An embodiment of the present disclosure provides a content writing method performed by an electronic device, including: detecting sound volume in the environment where the electronic equipment is located; under the condition that the sound volume is less than or equal to a preset volume threshold, writing content to be written into a storage device of the electronic equipment in a first mode; and under the condition that the sound volume is larger than the preset volume threshold, writing the content to be written into a storage device of the electronic equipment in a second mode.
The content writing method provided by the embodiment of the disclosure can write the content to be written into the electronic device by adopting the first writing method when the peripheral sound is detected to be small, for example, when the user does not speak or speaks the sound to be small, and write the content to be written into the electronic device by adopting the second writing method when the peripheral sound is detected to be large, for example, when the user speaks loudly or speaks by using a loudspeaker in a conference process. For example, in the case that the electronic device has both a solid-state disk and a mechanical hard disk, the first mode is to write the content to be written into the mechanical hard disk of the electronic device, and the second mode is to write the content to be written into the solid-state disk of the electronic device, so that the mechanical hard disk can be prevented from recording the sound information of the user and the sound information of the surrounding environment of the user; for another example, the first mode is to write the contents to be written into the mechanical hard disk in a normal order, and the second mode is to write the contents to be written into the mechanical hard disk in a disorder order or insert invalid contents into the contents during the writing process, so that when the sound information recorded by the mechanical hard disk is restored, the restored sound information is in a disorder or incomplete state, and thus, important sound information of a user can be prevented from being leaked.
Fig. 1 schematically shows an application scenario of a content writing method according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the content writing method according to the embodiment of the disclosure may be applied to a notebook computer 100, and a mechanical hard disk is disposed in the notebook computer 100, and the mechanical hard disk may be connected to the notebook computer 100 through an interface such as IDE, SCSI, USB, or the like. In the process of writing operation performed by the mechanical hard disk, when a user speaks voice or sound waves of ambient environment sound are transmitted to the mechanical hard disk, small changes of the mechanical hard disk during operation are caused, and the mechanical hard disk generates a recording effect. The magnetic head of the mechanical hard disk can generate certain position deviation when being interfered by sound waves, and the mechanical hard disk can record the position of the magnetic head, so that the effect of recording sound is achieved, and the recorded sound can be restored according to the position deviation of the magnetic head.
In order to prevent the sound of the user from being leaked, the mechanical hard disk should be prevented from acquiring the sound information of the user as much as possible or acquiring continuous and complete sound information of the user during the process of writing data into the notebook computer 100. According to the content writing method provided by the embodiment of the disclosure, the writing mode of data can be adjusted according to the size of the ambient sound, and the size of the sound can refer to the amplitude of the sound wave. When the peripheral sound is detected to be small, the sound wave is not large enough to enable the mechanical hard disk to record the sound, the content can be written in a common mode, and when the peripheral sound is detected to be large, in order to prevent the sound from being recorded, the content can be written in a mode of interfering the mechanical hard disk to steal sound information, for example, the content is written in a solid state disk, or the content is written in the mechanical hard disk in a disordered mode or an invalid sector mode, so that the mechanical hard disk cannot record the sound or cannot record the sound completely and continuously.
It is understood that the application scenario in fig. 1 is only an example, and the content writing method may be applied to other electronic devices that may have a mechanical hard disk, such as a host of a desktop computer, a kiosk, and the like, besides a notebook computer.
Fig. 2 schematically shows a flow chart of a content writing method performed by an electronic device according to an embodiment of the present disclosure.
As shown in fig. 2, the content writing method of an embodiment of the present disclosure may include operations S210 to S230.
In operation S210, detecting a sound volume in an environment where the electronic device is located;
in operation S220, when the sound volume is less than or equal to the preset volume threshold, writing the content to be written into the storage device of the electronic device in a first manner;
in operation S230, in the case that the sound volume is greater than the preset volume threshold, the content to be written is written into the storage device of the electronic device in the second manner.
According to an embodiment of the disclosure, the content writing method may be executed by an electronic device, for example, may be executed by a notebook computer, and is used to implement a privacy protection function of the electronic device, where for a user with a higher security requirement or in a scene with a higher security requirement, the user may open the privacy protection function, for example, the user may open the privacy protection function when in a meeting.
