In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The information transmission method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, fig. 1 is a schematic view of a scene in which a first electronic device and a second electronic device interact with each other, where the first electronic device and the second electronic device both have a social application program, and interact with each other through the social application program, and when the first electronic device sends a message to the second electronic device, the second electronic device can receive the message. It will be appreciated that the first electronic device and the second electronic device may be interchangeable, i.e. the first electronic device is able to receive a message when the second electronic device sends the message to the first electronic device. The first electronic device and the second electronic device may be intelligent terminals, such as a mobile phone, a tablet computer, a notebook computer, and the like.
As shown in fig. 2, which is an exemplary interaction flowchart between a first electronic device and a second electronic device, the first electronic device obtains first information to be sent, and generates second information associated with the first information when the first information includes private content, where the second information is information obtained by encrypting the first information. Wherein the second information comprises key information, the key information comprising first timestamp information of the first electronic device. Then, the first electronic device sends the second information to a second electronic device so that the second electronic device displays the second information in a target mode.
The first electronic equipment stores second information after sending the second information to the second electronic equipment, and displays the second information in a first display mode under the condition that the first time point is matched with the first timestamp information; or, when the first time point does not match the first timestamp information, displaying the second information in a second display manner.
When first electronic equipment sends the first information that carries the privacy content, through the mode of converting first information into second information earlier and then sending, guaranteed the privacy security of information transmission process to after sending, when local point in time and first time stamp information did not match, then show the second information with second display mode (for example ciphertext display mode), make the follow-up unable direct view first information of user (privacy content), guarantee the privacy security of first information.
The second electronic equipment receives second information sent by the first electronic equipment, wherein the second information comprises key information, and the key information comprises first timestamp information of the first electronic equipment. Displaying the second information in a first display mode under the condition that the second time point is matched with the first time stamp information; or, when the second time point does not match the first timestamp information, displaying the second information in a second display manner.
When the second electronic device receives the second information sent by the first electronic device in the privacy protection manner, the second information can be displayed in the first display manner, such as a plaintext display, only when the second time point matches the first time stamp information, so that the user can view the original first information (privacy content). However, if the second time point does not match the first timestamp information, the second electronic device displays the second information in a second display mode, such as ciphertext display, that is, the user cannot directly view the first information carrying the private content through the second electronic device, so that the privacy security of the first information is ensured.
As shown in fig. 3, a schematic flow chart of an information transmission method provided in the embodiment of the present application is shown, where the information transmission method is applied to a first electronic device, and the method includes:
s301: and acquiring first information to be sent.
In the first electronic device and the second electronic device, many types of social application programs are generally installed, and a user can send or receive information by using the social application programs.
Specifically, as shown in fig. 4, after the user logs in the social application on the first electronic device by using the account, when the user performs a chat session with the friend through the social application, the user may input chat content that the user wants to send in the dialog box, so that the first electronic device may obtain the chat content in the dialog box to obtain the first information to be sent. After the user clicks to send, the first message to be sent is converted into a sent message, and the sent message is displayed in a dialog box, for example, the chat message b and the chat message d in fig. 4 are messages that the user of the first electronic device has sent to the user of the second electronic device, and the chat message a and the chat message c are messages that the user of the second electronic device has sent to the user of the first electronic device.
As shown in fig. 5, "chat message e" in the input box of the first electronic device is the first information to be sent, which is acquired by the first electronic device.
S302: and generating second information associated with the first information under the condition that the first information comprises private content, wherein the second information is information obtained by encrypting the first information, and the second information comprises key information which comprises first timestamp information of the first electronic equipment.
It can be understood that the first information to be sent generally relates to some private information, such as an identity card number, a picture corresponding to the identity card, a bank card number, a picture corresponding to the bank card, a home address, a mobile phone number, and other information.
Specifically, the first electronic device may perform level division on the first information to be sent when the first information to be sent is obtained, for example, the first information to be sent is divided into a-G levels, where the a level is smaller than the B level, the B level is smaller than the C level, and so on. And, the first information to be transmitted with a level higher than the D level (E, F, G level) is set as private information, whereas the first information to be transmitted with a level lower than the D level (including the D level) is ordinary information. The common information can be directly sent and directly stored locally in the first electronic device, or the first electronic device sends the common information to the cloud server for storage after the common information is sent successfully. For example, when the first information to be sent is "do you know my identity card number", although several sensitive words such as the identity card number are involved, but the identity card number is not involved, the level of the first information to be sent can be determined as D, and when the first information to be sent is "do me identity card number", it is obvious that the level of the first information to be sent is E, that is, greater than D, and privacy content (specific identity card number) is included.
When the first electronic device identifies that the first information to be sent contains the private information, it indicates that the first information to be sent relates to the private information, and at this time, the private content needs to be sent in a protective manner.
