[0053] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0054] In the description of the invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] It should be noted that the Basic Input Output System (BIOS) can usually set a password through a software-installed executable program (Setup).

[0056] When the BIOS sets a password through Setup, the historical password can be stored in the ROM. The historical password stored in the ROM is difficult to modify by external means and has relatively high external security.

[0057] However, the method of using the ROM to store the historical password has vulnerabilities. That is, in the case where the information corresponding to the ROM address storing the historical password does not match, the storage of the historical password will fail, and in the case where the ROM information is tampered with, the historical password stored in the ROM will become invalid, resulting in the possibility that the currently set password may be the same as the historical password, posing a relatively large security risk.

[0058] In view of this, the present invention provides a password setting method. Based on the password setting method provided by the present invention, in the case of setting a password for the non-first time, the identification information of the historical password can be obtained from the ROM. The identification information of any historical password includes characters used to describe the setting order of the above-mentioned any historical password among all historical passwords. Furthermore, the security of the ROM can be verified based on the historical password and the identification information of the historical password, and when the ROM passes the security verification, the password can be set again. It can effectively avoid the invalidation of the historical password stored in the ROM with only a small amount of computing resources consumed, improve the security of the ROM for storing the historical password, perform password setting more securely, and better ensure the security of the computer.

[0059] Figure 1 is one of the flow schematic diagrams of the password setting method provided by the present invention. The following combines Figure 1 to describe the password setting method of the present invention. As Figure 1 shown, the method includes: Step 101, when the current password to be set by the password setting object this time is obtained, search for the historical password of the password setting object in the read-only memory ROM.

[0060] It should be noted that the execution subject of the embodiments of the present invention is a password setting device.

[0061] It should be noted that the password setting object of the password setting method provided by the present invention can be a computer, or a certain software, a certain application program, or a certain display interface, etc. The password setting object of the password setting method in the embodiments of the present invention is not limited.

[0062] Specifically, in the case of receiving a request message indicating a request to set a password for the password setting object, the current password to be set by the password setting object this time can be obtained in various ways. For example: the current password to be set this time input by the user can be received; or, the current password to be set this time sent by other electronic devices can also be received. The specific way to obtain the current password to be set by the password setting object this time in the embodiments of the present invention is not limited.

[0063] After obtaining the current password to be set by the password setting object this time, the historical password corresponding to the password setting object can also be searched in the ROM.

[0064] It should be noted that the historical password in the embodiments of the present invention refers to all the passwords set for the password setting object before setting the password for the password setting object this time.

[0065] Step 102: When the historical password is found in the ROM, obtain the historical password and the identification information of the historical password. The identification information of any historical password includes characters used to describe the setting order of any historical password among all historical passwords.

[0066] Specifically, if the historical password corresponding to the password setting object is found in the ROM, it can be determined that setting the password this time is not the first time to set a password for the password setting object.

[0067] It can be understood that the number of historical passwords in the embodiments of the present invention can be one or more.

[0068] When it is determined that setting the password this time is not the first time to set a password for the password setting object, the historical password and the identification information of the historical password of the password setting object can be obtained from the ROM. Among them, the identification information of any historical password includes characters used to describe the setting order of the any historical password among all historical passwords.

[0069] The identification information of any historical password can be generated based on the setting order of the any historical password among all historical passwords and a preset generation rule after setting the any historical password for the password setting object.

[0070] Among them, the setting order of any of the above historical passwords in all historical passwords can represent the cumulative number of times the password has been set for the above password setting object after setting any of the above historical passwords. For example, when the character used to describe the setting order of a certain historical password is "1", it can be represented that after setting the above historical password for the above password setting object, the cumulative number of times the above password setting object has set a password is once, and setting the above historical password for the above password setting object is the first time to set a password for the above password setting object; when the character used to describe the setting order of a certain historical password is "3", it can be represented that after setting the above historical password for the above password setting object, the cumulative number of times the above password setting object has set a password is three times, and setting the above historical password for the above password setting object is the third time to set a password for the above password setting object.

[0071] It should be noted that the above preset generation rule can be determined according to the actual situation. For example, the above preset generation rule can include combining a preset special character with the character used to describe the setting order of the historical password as the identification information of the historical password.

[0072] Optionally, the above preset generation rule can include the special character "@#", plus the character used to describe the setting order of any historical password, as the identification information of any historical password. For example, when a certain historical password is "12345678" and the character used to describe the setting order of the above historical password is "2", the identification information of the above historical password can include "@#2". The identification information of the above historical password can represent that setting the password "12345678" for the above password setting object is the second time to set a password for the above password setting object.

