[0044] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0045] Figure 1 It is a flow chart of a laboratory access control management method based on identity authentication according to an embodiment of the present invention;

[0046] Figure 2 It is a structural diagram of a laboratory access control management system based on identity authentication according to an embodiment of the present invention. DETAILED DESCRIPTION

[0047] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects disclosed in the present invention, so as to fully understand the purpose, scheme and effect disclosed in the present invention. It should be noted that the embodiments and features in the embodiments in this application can be combined with each other without conflict.

[0048] refer to Figure 1 ,like Figure 1 The present invention provides a laboratory access control management method based on identity authentication, which includes the following steps:

[0049] S100, obtaining reservation information for applying to enter a laboratory, the reservation information including identity information, a timestamp for sending the reservation information, a time period for entering the laboratory, and an experimental subject;

[0050] It should be noted that identity information includes the user's biometric information (such as fingerprint information, face information, etc.) and student information (such as name, student number, etc.), and experimental subjects include experimental course names, experimental course numbers, etc. Identity information is obtained with the user's consent.

[0051] S200, if it is determined that the identity information in the reservation information exists in the authorization information library, the identity information is marked in the authorization information library, and the reservation information containing the identity information is used as the first reservation information; wherein the authorization information library includes a plurality of identity information and authorization information corresponding to the plurality of identity information one by one;

[0052] It should be noted that if the identity information is not in the authorization information library, it means that the user is a new user and needs to be reported to the super administrator who has set up the laboratory access control management system. The super administrator adds the user's identity information to the authorization information library and sets the effective time period for entering the laboratory.

[0053] S300, determining the start time of the time period, calculating the interval time between the timestamp and the start time, and selecting the reservation information whose interval time is less than a first time threshold and greater than a second time threshold as the second reservation information;

[0054] It should be noted that the first duration threshold and the second duration threshold can be set according to the actual needs and safety requirements of the laboratory. It can be understood that the first duration threshold is greater than the second duration threshold. In some embodiments, the first duration threshold can be set to 7 days and the second duration threshold can be set to 1 day. In this way, only the reservation information whose timestamp in the reservation information is between 1 and 7 days from the start time will be selected as the second reservation information.

[0055] S400, obtaining course records of the identity information corresponding to the second reservation information in the past time period, and determining the course credibility of the second reservation information based on the course records and the experimental subjects in the second reservation information; wherein the course credibility indicates the probability that the experimental subjects in the second reservation information are true;

[0056] It should be noted that the past time period can be set according to the actual teaching situation, for example, the past month, a semester or a year can be selected. The course record includes the experimental subject, professional category, and experimental frequency recorded after the user is authorized to enter the laboratory.

[0057] S500: updating the authorization information in the authorization information database based on the course credibility of the second reservation information, and performing access control based on the updated authorization information database.

[0058] It should be noted that, in some embodiments, after the authorization information database is updated, the updated authorization information database is sent to the identity authentication device, and identity authentication is performed through the identity authentication device (such as a fingerprint reader, face recognizer, etc.); after the identity authentication device collects the identity information in the second reservation information, it opens the laboratory door.

[0059] As an improvement of the above embodiment, in S400, the course credibility of the second reservation information is determined based on the course record and the experimental subject in the second reservation information;

[0060] S410, determining the professional category with the highest professional affiliation based on the course record as the predicted professional category; wherein the course record includes the professional category, experiment frequency, authorization times and pass rate, and the professional affiliation is used to represent the degree to which the experimental subject in the second reservation information belongs to the professional category in the course record;

[0061] It should be noted that professional affiliation is used to characterize the degree to which the experimental subject belongs to the professional category, which can be obtained by calculating factors such as experimental frequency, number of authorizations and pass rate.

[0062] S420, taking the professional category to which the experimental subject in the second reservation information belongs as the reference professional category, and determining whether the reference professional category is consistent with the predicted professional category; if so, executing S430; if not, executing S480;

[0063] It should be noted that if the baseline major category is consistent with the predicted major category, it means that the experimental subjects in the second reservation information have a high correlation with the experimental subjects of the user's laboratory training in the past time period, and the second reservation information has preliminary course credibility; if the baseline major category is inconsistent with the predicted major category, it means that the experimental subjects have undergone major changes, and the course credibility of the second reservation information is low, which requires strengthened verification.

