Description

Technical Field

[0001] The present invention relates to the technical field of instant messaging, and in particular to a secure instant messaging method, system and device for preventing information leakage. Background Art

[0002] With the rapid development of Internet technology, instant messaging, as an important communication channel, is widely used in personal social interaction, business communication, education and learning, customer service, etc., and has become an indispensable part of daily life and work. However, while enjoying the many benefits it brings, it also often faces the risk of information leakage. In the process of instant messaging, such a scenario of information leakage often occurs, where key chat records are viewed, screenshotted, photographed, etc. by others, resulting in information leakage. When people use instant messaging in their daily life and work, they do not want sensitive or key chat information such as account numbers and business plans to be known by others. Existing instant messaging tools usually have the following solutions to deal with the above information leakage scenarios:

[0003] (1) Provide a function to delete historical messages, which can clear the entire conversation containing key information or delete key information in the conversation, thereby preventing information leakage;

[0004] (2) Provide a self-destructing function. Self-destructing is a common privacy protection measure that aims to ensure that the content of the sent message is viewed within a limited time and is automatically destroyed.

[0005] The deletion of messages is prone to forgetting to clean up messages in time, leading to information leakage. The time limit of "burn after reading" may affect the reading experience, especially when they need to spend more time to view or understand the content of the message. Moreover, whether it is the deletion of messages or the burn after reading function, the message cannot be retrieved again, which is not suitable for situations that need to be archived or memorized. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a secure instant messaging method, system and device for preventing information leakage, which can effectively avoid the leakage of sensitive messages in instant messaging and provide convenient operation.

[0007] First aspect

[0008] The present invention provides a secure instant messaging method for preventing information leakage, comprising the following steps:

[0009] Step S1, when preparing to send an anti-leakage message, determine whether the current chat mode is an anti-leakage chat mode, if so, edit the anti-leakage message, encrypt the anti-leakage message through the anti-leakage message controller and send it to the message recipient, otherwise, after verification using a custom password controller, enter the anti-leakage module, convert the ordinary chat mode to the anti-leakage chat mode, edit the anti-leakage message, encrypt the anti-leakage message through the anti-leakage message controller and send it to the message recipient;

[0010] Step S2: When the message recipient receives the anti-leakage message, the anti-leakage message controller notifies the anti-leakage message and determines whether the current chat mode is the anti-leakage chat mode. If so, the anti-leakage message controller decrypts the anti-leakage message and displays it through the anti-leakage chat module. Otherwise, after the message recipient uses the custom password controller for verification, the anti-leakage message controller decrypts all anti-leakage messages and displays them through the anti-leakage chat module.

[0011] Step S3: exit the anti-leakage chat mode through the anti-leakage exit controller and hide all anti-leakage messages.

[0012] Furthermore, the step S2 also includes: selecting any common message sent before and converting it into an anti-leakage message.

[0013] Furthermore, the password controller accepts a user-defined verification method to enter the anti-leakage chat module, and the customized verification method includes fingerprint or specific ciphertext. If a specific ciphertext is used as the verification method, verification is performed by directly entering a preset ciphertext in the user conversation box.

[0014] Furthermore, the anti-leakage message controller accepts user-defined anti-leakage message notification methods, including anti-leakage message specific sounds and anti-leakage message notification specific display content, so as to distinguish it from ordinary message notifications and avoid leaking anti-leakage messages from message notifications.

[0015] Furthermore, the anti-leakage chat module enters after verification by the secret command controller, and the anti-leakage mode icon is displayed on the chat interface in the anti-leakage chat mode, and the anti-leakage information hidden in the conversation is displayed. Normal message sending and receiving are performed in this mode, and all messages sent in this mode are anti-leakage messages. All anti-leakage information is marked with specific icons to distinguish between ordinary information and anti-leakage information, and after exiting the anti-leakage chat mode, the anti-leakage mode icon and anti-leakage messages are hidden at the same time, and only ordinary messages are displayed.

[0016] Furthermore, the exit conditions of the anti-leakage exit controller are user-defined, including leaving the chat session, no operation for a set time, and entering the operating system screen saver. The anti-leakage exit controller makes a judgment based on the user-defined settings and automatically exits the anti-leakage chat mode when the conditions are met.

[0017] Furthermore, the anti-leakage message includes text, pictures and videos.