The storage device at least comprises a mechanical hard disk, and can also comprise other storage devices such as a solid state disk and the like.
Fig. 3A schematically illustrates a partial structural schematic diagram of a mechanical hard disk 300 according to an embodiment of the present disclosure.
As shown in fig. 3A, the mechanical hard disk 300 includes a magnetic head 310 and a disk 320, the number of the disk 320 may be multiple, each disk 320 includes two faces, and each disk face is correspondingly provided with a magnetic head.
FIG. 3B schematically shows a schematic view of a disk face according to an embodiment of the present disclosure.
As shown in fig. 3B, a plurality of tracks are disposed on the disk surface, the plurality of tracks are in a concentric circle structure, a plurality of straight lines extending along the radial direction divide each track into a plurality of arc segments, and one arc segment on each track is referred to as a sector, such as the sector 321, the sector 322, and the sector 323 in fig. 3B.
The magnetic head is placed on one side of the disk and keeps a certain distance with the disk, the disk rotates around the rotating shaft in the process of writing operation of the mechanical hard disk, the magnetic head moves relative to the disk, and the magnetic head magnetizes the magnetic tracks on the disk in the relative movement process. The magnetic head has different standard positions corresponding to different writing contents, for example, the standard position of the magnetic head is, for example, 0.05mm when writing "0", and the standard position of the magnetic head is, for example, 0.2mm when writing "1", and during reading, the position of the magnetic head can be read to distinguish whether "0" or "1" is recorded at the corresponding position of the disk. It should be noted that the specific numerical values given in the embodiments of the present disclosure are merely examples to enable those skilled in the art to understand the technical solutions of the present disclosure, and are not intended to limit the technical solutions of the present disclosure.
The mechanical hard disk has high requirement on the control precision of the position of the self read-write magnetic head, and the magnetic head can tolerate the error of the deviation from the center only on the nanometer level under the normal condition, so even the tiny air pressure oscillation caused by the sound wave can be sensed by the magnetic head. During the process of writing data in the mechanical hard disk, if a user speaks, sound waves can be transmitted to the mechanical hard disk, a magnetic head on the mechanical hard disk is vibrated to generate a certain position deviation, for example, when writing '1', the position of the magnetic head can deviate to 0.19mm, a disk can record the position error, and the larger the amplitude of the vibration is, the larger the position error of the magnetic head is. When data is read from the mechanical hard disk, the actual position of the magnetic head can be read, and the current sound information can be restored according to the deviation of the actual position and the standard position.
According to the embodiment of the disclosure, before data is written, the sound volume in the environment where the electronic device is located may be detected, and whether the sound volume is smaller than a preset volume threshold may be determined, where the preset volume threshold may be, for example, 70 db. The sound below the volume threshold is not enough to record the sound by the mechanical hard disk, so that the mechanical hard disk can normally write data, for example, the data is written in a system default mode without interference; sounds above the volume threshold can be sensed by the mechanical hard disk, and in order to prevent the sound information from being leaked, a certain protection measure needs to be taken, for example, writing operation is performed by adopting other storage devices, or writing operation is performed by making the mechanical hard disk out of order or inserting invalid sectors.
According to an embodiment of the present disclosure, the storage device includes a first storage device and a second storage device, where the first storage device is a mechanical hard disk, and the second storage device is another storage device different from the mechanical hard disk, and may be a solid state hard disk, for example.
Writing the content to be written into a storage device of the electronic device by adopting a first mode comprises the following steps: writing the content to be written into the mechanical hard disk; writing the content to be written into the storage device of the electronic device in a second mode comprises: and writing the content to be written into the second storage device.
Specifically, when the ambient sound is small, the data can be written by using a mechanical hard disk, and certainly, the data can also be written by using a solid state disk according to actual situations. When the ambient sound is large, the solid state disk SSD is used for data writing, specifically, the data can be written into a cache based on the SSD, and the sound can be prevented from being recorded by the mechanical hard disk.
If no other storage device is provided in the electronic device, or the mechanical hard disk is necessary to be used for writing in some specific cases, for example, when the cache is not allowed during power on or power off, or when the security requirement is high, such as processing an online banking service. In such a case where data writing must be performed using a mechanical hard disk, the mechanical hard disk may be caused to perform writing operation in the following manner.