[0073] Optionally, the identification information of the historical password can be suffixed after the historical password or inserted before the historical password. In the embodiments of the present invention, the specific setting position of the identification information of the historical password is not limited.

[0074] It should be noted that after setting the historical password for the above password setting object and generating the identification information of the above historical password, the above historical password and the identification information of the above historical password can be stored in the ROM.

[0075] Step 103: Based on the historical password and the identification information of the historical password, perform a security check on the ROM and the current password.

[0076] Specifically, after obtaining the identification information of the historical password from the ROM, the security verification of the ROM can be performed in various ways based on the identification information of the historical password. For example, conditional judgment can be made based on the identification information of the historical password, and then it can be determined whether the ROM passes the security verification based on the result of the conditional judgment. In the embodiments of the present invention, the specific method for performing the security verification of the ROM based on the identification information of the historical password is not limited.

[0077] After obtaining the historical password from the ROM, it is also possible to verify whether the historical password is the same as the current password described above.

[0078] As an optional embodiment, based on the historical password and the identification information of the historical password, the security verification of the ROM and the current password includes: determining whether the historical password is the same as the current password, determining whether the identification information of the historical password matches the number of historical passwords, and in the case where the number of historical passwords is multiple, determining whether the identification information of the historical passwords is continuous.

[0079] It can be understood that the current password to be set this time cannot be the same as the historical password.

[0080] Since the identification information of the historical password can be used to describe the setting order of the historical password, therefore, in the case where there is no vulnerability in the ROM, the identification information of the historical password should match the number of historical passwords, and in the case where the number of historical passwords is multiple, the identification information of each historical password should be continuous.

[0081] For example, in the case where the identification information of the historical password includes "@#1", "@#2", "@#3" and "@#4", the number of historical passwords should be 4. If the number of historical passwords is not 4, it can be indicated that the ROM has been tampered with and the historical passwords stored in the ROM are invalid.

[0082] For another example, in the case where the identification information of the historical password only includes "@#1", the number of historical passwords should be 1. If the number of historical passwords is not 1, it can be indicated that the ROM has been tampered with and the historical passwords stored in the ROM are invalid.

[0083] For another example, in the case where the identification information of the historical password includes "@#1", "@#2", "@#3" and "@#4", it can be indicated that the identification information of the historical passwords is continuous. If the identification information of the historical password includes "@#1", "@#2" and "@#4", it indicates that the identification information of each historical password is not continuous, the ROM has been tampered with, and the historical passwords stored in the ROM are invalid.

[0084] In an embodiment of the present invention, it is possible to determine whether the ROM passes the security check by determining whether the historical password is the same as the current password, whether the identification information of the historical password matches the number of historical passwords, and, in the case where the number of historical passwords is multiple, determining whether the identification information of the historical passwords is consecutive.

[0085] After obtaining the historical password from the ROM, it is possible to determine whether the historical password is the same as the current password.

[0086] After obtaining the identification information of the historical password from the ROM, based on the identification information of the historical password, it is possible to obtain the maximum value among the characters used to describe the setting order of the historical password, and then it is possible to determine whether the number of historical passwords is the same as the above maximum value. In the case where the number of historical passwords is the same as the above maximum value, it can be determined that the identification information of the historical password matches the number of historical passwords; in the case where the number of historical passwords is not the same as the above maximum value, it can be determined that the identification information of the historical password does not match the number of historical passwords.

[0087] After obtaining the identification information of the historical password from the ROM, if the number of historical passwords is multiple, it is possible to determine whether the characters used to describe the setting order of the historical password in the identification information of each historical password are consecutive. If the above characters are consecutive, it can be determined that the identification information of each historical password is consecutive; if the above characters are not consecutive, it can be determined that the identification information of each historical password is not consecutive.

[0088] In the case where the historical password is different from the current password and the identification information of the historical password matches the number of historical passwords, or, in the case where the historical password is different from the current password, the number of historical passwords is multiple, the identification information of the historical password matches the number of historical passwords, and the identification information of the historical passwords is consecutive, it is determined that the ROM passes the security check.

