The hardware structure and functions of the related devices of the present invention have been described in detail so far. Hereinafter, various embodiments of the present invention will be proposed based on the above-described hardware structure and function.
The invention provides an access control password verification method.
Fig. 3 is a schematic flow chart of a method for verifying an access control password according to embodiment 1 of the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 3 may be changed and some steps may be omitted according to different requirements.
In this embodiment, the access control password verification method includes:
and S101, receiving an entrance guard password input by a user, wherein the entrance guard password is a digital password.
In this embodiment, be provided with a plurality of entrance guard's equipment 2 in the wisdom community, 2 accessible networks of entrance guard's equipment and 1 communication connection of community platform are used for in the user business turn over when the wisdom community is distinguished, the accessible sets up in 2 notice relevant personnel in the community of entrance guard's equipment of community access way, in order to acquire to open the authority of opening entrance guard's equipment 2, the user business turn over of being convenient for the community. It should be noted that the user described in this embodiment may be a community owner or a visitor. Generally, the access control device 2 may be provided with a password input unit 13, such as a numeric keypad and/or a touch screen. The user can enter specific information through the password input unit 13, preferably, a room number of the owner's own home or a home to be visited is input to inform the visitor of the visit.
In this embodiment, when the access control device 2 receives information input by a user, the access control device 2 generates an access request according to the information input by the user, and sends the access request to the community platform 1. For example, the access request may be "request direction 808 house owner" or the like. Correspondingly, after the community platform 1 receives the access request, the room number input by the user is firstly obtained through the access request; then, inquiring a corresponding community owner account number which is registered in the community platform 1 in advance by the community owner according to the room number; then generating an access authorization application according to the access request and the community owner account; and finally, the community platform 1 is matched with a client program through installation in the owner terminal 3, and the community owner account is sent to the access authorization application to remind the community owner that the visitor visits and whether the access equipment 2 is opened to allow the visitor to enter and exit the community.
It can be understood that after the community platform 1 initiates the access authorization application to the corresponding owner account, it can further detect whether the corresponding application feedback is received within the preset time. If the application feedback is received, judging that the owner terminal 3 has received the access authorization application; if the application feedback is not received, the owner terminal 3 is judged not to receive the access authorization application. Wherein the preset time is preferably 1 minute.
In this embodiment, when the owner terminal 3 receives the access authorization application, the owner terminal 3 displays the access authorization application, and feeds back, to the community platform 1, the user operation based on the access authorization application made by the community owner. The user operation at least comprises preset authorization operation and refusal authorization operation. For example, an operation page may be displayed, where the operation page includes an authorization button and a denial authorization button, and the user may click the buttons to complete corresponding authorization and denial authorization operations.
Further, when the community platform 1 receives the user operation fed back by the owner terminal 3, the community platform 1 detects whether the user operation is a preset authorization operation or a refusal authorization operation; if so, responding to the authorization operation and the authorization operation refusing to generate a corresponding access control instruction and sending the access control instruction to the access control equipment 2, so that the access control equipment 2 responds to the access control instruction to open and close the access control.
It can be understood that the access control instruction can be an operation instruction for directly controlling the opening and closing of the access control device 2, and can also be an access control password to be verified. For promoting the security of community, the preferred entrance guard's password of this embodiment, treat that the entrance guard's password is preferably digital password. That is, when the community platform 1 detects that the user operation is a preset authorization operation and a preset authorization rejection operation, the community platform 1 responds to the authorization operation and the authorization rejection operation, and sends an access password to the access control device 2. If the operation is authorized, sending a correct access control password; and if the operation is the refusal of the authorization operation, sending an incorrect entrance guard password. Therefore, the access control equipment 2 can be used for verifying the access control password and then opening or closing the access control. The generation step of the correct access control password will be described in detail later.
And S102, inquiring the number of the marks in the access control password.
As described above, in this embodiment, the access code is preferably a digital code, and the digital code may be a 6-digit number, where the 1 st digit is preferably a flag number of the access code. It can be understood that the 6-digit digital code is easy to remember and convenient for users to use. Therefore, in this embodiment, the access control password is preferably a 6-digit digital password. The generation method of the 6-digit digital password comprises the following steps:
firstly, the 1 st digit of the access control password, namely the mark number, is generated.
