Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for managing clear CMOS according to an embodiment of the present invention, where the method includes:
step S11: collecting a fingerprint password of an administrator by using a fingerprint sensor, and judging whether an operating instruction of a clear CMOS is received or not; if yes, go to step S12;
step S12: judging whether the clear CMOS is legal or not through the fingerprint password of the administrator; if yes, go to step S13; if not, go to step S14;
step S13: executing clear CMOS;
step S14: the clear CMOS is disabled.
In the present embodiment, a clear CMOS management method is provided, by which safety and reliability in executing clear CMOS can be significantly improved.
In this embodiment, firstly, the fingerprint password of the administrator is collected by using the fingerprint sensor, specifically, in the actual operation process, when entering the BIOS setup interface, the relevant driver of the fingerprint sensor may be loaded by the BIOS, the fingerprint sensor is turned on, and after the fingerprint sensor is turned on, the administrator is requested to place a finger on the fingerprint sensor, and the fingerprint password of the administrator is collected. In the process, in order to ensure the accuracy and reliability of the acquisition result of the administrator fingerprint password, the acquisition process of the administrator fingerprint password can be completed in a multi-acquisition mode. When the fingerprint password of the administrator is acquired by the fingerprint sensor, the acquired fingerprint password of the administrator may be saved by pressing the hot key F10, and specifically, the acquired fingerprint password of the administrator may be stored in the bios nvram.
When the fingerprint password of the administrator is obtained, whether the mainboard receives the operating instruction of the clear CMOS is judged, and whether the clear CMOS is legal is verified through the fingerprint password of the administrator. That is, when the motherboard receives an operation instruction of the clear CMOS, the motherboard triggers a BIOS fingerprint verification program, initializes the fingerprint sensor, and asks the user to input a fingerprint password of the administrator on the fingerprint sensor, and if the fingerprint password input by the user on the fingerprint sensor is consistent with the fingerprint password of the administrator stored in the BIOS nvram, it indicates that the clear CMOS is a legal operation, and at this time, the clear CMOS can be executed; if the fingerprint password input by the user on the fingerprint sensor is not consistent with the fingerprint password of the administrator stored in the BIOSNVRAM, the clear CMOS is indicated to be illegal, and at the moment, the clear CMOS needs to be prohibited from being executed.
In addition, in order to ensure the accuracy and reliability of the verification result, whether the clear CMOS is legal or not can be determined by multiple times of verification, such as: the user can have the opportunity of inputting the fingerprint password on the fingerprint sensor for three times, if the verification for three times fails, the clear CMOS is indicated to be illegal, at the moment, the clear CMOS needs to be prohibited from being executed, and meanwhile, the buzzer can prompt the user that a lawless person executes the clear CMOS at present. Of course, in practical applications, the number of times of verification may also be adaptively adjusted, and details are not described herein.
Obviously, in the clear CMOS management method provided in this embodiment, because the clear CMOS can be executed only when the clear CMOS passes the fingerprint password verification of the administrator, compared with the prior art, the phenomenon that the clear CMOS can be directly executed only by turning off the battery for supplying power to the CMOS or finding the jumper on the motherboard is avoided, and thus the safety and reliability in executing the clear CMOS can be significantly improved. Moreover, the fingerprint sensor is already used as a standard accessory of the intelligent computer, so that the management method provided by the embodiment does not bring extra operation cost to the computer, thereby further improving the convenience of a user in managing the clear CMOS.
It can be seen that, in this embodiment, firstly, the fingerprint sensor is used to collect the fingerprint password of the administrator, and determine whether the operating instruction of the clear CMOS is received, if the operating instruction of the clear CMOS is received, the fingerprint password of the administrator is used to determine whether the clear CMOS is legal, if the clear CMOS is legal, the clear CMOS is executed, and if the clear CMOS is illegal, the clear CMOS is prohibited from being executed. Obviously, in the management method provided in this embodiment, the clear CMOS can be executed only when the clear CMOS passes the verification of the administrator fingerprint code, which avoids the phenomenon that the clear CMOS can be directly executed only by turning off the battery for supplying power to the CMOS or finding the jumper on the motherboard, compared with the prior art, thereby significantly improving the safety and reliability when the clear CMOS is executed.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the above steps: after the process of collecting the fingerprint password of the administrator by using the fingerprint sensor, the method further comprises the following steps:
and encrypting the fingerprint password of the administrator.
In this embodiment, after the fingerprint password of the administrator is acquired by the fingerprint sensor, the fingerprint password of the administrator is encrypted. Obviously, after the fingerprint password of the administrator is encrypted, the method can relatively reduce the probability that a lawbreaker steals the fingerprint password of the administrator to complete the verification of the clear COMS and execute the clear COMS, thereby further improving the safety and reliability of the password of the administrator in the using process.
