Wherein, as an optional manner, the opening the security mode includes:

Prompting the terminal user to input a security mode open password;

After determining that the received security mode open password of the terminal user is consistent with the preset security mode open password, the security mode is enabled through verification.

Of course, the security mode can also be used to enable the password on the terminal, and the startup module is enabled to open. After the request of the underlying security module, the security mode is directly started, and the underlying security module is directly triggered to be triggered without the user inputting a password.

As shown in FIG. 8, the embodiment provides an information security delivery method, including the following steps:

S401: The terminal detects a trigger event that is triggered by an application control.

The method further includes: before the terminal detects a trigger event that the control of the application is triggered, the method further includes: the application receiving the information sent by the sending terminal, and prompting the user to trigger the control of the application;

The method further includes: when the terminal detects a trigger event that the control of the application is triggered, the method further includes:

Wherein, as an optional manner, the opening the security mode includes:

After determining that the received security mode open password of the terminal user is consistent with the preset security mode open password, the security mode is enabled through verification. The security mode is enabled, that is, the decryption may be performed in step S402.

S402: The terminal decrypts the information related to the trigger event.

After the terminal detects that the control of the application is triggered, the terminal decrypts the information related to the trigger event, including:

When the terminal detects that the user reads the information sent by the sending terminal of the application control, after identifying the encrypted identifier, the terminal prompts the terminal user to input a communication key, and receives the communication secret input by the terminal user. Key, or, after identifying the encrypted identifier, acquiring a preset communication key stored locally;

This embodiment will be described in further detail below in an application example.

In this application example, the application control includes a TextView (display) control and an EditView (edit) control, the encryption identifier is "palm whisper:", and the security mode has been turned on as an example, and FIG. 9 is an information security transfer method of the application example. The schematic diagram of the process, as shown in Figure 9, includes the following steps:

S301: User A and B are both parties of communication, and A and B tell the other party the communication key by using a method other than the channel in which the two parties are to perform secret communication;

S302: User A inputs the plaintext to terminal A.

S303: The bottom security module of the terminal intercepts the plaintext before the application, prompting the user to input a communication key, and the user A inputs a communication key agreed with the B;

S304: The bottom security module sends the encrypted ciphertext to the application.

The encrypted ciphertext includes: information encrypted in plaintext and an encrypted identifier, or information encrypted in plaintext, a version number of the encryption algorithm, and an encrypted identifier. At this point, the application obtains the ciphertext;

S305: The application stores the ciphertext in the local memory of the terminal.

The terminal local memory stores the communication information received and sent by the application, but is obtained by the application. Is cipher text, so the local memory is also stored in cipher text;

S306: The application network server, the application on the terminal A sends the ciphertext to the application network server, and the application network server forwards the ciphertext to the application on the terminal B;

Similarly, the application's web server stores the ciphertext in local storage on the network side. Obviously, the cryptographic text is also stored in the local storage on the network side.

S307: After receiving the ciphertext, the application on the terminal B stores the local memory on the terminal B and displays it to the user B, and displays a string of characters “palm cipher: FImG6DpTAF2acmMMF==” to the user B;

Among them, "palm whisper:" is an encrypted identifier, and the user can also know that the received information is ciphertext after seeing it. Obviously, the local memory stored on terminal B is also ciphertext.

S308: The underlying security module on the terminal B identifies the encrypted identifier at the bottom layer, and then prompts the user B to input the communication key.

S309: After user B inputs the correct communication key, the underlying security module decrypts the ciphertext and displays the plaintext sent by A to the user.

It can be seen from the above process that in the entire communication information transmission process, the information obtained and stored by the application, the information transmitted on the network, and the information obtained and stored by the application network server are all ciphertext. Even if the terminal is lost, or the intermediate network communication is intercepted, or the application's network server is compromised/abuse, the communication information will not be leaked.

Figure 10 is a schematic diagram of the principle of the underlying security module control application:

As shown in FIG. 10, an application is installed on the terminal, and an underlying security module is disposed at the bottom layer of the terminal, and the bottom security module is an integral part of the underlying framework layer;

The application's interface consists of a variety of system controls and custom controls inherited from system controls. Among them, 204 is a custom TextView control; 205 is a custom EditView control; you can see the inheritance relationship between the controls from Figure 10: 204 inherits from 206 (system TextView control); 205 inherits from 207 (system EditView control);

Presetting a control module in 206 and 207, the control module is configured to intercept a trigger event obtained by the control; communicate with the underlying security module, execute an instruction of the underlying security module; and input the control control And output.

Obviously, because 204 and 206, 205 and 207 are inheritance relationships, there are control modules inside these application custom controls; thus, the underlying security module can control the input and output of the application through the control module.

