Detailed Description
In order to make the object technical scheme and advantages of the present invention more apparent, the following embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the embodiments of the present invention, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present invention, and the following embodiments are not described one by one.
As shown in fig. 1, the present invention provides a method for starting up a server BIOS fingerprint, including:
s1, acquiring a fingerprint image of a user, and generating a fingerprint identification code according to the fingerprint image;
s2, generating the GUID of the fingerprint image according to the GUID generation algorithm of the BIOS based on the fingerprint identification code;
and step S3, searching the GUID of the fingerprint image in the BIOS, and storing the fingerprint image into a storage space corresponding to the GUID and starting up the server in response to the existence of the GUID.
The method provided by the invention is to execute the program in the starting stage of the BIOS, and in the development process of the firmware of the AMD chip server, the corresponding Protocol is mounted on the corresponding function driver by adding the corresponding function driver to the BIOS driver database in the starting process of the BIOS, so that the function to be realized is compiled into the BIOS program, therefore, in the embodiment, the verification driver for realizing the fingerprint identification can be mounted on the BIOS driver database (called as BIOS architecture for indicating the program to be loaded in the starting process of the BIOS) according to the BIOS operation rule of the AMD server. After BIOS is started, corresponding logic is executed to process the fingerprint identification code transmitted by the fingerprint identification module so as to realize the safety problem of fingerprint identification on BIOS starting and guiding the operating system.
Also, different fingerprint authentication programs may be loaded into the BIOS according to the BIOS's boot mechanism for different CPU platforms.
In this embodiment, in step S1, a fingerprint image of a user is obtained by an external fingerprint acquisition device connected to the BIOS, and an identification code of a fingerprint of the user is calculated according to a fingerprint identification algorithm of the fingerprint acquisition device. In this embodiment, the fingerprint acquisition device may use any form of fingerprint acquisition device, and has a function of outputting a fingerprint identification code. The fingerprint device of the universal trusted algorithm can be selected, and the device using the customized fingerprint algorithm can also be selected. The fingerprint acquisition device calculates the fingerprint of the user by adopting a correlation algorithm and then sends the calculated fingerprint to a corresponding fingerprint verification program in the BIOS.
In step S2, after the BIOS receives the fingerprint identification code sent by the corresponding fingerprint acquisition device, the fingerprint identification code is generated into a GUID according to the GUID generation algorithm that assigns the GUID to the driver in the BIOS.
In step S3, after obtaining the GUID of the fingerprint, the GUID of the fingerprint is searched in the BIOS in a manner of searching the functional driver of the BIOS, if the GUID exists in the BIOS, it is indicated that the fingerprint detected by the fingerprint device is correct, fingerprint authentication is completed in the BIOS stage, and corresponding other functional programs are loaded through the GUIDs of the other functional programs according to the established BIOS startup procedure, so as to complete booting of the operating system. And storing a fingerprint image acquired by the fingerprint at the fingerprint acquisition device in a memory space of the BIOS according to the GUID of the fingerprint.
In some embodiments of the present invention, a digital-to-analog conversion module is added between fingerprint acquisition devices to convert a fingerprint image acquired by a fingerprint acquisition device into a digital signal, and the digital signal is stored in a storage space of a BIOS corresponding to a GUID of the fingerprint.
It should be noted that, the GUID mentioned in the present invention is a unique identifier of a driver for identifying the BIOS, that is, a driver is a GUID, and in addition, the driver may be understood as other devices on the BIOS control server or a functional program for driving the other devices. The BIOS finds out the corresponding code data of the drive sequence in the memory space of the BIOS according to the GUID and loads the code data to realize the corresponding function.
Thus, the GUID of the fingerprint in the present invention does not correspond to a driver, which corresponds to a default fingerprint image stored in the memory space of the BIOS, and a temporarily acquired fingerprint image for fingerprint verification at start-up.
In some embodiments of the present invention, acquiring a fingerprint image of a user and generating a fingerprint identification code from the fingerprint image includes:
in response to acquiring a fingerprint image of the user, dividing the fingerprint image into a first predetermined number of feature images according to a first predetermined number; and
and respectively calculating the identification codes of the characteristic images and the fingerprint images corresponding to the first preset number of characteristic images and the fingerprint images.
In this embodiment, the fingerprint image of the user is split into a plurality of feature images, and the identification codes of the corresponding feature images are calculated respectively. For example, in some embodiments of the present invention, the fingerprint image is divided into 9 regions in a nine-grid manner, and corresponding 9 identification codes are generated on the images of the 9 regions according to a fingerprint identification algorithm. In some embodiments of the present invention, when generating a plurality of feature identifiers, correction is required to be performed on a fingerprint image, that is, the size of the fingerprint image is reselected according to the boundaries of the fingerprints in the fingerprint image, then the selected area is used as the fingerprint image, and the fingerprint image is segmented to obtain a plurality of fingerprint features, so as to calculate a plurality of feature identifiers.
In some embodiments of the present invention, the fingerprint acquisition device also needs to send the currently acquired fingerprint image to the BIOS for temporary storage.
In some embodiments of the invention, the method further comprises:
generating the GUIDs of the first preset number of characteristic images based on the GUID generation algorithm of the BIOS in response to the fact that the GUIDs do not exist in the BIOS;
judging whether the GUIDs of the first preset number of characteristic images exist in a storage space corresponding to the preset GUIDs in the BIOS;
and starting the server in response to the GUIDs of the characteristic images with the first preset number in the storage space corresponding to the preset GUIDs in the BIOS.
