claim

The invention claimed is:

1. An instant messaging message processing method, comprising:
receiving, by a server, an instant messaging message, user account information of a destination user terminal, and user account information of a source user terminal from the source user terminal, the source user terminal and the destination user terminal each comprising at least one processor executing an instant messaging application;
determining, by the server, a risk level of the instant messaging message according to content of the instant messaging message and the user account information of the source user terminal; and
after the server determines that the risk level of the instant messaging message reaches a first risk level, transmitting, by the server, the instant messaging message along with a pre-warning information to the destination user terminal according to the user account information of the destination user terminal,
wherein:
the pre-warning information is displayed by the instant messaging application on the destination user terminal, and comprises security prompt information and verification information,
the verification information is displayed as a selectable control in the instant messaging application on the destination user terminal, and when the selectable control is selected, the destination user terminal is triggered to perform one of: sending a verification request to the server for conducting identity verification with the source user terminal or invoking a dialing function for making a telephone call to the source user terminal, and
determining, by the server, the risk level of the instant messaging message further comprises:
identifying, by the server, whether the source user terminal exhibits one or more preset type of event based on a user account of the source user terminal, user behavior trajectory information corresponding to the user account, and identity information of the source user terminal to obtain a first analysis result, wherein when the one or more preset type of event is identified, the first analysis result is generated based on preset weight information corresponding to the one or more identified preset type of event; and
determining, by the server, the risk level of the instant messaging message based on the first analysis result.

2. The method according to claim 1 , wherein determining by the server a risk level of the instant messaging message according to content of the instant messaging message and the user account information of the source user terminal comprises:
analyzing, by the server, the content of the instant messaging message according to a preset analysis rule to obtain a second analysis result;

determining, by the server, the risk level of the instant messaging message based on a combination of the first analysis result and the second analysis result.

3. The method according to claim 1 , wherein,
the identity information of the source user terminal obtained by the server for determining the risk level comprises one of or any combination of at least two of: an IP address, a machine identification code, and a MAC address of the source user terminal.

4. The method according to claim 2 , wherein the analyzing by the server the content of the instant messaging message according to a preset analysis rule to obtain a second analysis result comprises:
matching, by the server, the content of the instant messaging message with a plurality of preset keywords and determining whether at least one preset keyword is comprised in the instant messaging message, to obtain the second analysis result,
wherein when the at least one preset keyword is found in the content, the second analysis result is generated based on preset weight information corresponding to the at least one matched preset keyword included in the content.

5. The method according to claim 3 , wherein, the user behavior trajectory information comprises one of or any combination of: a common location of the login of the user account by the user, an identifier of a user terminal commonly used by the user for the login of the user account, a theft record of the user account, and a violative information release record of the user account.

6. The method according to claim 1 , further comprising:
if the risk level of the instant messaging message reaches a second risk level, forwarding, by the server, the instant messaging message to the destination user terminal without the preset pre-warning information according to the user account information of the destination user terminal.

7. The method according to claim 1 , wherein, the pre-warning information further comprises report information; and the report information is used for allowing the destination user terminal to report, according to a preset report approach, the instant messaging message as per a corresponding user operation.

8. The method according to claim 1 , further comprising:
receiving, by the server, the verification request from the destination user terminal;
transmitting, by the server, an identity verification question to the source user terminal, the identity verification question being preset by the user account of the destination user terminal;
receiving, by the server, an answer returned by the source user terminal; and
verifying the source terminal by determining whether the answer is correct.

9. The method according to claim 8 , wherein:
a correct answer corresponding to the identity verification question is preset by the user account of the destination user terminal and saved on the server, and the server determines whether the answer from the source user terminal is correct based on the preset correct answer; or
the server transmits the answer to the destination user terminal for a user of the destination user terminal to determine whether the answer is correct.

10. The method according to claim 1 , wherein:
the user behavior trajectory information corresponding to the user account includes an identifier of a user terminal commonly used for login of the user account with the instant messaging application; and
the one or more preset type of event includes: the identity information of the source user terminal is different from the identifier of the user terminal commonly used for login of the user account with the instant messaging application.

11. The method according to claim 1 , wherein transmitting the instant messaging message along with the pre-warning information further comprises:
determining, by the server, the verification information based on a type of the destination user terminal;
when the destination user terminal is a mobile phone, transmitting the verification information configured for invoking the dialing function;
when the destination user terminal is a computer, transmitting the verification information configured for sending the verification request.

12. An instant messaging message processing method, comprising:
receiving, by a destination user terminal comprising at least one processor executing an instant messaging application, an instant messaging message and pre-warning information from a server, wherein the pre-warning information comprises security prompt information, verification information and report information, and the security prompt information is used for prompting a user of the destination user terminal to notice a security risk of the instant messaging message;
presenting, by the destination user terminal, the instant messaging message and the pre-warning information to the user; and
performing a corresponding operation, by the destination user terminal, in response to an operation performed by the user according to the verification i
