An embodiment of the present invention provides an eMMC control method, which includes, in combination with fig. 1, the following steps:
s101: and after the terminal is powered on, acquiring a power-on password of the user at the terminal.
In the embodiment of the application, the terminal can be any device with a storage function, such as a mobile phone, a television box, a vehicle event recorder and the like. The boot password may be a character password or biometric information of a person, such as facial identification information, fingerprint identification information, and the like. The character password and the biological identification information can be used as the starting password together. Taking a mobile phone as an example, when the boot password is a character password, after the boot screen of the terminal is displayed, the password input box is displayed on the display screen to prompt the user to input the password, when the display screen is a touch screen, the soft keyboard is displayed on the display screen for the user to input the password, and when the display screen does not have a touch function, the user can input the password through the physical keyboard.
S102: and writing data into the storage area when the user writing operation is acquired.
In the embodiment of the application, after the user inputs the power-on password, the user can write the data into the storage area no matter whether the power-on password is correct or not. The memory area includes a memory area in the central control chip (for example, a read-only memory area ROM in the central control chip) and an embedded multimedia card eMMC built in the terminal.
S103: when the starting password is the same as the preset verification password, inquiring whether to hide the data written into the storage area, if so, copying the encrypted data to the hidden area and deleting the data of the original storage area, and if not, not moving the data; and when the starting password is different from the preset verification password, the written data is not processed.
In the embodiment of the present application, the authentication password may be stored in a Flash memory (a non-volatile memory) of the terminal in advance. When a user inputs a power-on password, the eMMC controller calls a verification password in the Flash memory, the power-on password is compared with the verification password, when the power-on password is the same as a preset verification password, a display screen of the terminal displays a prompt for inquiring whether a data prompt box written in a storage area is hidden or not, and the user selects whether a prompt is sent to the prompt box according to the requirement of the user. If the user selects yes, the data is copied to the hidden area after being encrypted, the data in the original storage area is deleted, and if the user selects no, the data is not moved and is reserved in the storage area. In some embodiments, the operation of encrypting and copying data from the storage area to the hidden area and deleting data in the original storage area may not be performed when the user performs the writing operation, that is, the user may perform the above operation on data already stored in the storage area to hide data originally displayed by all people. When the boot password is different from the preset verification password, the written data is not processed, specifically, the terminal does not display a data prompt box for inquiring whether to hide the written storage area on the display screen, so that a user who inputs the boot password incorrectly writes the data into the storage area normally without knowing that the hidden area exists.
The eMMC control method further comprises the following steps:
s201: and when the user reads the operation, displaying the data in the storage area on the terminal.
S202: when the starting-up password is the same as the preset verification password, the hidden area is displayed, and the data in the hidden area can be read; when the boot password is different from the preset verification password, the hidden area is not displayed, and the data in the hidden area cannot be read.
In the embodiment of the application, when the boot password is the same as the preset verification password, the terminal displays the specific representation form of the hidden area on the display screen as an icon corresponding to the data in the hidden area, or displays the icon corresponding to the folder by taking the folder as the hidden area for storing the data. The icon of the data in the hidden area or the folder corresponding to the hidden area may be displayed in the same manner as the icon of the data in the storage area, and in order to distinguish the data in the hidden area from the data in the storage area, the icon may be displayed in a semi-transparent state, or a pattern of the icon may be marked, or a name of the folder corresponding to the hidden area or a name of the data in the hidden area may be marked by adding characters. When the boot password is different from the preset verification password, the icons of the folders corresponding to the hidden area and the icons corresponding to the data in the hidden area are not displayed, so that users who input the boot password incorrectly do not know the existence of the hidden area.
The eMMC control method further comprises the following steps:
s301: when a user reading operation is acquired, when the starting password is different from a preset verification password, authentication information input by the user is acquired, when the authentication information is the same as the preset verification information, the hidden area is displayed, and data in the hidden area can be read; and when the authentication information is different from the preset verification information, the hidden area is not displayed, and the data in the hidden area cannot be read.
In the embodiment of the application, an authentication frame for authenticating user information is displayed on a display screen of the terminal, the authentication information may be fixed information, such as fixed characters, the user may be asked questions in the form of questions in the authentication frame, an input frame is provided below the questions for the user to input answers, and when the answers input by the user are the same as the passwords stored in the terminal, the authentication information is the same as the preset authentication information. In some embodiments, the verification information may also be dynamic information, for example, the terminal obtains a dynamic password from the server through the communication module, the server sends the dynamic password to the communication device of the user, and an input box for inputting the dynamic password is displayed in a display screen of the terminal, when the dynamic password input by the user is the same as the dynamic password obtained by the terminal, that is, the authentication information is the same as the preset verification information. When the authentication information is the same as the preset verification information, the hidden area is displayed, the data in the hidden area can be read, but the data can only be read and can not be written in because the power-on password input by the user is different from the verification password.
The eMMC control method further comprises the following steps:
s401: and when the operation of resetting the verification password by the user is obtained, if the verification password is reset, deleting the data in the hidden area, and if the verification password is not reset, not operating the hidden area.
In the embodiment of the application, a reset icon of the reset password is displayed on a display screen of the terminal, when a user clicks the reset icon, a reset frame is displayed on the display screen, the original verification password and the reset verification password need to be input into the reset frame, and when the original verification password is input correctly, the input reset verification password is used as a new verification password. After the password reset is verified, all data in the hidden area are deleted, the workload of a user for deleting the data in the hidden area can be reduced, and the efficiency is improved.
The embodiment of the application also provides an eMMC control system, and the eMMC control system corresponds to the eMMC control methods in the embodiment one to one. As shown in fig. 2, the eMMC control system includes a power-on password obtaining module, a writing module, a password verifying module, a reading module, an information verifying module, and a resetting module.
