Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Fig. 1 exemplarily shows a flowchart of a file processing method based on an instant chat tool, which can be at least in the field of communication technologies. As shown in fig. 1, the method for processing files based on instant chat tool mainly includes the following steps:
and 102, receiving a first secret key corresponding to the secret opening mode information fed back by the server, adding the first secret key into a first file to be transmitted to form a first secret file, transmitting the first secret file to a second terminal, so that the second terminal obtains the first secret key from the server after receiving the first secret file, and decrypting the first secret file according to the first secret key to obtain the first file to be transmitted.
It should be noted that the main execution body in the foregoing embodiment is the first terminal, where the first terminal interacts with the second terminal through the server.
In step 101, when the first terminal needs to send a file to the second terminal, and the sent file content relates to some confidential content, the first terminal sends the secret opening mode information to the server electrically connected to the first terminal before sending the file to the second terminal, where the secret opening mode information carries an ID of the first terminal, and based on this, the server may feed back the first key to the first terminal.
In step 102, the first secret key fed back by the server and received by the first terminal confirms that the first secret key corresponds to the secret opening mode information sent by the first terminal, that is, the first secret key is fed back to the first terminal by the server for the secret opening mode information.
The first terminal stores the first key in a set area, so that the first key can be conveniently used in subsequent file transmission with the second terminal. Further, after confirming the first file to be transmitted to the second terminal, the first terminal adds the first key to the first file to be transmitted, the first file to be transmitted and the first key form a first secret file, and the first terminal transmits the first secret file to the second terminal.
In the embodiment of the present invention, after the second terminal receives the first confidential document sent by the first terminal, the first confidential document cannot be directly displayed on the second terminal because the first confidential document includes the first key.
Further, after receiving the first confidential file, the second terminal needs to obtain a first key corresponding to the first confidential file from the server, and obtain the first file to be transmitted, which is transmitted by the first terminal, from the first confidential file based on the first key. Specifically, the second terminal sends the ID of the second terminal to the server, and after receiving the ID of the second terminal sent by the second terminal, the server finds the first key matched with the ID of the second terminal according to the secret opening mode information stored in the system, and sends the first key to the second terminal.
It should be noted that, when the first terminal sends the secret opening mode information to the server, the information carries the ID of the first terminal and the ID of the second terminal, and the server determines the first key according to the secret opening mode information, and then stores the first key, the ID of the first terminal, the ID of the second terminal, and the secret opening mode information in the set area.
And after receiving the first secret key sent by the server, the second terminal decrypts the first confidential file, so that a first file to be sent, which is sent to the second terminal by the first terminal, can be obtained.
Further, after the interface of the second terminal displays the first file to be transmitted, if the first file to be transmitted needs to be stored in the second terminal, the second terminal may download the first file to be transmitted and then store the first file to be transmitted in the second terminal.
Based on the above flow, the first terminal completes the process of sending the confidential document to the second terminal.
It should be noted that, in practical applications, if the second terminal needs to display the first to-be-transmitted file received by the second terminal to the third terminal after the second terminal receives the first to-be-transmitted file transmitted by the first terminal and after the worker leaves the working location of the second terminal, the third terminal is not included in the first key stored in the server, the ID of the first terminal, the ID of the second terminal, and the secret opening mode information, and therefore the first to-be-transmitted file cannot be displayed on the third terminal. In the embodiment of the present invention, the device authorization information is sent to the second terminal by the third terminal, and after receiving the device authorization information, the second terminal may send the first key obtained from the server to the third terminal. After the third terminal receives the first secret key sent by the second terminal, the first confidential file can be decrypted, and therefore the first file to be sent is displayed on the third terminal.
Fig. 2 exemplarily shows a flowchart of another file processing method based on an instant chat tool according to an embodiment of the present invention, and as shown in fig. 2, the file processing method based on the instant chat tool mainly includes the following steps:
It should be noted that the main execution body in the foregoing embodiment is the second terminal, where the second terminal interacts with the first terminal through the server.
In step 201, the second terminal receives the first secret file sent by the first terminal, and the first secret file cannot be directly displayed on the second terminal because the first secret file includes the first key. Further, the second terminal needs to obtain a first key corresponding to the first confidential document from the server, where the first key is a key used when the second terminal and the first terminal perform interaction.
And after receiving the ID of the second terminal sent by the second terminal, the server finds a first secret key matched with the ID of the second terminal according to the secret opening mode information stored in the system and sends the first secret key to the second terminal.
It should be noted that, before the second terminal receives the first confidential document sent by the first terminal, because the first terminal confirms that the file sent to the second terminal relates to some confidential contents, before the first confidential document is sent to the second terminal, the first terminal sends the secret opening mode information to the server electrically connected to the first terminal, where the secret opening mode information carries the ID of the first terminal and the ID of the second terminal.
When the server receives the secret opening mode information sent by the first terminal and the ID of the second terminal carried in the information, a first secret key is generated according to the information, and then the secret opening mode information, the ID of the first terminal, the ID of the second terminal and the first secret key are stored in a set area of the server.