[0089] Specifically, in the case where the number of historical passwords is one, if it is determined that the identification information of the historical password matches the number of historical passwords and the historical password is different from the current password, it can be determined that the ROM passes the security check;

[0090] In the case where the number of historical passwords is multiple, if it is determined that the historical password is different from the current password, the identification information of the historical password matches the number of historical passwords, and the identification information of each historical password is consecutive, it can be determined that the ROM passes the security check;

[0091] In the case where the number of historical passwords is one or more, if it is determined that the identification information of the historical password does not match the number of historical passwords, and / or, it is determined that the historical password is the same as the current password, it can be determined that the ROM fails the security check;

[0092] In the case where the number of historical passwords is multiple, if it is determined that the identification information of each historical password is not continuous, it can be determined that the ROM fails the security check.

[0093] Step 104: When it is determined that the ROM and the current password pass the security check, set the password for the password setting object based on the current password.

[0094] Specifically, when the ROM and the current password to be set this time pass the security check, the password of the above password setting object can be set to the above current password, and thus the password setting for the above device object this time can be completed.

[0095] As an optional embodiment, after setting the password for the password setting object based on the current password when it is determined that the ROM and the current password pass the security check, the method further includes: determining the current password as the target historical password of the password setting object, generating the identification information of the target historical password based on the setting order of the target historical password among all historical passwords, and storing the target historical password and the identification information of the target historical password in the ROM.

[0096] After setting the password of the above password setting object to the current password to be set this time, the above current password can be determined as the target historical password, and thus the identification information of the above target historical password can be generated based on the setting order of the above target historical password among all historical passwords of the password setting object and the above preset generation rule. Among them, the identification information of the above target historical password includes characters used to describe the setting order of the above target historical password among all historical passwords.

[0097] It should be noted that the above setting order of the target historical password can represent the cumulative number of times the password has been set for the above password setting object after setting the above target historical password for the above password setting object, usually the number of historical passwords obtained from the ROM plus 1, or the maximum value of the characters used to describe the setting order of the historical passwords in the identification information of the historical passwords plus 1. For example: in the case where the identification information of the historical passwords includes "@#1", "@#2", "@#3", and "@#4", the identification information of the current password can include "@#5".

[0098] After setting the above current password for the above password setting object, determining the above current password as the target historical password, and generating the identification information of the above target historical password, the above target historical password and the identification information of the above target historical password can be stored in the ROM for subsequent security check of the ROM when setting a password for the above password setting object.

[0099] It should be noted that after setting the above current password for the above password setting object, if it is necessary to verify the above current password, it is only necessary to verify whether the user's input is the same as the above current password, and it is not necessary to verify the identification information of the above current password.

[0100] In the embodiment of the present invention, when the historical password of the password setting object is found in the ROM, it is determined that setting the password for the password setting object this time is not the first time to set the password. Then, the identification information of the above historical password is obtained from the ROM. The identification information of any historical password includes characters used to describe the setting order of the above any historical password among all historical passwords. Based on the historical password and the identification information of the historical password, the security check of the ROM can be performed. When the ROM passes the security check, the password setting object is set with a password. It can effectively avoid the invalidation of the historical password stored in the ROM with only a small amount of computing resources consumed, improve the security of the ROM storing historical passwords, perform password setting more securely, and better ensure the security of the computer.

[0101] Based on the content of the above embodiments, when the current password to be set by the password setting object this time is obtained, after finding the historical password of the password setting object in the read-only memory ROM, the method further includes: when the historical password is not found in the ROM, obtaining the storage address of the ROM.

[0102] Specifically, if the historical password corresponding to the above password setting object is not found in the ROM, it can be determined that setting the password this time is the first time to set the password for the above password setting object.

[0103] When it is determined that setting the password this time is the first time to set the password for the above password setting object, the storage address in the ROM for storing the password can also be obtained.

[0104] Based on the storage address, perform a security check on the ROM.

[0105] Specifically, after obtaining the storage address in the ROM for storing the password, based on the above storage address, the ROM can be security-checked in various ways. For example: conditional judgment can be performed based on the above storage address, and based on the result of the conditional judgment, it can be determined whether the ROM passes the security check. In the embodiment of the present invention, the specific method for performing the security check on the ROM based on the above storage address is not limited.

[0106] As an optional embodiment, performing a security check on the ROM based on the storage address includes: judging whether the storage address is the same as a preset value.

[0107] Specifically, after obtaining the storage address in the ROM for storing the password, it can be determined whether the above storage address is the same as the preset value.