In this embodiment, the predetermined GUID refers to that when a fingerprint is input, the GUID fingerprint acquisition device generated according to the first input fingerprint sends a fingerprint identification code obtained by calculating a fingerprint image to the BIOS, and the BIOS generates a GUID by using the fingerprint identification code, if no corresponding GUID is found when the GUID is queried, it is indicated that the fingerprint acquired by the fingerprint acquisition device is not matched with a default fingerprint, so that the generated fingerprint identification code is not matched when passing through the same GUID generation algorithm, and cannot be matched in the existing GUIDs of the BIOS, so that the condition that the GUID of the generated fingerprint is not found when being queried does not exist.
In some cases, however, there is a deviation in the fingerprint image captured by the fingerprint capture device due to the problem of placement of the user's finger, so that the generated fingerprint identification code is different from the correct fingerprint identification. In order to improve the fingerprint identification efficiency, in this example, if there is a situation that the fingerprint identification codes obtained by the complete fingerprint image are not matched after generating the GUID in the BIOS, after the BIOS sends the fingerprint identification code authentication failure to the fingerprint acquisition device, the fingerprint acquisition device divides the fingerprint image into a plurality of feature images according to the above manner, calculates the feature identification codes corresponding to the plurality of feature images respectively, then sends the feature identification to the BIOS, calculates the corresponding GUID by the received plurality of feature identification codes respectively, after calculating the GUID respectively, matches the GUID of the plurality of feature identification codes with the GUID of a storage space corresponding to another specified GUID for storing the plurality of feature GUIDs respectively, and if the number of the GUIDs contained in the storage space of the specified GUID matched with the GUIDs of the plurality of feature identification codes verified by the fingerprint reaches 7 (in the case that the identification codes of the feature images are 9), considers the fingerprint acquired by the fingerprint acquisition device to be safe, and even if the fingerprint authentication of the complete fingerprint image fails.
It should be noted that, in the above embodiment of the present invention, the GUID for storing the plurality of feature identifiers is a specially set GUID, similar to the GUID corresponding to other driving programs, and is not generated by the identifiers of the plurality of feature images or fingerprint images, but is used for identifying and storing the plurality of GUIDs corresponding to the plurality of feature identifiers, because the corresponding GUID is searched in the BIOS to locate the corresponding storage space. The GUID used for saving the fingerprint image in the above embodiment is the GUID generated by the identification code of the fingerprint image when the fingerprint is first entered.
In some embodiments of the invention, the method further comprises:
responding to the first starting of the server, and generating the GUID of the fingerprint image according to the GUID generation algorithm of the BIOS based on the identification code of the fingerprint image;
and mounting the GUID of the fingerprint image on a driver of the BIOS and storing the fingerprint image as a default fingerprint image into a storage space corresponding to the GUID.
In this embodiment, when the server starts to enter a fingerprint for the first time, the identification code of the fingerprint image acquired by the fingerprint acquisition device generates a GUID for storing the fingerprint image and for fingerprint verification according to the GUID generation algorithm based on the identification code, takes the fingerprint image as a default fingerprint image, stores the fingerprint image in the storage space of the BIOS, and simultaneously establishes a connection between the GUID and the corresponding storage space. In addition, the GUID is used as the GUID of one driver, but is not used in a manner of calling other drivers. And only searching the GUID by using a searching mode of a driver in the subsequent fingerprint verification of the starting-up process.
In some embodiments of the invention, the method further comprises:
and storing the GUIDs of the characteristic images generated by a preset number of characteristic images of the fingerprint images based on the GUID algorithm of the BIOS into a storage space corresponding to the preset GUIDs.
In some embodiments of the invention, the method further comprises:
responding to the starting of the server, guiding the server to enter an operating system by the BIOS, and sending the fingerprint image and a default fingerprint image stored in the BIOS to the operating system;
the operating system verifies whether the fingerprint image and the default fingerprint image are identical according to an image recognition algorithm;
and responding to the fingerprint image being different from the default fingerprint image, reporting an exception by the operating system, locking the BIOS and closing the server.
In this embodiment, after the fingerprint verification in the BIOS stage passes, for security, after entering the operating system, the BIOS sends the fingerprint image of the fingerprint verification and the fingerprint image of the first entry to the operating system, and the image recognition algorithm in the operating system compares and verifies the fingerprint image and the fingerprint image of the first entry again, and if the verification result is the same fingerprint, the operating system operates normally. If the verification results are different, reporting errors newly to a server management system or other early warning, and simultaneously sending a locking instruction to the BIOS to prevent the BIOS from booting functions in the restarting process of the subsequent server.
In some embodiments of the invention, the method further comprises:
in response to the fingerprint image being the same as the default fingerprint image, the operating system will send a delete instruction to the BIOS, which will delete the fingerprint image.
In this embodiment, if the result of the image recognition in the operating system is the same, after the operating system is started normally, an instruction for deleting data is sent to the BIOS, and the stored fingerprint image verified by the fingerprint is deleted.
The method for starting the server BIOS fingerprint provided by the invention can be used for controlling the BIOS fingerprint to start to be executed by the BIOS without any verification calculation in the BIOS, and meanwhile, the original task mechanism of the BIOS is utilized to realize the embedding and fusion of the fingerprint authentication mechanism and the task execution of the BIOS, so that the security of fingerprint authentication is ensured, the calculation capability of the BIOS is not consumed, and a fingerprint authentication solution with excellent performance is provided.