After receiving the first key fed back by the server, the first terminal adds the first key into a first file to be sent, which needs to be sent to the second terminal, and the first key and the first file to be sent form a first confidential file.
Based on this, after the second terminal sends the ID of the second terminal to the server, the server feeds back the first key to the second terminal.
In step 202, after the second terminal receives the first key sent by the server, the first encrypted file may be decrypted according to the first key, so as to obtain a first file to be sent, which is sent by the first terminal to the second terminal.
It should be noted that, when the first terminal sends the first file to be sent to the second terminal, and the second terminal has decrypted the first file to be sent, the first terminal and the second terminal complete the session.
In practical application, if the second terminal receives the first to-be-transmitted file sent by the first terminal, and the worker leaves the working position of the second terminal and needs to display the first to-be-transmitted file received by the second terminal to the third terminal, the third terminal cannot display the first to-be-transmitted file because the third terminal is not included in the first secret key, the ID of the first terminal, the ID of the second terminal and the secret opening mode information stored in the server. In the embodiment of the present invention, the device authorization information is sent to the second terminal by the third terminal, and after receiving the device authorization information, the second terminal may send the first key obtained from the server to the third terminal. After receiving the first key sent by the second terminal, the third terminal can decrypt the first encrypted file, so that the first file to be sent is displayed on the third terminal.
In order to more clearly describe the file processing method based on the instant chat tool provided by the embodiment of the present invention, the file processing method based on the instant chat tool is described in detail below with reference to fig. 3.
Fig. 3 is a schematic flow chart of a confidential chat mode according to an embodiment of the present invention, and as shown in fig. 3, the confidential chat mode includes a user a, a user C, a server B, and a server D. Specifically, the method comprises the following steps:
step 301, before sending a file to a user C, a user a determines to select a secret mode, and sends secret mode opening information to a server D, where the secret mode opening information carries an ID of a terminal where the user a is located and an ID of a terminal where the user C is located.
Step 302, after receiving the information of the secret opening mode, the server D generates an X key, stores the X key, the information of the secret opening mode, the ID of the terminal (terminal a) where the user a is located and the ID of the terminal (terminal C) where the user C is located in the server, and sends the X key to the terminal where the user a is located.
Step 303, the user a writes a file (a file to be sent) to be sent to the user C in the terminal a, adds the X key to the file to be sent in the terminal a to form a secret file a, and sends the secret file a to the user C through the server B.
After the user C receives the a secret document sent by the user a, the a secret document cannot be normally displayed on the C terminal because the X key is included in the a secret document.
In step 304, the user C needs to obtain the X key from the server D, and the user C sends the ID of the terminal C to the server D through the terminal C.
Step 305, the server sends an X key to the terminal C according to the received ID of the terminal C, and the terminal C decrypts the a secret file according to the X key to obtain a file to be sent.
It should be noted that the file processing method based on the instant chat tool provided by the embodiment of the present invention is further applicable to the following scenarios:
in a first scenario, if a specific scheme of high-level exchange financing of a company is adopted, a boss sends a commercial confidential document to a partner, the document can only be opened at a terminal where the partner is located, an IT management person cannot view the document from a background, and further, the confidential document cannot be decrypted and viewed due to the fact that the confidential document cannot be obtained when being forwarded again.
And if the confidential document needs to be displayed on the terminal of the friend, the terminal of the partner needs to send a secret key to the terminal of the friend, so that the terminal of the friend can display the confidential document.
Scene four: based on scenario one, when the boss searches for the file on a daily basis, the confidential file cannot be searched because the confidential file is encrypted, and therefore the risk that confidential information is leaked is reduced.
Finally, an embodiment of the present invention provides a file processing method based on an instant chat tool, including: the method comprises the following steps: sending secret opening mode information to a server, wherein the secret opening mode information carries the ID of a first terminal; and receiving a first secret key corresponding to the secret opening mode information fed back by the server, adding the first secret key into a first file to be transmitted to form a first secret file, transmitting the first secret file to a second terminal, so that the second terminal obtains the first secret key from the server after receiving the first secret file, and decrypting the first secret file according to the first secret key to obtain the first file to be transmitted. In the method, a message sender, that is, a first terminal, may generate a first key through an independent server, and load the first key in a first file to be sent for transmission, and accordingly, after receiving the first file to be sent loaded with the first key, a second terminal may need to decrypt the message to obtain the first file to be sent. The method solves the problem that the confidential information is leaked because an enterprise IT administrator can acquire any chat message in the system and all the chat messages are not encrypted; furthermore, the enterprise uses the method for specific workers through background management and control, when the workers use the chat tool to transmit files, the passwords are required to decrypt every time the transmitted files are checked, and the security of file transmission is greatly improved; moreover, the method only encrypts the transmitted file, and the corresponding data is not damaged, so that the existing way of avoiding data damage caused by secret leakage is avoided.