According to an embodiment of the present disclosure, the content writing method of an embodiment of the present disclosure further includes: dividing the content to be written into a plurality of content parts according to the logic sequence of the content;
writing the content to be written into a storage device of the electronic device by adopting a first mode comprises the following steps: sequentially writing the plurality of content parts into the mechanical hard disk according to a first arrangement order, wherein the plurality of content parts are arranged according to the logic order of the content in the first arrangement order;
writing the content to be written into the storage device of the electronic device in a second mode comprises: the plurality of content portions are sequentially written into the mechanical hard disk in a second arrangement order, and at least two content portions are arranged in a disorder different from the logical order of the content in the second arrangement order.
Specifically, the content to be written is, for example, a piece of video, and the system allocates three sectors to the content to be written, for example, sectors 321, 322, and 323 that are distributed in series.
The logical order division of the content may refer to division in the front-back order of the content, for example, if the content to be written is an article, the article may be divided into three parts, i.e., front, middle and back, in the front-back order of the content.
The content to be written includes, for example, content a, content B, and content C, and is written in the sector 321, the sector 322, and the sector 323, respectively. The logical order of the content to be written is: content a, content B, content C.
In a first mode, writing is performed in consecutive sectors, the first arrangement order being: content a, content B, and content C are written in this order into sector 321, content B into sector 322, and content C into sector 323.
In a second mode, writing is performed in a non-sequential sector mode, the second arrangement order is any order different from the first arrangement order, and the second arrangement order may be, for example: content a, content C, and content B are written in this order into sector 321, content C into sector 323, and content B into sector 322. In this way, when the sound on the mechanical hard disk is restored, the sound is restored according to the logical sequence of the content, namely the sound on the sector 321, the sector 322 and the sector 323 is restored in sequence, and the sound recorded on the sector 323 is earlier than the sound recorded on the sector 322, so that the sound obtained by restoration is disordered and is discontinuous, and the information leakage is effectively avoided.
In addition to the out-of-order writing method, an invalid sector can be added during the writing process.
According to an embodiment of the present disclosure, writing content to be written into a storage device of an electronic device in a first manner includes: the plurality of content portions are written sequentially in a logical order into the mechanical hard disk.
For example, the logical order of the content to be written is: in the first mode, the content a, the content B, and the content C may be written in the sector 321, the content B in the sector 322, and the content C in the sector 323 in this order.
Writing the content to be written into the storage device of the electronic device in a second mode comprises: inserting invalid content between at least two adjacent content portions; and writing the plurality of content parts and the invalid content into the mechanical hard disk in sequence according to the inserted sequence.
For example, an invalid content E is inserted among the content a, the content B, and the content C, and for example, the order after inserting the invalid content is: when the sectors 324 and 325 are increased, the content a, the content E, the content B, the content E, and the content C may be written in the sector 321, the content E, the sector 322, the content B, the sector 324, and the sector 325 in this order in which the invalid content is inserted. The contents of the invalid sectors 322 and 324 can be deleted later, so that the sound obtained by the restoration is incomplete and discontinuous during the restoration, and the leakage of information can be effectively avoided.
In the case that the data size of the content to be written is not enough to fill up one sector, the content to be written may also be divided, and each part of the content may be allocated to a different sector for writing according to the second method described above.
According to an embodiment of the present disclosure, the content writing method of an embodiment of the present disclosure further includes: detecting the sound volume of the environment where the electronic equipment is located in the content writing process; and switching the writing mode of the content to be written under the condition that the sound volume changes between being larger than the volume threshold and being smaller than or equal to the volume threshold.
In the process of writing the content, the sound of the surrounding environment can be monitored in real time, and if the relation between the volume of the environment sound and the preset volume threshold value changes, the corresponding writing mode can be switched. For example, if it is detected that the volume is smaller than the preset volume threshold before the content is written, the content is written by using a mechanical keyboard, but it is monitored that the volume of the environmental sound exceeds the volume threshold in the content writing process, the writing operation may be switched from the mechanical hard disk to the solid state disk for execution, or the mechanical hard disk may be switched to a disorder mode or an invalid sector mode for execution, and after it is monitored that the volume is smaller than the preset volume threshold, the first mode may be switched back again.
