An embodiment of the present disclosure provides a user identification method performed by an electronic device, including: obtaining a keyboard operation mode of a first user; receiving first content information input by a user to be identified through a keyboard within a first time period; controlling a mechanical hard disk on the electronic equipment to execute writing operation in the first time period; acquiring first fluctuation information recorded in the process that the mechanical hard disk executes write operation in the first time period; and identifying whether the user to be identified is the first user based on the first content information and the first fluctuation information and the keyboard operation mode of the first user.
The user identification method provided by the embodiment of the disclosure can record the habit of using the keyboard by using the mechanical hard disk, the magnetic head of the mechanical hard disk is interfered by sound waves and mechanical vibration waves generated by knocking the keyboard, certain position deviation can occur, the position deviation condition of the magnetic head is different when the force and the speed of knocking the keyboard are different, and the force and the speed of knocking the keyboard by each user have own unique habit, so that the habit of using the keyboard by using the mechanical hard disk can be recorded, and whether the user currently operating is the correct user or not can be identified according to the recorded keyboard use habit. And the mechanical keyboard is extremely accurate in controlling the position of the magnetic head, so that the user identification method provided by the embodiment of the disclosure can accurately identify the user by using the mechanical hard disk.
Fig. 1 schematically illustrates an application scenario of a method of identifying a user according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a method for identifying a user to 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, and does not mean that the embodiments of the present disclosure may not be used in other apparatuses, environments or scenarios.
As shown in fig. 1, the user identification 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, if a user taps the keyboard, no matter sound generated by tapping the keyboard or vibration of the keys is transmitted to the mechanical hard disk through the mechanical connection structure, small change of the mechanical hard disk during operation can be caused, and the mechanical hard disk can generate a recording effect. The magnetic head of the mechanical hard disk can generate a certain position deviation when being interfered by sound waves and mechanical vibration waves generated by knocking a keyboard, so that the mechanical hard disk can record the keyboard operation habit of a first user in the process of executing writing operation, and particularly can reflect the difference of input habits of different users when the users input more familiar contents, for example, when a shortcut key is knocked or a password is input, the input speed, the knocking strength and the discontinuous habits of different users are different, for example, the speed habit of knocking a specific key combination and the specific mode when the users delete the specific key combination are different. In this way, after a period of recording and processing, the mechanical hard disk can obtain the keyboard operation mode of the first user according to the content input by the first user via the keyboard and the position deviation of the magnetic head in the period of time.
Thereafter, whether the current user is the first user himself or herself may be recognized according to the keyboard operation mode of the first user. In the identification process, the content input by the current user through the keyboard and the magnetic head position deviation recorded by the mechanical hard disk can be recorded, the input content and the magnetic head position deviation are matched with the keyboard operation mode of the user, if the matching is successful, the current user is considered as the first user, if the matching is wrong, the current user is considered not to be the first user, and any request operation of the current user can not be executed.
The user identification method provided by the embodiment of the disclosure can be based on the sensing technology of sound and mechanical vibration of a mechanical hard disk, and the detection of physical input of a specific operator is realized by combining an operating system, so that whether the user operates the user is judged, and finally the safety level of computer operation is improved.
It is understood that the application scenario in fig. 1 is only an example, and the user identification method may be applied to other electronic devices having or connected to a keyboard and a mechanical hard disk, such as a host computer of a desktop computer, a kiosk, and the like, besides a notebook computer.
Fig. 2 schematically shows a flow chart of a user identification method according to an embodiment of the present disclosure.
As shown in fig. 2, the user identification method according to the embodiment of the present disclosure includes operations S210 to S250:
in operation S210, obtaining a keyboard operation mode of a first user;
receiving first content information input by a user to be identified via a keyboard within a first time period in operation S220;

in operation S250, whether a user to be identified is a first user is identified based on the first content information and the first fluctuation information, and a keyboard operation pattern of the first user.
According to the embodiment of the disclosure, the user identification method can be executed by the electronic device and is used for realizing the user identification function of the electronic device, and the user can start the user identification function for the user with higher safety requirement or under the scene with higher safety requirement.
The electronic device may be, for example, a notebook computer, and the first user may refer to a common user of the notebook computer, and may be, for example, an owner of the notebook computer. The keyboard can be a keyboard integrated on the notebook computer or an independent keyboard connected with the notebook computer, and the notebook computer can obtain the input content of the keyboard. The mechanical hard disk may be integrated into a notebook computer, and the user identification method according to the embodiment of the present disclosure may be executed by a processor of the notebook computer, for example, and the processor is connected to the mechanical hard disk and can control the mechanical hard disk.