In some optional embodiments, when there is private information in the first information to be sent, if the user wants to send the private information, the first electronic device may display a prompt box to prompt the user that the information includes the private information, and ask the user whether the user needs to select a protective sending method to send the first information.
Accordingly, after the first electronic device determines that the first information includes private content, the method may further include:
if receiving a sending operation aiming at the first information, displaying a prompt box;
generating second information associated with the first information in response to the determination operation for the prompt box.
Illustratively, as shown in fig. 5, a user inputs first information carrying privacy content in an input box, if the user clicks a send button of a social application on the first electronic device, the first electronic device displays a prompt box, as shown in fig. 6, prompts that the information relates to privacy, inquires whether to send the information in a protected sending manner, and displays a cancel and confirm button for the user to select, when the user selects and confirms, the first electronic device generates second information associated with the first information, and sends the first information in a protected sending manner (converted into the second information), and if the user selects the cancel button, the first electronic device directly sends the first information in a normal manner.
In the case where the first information is transmitted in the protected transmission method, it is necessary to generate a key, encrypt the first information with the key, and transmit the information as a privacy ciphertext.
In other embodiments, the first electronic device may also not display the prompt box, and when the first electronic device detects that the first information to be sent includes the private information, the first electronic device directly sends the private information in a protective manner.
When the user selects the protective mode for transmission, the first electronic equipment generates second information associated with the first information. In some embodiments, the key information includes first timestamp information of the first electronic device, and the first electronic device determines a specific target display mode according to a matching condition of the first timestamp information and a first time point at which the first electronic device displays the second information.
In some embodiments, the key information further includes device information of the first electronic device, and when the first electronic device successfully sends the second information, the first electronic device stores the second information locally in the first electronic device, or the first electronic device forwards the second information to the cloud server, so that the cloud server stores the second information. When a user logs in the social contact application at other electronic equipment by using the same account, the social contact application synchronizes second information through the cloud server, and the second information is directly displayed in a second display mode on the other electronic equipment due to the fact that the equipment information of the other electronic equipment is not matched with the equipment information of the first electronic equipment, for example, the first information is displayed in a ciphertext mode, so that the user is prevented from being capable of viewing the specific content of the first information at the other electronic equipment.
When generating the key information, the key information may be generated from the information (the first timestamp information, the device information of the first device, and the like) according to a random hash rule. The random hash rule is, for example, MD5 (Message-Digest Algorithm), belongs to a hash Algorithm, and can hash any section of plaintext data to obtain key information.
S303: and sending the second information to second electronic equipment so as to enable the second electronic equipment to display the second information in a target mode.
After obtaining the second information, the first electronic device may directly send the second information to the second electronic device.
The second information is sent after the first information is encrypted by the key, so that the safety of the first information carrying the private content in the transmission process can be effectively ensured.
In some optional embodiments, after the first electronic device sends the second information to the second electronic device, the local of the first electronic device will usually generate a chat record related to the second information, the user will view the chat record because of his own needs, and in order to ensure the privacy and safety of the chat record, after the first electronic device sends the second information to the second electronic device, the method may further include:
storing the second information;
displaying the second information in a first display mode under the condition that a first time point is matched with the first timestamp information;
or, when the first time point does not match the first timestamp information, displaying the second information in a second display manner.
It can be understood that, since the key information includes the first timestamp information of the first electronic device, when the user subsequently views the transmitted first information locally on the first electronic device, if the viewed first time point does not match the first timestamp information, only the second information displayed in the second display manner can be viewed, and if the viewed first time point matches the first timestamp information, the first information displayed in the first display manner can be viewed.
In some specific embodiments, after the first electronic device sends the second information, the first electronic device stores the sent information locally, that is, stores the sent second information, or the first electronic device uploads the sent second information to the cloud server, and the cloud server stores the second information.
In order to ensure the privacy and safety of the first information, the second information is displayed in a first display mode under the condition that the first time point is matched with the first timestamp information. Wherein, the first time point may be a current time when the user views the transmitted second information using the first electronic device. As can be appreciated, displaying the second information in the first display manner may be: the second information is decrypted to display the second information in plain text (i.e., to display the first information). That is, when the current time when the subsequent user views the sent second information at the first electronic device side matches the first timestamp information, the first electronic device decrypts the second information and displays the second information in a plaintext (i.e., displays the first information), and at this time, the user can directly view the content of the first information.
In addition, the second information is displayed in a second display manner when the first time point does not match the first timestamp information. As can be appreciated, displaying the second information in the second display manner may be: the information is still displayed in the form of ciphertext (i.e., display of the second information). That is, when the current time of the transmitted second information viewed by the subsequent user at the first electronic device side does not match the first timestamp information, the first electronic device directly displays the second information in a ciphertext manner, and at this time, the user cannot directly view the specific content of the first information.