It can be understood that different access control passwords can be set with different valid time periods so as to meet the requirements of different users (such as visitors and community owners). For example, the valid period that the access control password can be set may include: 0-6 points, 6-12 points, 12-18 points, 18-0 points (i.e., 24 points). In other words, the access control password may be valid only within a corresponding valid time period, and the access control password may be invalid beyond the valid time period. Accordingly, there must be a starting time corresponding to different valid periods, for example, the starting times corresponding to the valid periods 0-6, 6-12, 12-18 and 18-0 are: 0 point, 6 points, 12 points and 18 points.
Therefore, the access control passwords in different valid time periods can be distinguished according to different starting times. Specifically, this embodiment sets up 1 st digit in the 6 bit entrance guard's password is entrance guard's mark number, also passes through the mark number comes the sign the valid period that entrance guard's password belongs to. Wherein, the numerical value of the flag number can be predefined as different numerical values. For example, the flag number values corresponding to the starting time 0, 6, 12 and 18 may be set as: 0. 1, 2 and 3. The number of the entrance guard code marks corresponding to the starting time 0 point is 0, the number of the entrance guard code marks corresponding to the starting time 6 point is 1, the number of the entrance guard code marks corresponding to the starting time 12 point is 2, and the number of the entrance guard code marks corresponding to the starting time 18 point is 3. Therefore, when the access control password is generated, the 1 st digit of the access control password can be generated according to the starting time of the valid time period of the access control password.
And secondly, generating the last 5 digits of the access control password.
In order to improve the security of the access control password, the access control passwords available to different community users are different as much as possible, the access control passwords in different effective time periods are different, and the last 5 digits of the access control password can be set to be generated after the effective time period begins. For example, in this embodiment, the generation rule of 5 digits after the access control password may be set as: and generating the last 5 digits of the available access control password in the valid time period from the starting time of the valid time period to within 3 minutes after the starting time. For example, if the valid period is 0-6 o 'clock, 6-12 o' clock, 12-18 o 'clock, 18-0 o' clock, the generation rule of the last 5 digits of the access password is: generating the last 5 digits of the available access control password within 0-6 points at 0-0 point and 3 points; generating the last 5 digits of the available access control password in 6-12 points at 6-6 points and 3 points; generating the last 5 digits of the available access control password in 12-18 points at 12-12 points and 3 points; and generating the last 5 digits of the available access control password in the 18-0 point at 18 points to 18 points and 3 points.
In this embodiment, the last 5 digits of the access control password may be generated with reference to community parameters. Specifically, the method can comprise the following steps:
1) and acquiring the community number, the entrance guard serial number and the timestamp of the current time.
The community number can refer to a unique digital ID of a community, and the data type of the unique digital ID can be 4 bytes int type data; the access control serial number can be the equipment serial number of the corresponding access control equipment 2, and the data type can be 4 bytes int type data; the timestamp of the current time may be a timestamp of the access control password generated, and the data type of the timestamp may be 4-byte int-type data.
2) And respectively converting the acquired community number, the access control serial number and the timestamp into data in a first format. The first format is any one of a 2-system data format, an 8-system data format and a 16-system data format.
3) And combining the data in the first format to generate first data.
The data type of the first data is the int-type data of 10 bytes, that is: 4 bytes of community number data +2 bytes of entrance guard serial number data +4 bytes of timestamp data. For example, if the community number is 100, the entrance guard serial number is 10, and the timestamp is 1612713601, that is, 2021-02-0800: 00: 01; the generated 10 bytes of the first data may be 640000000a00810e2060 after the step of generating the first data, and the data format of the first data is a 16-system data format.
4) And carrying out XOR processing on the first data to generate second data.
For example, if the 10-byte 16-ary first data generated after the data conversion processing is 640000000a00810e2060, the 10-byte 16-ary first data is converted into 8-byte 16-ary second data after the exclusive-or processing: 64000a008b0ea16 e.
5) And performing DES encryption processing on the second data to generate third data.
