Referring to fig. 1, fig. 1 is a schematic flow chart of a CMOS information removal method according to an embodiment of the present invention, where the embodiment of the present invention may include the following:

s101: face images of authorized users are stored in advance.

In this embodiment, the authorized user face images may include face images of a plurality of users, and in order to improve subsequent verification efficiency and verification accuracy, there may be a plurality of face images of each authorized user, each face image being a face image taken at a different angle.

S102: when the Clear CMOS operation issuing instruction is detected, the current face image of the user issuing the instruction is collected by loading the image sensor drive.

It can be understood that Clear CMOS operation is a user behavior, the system can monitor whether the user has the Clear CMOS behavior in real time by recognizing and clearing behavior identification information, when the user has the Clear CMOS operation behavior, the identity of the user issuing the Clear CMOS operation is checked first, and the identity of the user can be checked by collecting a face image of the current user and a face image of an authorized user stored in advance in S101.

In this application, the BIOS administrator password is pre-stored in the BIOS NVRAM password space, rather than being present in the CMOS chip. When the Clear CMOS operation is judged as an authorized user in S103, the Clear CMOS operation can be executed by the user, and then the BIOS administrator password is cleared, so that the BIOS administrator password is further protected from being deleted accidentally. After determining that Clear CMOS operation can be performed, Clear behavior identification information identifying whether Clear CMOS operation exists can be cleared, so that whether Clear CMOS operation behavior exists can be accurately determined in the following.

In the technical scheme provided by the embodiment of the invention, when the user executes Clear CMOS operation, a safety protection measure of face recognition is added, and the Clear CMOS operation is determined to be executed only when the user issuing a clearing command is an authorized user, so that a legal user can be allowed to execute the Clear CMOS operation, and the problem of security vulnerability existing when an unauthorized user or an intruder realizes the Clear CMOS operation function by removing a power supply battery or a jumper of a main board CMOS chip is effectively solved.

In addition, the image sensor becomes a standard configuration of an all-in-one machine or a notebook computer, so that extra operation burden can not be brought to a user, the method is practical, simple, convenient, safe and efficient, Clear CMOS operation can be safely executed based on the image sensor, and the requirements of the current market can be met from multiple angles of technology, cost, user experience and the like.

In the foregoing embodiment, how to execute step S101 is not limited, and the method for storing the face image of the authorized user in this embodiment may include the following steps:

and when an image acquisition instruction issued by a user image acquisition mode in a BIOS setting interface is received, loading an image sensor drive and prompting a user to acquire an image. And storing the collected face image of the user as an authorized user image in the authorized user image set in the image module flash memory. And according to the received exit instruction of the user image acquisition mode, exiting the BIOS setting interface and automatically executing the restart operation.

In this step, an option of the user image capture mode needs to be preset in a BIOS setting interface, i.e., BIOS Setup, and two sub-options of entering and exiting are set under the option. When a user authorized to execute Clear CMOS operation stores a face image of the user in the system, the user can firstly enter a setting interface of a BIOS (basic input/output system), a user image acquisition mode is clicked in the setting interface and an entry option is selected, after the system receives the entry of the user image acquisition mode, the image sensor can be automatically loaded to drive the image sensor to be in a working state, an image acquisition prompt is sent to the user, then the image acquisition operation is started to be executed, the face image of the current user is acquired, various face images can be acquired from multiple angles, and the acquired face image is stored in a flash memory of an image module. After the image acquisition is finished, the user clicks the exit option in the user image acquisition mode, and the system automatically exits the BIOS setting interface and restarts to ensure that the operation is effective.

In some embodiments of this embodiment, in order to further improve the security and reliability of the CMOS clear operation, after storing the acquired face image of the user as the authorized user image in the authorized user image set in the flash memory of the image module, the method may further include:

converting the collected user face images at different angles into feature vectors by adopting a feature face technology to generate a face feature vector set; extracting corresponding characteristic values from the face characteristic vector set, encrypting each characteristic value by adopting an encryption algorithm, and storing the encrypted face characteristic vector set in a BIOS NVRAM. The authorized face image and the feature vector after the encryption of the authorized face image are stored in a partitioned mode, so that a backup data is added, the safety of the stored data is improved, and the stored data is not easy to steal.

In this embodiment, in order to make the technical solution of this implementation more clear to those skilled in the art, as shown in fig. 2, this application further provides an illustrative example, which may include:

s11: and entering a BIOS Setup interface, selecting a user image acquisition mode, pressing a hot key F10, and selecting to save and restart.

S12: and loading the image sensor drive by the BIOS, lighting the image sensor, popping up a prompt on a BIOS Setup interface, and asking a user to collect the face. In the face acquisition process, the user can be subjected to image acquisition at different angles such as the front side and the side, and each user acquires 4 images which can be called as a registration photo.

S13: after the face collection is finished, the BIOS stores the registration photo in a FLASH of the image sensor module;

s14: the BIOS converts 4 human face images at different angles into a feature vector set by adopting a feature face technology according to the registration photo, extracts corresponding feature values, encrypts the feature values by adopting an SHA1 algorithm, stores the feature values in a BIOS NVRAM, stores the feature values in different areas with the registration photo, and performs data backup.