[0064] S430, calculating a first correlation degree and a second correlation degree of the second reservation information, and if it is determined that the first correlation degree is greater than a first correlation threshold, executing S440, otherwise executing S450; wherein the first correlation degree represents the consistency between the experimental subjects in the second reservation information and the experimental subjects in the individual historical information, and the individual historical information is the reservation information of the identity information in the second reservation information in the past time period; the second correlation degree represents the consistency between the experimental subjects in the second reservation information and the experimental subjects in the first reservation information;

[0065] S440, determining whether the second correlation degree is greater than a second correlation threshold, if so, executing S470; otherwise, executing S480;

[0066] S450, determining whether the second correlation degree is greater than a second correlation threshold, if so, executing S460; otherwise, executing S480;

[0067] S460, calculating a third correlation degree, and if the third correlation degree is greater than a third correlation threshold, executing S470; otherwise executing S480; wherein the third correlation degree represents the consistency between the professional category in the second reservation information and the professional category in the group historical information, and the group historical information is the reservation information of the identity information in the second reservation information in the past time period;

[0068] S470, setting the course credibility of the second reservation information to be credible;

[0069] S480: Setting the course credibility of the second reservation information to untrustworthy.

[0070] It should be noted that the first correlation threshold, the second correlation threshold and the third correlation threshold are preset to limit the minimum correlation. Exemplarily, the value range of the first correlation threshold, the second correlation threshold and the third correlation threshold is 0.6 to 0.9. By combining the first correlation, the second correlation and the third correlation, the course credibility of the second reservation information can be more comprehensively evaluated. The following is a detailed classification description of the course credibility of the second reservation information:

[0071] calculating a first relevance and a second relevance of the second reservation information;

[0072] If it is determined that the first correlation degree is greater than a first correlation threshold, and the second correlation degree is greater than a second correlation threshold, setting the course credibility of the second reservation information to be credible;

[0073] Specifically, the consistency of the experimental subjects in the reservation information with the past experimental subjects can be determined through the first correlation, thereby determining the validity of the reservation information. If the first correlation is high, it means that the experimental subjects are consistent and the course credibility is high. If the first correlation is low, it means that the consistency is poor and the course credibility is low. However, the first correlation cannot fully reflect the validity of the reservation information, because the course may undergo major changes. This embodiment combines the second correlation for further verification. By combining the second correlation, it is verified whether the reservation information is consistent with the reservation information of the same period. If the second correlation is high, it means that the experimental subjects of the second reservation information are consistent with those of the first reservation information, and the second reservation information has a high course credibility.

[0074] If it is determined that the first correlation degree is greater than a first correlation threshold, and the second correlation degree is less than a second correlation threshold, setting the course credibility of the second reservation information to untrustworthy;

[0075] Specifically, if the first correlation is high and the second correlation is low, it means that the experimental subject of the second reservation information maintains a high degree of consistency, but the second reservation information is significantly different from the first reservation information and needs further verification. The user may be required to provide more information, such as course certification, teacher authorization, etc., to confirm the authenticity of the experimental subject. If the user can provide sufficient evidence to prove the authenticity of the experimental subject, it can be updated to the authorization information library. If the user cannot provide sufficient evidence, the authorization information library is refused to be updated and the user is notified that the reservation failed.

[0076] If it is determined that the first degree of association is less than a first degree of association threshold, and the second degree of association is greater than a second degree of association threshold, a third degree of association is calculated, and if the third degree of association is greater than the third degree of association threshold, the course credibility of the second reservation information is set to be credible; otherwise, the course credibility of the second reservation information is set to be uncredible;

[0077] Specifically, if the first correlation is low and the second correlation is high, it means that the experimental subject of the second reservation information has undergone a major change, but the experimental subject of the second reservation information is still highly consistent with that of the first reservation information. If it is verified that the second reservation information and the first reservation information have the same experimental subject changes, it means that the second reservation information has a high course credibility; through the third correlation, the course credibility of the second reservation information can be more comprehensively evaluated. If the third correlation is high, it means that the second reservation information has a high course credibility in terms of experimental subjects and consistency of reservation information in the current and past time periods. If the third correlation is low, it means that the course credibility of the second reservation information in these two aspects is not high and needs further verification.