[0108] It should be noted that the above preset value can be determined based on prior knowledge and / or actual situations. In the embodiments of the present invention, the above preset value is not specifically limited.

[0109] When the storage address is the same as the preset value, it is determined that the ROM passes the security check.

[0110] If the above storage address is different from the preset value, it indicates that the ROM may have been tampered with, and it can be determined that the ROM fails the security check.

[0111] If the above storage address is the same as the preset value, it can be determined that the ROM passes the security check.

[0112] When it is determined that the ROM passes the security check, the password of the password setting object is set based on the current password.

[0113] Specifically, when the ROM passes the security check, the password of the above password setting object can be set to the current password to be set this time, and thus the password setting of the above device object can be completed.

[0114] The current password is determined as the first historical password of the password setting object, and then the identification information of the first historical password is generated, and the first historical password and the identification information of the first historical password are stored in the ROM.

[0115] Specifically, after setting the password of the above password setting object to the current password to be set this time, since this password setting is the first time to set a password for the above password setting object, the current password can be determined as the first historical password of the above password setting object, and then the identification information of the above first historical password can be generated based on the above preset generation rule. Among them, the identification information of the above first historical password includes the character "1", indicating that setting the above current password for the above password setting object is the first time to set a password for the above password setting object.

[0116] After setting the above current password for the above password setting object, determining the above current password as the first historical password of the above password setting object, and generating the identification information of the above first historical password, the above first historical password and the identification information of the above first historical password can be stored in the ROM for subsequent security check of the ROM when setting a password for the above password setting object.

[0117] In an embodiment of the present invention, when the historical password of the password setting object is found in the ROM, the storage address of the ROM is obtained, so that based on the above storage address, the security check of the ROM can be performed. When the ROM passes the security check, the first password setting of the above password setting object is performed, and after the first password setting of the above password setting object is completed, the above current password is determined as the first historical password of the above password setting object, the identification information of the above first historical password is generated, and the above first historical password and the identification information of the above first historical password are stored in the ROM, which can perform password setting more securely with only a small amount of computing resources when setting the password for the first time.

[0118] Based on the content of the above embodiments, after performing the security check on the ROM and the current password based on the historical password and the identification information of the historical password, the method further includes: when the ROM fails to pass the security check, display a first message on the user interaction interface, where the first message is used to prompt the user that there is a risk of the ROM being tampered with and ask the user whether to clear the ROM.

[0119] Specifically, when it is determined that the ROM fails to pass the security check based on the identification information of the historical password, the first message can be displayed on the user interaction interface, so as to prompt the user that the ROM has been tampered with and ask the user whether to clear the ROM.

[0120] Optionally, in an embodiment of the present invention, the above first message can be displayed on the user interaction interface in a pop-up window.

[0121] When receiving the second message representing the confirmation to clear the ROM input by the user based on the first message, the ROM is cleared through the Basic Input / Output System (BIOS).

[0122] Specifically, after the above first message for prompting the user that the ROM has been tampered with and asking the user whether to clear the ROM is displayed on the user interaction interface, if the second message representing the confirmation to clear the ROM input by the user based on the above first message is received, the ROM can be cleared through the BIOS.

[0123] Optionally, the BIOS can clear the section in the ROM for storing the historical password and the identification information of the historical password.

[0124] Based on the content of the above embodiments, after performing the security check on the ROM based on the storage address, the method further includes: when the ROM fails to pass the security check, display a first message on the user interaction interface, where the first message is used to prompt the user that there is a risk of the ROM being tampered with and ask the user whether to clear the ROM.

[0125] Specifically, when it is determined that the ROM fails the security check based on the storage address of the ROM, the first information can be displayed on the user interaction interface, so as to prompt the user that the ROM has been tampered with and ask the user whether to clear the ROM.

[0126] Optionally, in the embodiments of the present invention, the above first information can be encrypted and displayed in a pop-up window on the user interaction interface.

[0127] When receiving the second information indicating confirmation to clear the ROM input by the user based on the first information, the ROM is cleared through the BIOS.

[0128] Specifically, after the above first message for prompting the user that the ROM has been tampered with and asking the user whether to clear the ROM is displayed on the user interaction interface, if the second information indicating confirmation to clear the ROM is received based on the identification input by the user based on the above first message, the ROM can be cleared through the BIOS.

[0129] Optionally, the BIOS can clear the section in the ROM for storing passwords.