In the actual operation process, the fingerprint password of the administrator may be encrypted by using a des (data Encryption standard) Encryption algorithm, an aes (advanced Encryption standard) Encryption algorithm, an RSA Encryption algorithm, or an MD5 algorithm, which is not described in detail herein.
As a preferred embodiment, the above steps: the process of encrypting the administrator's fingerprint password comprises the following steps:
the administrator's fingerprint password is encrypted using the SHA1 algorithm.
Specifically, in the present embodiment, the SHA1(Secure Hash Algorithm 1) Algorithm is used to encrypt the administrator's fingerprint password, because the SHA1 Algorithm can map data of any size to a smaller, fixed-length unique value, and therefore, after the administrator's fingerprint password is encrypted by using the SHA1 Algorithm, one cannot deduce any original information about the administrator's fingerprint password. Obviously, through the technical scheme provided by the embodiment, the overall reliability of people in the process of encrypting the fingerprint password of the administrator can be further ensured.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the above steps: before the process of collecting the fingerprint password of the administrator by using the fingerprint sensor, the method further comprises the following steps:
starting a BIOS, and judging whether a variable CMOS _ FLAG exists in the CMOS or not;
if the variable CMOS _ FLAG does not exist, defining the variable CMOS _ FLAG, and setting the value of the variable CMOS _ FLAG to be zero;
if the variable CMOS _ FLAG exists, judging whether a request for setting an administrator password by a user can be received;
if the request cannot be received, setting the value of a variable CMOS _ FLAG to be 1;
if the request is received, the target administrator password set by the user is obtained, and the value of the variable CMOS _ FLAG is set to be 2.
In this embodiment, in order to further ensure the security and reliability in the process of managing the clear CMOS, the administrator password may be set according to the user's requirement before the fingerprint sensor is used to collect the administrator fingerprint password.
Specifically, when the BIOS is started, it is first determined whether a variable CMOS _ FLAG exists in the CMOS, and if the variable CMOS _ FLAG does not exist in the CMOS, the value of the variable CMOS _ FLAG is set to zero, that is, the variable CMOS _ FLAG is used to identify an administrator password set by a user; if the CMOS has the variable CMOS _ FLAG, judging whether the mainboard can receive a request of setting an administrator password by a user, if the mainboard cannot receive the request of setting the administrator password by the user, indicating that the user does not need to set the administrator password, and in this case, setting the value of the variable CMOS _ FLAG to be 1, namely, marking that the user does not need to set the administrator password by using the value of the variable CMOS _ FLAG as 1; if the mainboard receives a request of setting the administrator password by the user, the target administrator password set by the user is obtained, and the value of the variable CMOS _ FLAG is set to be 2, namely, the administrator password set by the user is identified by using the value of the variable CMOS _ FLAG to be 2.
As a preferred embodiment, the above steps: the process of judging whether the operating instruction of the clear CMOS is received comprises the following steps:
judging whether the value of the variable CMOS _ FLAG is 0 or not;
if the value of the variable CMOS _ FLAG is 0, judging that an operating instruction of a clear CMOS is received;
if the value of the variable CMOS _ FLAG is not 0, it is determined that the operation command of clear CMOS has not been received.
It can be understood that when the value of the variable CMOS _ FLAG is 1 or 2, it indicates that the CMOS is in a normal operating state, and there is no operation behavior of clear CMOS; if the value of the variable CMOS _ FLAG is 0, it indicates that the CMOS _ FLAG has recovered to the default value, and there is an operation behavior of clear CMOS, so in this embodiment, it can be determined whether the motherboard receives an operation instruction of clear CMOS by the value of the variable CMOS _ FLAG.
As a preferred embodiment, the target administrator password is specifically a password consisting of upper case letters, lower case letters, numbers and characters.
Specifically, in the present embodiment, the target administrator password is set to a password composed of upper case letters, lower case letters, numbers, and characters. It can be thought that when the target administrator password is set to be in such a form, the cracking difficulty of the target administrator password can be relatively improved, so that the safety of the target administrator password in the use process can be improved.
As a preferred embodiment, the above steps: after the process of obtaining the target administrator password set by the user, the method further comprises the following steps:
judging whether the target administrator password meets a preset condition or not;
if not, prompting the user to reset the administrator password.
It can be understood that, in practical applications, in the process of setting the target administrator password by the user, a situation that the target administrator password does not meet the preset condition necessarily occurs, and in this situation, in order to ensure the reliability of the target administrator password in the subsequent use process, the user may be further caused to reset the administrator password meeting the preset condition by prompting the user to reset the administrator password. Obviously, the overall reliability of the target administrator password in the use process can be further improved by the arrangement mode.

the CMOS judging module 21 is used for collecting a fingerprint password of an administrator by using a fingerprint sensor and judging whether an operating instruction of a clear CMOS is received or not;