S15: selecting to quit the user image acquisition mode on a BIOS Setup interface, pressing a hot key F10, storing and restarting;

therefore, the embodiment of the invention further ensures the safety and reliability of Clear CMOS operation by encrypting and storing the face image of the authorized user in the partitioned mode.

In the above embodiment, how to execute step S102 is not limited, but in this embodiment, an implementation manner of detecting that Clear CMOS operation issues an instruction is provided, and in a system boot stage, the BIOS may determine whether a user has a behavior of Clear CMOS by detecting whether a CMOS chip has a Clear _ FLAG and a value of the FLAG, and may include the following steps:

in the initial stage of the power-on self-test process, whether CLEAR _ FLAG exists in the CMOS chip is judged, and the CLEAR _ FLAG is used as CLEAR behavior identification information of CLEAR CMOS operation. If CLEAR _ FLAG exists in the CMOS chip, reading the value of the CLEAR _ FLAG, and if the value of the CLEAR _ FLAG is the existence identification value such as 0, judging that CLEAR CMOS operation behavior exists in the user; if the value of CLEAR _ FLAG is the absence identification value such as 1, judging that CLEAR CMOS operation behaviors do not exist in the user; if CLEAR _ FLAG does not exist in the CMOS chip, the CLEAR _ FLAG is defined as CLEAR behavior identification information, and the CLEAR _ FLAG is initialized to an absence identification value such as 1 to identify that the CLEAR CMOS operation behavior does not exist for the user.

In order to make the technical solution of the present embodiment more clear to those skilled in the art, as shown in fig. 3, the present application also provides an illustrative example, which may include:

s21: the system is normally powered On, a Power-On key is pressed, the BIOS enters a POST (Power On Self Test) process, and Power-On Self Test is carried out.

S22: and reading the value of CLEAR _ FLAG in the CMOS chip by the BIOS at the initial stage of the POST process.

S23: if CLEAR _ FLAG is not present, a variable CLEAR _ FLAG is defined and initialized to 1, and the user is assumed to have no CLEAR CMOS behavior.

S24: if CLEAR _ FLAG is present, the value of FLAG is read. If the value is 0, the user is determined to have the action of Clear CMOS, otherwise, the user is determined not to have the action of Clear CMOS.

In the embodiment, the CLEAR _ FLAG is set to monitor the behavior of the CLEAR CMOS, so that the operation is more convenient and easier to realize.

It can be understood that if abnormal conditions such as blurring and incomplete face acquisition occur in the image acquisition process, which may cause that one-time verification cannot be truly successful, a phenomenon of misjudgment occurs, that is, an authorized user is originally verified as an unauthorized user once, in order to avoid that an authorized user cannot perform operations, multiple times of verification may be performed, in order to avoid time waste and better protect data, verification times are limited, that is, whether the number of times of verifying whether a current face image is an authorized user face image in a face image set of the authorized user exceeds a preset time threshold value or not is verified; if yes, the Clear CMOS operation execution is stopped, alarm prompt is carried out, and meanwhile shutdown operation is automatically executed. Based on the above, this embodiment further provides an implementation manner of the step S103, please refer to fig. 4, which includes the following steps:

s31: when the value of CLEAR _ FLAG is read to be 0, the BIOS determines that the CLEAR CMOS operation exists in the user, and triggers the BIOS face recognition program. At this time, the BIOS loads the image sensor driver, initializing the image sensor device.

S32: and popping up a prompt on the BIOS Setup interface, asking the user to recognize the face of the user, and simultaneously lighting the image sensor to enable the image sensor to be in a working state.

S33: after the user performs face recognition, the BIOS checks whether the user authorization is legitimate. If the authorization is illegal, the BIOS Setup interface pops up a prompt of 'identify error, please identify again'. And (4) checking for three times, after the checking fails, alternately alarming for 10S by the buzzer for one long and one short, and then executing shutdown operation by the BIOS, and skipping the following steps.

S34: if the authorization is legal, the BIOS Setup interface pops up a prompt to ask the user to confirm whether to execute Clear CMOS, and asks the user whether to execute the operation of Clear CMOS again, so as to avoid illegal operation caused by battery removal. If the user confirms that the selection is 'no', the Clear CMOS is not executed, Clear _ FLAG is reset to 1, and step S36 is executed to start the computer normally;

s35, if the user confirms that the selection is "YES," Clear CMOS is executed, the administrator password stored in BIOS NVRAM is cleared.

And S36, normally starting.

In the embodiment, by limiting the checking times, the authorized user can be ensured to execute the Clear CMOS efficiently, the occurrence probability of the misjudgment phenomenon is reduced, and the safety of the user stored data can be further ensured.

It should be noted that, in the present application, there is no strict sequential execution order among the steps, and as long as a logical order is met, the steps may be executed simultaneously or according to a certain preset order, and fig. 1 to fig. 4 are only schematic manners, and do not represent only such an execution order.