The des (data Encryption standard) refers to a packet symmetric Encryption algorithm widely used in the prior art. The second data is encrypted by the DES encryption algorithm, so that the second data can be prevented from being leaked and violently cracked. According to the above example, if the second data is 8-byte, 16-system data 64000a008b0ea16e, after the DES encryption process, the generated third data may be: 5cd182c420bb5cb 7. It should be noted that the DES encryption process does not change the data type, and the third data is still 8 bytes and 16 systems data.
6) And carrying out format conversion on the third data to generate fourth data in a second format, wherein the second format is a long type 10-system data format.
It can be understood that the data, whether 2, 8 or 16, is only suitable for computer storage, operation and processing, and is not suitable for memorizing as an access password, and the data that can be understood and memorized by an ordinary user is usually only 10. Therefore, in this embodiment, the third data after the DES encryption process needs to be further converted into a data format, so as to convert the third data in the first format into fourth data in a second format that is convenient for understanding and memorizing. Wherein, the second format is preferably 10-system data. Specifically, the step of converting the format of the third data to generate fourth data in the second format may include: and converting the third data from 16-system data into long-type 10-system data, namely the fourth data. For example, if the third data is the aforementioned 5cd182c420bb5cb7, the third data is transformed into data, and the generated fourth data is: 6688270700496247991.
7) and carrying out division operation on the fourth data and obtaining the remainder of 5 digits of the division operation.
As can be seen from the above example, the fourth data in 10-ary system, which is obtained by data conversion, is a long string of numbers, such as 6688270700496247991. The fourth data has too many digits and is not suitable for direct memory, so that the fourth data cannot be directly used as the last 5 digits of the access control password. Therefore, in this embodiment, after the fourth data is generated, the available data with a smaller data length and a smaller number of bits can be obtained by dividing the fourth data by a division operation to obtain the remainder of the fourth data, and the remainder can be used as the last 5-bit number of the access password. For example, when the fourth data is 6688270700496247991, the operation of dividing the fourth data by 100000 to obtain a remainder 47991 with 5 bits can be selected according to the number of bits of the fourth data. The remainder 47991 of the 5 digits is simple and easy to remember, and is suitable for being used as the last 5 digits of an alternative access control password.
And finally, forming the 6-digit entrance guard password according to the 1 st digit and the last 5 digits of the generated entrance guard password.
It should be added that, as can be seen from the above process, the numbers of the marks of the access control passwords at the same starting time are necessarily the same, that is, the 1 st digit of the access control password is necessarily the same. Since the timestamps within 3 minutes are different, the number of the time marks is the same, and the last 5 digits generated by using different timestamps within 3 minutes are different inevitably. Therefore, the access control passwords in the same effective time period can be screened out through the same mark number to form a password library, the password library is the geometry of the available access control passwords in the same effective time period, and the last 5 digits of the access control passwords in the library are different from each other. Thus, a plurality of password libraries corresponding to different starting times can be constructed for subsequent verification of the access control password.
And step S103, determining a password library which is stored in the access control equipment 2 and corresponds to the access control equipment according to the number of the marks.
As can be seen from the foregoing, a plurality of password banks are stored in the access control device 2, the numbers of the marks of the access control passwords in the same password bank are the same, and the access control passwords with different numbers of marks belong to different password banks. Therefore, after the mark number of the access control password is obtained through inquiry, the password library corresponding to the mark number can be obtained through screening from the password library according to the mark number, so that the operation amount and the waiting time of access control password verification are reduced when the password comparison is subsequently carried out.
And step S104, comparing whether a password matched with the access control password exists in the password library.
As described above, after the corresponding password library is obtained by screening, the access control password can be verified. It should be noted that, since the numbers of the labels are the same, only the last 5 numbers of the access control password need to be compared. In this embodiment, the last 5 digits of the access control password may be defined as a password number. The step of comparing whether the password matched with the access control password exists in the password library specifically may include: and comparing the password number (namely the last 5 digits) of the password in the password bank with the password number of the access control password respectively, and judging whether the password with the password number consistent with the access control password exists in the password bank.
And S105, if the password exists, judging that the access control password is correct, and opening the access control equipment 2.
And S106, if the password does not exist, judging that the access control password is wrong, and not opening the access control equipment 2.