According to an embodiment of the present disclosure, obtaining the keyboard operation mode of the first user may be obtaining a pre-stored keyboard operation mode in a storage device of the electronic device.
FIG. 3 schematically shows a flow chart for obtaining a keyboard operational mode according to an embodiment of the present disclosure.
As shown in fig. 3, according to the embodiment of the present disclosure, the keyboard operation mode of the first user may be obtained in advance through operations S310 to S340:
receiving second content information input by the first user through the keypad within a second time period in operation S310, wherein the second time period is earlier than the first time period;
in operation S320, controlling a mechanical hard disk on the electronic device to perform a write operation within a second time period;
in operation S330, second fluctuation information recorded during the writing operation performed by the mechanical hard disk in the second time period is obtained;
in operation S340, a keyboard operation mode of the first user is derived based on the second content information and the second fluctuation information.
According to the embodiment of the present disclosure, the operation of obtaining the keyboard operation mode of the first user may be performed in response to a request of the user, for example, when the first user starts the user identification function for the first time, operations S310 to S340 are performed to obtain the keyboard operation mode of the first user as a basis for identifying the user later.
The second time period is earlier than the first time period, and the duration of the second time period may be, for example, one hour, half an hour, or the like. In the second time period, the user may input any content, or the electronic device may display preset input content for the user by using a display device connected to the electronic device, so that the user inputs the preset input content displayed by the display device through a keyboard. Meanwhile, in the second time period, the mechanical hard disk on the electronic device is controlled to perform writing operation in the second time period, and the way of recording sound and vibration by the mechanical hard disk is irrelevant to the writing content of the mechanical hard disk, so the writing content can be any preset content.
The mechanical hard disk comprises a magnetic head and a disk, wherein a plurality of magnetic tracks are arranged on the disk, each magnetic track is divided into a plurality of circular arcs, each circular arc is called as a sector, the magnetic head is placed on one side of the disk and keeps a certain distance with the disk, the disk rotates around a rotating shaft in the process of performing writing operation on 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 motion process. The magnetic head has different standard positions corresponding to different writing contents, for example, the standard position of the magnetic head is 0.05mm when writing "0", the standard position of the magnetic head is 0.2mm when writing "1", and the position of the magnetic head can be read during reading to distinguish whether "0" or "1" is recorded on 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. If a user taps the keyboard during writing, sound waves and mechanical vibration waves generated by tapping the keyboard can be transmitted to the mechanical hard disk, and the 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, the 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, but as long as the error between the actual position and the standard position is within an allowable range, an accurate numerical value can be read when content is read.
According to the embodiment of the disclosure, controlling the mechanical hard disk on the electronic device to perform the writing operation in the second time period comprises: and controlling the mechanical hard disk to write the preset content into a partial sector of the mechanical hard disk in a second time period, and recording second position information of a magnetic head of the mechanical hard disk in the partial sector after the writing operation is completed. And the second position information is the real position information of the magnetic head in the process of executing the writing operation in the second time period by the mechanical hard disk.
According to an embodiment of the present disclosure, controlling a mechanical hard disk on an electronic device to perform a write operation in a second time period may refer to: and controlling the mechanical hard disk to continuously perform the writing operation in the second time period, namely continuously performing the writing operation from the beginning to the end of the second time period, so that all sound and vibration in the second time period can be recorded. Alternatively, it may also mean: and controlling the mechanical hard disk to stop the writing operation when the suspension duration of the keyboard input operation is detected to exceed the preset duration in the second time period, and controlling the mechanical hard disk to execute the writing operation when the keyboard input operation is detected again. For example, in the second time period, it is detected that the user has not performed the keyboard input for more than 10 minutes, the writing operation of the mechanical hard disk is stopped to reduce the writing of the useless information, and when it is detected again that the user has performed the keyboard input operation, the mechanical hard disk is controlled to continue the writing operation. It should be noted that the operating system may occasionally start the disk caching operation, and needs to turn off the function while the mechanical hard disk starts writing, and if the electronic device is provided with a solid state disk, the operation of writing the disk needs to be switched from the solid state disk to the mechanical hard disk.
According to the embodiment of the disclosure, obtaining the second fluctuation information recorded during the writing operation performed by the mechanical hard disk in the second time period may refer to: and reading the second position information of the magnetic head in the partial sector, obtaining the position error information of the magnetic head according to the second position information of the magnetic head and the standard position information, and taking the position error information of the magnetic head as second fluctuation information.