Optionally, the first timestamp information includes sending time point information and preset duration information.
And matching the first time point with the first timestamp information under the condition that the first time point is within a preset time interval.
Or, in a case that the first time point is not within the preset time interval, the first time point is not matched with the first timestamp information.
The first time point is the current time point of the first electronic device when the second information is displayed, and the preset interval is determined by the sending time point information and the preset duration information.
For example, when the transmission time point information is 8 00, the preset duration information is 3 minutes, and when the transmission time point information is the start time of the preset time interval, and the preset duration information is 3 minutes, the preset time interval is 8 00-01-03, when the first time point (8. For example, the first information is "my identity card number is 123456", the encrypted second information is "my identity card number is", and the second information is displayed in a first display mode as follows: "my identification number is 123456" is displayed. When the first time point (8: "my identification number is shown.
It should be noted that the situation that the first electronic device displays the second information again after sending the second information may be that the user triggers the first electronic device to display when clicking to view the sent message, or that the user re-clicks to enter the dialog box after exiting from the current dialog box, and the second information is exactly in the interface displayed by the dialog box. Since there are various ways to trigger the first electronic device to display the second information, they are not listed here.
In addition, the preset duration information can be set according to the requirements of the user. Alternatively, the preset time period may be calculated only after detecting that the user exits from the dialog interface, for example, after the user sends the second information, the user exits from the dialog interface after displaying half an hour, and the end time of the preset time interval is half an hour plus the preset time period information, that is, the user may see the second information displayed in the first display mode (i.e., directly display the first information) without exiting from the dialog interface.
In some optional embodiments, as shown in fig. 7, in order to facilitate the user to know that the first information is sent by a protected sending method, after the first electronic device sends the second information to the second electronic device, a prompt "description" may be displayed on the dialog box: through the protective sending mode, plaintext display at any end cannot be performed subsequently, so that a user is prompted that the second information displayed in the plaintext cannot be checked (namely, the first information is displayed) when the second information is outside a preset time interval.
The first electronic equipment sends the second information to the second electronic equipment in a protective mode, so that the safety of the first information in the transmission process is guaranteed, the first information can be further protected in privacy through the matching degree of the first timestamp information of the first electronic equipment in the key information and the first time point of the first electronic equipment, the fact that the first electronic equipment cannot display the second information in the clear text in the follow-up process is achieved, and therefore the safety of the local information of the first electronic equipment is guaranteed.
In the embodiment of the application, when first information to be sent acquired by first electronic equipment includes private content, second information associated with the first information is generated, wherein the second information is information obtained by encrypting the first information. And then, the first electronic equipment sends the second information to the second electronic equipment so as to protect the privacy content when the information carrying the privacy content is transmitted.
Fig. 8 is a schematic flowchart of an information transmission method provided in an embodiment of the present application, where the information transmission method is applied to a second electronic device, and the method includes:
s801: second information sent by a first electronic device is received, wherein the second information comprises key information, and the key information comprises first timestamp information of the first electronic device.
S802: displaying the second information in a first display mode under the condition that a second time point is matched with the first timestamp information;
s803: or, when the second time point does not match the first timestamp information, displaying the second information in a second display manner.
After first electronic equipment sends second information to second electronic equipment, the second electronic equipment receives the second information sent by the first electronic equipment, wherein the second information comprises key information, and the key information comprises first timestamp information of the first electronic equipment. And then, the second electronic equipment determines a specific target mode according to the matching condition of the second time point and the first time stamp information.
It is understood that the second time point is a current time point when the second electronic device displays the second information. And the second electronic equipment displays the second information in different target modes according to the matching condition of the second time point and the first time stamp information. That is, the second electronic device displays the second information in a different manner in the case where the second time point does not match the first time stamp information and in the case where the second time point matches the first time stamp information.
Specifically, the target mode includes a first display mode and a second display mode, and for example, the first display mode may be a plaintext display mode, that is, the second electronic device converts the second information into the first information to be directly displayed, so that the user can view the content of the first information conveniently; the second display mode can be a cipher text display mode, so that a user cannot directly view the specific content of the first information.
And the first information is the information obtained after the second information is decrypted.
Optionally, the first timestamp information includes sending time point information and preset duration information.
And under the condition that the second time point is within a preset time interval, matching the second time point with the first timestamp information.
And under the condition that the second time point is not in the preset time interval, the second time point is not matched with the first timestamp information.
The second time point is the current time point of the second electronic device when the second information is displayed, and the preset time interval is determined by the sending time point information and the preset duration information.
For example, after the second electronic device receives the second information, a time point triggered to display the second information is a second time point, the first timestamp information of the first electronic device is 8 00. At this time, if a second time point (8: "my identification number is 123456" is displayed.
When a second time point (8: "my identification number is shown.
