In the following, embodiments of the present invention are described in detail with reference to the accompanying drawings, and embodiments of the present invention provide a data protection method, where non-system data is protected by setting verification information for a memory of a non-system disk, and based on a hot-plug technology for the non-system disk, a hard disk is detached from a system side (i.e., the device cannot be found under the system), so as to perform data protection.
Specifically, fig. 1 is a schematic flow chart illustrating a data protection method according to an embodiment of the present invention, which may be applied to, for example, a mobile phone, a computer, and an electronic device having a plurality of storage devices. The electronic device may include at least a first memory and a second memory, wherein only the first memory is used for storing system data, and in the embodiment of the present invention, an authentication password or a hot key is not provided for the first memory, so that the electronic device can operate normally.

The controller in the electronic device may control power-on operations of the first memory and the second memory, and when the first memory and the second memory are powered on, it indicates that the first memory and the second memory are turned on, at this time, a user may query the first memory and the second memory in the electronic device and can read and write data in the memories, and when the first memory and the second memory are powered off, the first memory and the second memory are turned off. At this time, the user cannot inquire the corresponding memory, and thus cannot inquire the data in the memory. Therefore, in the embodiment of the present invention, the data protection in the memory may be performed by controlling the power-on of the memory by the controller.
Specifically, the user may set first preset verification information for the second memory to be protected in advance, where the first preset verification information is used to enable the controller to switch on the second memory, that is, to power on the second memory. The controller can judge whether first preset verification information for connecting the second memory is set after the controller enters an operating system or when the controller is started; if so, switching on the second memory when the first preset verification information is judged to be received; otherwise, disconnecting the second memory; and if the first preset verification information is not set, switching on the second memory.
That is to say, when a user needs to operate the second memory, the user can select to switch on the second memory by inputting the first preset authentication information, or the user can switch off the second memory to make the second memory invisible when the second memory needs to be hidden, and at this time, because the second memory is not accessed to the system, other users cannot access and cannot steal data, the security is higher.
Moreover, when the controller verifies that the first preset verification information for the second memory is not set, the second memory can be directly connected, at this time, the data in the second memory does not need to be kept secret, the data can be directly accessed into the system, and the user can directly perform corresponding operation.
The first preset verification information may be verification information such as a hot key, a password, a fingerprint, an iris, and an audio configured in advance, and may be stored in the controller, or in a memory accessible by other controllers, so that the controller may conveniently verify the input of the first preset verification information and perform corresponding operations.
In addition, as shown in fig. 2, a schematic flow chart of a data protection method in another embodiment of the present invention is shown, where, with respect to the embodiment of fig. 1, the data protection method in the embodiment of the present invention may further include:

receiving first configuration information which is input by a user and related to a second memory, wherein the first configuration information comprises a first state of the second memory when a starting program is executed;
and storing the first configuration information into the starting configuration information of the first memory.
Through the configuration process, the first configuration information of the second memory, which is configured in advance by the user, can be stored as the first state and is added into the starting configuration information of the first memory, so that corresponding configuration is carried out when the starting program is executed.
In addition, in the embodiment of the present invention as shown in fig. 3, the turning off the second memory in real time may specifically include:
judging whether second preset verification information for disconnecting the second memory is received or not;
if so, the second memory is disconnected, otherwise, the current state of the second memory is maintained.
The configuration of the first preset verification information is the same as that of the second preset verification information, and the user may set the second preset verification information for the second memory to be protected in advance, where the second preset verification information is used to enable the controller to turn off the second memory, that is, to turn off the power of the second memory. The controller can judge whether second preset verification information for disconnecting the second memory is received or not after the controller enters an operating system or when the controller is started; if yes, disconnecting the second memory; otherwise, the current state of the second memory is maintained.
That is to say, the user may select to disconnect the second storage by inputting the second preset authentication information when the user does not need to operate the second storage or wants to protect the data in the second storage, and at this time, because the second storage is not accessed to the system, other users cannot access and cannot steal the data, and the security is higher. And when the second memory is needed to be used, the second memory can be selected to be switched on, so that the use of a user is facilitated.
Further, in the embodiment of the present invention as shown in fig. 4, upon determining that the second preset authentication information is received,

That is, when the second preset authentication information is received, whether to save the access state of the second memory to the first state may be performed, so that the second memory may be directly turned on or off at the next boot. That is to say, the second preset verification information in the embodiment of the present invention may be used to disconnect the second memory, and may also be used to store the current state of the second memory as the first state, so as to facilitate configuration of the second memory when the computer is started next time.
Further, in the embodiment of the present invention, before the obtaining the selection information of whether to save the current access state of the second memory to the first state, it is further included to determine whether a shutdown instruction is currently received,
if so, executing selection information for acquiring whether the current access state of the second memory is stored as the first state;
otherwise, the second memory is disconnected when the second memory is judged not to be read or written.
That is to say, when receiving an instruction to disconnect the second preset verification information of the second memory, it may also be determined whether a shutdown instruction is received at this time, and if the shutdown instruction is received, a selection operation to save the first state is performed, otherwise, the second memory is directly disconnected.
Or, in another embodiment of the present invention, when a shutdown instruction is received, the selection information of whether to save the current access state of the second memory to the first state may also be directly executed;
if yes, the current state is saved as the first state, shutdown operation is executed, and otherwise, the shutdown operation is directly executed.
Therefore, the startup configuration information of the second memory can be conveniently acquired when the computer is started next time, and the operation is correspondingly executed.
In summary, in the embodiment of the present invention, the memory is electrically disconnected from the system in a manner of electrically disconnecting the hardware, so as to complete the thorough protection of the data, thereby not only completely protecting the data, but also reducing the service time of the hard disk; meanwhile, the security is higher, and a hacker cannot acquire the data through a network; in addition, the problem of data encryption and decryption does not exist, so that the time of the system for processing the data is reduced, and the user experience is improved.