[0078] If it is determined that the first correlation degree is less than a first correlation threshold, and the second correlation degree is less than a second correlation threshold, setting the course credibility of the second reservation information to untrustworthy;

[0079] Specifically, if both the first correlation and the second correlation are low, it means that the experimental subjects of the second reservation information have undergone major changes, and the experimental subjects in the second reservation information are greatly different from those in the first reservation information. The course credibility of the second reservation information is low and needs to be strengthened.

[0080] As an improvement of the above embodiment, in S410, the professional category with the highest professional affiliation is determined based on the course records as the predicted professional category;

[0081] S411, recording the course record of the identity information corresponding to the second reservation information in the past time period as the first individual history record; wherein the course record includes the experimental subject, professional category, and experimental frequency, and the experimental frequency indicates the ratio of the time interval of the user entering the laboratory in a certain professional category to the duration of the past time period;

[0082] S412, counting the experimental subjects included in each professional category in the first individual historical record, determining the weight of the experimental subjects based on the experimental frequency of the experimental subjects, determining the professional affiliation corresponding to the professional category according to the number of experimental subjects in the professional category and the weight of the experimental subjects, and taking the professional category with the highest professional affiliation as the predicted professional category.

[0083] It should be noted that the number of subjects indicates the number of categories of experimental subjects, and the experimental frequency reflects the frequency of experimental subjects. After counting the experimental frequencies of experimental subjects, the experimental frequencies of each experimental subject are normalized based on the total experimental frequency, and the sum of the weights of all experimental subjects is set to 1 to obtain the weight of the experimental subject. The more the number of experimental subjects in a professional category, the higher the experimental frequency of the experimental subjects, indicating that the professional category is the main major, which is used as the predicted professional category.

[0084] As an improvement of the above embodiment, the first correlation degree is obtained by the following method:

[0085] Taking the experimental subject in the second reservation information as the target subject, and determining the professional category to which the target subject belongs;

[0086] The remaining experimental subjects in the professional category except the target subject are regarded as the same subjects as the target subject;

[0087] The experiment frequency, duration and appointment pass rate of the same subject are obtained from the individual historical information, the weight of the same subject is determined based on the experiment frequency of the same subject, and the product of the weight of the same subject and the appointment pass rate is used as the modified weight;

[0088] It should be noted that, in this embodiment, the duration indicates the length of the time period for entering the laboratory, and the reservation pass rate indicates the proportion of reservation information for the target subject that is authorized; the weights of similar subjects are determined in the same manner as in the above embodiment. Specifically, after counting the experimental frequencies of similar subjects in individual historical information, the experimental frequencies of each similar subject are normalized based on the total experimental frequency, and the sum of the weights of all similar subjects is set to 1 to obtain the weights of similar subjects. Correcting the weights by the reservation pass rate can more accurately reflect the course credibility of similar subjects. If the reservation pass rate is high, it means that the reservation information related to the similar subject has a high course credibility.

[0089] The duration of each similar subject in the individual history information is obtained, and a first degree of association is determined based on the correction weight, the duration of the target subject, and the duration of each similar subject.

[0090] Optionally, the calculation formula of the first correlation degree is:

[0091] ;

[0092] in, represents the duration of the i-th similar subject, It represents the average duration of all similar subjects in the professional category. represents the modified weight of the ith similar subject, Indicates the duration of the target subject, Represents the total number of all similar subjects in the stated professional category.

[0093] As an improvement of the above embodiment, the second association degree is obtained by:

[0094] Taking the experimental subject in the first reservation information as a reference subject, calculating the overlapping time periods of the experimental subject in the second reservation information and the reference subject respectively, and determining the reference subject whose overlapping time period exceeds the time period threshold as a valid subject;

[0095] It should be noted that the reservation information may include multiple experimental subjects and thus have multiple time periods. However, the first reservation information should have an overlapping time period with the second reservation information, and the overlapping time period at least includes the time of an experimental class. In some embodiments, the time deviation threshold is set to the time of an experimental class, for example 45 minutes; if the overlapping time period is lower than the time period threshold, it is considered that the corresponding first reservation information is not strongly associated with the second reservation information.