Through the steps S101-S106, the access control password verification method provided by the invention can automatically verify the identity of the user through the cooperation between the community platform 1, the access control equipment 2 and the owner terminal 3, automatically control the opening and closing of the access control equipment 2, ensure the smooth community passage and prompt the community safety and convenience.
Secondly, the invention also provides access control equipment 2.
In this embodiment, the access control device 2 includes the memory 11, the processor 12, and computer program instructions stored on the memory and executable by the processor, and when the computer program instructions are executed by the processor 12, the following steps may be implemented:
and S101, receiving an entrance guard password input by a user, wherein the entrance guard password is a digital password.
In this embodiment, be provided with a plurality of entrance guard's equipment 2 in the wisdom community, 2 accessible networks of entrance guard's equipment and 1 communication connection of community platform are used for in the user business turn over when the wisdom community is distinguished, the accessible sets up in 2 notice relevant personnel in the community of entrance guard's equipment of community access way, in order to acquire to open the authority of opening entrance guard's equipment 2, the user business turn over of being convenient for the community. It should be noted that the user described in this embodiment may be a community owner or a visitor. Generally, the access control device 2 may be provided with a password input unit 13, such as a numeric keypad and/or a touch screen. The user can enter specific information through the password input unit 13, preferably, a room number of the owner's own home or a home to be visited is input to inform the other party of the visitor's visit.
In this embodiment, when the access control device 2 receives information input by a user, the access control device 2 generates an access request according to the information input by the user, and sends the access request to the community platform 1. For example, the access request may be "request direction 808 house owner" or the like. Correspondingly, after the community platform 1 receives the access request, the room number input by the user is firstly obtained through the access request; then, inquiring a corresponding community owner account number which is registered in the community platform 1 in advance by the community owner according to the room number; then generating an access authorization application according to the access request and the community owner account; and finally, the community platform 1 is matched with a client program through installation in the owner terminal 3, and the community owner account is sent to the access authorization application to remind the community owner that the visitor visits and whether the access equipment 2 is opened to allow the visitor to enter and exit the community.
It can be understood that after the community platform 1 initiates the access authorization application to the corresponding owner account, it can further detect whether the corresponding application feedback is received within the preset time. If the application feedback is received, judging that the owner terminal 3 has received the access authorization application; if the application feedback is not received, the owner terminal 3 is judged not to receive the access authorization application. Wherein the preset time is preferably 1 minute.
In this embodiment, when the owner terminal 3 receives the access authorization application, the owner terminal 3 displays the access authorization application, and feeds back to the community platform 1 the user operation based on the access authorization application. The user operation at least comprises preset authorization operation and refusal authorization operation. For example, an operation page may be displayed, where the operation page includes an authorization button and a denial of authorization button, and a user may click the buttons to complete corresponding authorization and denial of authorization operations.
Further, when the community platform 1 receives the user operation fed back by the owner terminal 3, the community platform 1 detects whether the user operation is a preset authorization operation or a refusal authorization operation; if so, responding to the authorization operation and the authorization operation refusing to generate a corresponding access control instruction and sending the access control instruction to the access control equipment 2, so that the access control equipment 2 responds to the access control instruction to open and close the access control.
It can be understood that the entrance guard's instruction can be direct control the operating command that entrance guard's equipment 2 opened and closed also can be the entrance guard's password that waits to verify. For promoting the security of community, the preferred entrance guard's password of this embodiment, treat that the entrance guard's password is preferably digital password. That is, when the community platform 1 detects that the user operation is a preset authorization operation and a preset authorization rejection operation, the community platform 1 responds to the authorization operation and the authorization rejection operation, and sends an access password to the access control device 2. If the operation is authorized, sending a correct access control password; and if the operation is the refusal of the authorization operation, sending an incorrect entrance guard password. Therefore, the access control equipment 2 can be used for verifying the access control password and then opening or closing the access control. The generation step of the correct access control password will be described in detail later.
And S102, inquiring the number of the marks in the access control password.