[0018] Second aspect

[0019] The present invention provides a secure instant messaging system for preventing information leakage, comprising:

[0020] The anti-leakage message sending module is used to determine whether the current chat mode is the anti-leakage chat mode when preparing to send the anti-leakage message. If so, the anti-leakage message is edited, the anti-leakage message is encrypted through the anti-leakage message controller and sent to the message recipient. Otherwise, after verification using the custom password controller, the anti-leakage module is entered to convert the ordinary chat mode to the anti-leakage chat mode, the anti-leakage message is edited, the anti-leakage message is encrypted through the anti-leakage message controller and sent to the message recipient.

[0021] The anti-leakage message receiving module is used for the anti-leakage message controller to notify the message recipient of the anti-leakage message when the message recipient receives the anti-leakage message, and at the same time determine whether the current chat mode is the anti-leakage chat mode. If so, the anti-leakage message controller decrypts the anti-leakage message and displays it through the anti-leakage chat module. Otherwise, after the message recipient uses the custom password controller for verification, the anti-leakage message controller decrypts all anti-leakage messages and displays them through the anti-leakage chat module.

[0022] The anti-leakage exit module is used to exit the anti-leakage chat mode through the anti-leakage exit controller and hide all anti-leakage messages.

[0023] Furthermore, the anti-leakage chat module also includes: a module for selecting any common message sent before and converting it into an anti-leakage message.

[0024] Furthermore, the password controller accepts a user-defined verification method to enter the anti-leakage chat module, and the customized verification method includes fingerprint or specific ciphertext. If a specific ciphertext is used as the verification method, verification is performed by directly entering a preset ciphertext in the user conversation box.

[0025] Furthermore, the anti-leakage message controller accepts user-defined anti-leakage message notification methods, including anti-leakage message specific sounds and anti-leakage message notification specific display content, so as to distinguish it from ordinary message notifications and avoid leaking anti-leakage messages from message notifications.

[0026] Furthermore, the exit conditions of the anti-leakage exit controller are user-defined, including leaving the chat session, no operation for a set time, and entering the operating system screen saver. The anti-leakage exit controller makes a judgment based on the user-defined settings and automatically exits the anti-leakage chat mode when the conditions are met.

[0027] Furthermore, the anti-leakage chat module enters after verification by the secret command controller, and the anti-leakage mode icon is displayed on the chat interface in the anti-leakage chat mode, and the anti-leakage information hidden in the conversation is displayed. Normal message sending and receiving are performed in this mode, and all messages sent in this mode are anti-leakage messages. All anti-leakage information is marked with specific icons to distinguish between ordinary information and anti-leakage information, and after exiting the anti-leakage chat mode, the anti-leakage mode icon and anti-leakage messages are hidden at the same time, and only ordinary messages are displayed.

[0028] Furthermore, the anti-leakage message includes text, pictures and videos.

[0029] The advantages of the present invention are: compared with the functions of self-destructing and deleting information, the method of the present invention can prevent information leakage while storing it for a long time, and can be well adapted to situations where archiving or memos are required. In addition, convenient switching of modes is achieved through customized commands and customized exit conditions, thereby improving user operating experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The embodiment of the present application provides a secure instant messaging method, system and device to prevent information leakage, which is used to solve the problem of messages being read and leaked by others in existing instant messaging. The technical solution in the embodiment of the present application has the following general idea: messages are divided into two categories: ordinary messages and anti-leakage messages, each of which can be text, pictures, videos and other information, and the anti-leakage messages are interacted and hidden through the pre-made command controller, anti-leakage chat module, anti-leakage message controller and anti-leakage exit controller.

[0036] In order to make the present invention more clearly understood, a preferred embodiment is now described in detail with reference to the accompanying drawings.

[0037] Embodiment 1

[0038] like Figure 1 As shown, the present invention provides a secure instant messaging method for preventing information leakage, comprising the following steps:

[0039] Step S1, when preparing to send an anti-leakage message, determine whether the current chat mode is an anti-leakage chat mode, if so, edit the anti-leakage message, encrypt the anti-leakage message through the anti-leakage message controller and send it to the message recipient, otherwise, after verification using a custom password controller, enter the anti-leakage module, convert the ordinary chat mode to the anti-leakage chat mode, edit the anti-leakage message, encrypt the anti-leakage message through the anti-leakage message controller and send it to the message recipient;

[0040] Step S2: When the message recipient receives the anti-leakage message, the anti-leakage message controller notifies the anti-leakage message and determines whether the current chat mode is the anti-leakage chat mode. If so, the anti-leakage message controller decrypts the anti-leakage message and displays it through the anti-leakage chat module. Otherwise, after the message recipient uses the custom password controller for verification, the anti-leakage message controller decrypts all anti-leakage messages and displays them through the anti-leakage chat module.