[0130] In the embodiments of the present invention, when the ROM fails the security check, the first message for prompting the user that the ROM has been tampered with and asking the user whether to clear the ROM is displayed on the user interaction interface, and when the second information indicating confirmation to clear the ROM is received based on the identification input by the user based on the above first message, the ROM is cleared through the BIOS, which can prompt the user of risks in a more timely manner. When there is a risk that the ROM has been tampered with, by clearing the ROM, the tampered data in the ROM can be cleared, which can further improve the security of storing historical passwords in the ROM and further improve the security of password setting.

[0131] Based on the content of the above embodiments, when the ROM and the current password pass the security check, after setting the password for the password setting object based on the current password, before storing the target historical password and the identification information of the target historical password into the ROM, the method further includes: when the number of historical passwords exceeds a preset value, based on the identification information of the historical passwords, deleting the historical password with the earliest setting order and the identification information of the historical password from the ROM.

[0132] Specifically, after obtaining the historical passwords from the ROM, it can be determined whether the number of historical passwords exceeds a preset value.

[0133] If the number of historical passwords exceeds a preset value, after setting the password of the above password setting object to the above current password and determining the above current password as the target historical password, before storing the above target historical password and the identification information of the above target historical password in the ROM, based on the characters in the identification information of the historical password used to describe the setting order of the historical password, delete the historical password with the earliest setting order and the identification information of the above historical password from the ROM.

[0134] For example, when the above preset value is 3 and the number of historical passwords obtained from the ROM is 4, and the identification information of each historical password includes "@#1", "@#2", "@#3", and "@#4", then based on the characters in the identification information of the above historical password used to describe the setting order of the historical password, it can be determined that the historical password with the identification information including "@#1" is the historical password with the earliest setting order, and the above historical password and the identification information of the above historical password can be deleted from the ROM.

[0135] It should be noted that the above preset value can be determined based on prior knowledge and / or actual situations. In the embodiments of the present invention, the above preset value is not specifically limited.

[0136] Optionally, after deleting the historical password with the earliest setting order and the identification information of the historical password from the ROM, the identification information of each existing historical password in the ROM can also be updated.

[0137] Figure 2 It is a schematic diagram of the shift of the identification information of the historical password updated in the password setting method provided by the present invention. As Figure 2 shown, after deleting the historical password with the earliest setting order and the identification information of the historical password from the ROM, the characters in the identification information of each historical password used to describe the setting order of the historical password can be advanced by 1 bit.

[0138] In the embodiments of the present invention, when the number of historical passwords obtained from the ROM exceeds the preset value, before storing the current password and the identification information of the current password in the ROM, based on the identification information of the historical password, deleting the historical password with the earliest setting order and the identification information of the historical password from the ROM can prevent the data volume stored in the ROM from being too large and causing the calculation speed to decrease.

[0139] To facilitate the understanding of the password setting method provided by the present invention, the following uses an example to illustrate the password setting method provided by the present invention.

[0140] Figure 3 It is the second schematic diagram of the process of the password setting method provided by the present invention. As Figure 3As shown, when the current password to be set this time is obtained, it is possible to check in the ROM whether there is a historical password.

[0141] If a historical password is found in the ROM, it can be determined that this password setting is not the first time to set a password for the above password setting object.

[0142] When it is determined that this password setting is not the first time to set a password for the above password setting object, the above historical password and the identification information of the above historical password can be obtained from the ROM.

[0143] After obtaining the identification information of the historical password from the ROM, the security of the ROM can be verified based on the identification information of the historical password. After obtaining the historical password from the ROM, it can also be verified whether the historical password is the same as the above current password.

[0144] When the ROM and the current password to be set this time pass the security verification, the password of the above password setting object can be set to the above current password, and then the password setting for the above device object can be completed this time.

[0145] If the historical password corresponding to the above password setting object is not found in the ROM, it can be determined that this password setting is the first time to set a password for the above password setting object.

[0146] After setting the password of the above password setting object to the current password to be set this time, the above current password can be determined as the target historical password, and the identification information of the above target historical password can be generated based on the setting order of the above target historical password among all historical passwords and the above preset generation rule.

[0147] After generating the identification information of the above target historical password, the above target historical password and the above target historical password can be stored in the ROM for security verification of the ROM when setting a password for the above password setting object next time.

[0148] When it is determined that this password setting is the first time to set a password for the above password setting object, the storage address in the ROM for storing passwords can also be obtained.