In addition, as needed, the control module can be preset in other controls provided by the system, and the other behaviors of the application can be controlled by the control module, so that the underlying security module controls the input and output of the application without any modification of the application. That is, in Figure 5, on terminal A, the underlying security module can obtain input prior to the application; on terminal B, the underlying security module can further process the output after the application gives the output. This actually takes advantage of the inheritance relationship of modern intelligent terminal window systems. It is difficult for an application to bypass the window system provided by the operating system and then write a separate window system. Therefore, the application must inherit the control module in the system control, and then be controlled by the underlying security module through the control module.

Figure 11 is a schematic diagram of the operation of turning on the security mode ("tight" mode) in the application example:

501 is a finger operation of the user, representing the user;

502 is a third party chat application;

503 is a "closed" switch. When a small black dot appears in the upper right corner of the figure, it indicates that it is in an open state; if there is no black small dot, it indicates that it is in a closed state;

401 is an interface that is popped up by the underlying security module to allow the user to input a password for turning on the "closed" mode;

402 is an input box for inputting a password for turning on the "closed" mode on 401;

403 is the interface when the input password is correct and the "closed" mode is opened. At this time, a black dot appears in the upper right corner of 503;

405 is when the input password is wrong, the "closed" mode is still in the closed state interface, at this time, the black dot in the upper right corner of 503 does not appear;

The operation process includes: when the 503 "closed" switch is in the off state, the user clicks 503 with the finger 501, and the bottom security module pops up 401. The user inputs a password for turning on the "closed" mode, and the user enters the password in 402, if the password is correct ( In accordance with the preset password, the "closed" mode is turned on, see 403; if the password is wrong, the "closed" mode is still off, see 405.

The above process verifies the identity of the user, indicating that the user has the right to use the terminal.

Figure 12 is an example of the operation of the underlying security module to convert user input into ciphertext and return to EditView:

501 is a finger operation of the user, representing the user;

502 is a third party chat application;

503 is a "closed" switch, which is in an open state;

504 is an interface that is displayed by the underlying security module to allow the user to input plaintext;

505 is an input method keyboard;

506 is the plain text input by the user;

507 is an interface that is displayed by the underlying security module to allow the user to input the communication password;

508 is a graphically entered communication password input by the user;

509 is the ciphertext returned to the EditView after being encrypted by the underlying security module;

The operation process includes: the user clicks the EditView control of the application 502 with the finger 501, because the 503 is in an open state (ie, the "closed" mode is opened), so the trigger event is intercepted and processed by the underlying security module, so that 504 is popped; the user is at 504. After entering the plaintext 506, click the communication password button to pop up the 507 interface, and let the user input the communication password 508 (in the figure, the communication password uses a graphic password, and actually can use multiple password forms), and then the user clicks OK. Button, return to the interface of 502; at this time, the ciphertext 509 encrypted by the underlying security module has been filled in the EditView, and the ciphertext is "palm cipher: FImG6DpTAF2acmMMF==", including: the version number of the encryption algorithm And the encryption identifier "palm:", the encryption identifier is pre-set; the user clicks the send button on the

interface

502, 502 sends the obtained ciphertext 509 to the network server, and stores the 509 into the terminal for local storage.

In the above process, the application cannot obtain the original text information of the user. Therefore, the application cannot steal the privacy of the user.

Figure 13 is a schematic diagram of the underlying security module decrypting the ciphertext using the key entered by the user and returning it to the TextView display:

601 is the application interface installed by the receiver;

602 is an interface that is displayed by the underlying security module to allow the user to input the communication password;

603 is a display plaintext interface that pops up when the key is correct;

604 is an error prompting interface popped up when the key is wrong;

The operation process includes: receiving the ciphertext 509 on the receiving terminal, and displaying the ciphertext "palm whisper: FImG6DpTAF2acmMMF==" on the TextView, wherein "palm cipher:" is an encrypted identifier, and the receiving party sees "palm whisper: ", immediately request to start the security mode, that is, open the "secret" mode decryption; wherein, the open way is as shown in Figure 7, the user clicks on the TextView, the underlying security module handles this touch event; the underlying security module is stored from the TextView display Obtaining the ciphertext 509, identifying the encrypted identifier, determining that decryption is required, and then popping 602 the key input box. If the recipient correctly inputs the key (pattern "Z"), the underlying security module decrypts according to the key. The decryption will succeed, and the underlying security module pops up 603 to display the plaintext to the recipient; if the recipient enters the wrong key, the decryption will fail, and the underlying security module pops up 604 to prompt the recipient to "key error."