As described above, in this embodiment, the access code is preferably a digital code, and the digital code may be a 6-digit number, where the 1 st digit is preferably a flag number of the access code. It can be understood that the 6-digit digital code is easy to remember and convenient for users to use. Therefore, in this embodiment, the access control password is preferably a 6-digit digital password. The generation method of the 6-digit digital password comprises the following steps:
firstly, the 1 st digit of the access control password, namely the mark number, is generated.
It can be understood that different access control passwords can be set with different valid time periods so as to meet the requirements of different users (such as visitors and community owners). For example, the valid period that the access control password can be set may include: 0-6 points, 6-12 points, 12-18 points, 18-0 points (i.e., 24 points). In other words, the access control password may be valid only within a corresponding valid time period, and the access control password may be invalid beyond the valid time period. Accordingly, there must be a starting time corresponding to different valid periods, for example, the starting times corresponding to the valid periods 0-6, 6-12, 12-18 and 18-0 are: 0 point, 6 points, 12 points and 18 points.
Therefore, the access control passwords in different valid time periods can be distinguished according to different starting times. Specifically, this embodiment sets up 1 st digit in the 6 bit entrance guard's password is entrance guard's mark number, also passes through the mark number comes the sign the valid period that entrance guard's password belongs to. Wherein, the numerical value of the flag number can be predefined as different numerical values. For example, the flag number values corresponding to the starting time 0, 6, 12 and 18 may be set as: 0. 1, 2 and 3. The number of the entrance guard code marks corresponding to the starting time 0 point is 0, the number of the entrance guard code marks corresponding to the starting time 6 point is 1, the number of the entrance guard code marks corresponding to the starting time 12 point is 2, and the number of the entrance guard code marks corresponding to the starting time 18 point is 3. Therefore, when the access control password is generated, the 1 st digit of the access control password can be generated according to the starting time of the valid time period of the access control password.
And secondly, generating the last 5 digits of the access control password.
In order to improve the security of the access control password, the access control passwords available to different community users are different as much as possible, the access control passwords in different effective time periods are different, and the last 5 digits of the access control password can be set to be generated after the effective time period begins. For example, in this embodiment, the generation rule of 5 digits after the access control password may be set as: and generating the last 5 digits of the available access control password in the valid time period from the starting time of the valid time period to within 3 minutes after the starting time. For example, if the valid period is 0-6 points, 6-12 points, 12-18 points, 18-0 points, the rule for generating the last 5 digits of the access control password is as follows: generating the last 5 digits of the available access control password within 0-6 points at 0-0 point and 3 points; generating the last 5 digits of the available access control password in 6-12 points at 6-6 points and 3 points; generating the last 5 digits of the available access control password in 12-18 points at 12-12 points and 3 points; and generating the last 5 digits of the available access control password in the 18-0 point at 18 points to 18 points and 3 points.
In this embodiment, the last 5 digits of the access control password may be generated with reference to community parameters. Specifically, the method can comprise the following steps:
1) and acquiring the community number, the entrance guard serial number and the timestamp of the current time.
The community number can refer to a unique digital ID of a community, and the data type of the unique digital ID can be 4 bytes int type data; the access control serial number can be the equipment serial number of the corresponding access control equipment 2, and the data type can be 4 bytes int type data; the timestamp of the current time may be a timestamp of the access control password when being generated, and the data type of the timestamp may be 4-byte int-type data.
2) And respectively converting the acquired community number, the access control serial number and the timestamp into data in a first format. The first format is any one of a 2-system data format, an 8-system data format and a 16-system data format.
3) And combining the data in the first format to generate first data.
The data type of the first data is the int-type data of 10 bytes, that is: 4 bytes of community number data +2 bytes of entrance guard serial number data +4 bytes of timestamp data. For example, if the community number is 100, the entrance guard serial number is 10, and the timestamp is 1612713601, that is, 2021-02-0800: 00: 01; the generated 10 bytes of the first data may be 640000000a00810e2060 after the step of generating the first data, and the data format of the first data is a 16-system data format.
4) And carrying out XOR processing on the first data to generate second data.
For example, if the 10-byte 16-ary first data generated after the data conversion processing is 640000000a00810e2060, the 10-byte 16-ary first data is converted into 8-byte 16-ary second data after the exclusive-or processing: 64000a008b0ea16 e.
5) And performing DES encryption processing on the second data to generate third data.