[0149] After obtaining the storage address in the ROM for storing passwords, it can be determined whether the above storage address is the same as the preset value.

[0150] If the above storage address is the same as the preset value, it can be determined that the ROM passes the security verification.

[0151] When the ROM passes the security verification, the password of the above password setting object can be set to the current password to be set this time, and then the password setting for the above device object can be completed.

[0152] After setting the password of the above password setting object to the current password to be set this time, the above current password can be determined as the first historical password of the above password setting object, and the identification information of the above first historical password can be generated based on the above preset generation rule.

[0153] After generating the identification information of the above first historical password, the above first historical password and the above first historical password can be stored in the ROM for security verification of the ROM when setting the password for the above password setting object next time.

[0154] Figure 4 It is the third flowchart of the password setting method provided by the present invention. As Figure 4 shown, after obtaining the historical password from the ROM, it can be determined whether the number of historical passwords exceeds a preset value.

[0155] If the number of historical passwords exceeds the preset value, then after setting the password of the above password setting object to the above current password and determining the above current password as the target historical password, before storing the above target historical password and the identification information of the above target historical password in the ROM, based on the character used to describe the setting order of the historical password in the identification information of the historical password, the historical password with the earliest setting order and the identification information of the above historical password are deleted from the ROM.

[0156] After deleting the historical password with the earliest setting order and the identification information of the historical password from the ROM, the identification information of each existing historical password in the ROM can also be updated.

[0157] Figure 5 It is the structural schematic diagram of the password setting device provided by the present invention.

In the embodiments of the present invention, the specific manner of obtaining the current password to be set is not limited.

[0164] After obtaining the current password to be set, the data search module 501 can also search for the historical password corresponding to the password setting object in the ROM.

[0165] If the historical password corresponding to the password setting object is found in the ROM, the data acquisition module 502 can obtain the historical password and the identification information of the historical password from the ROM.

[0166] After obtaining the identification information of the historical password from the ROM, the security verification module 503 can perform security verification on the ROM in various ways based on the identification information of the historical password. For example, it can perform conditional judgment based on the identification information of the historical password, and then determine whether the ROM passes the security verification based on the conditional judgment result. In the embodiments of the present invention, the specific manner of performing security verification on the ROM based on the identification information of the historical password is not limited.

[0167] When the ROM and the current password to be set pass the security verification, the password setting module 504 can set the password of the password setting object to the current password, and thus complete the password setting for the device object this time.

[0168] Optionally, the password setting device may further include a data storage module.

[0169] The data storage module can be configured to determine the current password as the target historical password of the password setting object, generate the identification information of the target historical password based on the setting order of the target historical password among all historical passwords, and store the target historical password and the identification information of the target historical password in the ROM.

[0170] Optionally, the data lookup module 501 can also be used to obtain the storage address of the ROM when the historical password cannot be found in the ROM; based on the storage address, perform a security check on the ROM; when it is determined that the ROM passes the security check, set the password for the password setting object based on the current password; determine the current password as the first historical password of the password setting object, and then generate identification information for the first historical password, and store the first historical password and the identification information of the first historical password in the ROM.

[0171] Optionally, the security check module 503 can specifically be used to determine whether the historical password is the same as the current password, determine whether the identification information of the historical password matches the number of historical passwords, and when there are multiple historical passwords, determine whether the identification information of the historical passwords is continuous; when the historical password is different from the current password and the identification information of the historical password matches the number of historical passwords, or, when the historical password is different from the current password, there are multiple historical passwords, the identification information of the historical password matches the number of historical passwords, and the identification information of the historical passwords is continuous, it is determined that the ROM passes the security check.

[0172] Optionally, the security check module 503 can specifically be used to determine whether the storage address is the same as a preset value; when the storage address is the same as the preset value, it is determined that the ROM passes the security check.

[0173] Optionally, the password setting device can also include an alarm module.

[0174] The alarm module can be used to display a first message on the user interface when the ROM fails the security check. The first message is used to prompt the user that there is a risk of the ROM being tampered with and ask the user whether to clear the ROM; when receiving a second message indicating confirmation to clear the ROM input by the user based on the first message, clear the ROM through the Basic Input / Output System (BIOS).

[0175] Optionally, the password setting device can also include a historical password update module.

[0176] The historical password update module can be used to delete the historical password with the earliest setting order and the identification information of the historical password from the ROM based on the identification information of the historical password when the number of historical passwords exceeds the preset value.