According to an embodiment of the present disclosure, deriving the keyboard operation mode of the first user based on the second content information and the second fluctuation information includes: obtaining a plurality of second specific content information in the second content information; obtaining second specific fluctuation information that matches each of the second specific content information from the second fluctuation information; the keyboard operation mode includes a mapping relationship between the plurality of second specific content information and the plurality of second specific fluctuation information.
Specifically, the second specific content information may be, for example, a specific shortcut key, a specific key, a password, a specific word, a name, a mobile phone number, and the like, and the specific information is extracted from the second content information, and then a plurality of second specific fluctuation information corresponding to the second specific content information are extracted from the second fluctuation information, that is, position error information of a magnetic head of the mechanical hard disk when the user inputs the second specific content information is extracted, and a corresponding relationship between the plurality of second specific content information and the plurality of second specific fluctuation information is taken as a keyboard operation mode of the first user. In the case where a certain second specific content information appears a plurality of times, an average value or a maximum value of a plurality of second specific fluctuation information corresponding to the second specific content information may be taken, or a deviation range may be set, for example, in the second time period, when the space key is tapped a plurality of times by the user, the positional deviation of the magnetic head is 0.007mm, 0.1mm, and 0.008mm, respectively, and the maximum positional deviation of the magnetic head of 0.01mm is taken to correspond to the space key. In the case where the second specific content has a long content length, the second specific fluctuation information corresponding thereto may be a set of head position deviation values recorded on the mechanical hard disk during the input of the second specific content, and for example, if the second specific content is the password "111111", and the head position deviation values corresponding to the password are 0.01mm, 0.009mm, …, 0.007mm, and 0.006mm in this order, the password "111111" may be associated with the set of position deviation values.
After obtaining the keyboard operation mode of the first user, the user identification may be performed periodically or aperiodically according to the keyboard operation mode of the first user, for example, the user identification operation may be set to be performed every 1 hour during the operation of the electronic device, or the user identification operation may be performed once when a specific request of the user is received, for example, a request for opening a login interface of a certain website, or a request for opening a certain folder in which a password is set.
In the process of identifying the user by using the keyboard operation mode of the first user, receiving first content information input by the user to be identified via the keyboard within a first time period, where the first time period may be a fixed time period, for example, 10 minutes, half an hour, and the like, or the time period of the first time period may also be determined according to the input content, and for example, the first time period may be terminated when it is detected that the user to be identified inputs a certain specific content, specifically, for example, when it is detected that the user to be identified inputs a password.
According to the embodiment of the disclosure, first content information input by a user to be identified via a keyboard in a first time period is received, wherein the first content information may refer to all contents input by the user to be identified via the keyboard in the first time period.
According to the embodiment of the disclosure, the control of the mechanical hard disk on the electronic device to perform the writing operation within the first time period may refer to the control of the mechanical hard disk to continuously perform the writing operation within the first time period, that is, continuously perform the writing operation from the beginning to the end of the first time period, and be capable of recording all sound and vibration within the first time period. Or, in the first time period, when it is detected that the suspension duration of the keyboard input operation exceeds the preset duration, controlling the mechanical hard disk to stop the writing operation, and when the keyboard input operation is detected again, controlling the mechanical hard disk to execute the writing operation. For example, in the first time period, it is detected that the user to be identified has not performed the keyboard input for more than 5 minutes, the writing operation of the mechanical hard disk is stopped to reduce the writing of the useless information, and when it is detected again that the user to be identified performs the keyboard input operation, the mechanical hard disk is controlled to continue to perform the writing operation.

The first position information is the real position information of the magnetic head in the process of executing the writing operation in the first time period by the mechanical hard disk.
Obtaining the first fluctuation information recorded during the writing operation performed by the mechanical hard disk in the first time period may refer to: and reading first position information of the magnetic head in the partial sector, obtaining position error information of the magnetic head according to the first position information of the magnetic head and the standard position information, and taking the position error information of the magnetic head as first fluctuation information.

According to an embodiment of the present disclosure, identifying whether the user to be identified is the first user based on the first content information and the first fluctuation information, and the keyboard operation mode of the first user may refer to: obtaining a plurality of first specific content information in first content information in a first time period; obtaining first specific fluctuation information matching each of the first specific content information from the fluctuation information in the first period of time; whether the user to be identified is the first user is identified based on the first specific content information, the first specific fluctuation information, the second specific content information, and the second specific fluctuation information.