[0096] The ratio of the number of the valid subjects to the number of the reference subjects is used as a first coefficient, and the ratio of the overlapping period of the valid subjects to the time period is used as a weight of the valid subjects;

[0097] The first degree of association of each valid subject in the group history information is obtained, and the products of the first degree of association of each valid subject and the weight are added up and multiplied by a first coefficient to obtain a second degree of association.

[0098] In this embodiment, the first coefficient represents the ratio of the number of valid subjects to the number of reference subjects, reflecting the matching degree of the experimental subjects; the ratio of the overlapping time period of valid subjects to the time period represents the overlapping degree of valid subjects, reflecting the correlation degree of the experimental subjects; the first correlation degree represents the course credibility of the valid subjects in the individual historical information, reflecting the reliability of the experimental subjects in the second reservation information. Through the comprehensive evaluation of these three dimensions, the consistency of the experimental subjects in the second reservation information and the experimental subjects in the first reservation information can be judged more comprehensively, which improves the accuracy of the course credibility judgment.

[0099] As an improvement of the above embodiment, the third degree of association is obtained in the following manner:

[0100] Calculate the mean vector corresponding to each professional category in the individual historical record;

[0101] An individual distribution degree matrix of the individual historical records and a group distribution degree matrix of the group historical records are determined respectively according to the mean vector, and a ratio of the individual distribution degree matrix to the group distribution degree matrix is ​​used as a third correlation degree.

[0102] Specifically, determining the individual distribution degree matrix of the individual historical records and the group distribution degree matrix of the group historical records respectively according to the mean vector, and taking the ratio of the individual distribution degree matrix to the group distribution degree matrix as the third correlation degree, includes:

[0103] The individual history record is recorded as , is an n×m matrix, where n represents the total number of professional categories in the individual historical records, and m represents the total number of experimental subjects in the professional category;

[0104] The mean vector of the jth professional category in the individual's historical record is calculated by the following formula:

[0105] ;

[0106] in, represents the mean vector of the jth professional category, represents the experimental frequency of the i-th experimental subject in the j-th professional category, represents the experimental frequency of all experimental subjects in the individual's historical records; represents the total number of experimental subjects included in the jth professional category;

[0107] The subject distribution matrix of the jth professional category is calculated by the following formula: :

[0108] ;

[0109] Sum the subject distribution matrices of all professional categories to obtain the individual distribution matrix of individual historical records :

[0110] ;

[0111] The group distribution matrix of group historical information is calculated by the following formula :

[0112] ;in, Represents the mean vector of the jth professional category in the group's historical information;

[0113] By formula Calculate the third correlation .

[0114] As an improvement of the above embodiment, in S500, updating the authorization information in the authorization information database based on the course credibility of the second reservation information, and performing access control based on the updated authorization information database, includes:

[0115] If the course credibility of the second reservation information is set to be credible, obtaining the total number of the second reservation information set to be credible as the first number;

[0116] Determine the total number of first reservation information having the same experimental subject as the second reservation information as the second number;

[0117] Determine whether the ratio of the first number to the second number is greater than a ratio threshold; if so, update the authorization information in the authorization information library based on the first reservation information; otherwise, update the authorization information in the authorization information library based on the course credibility of the second reservation information.

[0118] It should be noted that the ratio threshold is pre-set and can be 60% to 100%. If it is determined whether the ratio of the first quantity to the second quantity is greater than the ratio threshold, the first appointment information is authorized, and the authorization information corresponding to the identity information in the first appointment information is updated in the authorization information library to allow entry to the laboratory within the time period, thereby authorizing all appointment information existing in the authorization information library; otherwise, the authorization information corresponding to the identity information in the second appointment information is updated in the authorization information library to allow entry to the laboratory within the time period, and only the second appointment information that has passed the verification is authorized.