[0041] Step S3: exit the anti-leakage chat mode through the anti-leakage exit controller and hide all anti-leakage messages.

[0042] The normal chat mode is the system default chat mode.

[0043] Preferably, the step S2 further comprises: selecting any common message sent before and converting it into an anti-leakage message.

[0044] Preferably, the password controller accepts a user-defined verification method to enter the anti-leakage chat module, and the customized verification method includes fingerprint or specific ciphertext. If the specific ciphertext is used as the verification method, the verification is performed by directly inputting the preset ciphertext in the user session box. For example, it is preset to start the anti-leakage chat module in the form of a password and set the password to aaaaaa. When aaaaaa is sent during the chat, the anti-leakage chat mode is entered. If the fingerprint verification method is set, the anti-leakage chat module is automatically started when the preset fingerprint is input during the chat, and the current chat mode is changed from the normal mode to the anti-leakage chat mode.

[0045] Preferably, the anti-leakage message controller accepts user-defined anti-leakage message notification methods, including anti-leakage message specific sounds and anti-leakage message notification specific display content, so as to distinguish it from ordinary message notifications and avoid the message notification from leaking anti-leakage messages. At the same time, the anti-leakage message controller can perform additional encryption and decryption on the anti-leakage message, such as the national secret SM4.

[0046] Preferably, the anti-leakage chat module is entered after verification by the password controller, and the anti-leakage mode icon is displayed on the chat interface in the anti-leakage chat mode, and the anti-leakage information hidden in the conversation is displayed. Normal message sending and receiving are carried out in this mode, and the messages sent in this mode are all anti-leakage messages. All anti-leakage information is marked with specific icons to distinguish between ordinary information and anti-leakage information, and after exiting the anti-leakage chat mode, the anti-leakage mode icon and anti-leakage messages are hidden at the same time, and only ordinary messages are displayed.

[0047] Preferably, the exit condition of the anti-leakage exit controller is user-defined, including leaving the chat session, no operation for a set time, entering the operating system screen saver, etc. The above conditions can be combined arbitrarily. The anti-leakage exit controller will make a judgment based on the settings and automatically exit the anti-leakage chat mode when the conditions are met.

[0048] Preferably, the anti-leakage message includes text, pictures and videos.

[0049] like Figure 4As shown, when user A and user B communicate, user A and user B set their own secret codes and message notification methods according to their own preferences. Then, when user A needs to send or receive an anti-leakage message, the preset secret code is input by default. After the secret code controller is successfully verified, the anti-leakage chat mode is entered. In this mode, the anti-leakage mode icon is displayed, and the hidden anti-leakage message in the session is displayed. The anti-leakage message is sent and received. The anti-leakage message is sent to the anti-leakage message controller of user B after the anti-leakage message control. The anti-leakage message controller of user B determines whether the current mode of user B is the anti-leakage chat mode. If so, it is displayed on the anti-leakage chat mode interface of user B. Otherwise, user B is reminded to enter the secret code. After verification by the secret code controller, the anti-leakage chat module is entered, the anti-leakage mode is turned on and the anti-leakage mode icon is displayed, the hidden information of the session is displayed, the anti-leakage information is received and sent until the anti-leakage exit controller exits the anti-leakage chat module, all anti-leakage information in the session is hidden, and only ordinary information is displayed to avoid the leakage of anti-leakage messages.

Otherwise, after verification using the custom password controller, the anti-leakage module is entered to convert the ordinary chat mode to the anti-leakage chat mode, the anti-leakage message is edited, the anti-leakage message is encrypted through the anti-leakage message controller and sent to the message recipient.

[0054] The anti-leakage message receiving module is used for the anti-leakage message controller to notify the anti-leakage information when the message recipient receives the anti-leakage message, and at the same time determine whether the current chat mode is the anti-leakage chat mode.

Normal message sending and receiving are carried out in this mode, and the messages sent in this mode are all anti-leakage messages. All anti-leakage information is marked with specific icons to distinguish between ordinary information and anti-leakage information, and after exiting the anti-leakage chat mode, the anti-leakage mode icon and anti-leakage messages are hidden at the same time, and only ordinary messages are displayed.

[0061] The anti-leakage chat module is used to display the anti-leakage mode icon in the chat interface under the anti-leakage chat mode, and to display the anti-leakage information hidden in the conversation. Normal message sending and receiving are performed in this mode, and all messages sent in this mode are anti-leakage messages.