The des (data Encryption standard) refers to a packet symmetric Encryption algorithm widely used in the prior art. The second data is encrypted by the DES encryption algorithm, so that the second data can be prevented from being leaked and violently cracked. According to the above example, if the second data is 8-byte, 16-system data 64000a008b0ea16e, after the DES encryption process, the generated third data may be: 5cd182c420bb5cb 7. It should be noted that the DES encryption process does not change the data type, and the third data is still 8 bytes and 16 systems data.
6) And carrying out format conversion on the third data to generate fourth data in a second format, wherein the second format is a long type 10-system data format.
It can be understood that the data, whether 2, 8 or 16, is only suitable for computer storage, operation and processing, and is not suitable for memorizing as an access password, and the data that can be understood and memorized by an ordinary user is usually only 10. Therefore, in this embodiment, the third data subjected to the DES encryption process needs to be further converted into a data format, so as to convert the third data in the first format into fourth data in a second format that is convenient for understanding and memorizing. Wherein, the second format is preferably 10-system data. Specifically, the step of converting the format of the third data to generate fourth data in the second format may include: and converting the third data from 16-system data into long-type 10-system data, namely the fourth data. For example, if the third data is the aforementioned 5cd182c420bb5cb7, the third data is subjected to data conversion, and the generated fourth data is: 6688270700496247991.
7) and carrying out division operation on the fourth data and obtaining the remainder of 5 digits of the division operation.
As can be seen from the above example, the fourth data of 10 system, which is converted from data, is a long string of numbers, such as 6688270700496247991. The fourth data has too many digits and is not suitable for direct memory, so that the fourth data cannot be directly used as the last 5 digits of the access control password. Therefore, in this embodiment, after the fourth data is generated, the available data with a smaller data length and a smaller number of bits can be obtained by dividing the fourth data by a division operation to obtain the remainder of the fourth data, and the remainder can be used as the last 5-bit number of the access password. For example, when the fourth data is 6688270700496247991, the operation of dividing the fourth data by 100000 to obtain a remainder 47991 with 5 bits can be selected according to the number of bits of the fourth data. The remainder 47991 of the 5 digits is simple and easy to remember, and is suitable for being used as the last 5 digits of an alternative access control password.
And finally, forming the 6-digit entrance guard password according to the 1 st digit and the last 5 digits of the generated entrance guard password.
It should be added that, as can be seen from the above process, the numbers of the marks of the access control passwords at the same starting time are necessarily the same, that is, the 1 st digit of the access control password is necessarily the same. Since the timestamps within 3 minutes are different, the number of the time marks is the same, and the last 5 digits generated by using different timestamps within 3 minutes are different inevitably. Therefore, the access control passwords in the same valid time period can be screened out through the same mark number to form a password library, the password library is the geometry of the available access control passwords in the same valid time period, and the last 5 digits of the access control passwords in the library are different. Therefore, a plurality of password libraries corresponding to different starting times can be constructed for verifying the access control password in the follow-up process.
And step S103, determining a password library which is stored in the access control equipment 2 and corresponds to the access control equipment according to the number of the marks.
As can be seen from the foregoing, a plurality of password banks are stored in the access control device 2, the numbers of the marks of the access control passwords in the same password bank are the same, and the access control passwords with different numbers of marks belong to different password banks. Therefore, after the mark number of the access control password is obtained through inquiry, the password library corresponding to the mark number can be obtained through screening from the password library according to the mark number, so that the operation amount and the waiting time of access control password verification are reduced when the password comparison is subsequently carried out.
And step S104, comparing whether a password matched with the access control password exists in the password library.
As described above, after the corresponding password library is obtained by screening, the access control password can be verified. It should be noted that, since the numbers of the labels are the same, only the last 5 numbers of the access control password need to be compared. In this embodiment, the last 5 digits of the access control password may be defined as a password number. The step of comparing whether the password matched with the access control password exists in the password library specifically may include: and comparing the password number (namely the last 5 digits) of the password in the password bank with the password number of the access control password respectively, and judging whether the password with the password number consistent with the access control password exists in the password bank.
And S105, if the password exists, judging that the access control password is correct, and opening the access control equipment 2.