The electronic device may comprise a first memory 1 and a second memory 2 and at least one second memory 2. Only the first memory 1 is used for storing system data, and in the embodiment of the present invention, an authentication password or a hot key is not provided for the first memory 1, so that the electronic device can operate normally. The second memory 2 can store data to be saved by the user or data with higher security, and can be provided with an authentication password or a hot key.
The controller 3 in the electronic device may control power-on operations of the first memory 1 and the second memory 2, and when the first memory 1 and the second memory 2 are powered on, it indicates that the first memory 1 and the second memory 2 are turned on, at this time, a user may query the first memory 1 and the second memory 2 in the electronic device and can read and write data in the memories, and when the first memory 1 and the second memory 2 are powered off, the first memory 1 and the second memory 2 are turned off. At this time, the user cannot inquire the corresponding memory, and thus cannot inquire the data in the memory. Therefore, in the embodiment of the present invention, the data protection in the memory can be performed by controlling the power-on of the memory by the controller 3.
Specifically, the user may set first preset verification information for the second memory 2 to be protected in advance, where the first preset verification information is used to enable the controller to switch on the second memory, that is, to power on the second memory. The controller can judge whether first preset verification information for connecting the second memory is set after the controller enters an operating system or when the controller is started; if so, switching on the second memory when the first preset verification information is judged to be received; otherwise, disconnecting the second memory; and if the first preset verification information is not set, switching on the second memory.
That is to say, when a user needs to operate the second memory 2, the user may select to turn on the second memory 2 by inputting the first preset authentication information, or may turn off the second memory 2 to make it invisible when the second memory 2 needs to be hidden, at this time, because the second memory 2 is not accessed to the system, other users cannot access and cannot steal data, and the security is higher.
Moreover, the controller 3 may determine whether or not first preset authentication information for turning on the second memory is set; if so, switching on the second memory when the first preset verification information is judged to be received; otherwise, disconnecting the second memory; and if the first preset verification information is not set, the second memory is connected for verification.
That is to say, when a user needs to operate the second memory 2, the user can select to turn on the second memory 2 by inputting the first preset authentication information, or the user can turn off the second memory to make it invisible when the second memory needs to be hidden, and at this time, because the second memory is not accessed to the system, other users cannot access and cannot steal data, the security is higher.
Moreover, when the controller 3 verifies that the first preset verification information for the second memory is not set, the second memory can be directly connected, at this time, it can be considered that the data in the second memory does not need to be kept secret, the data can be directly accessed into the system, and the user can directly perform corresponding operations.
The first preset verification information may be verification information such as a preset hot key, a password, a fingerprint, an iris, an audio and the like, and may be stored in the controller, or in a memory accessible by other controllers, so that the controller may conveniently verify the input of the first preset verification information and correspondingly perform the operation,
Further, when executing a boot program of the electronic device, the controller 3 may also read boot configuration information about the second memory 2 from the first memory 1; and selectively switches on or off the second memory 2 according to the first state in the power-on configuration information.
By the configuration, the second memory can be configured according to the pre-stored configuration information about the second memory when the startup operation is executed, that is, the startup configuration information about the second memory is read from the first memory when the startup program of the electronic device is executed. The boot configuration information may include a first state preconfigured for the second memory, where the first state may include turning on or off, and the second memory may be selectively turned on or off according to the first state in the boot configuration information when the boot program is executed.

the controller 3 judges whether second preset verification information for disconnecting the second memory is received or not; if so, the second memory is disconnected, otherwise, the current state of the second memory is maintained. The configuration of the first preset verification information is the same as that of the second preset verification information, and the user may set the second preset verification information for the second memory to be protected in advance, where the second preset verification information is used to enable the controller to turn off the second memory, that is, to turn off the power of the second memory. The controller can judge whether second preset verification information for disconnecting the second memory is received or not after the controller enters an operating system or when the controller is started; if yes, disconnecting the second memory; otherwise, the current state of the second memory is maintained.
That is to say, the user may select to disconnect the second storage by inputting the second preset authentication information when the user does not need to operate the second storage or wants to protect the data in the second storage, and at this time, because the second storage is not accessed to the system, other users cannot access and cannot steal the data, and the security is higher. And when the second memory is needed to be used, the second memory can be selected to be switched on, so that the use of a user is facilitated.
