FIG. 1 exemplarily shows the connection relationship between the verification device 15 and other devices and the components included in it with functional blocks and lines. In addition to the above components, the verification device 15 may further include an operation interface or/and a display interface, where the operation interface is, for example, a plurality of buttons, the display interface is, for example, a screen, and the operation interface and the display interface can also be implemented by a touch screen. In addition, in terms of entities, the verification device 15 can be installed independently, or can be installed in the same casing as the security host 13 or the door lock device 11. Alternatively, the verification device 15 may include a plurality of parts arranged in different areas. For example, the verification device 15 may have a part of the components and circuits installed in the same housing as the security host 13, and another part of the components and circuits and the door lock device 11 may be installed in another housing. Further, the processing controller 153 of the verification device 15 may include two processing control units, such as a central processing unit, a microcontroller, a programmable logic controller, etc., respectively, and one of them is installed in the same machine as the security host 13 Inside the casing, the other and the door lock device 11 are installed in another casing.

The verification device 15 is used to perform a verification procedure based on the identity information to be verified, and when the verification procedure passes, it controls the door lock device 11 to perform an unlocking action, and when the verification procedure fails, it controls the door lock device 11 and the external device 3 according to the security status. At least one of. Furthermore, the verification device 15 can obtain the identity information to be verified from the door lock device 11 and obtain the security status from the security host 13, and then perform the verification procedure on the identity information to be verified, and determine that the security status indicates a full monitoring state or a partial monitoring state. Then at least one of the door lock device 11 and the external device 2 is controlled accordingly.

To further describe the verification procedure executed by the verification device 15, please refer to FIG. 1 and FIG. 2. FIG. 2 is a flowchart of the verification procedure executed by the security system 1 according to an embodiment of the present invention. In step S101, the processing controller 153 of the verification device 15 obtains the identity information to be verified from the door lock device 11. In step S103, the processing controller 153 determines whether the identity information to be verified matches one of the plurality of pre-stored identity information stored in the memory 151. If not, the verification procedure has not passed. If so, in step S105, the processing controller 153 of the verification device 15 determines whether the time of receiving the identity information to be verified matches the pre-stored applicable time corresponding to the identity information to be verified. If not, the verification procedure has not passed. If yes, the verification procedure is passed. As mentioned above, when the verification procedure is passed, the verification device 15 will control the door lock device 11 to unlock; and when the verification procedure is not passed, the verification device 15 will generate a special state according to whether the security state is a full monitoring state or a partial monitoring state. The control signal to control the door lock device 11 or the external device 2. In this embodiment, the verification procedure includes a multi-stage verification. In addition to verifying the legitimacy of the identity information to be verified, it also verifies the legitimacy of the usage time (that is, the time for providing the identity information), thereby reducing the damage to the identity information to be verified. The risk of misappropriation improves the accuracy of the system in identifying legitimate users, thereby enhancing the security of the system.

Furthermore, although the above-mentioned two-factor authentication of identity information and usage time can increase system security. However, for some users, there is no specific rule for their use time, or for general users, occasional emergencies and need to enter the room temporarily. At this time, they cannot be judged by the verification of the above use time. For illegal intruders. Therefore, the present invention also proposes another verification procedure, including steps S101 and S103 described in the previous embodiment, and the verification device 15 determines that the time of receiving the identity information to be verified does not match the pre-stored applicable time corresponding to the identity information to be verified At that time, biometric verification will be carried out specially. Specifically, the verification device 15 generates a biometric input request and outputs it through the door lock device 11 to prompt the user to input biometric information. When the verification device 15 receives the biometric information from the door lock device 11, it will determine whether it matches the biometric characteristics of the user whose identity information has been previously judged to be legal to be verified in the pre-stored identity information. If so, the verification process is passed. No, the verification procedure has not passed. This means that when the biometric verification is passed, the verification procedure is passed. In this way, through more verifications, the accuracy of the system in identifying legitimate users can be improved.

As mentioned above, when the verification procedure fails, the verification device 15 will generate a special control signal to control the door lock device 11 or the external device 2 according to whether the security state is a full monitoring state or a partial monitoring state. Furthermore, when the verification procedure fails and the security status indicates a partial monitoring state, the verification device 15 can control the connected external device 3. For example, the external device 3 may refer to at least one monitor set outdoors. When the verification device 15 determines that the verification procedure has not passed and the preservation state indicates a partial monitoring state, it may control the monitor to perform shooting toward the door. Specifically, when the security status indicates the partial monitoring status, it indicates that someone is present. Therefore, the verification device 15 will maintain the locked state of the door lock device 11 and control the monitor to shoot toward the door to obtain the illegal intruder. Of the image. Furthermore, the verification device 15 can also generate a warning signal at the same time and send it to the security host 13, and the security host 13 then issues a warning or/and reports to the control center host 2 accordingly.

In addition, when the verification procedure fails and the security status indicates a fully monitored state, the verification device 15 may first control the door lock device 11 to perform an unlocking action, and then control the door lock device 11 to perform an anti-locking action when an actuation signal is obtained. In one embodiment, the verification device 15 obtains the open and closed state of the door from the door state detector 113 of the door lock device 11 after the door lock device 11 performs the unlocking action. When the opening and closing state of the door changes from open to closed, the verification device 15 generates an actuation signal. In another embodiment, after the door lock device 11 performs the unlocking action, the verification device 15 starts timing with the timer 155 to generate a timer value, and the processing controller 153 determines whether the timer value reaches a preset time value ( It can be pre-stored in the memory 151 or the internal memory of the processing controller 153). When the timing value reaches the preset time value, the verification device 15 will generate an actuation signal. The verification device 15 controls the door lock device 11 to perform an anti-lock action due to the generation of the actuation signal. Furthermore, the verification device 15 can control the outer lock assembly 111 to be in the locked state. When the outer lock assembly 111 is in the locked state, the door lock device 11 cannot be unlocked from the indoor side. Generally speaking, when the security status indicates the full monitoring status, it means that there is no one in the room. With the above mechanism, the verification device 15 can unlock when it is confirmed that there is no one in the room to induce an illegal intruder to enter the room, and lock the door from the outside when it is determined that the person has entered or should enter.

As mentioned above, the memory 151 of the verification device 15 stores the pre-stored identity information and pre-stored applicable time of one or more users. The user can set, change or delete his pre-stored identity information and pre-stored applicable time through the operation interface of the authentication device 15 or a personal device as the external device 3. The verification device 15 can provide a mechanism for reporting loss of identity information. Please refer to FIG. 1 and FIG. 3 together. FIG. 3 is a flowchart of a loss reporting mechanism executed by the security system 1 according to an embodiment of the present invention. Furthermore, the loss reporting mechanism includes a verification procedure, which is different from the verification procedure described in the previous embodiment. In order to distinguish the two, the verification procedure described in the previous embodiment can be called the first verification procedure, and this embodiment is called the second verification procedure, and the identity information to be verified in the previous embodiment can be called the first verification procedure. Identity information, and this embodiment is called the second identity information to be verified. It is particularly important to note that the above-mentioned "first" and "second" have nothing to do with the sequence of program execution or the sequence of information generation.

As shown in Figure 3, the loss reporting mechanism includes steps S201 to S207. In step S201, the verification device 15 receives a loss report request through the operating interface or the external device 3, wherein the loss report request includes second to-be-verified identity information representing the identity of the applicant. In step S203, the verification device 15 determines whether the second to-be-verified identity information passes the second verification procedure. In other words, the verification device 15 executes the second verification procedure based on the second to-be-verified identity information, wherein the further execution content of the second verification procedure will be described later. When the second verification procedure is passed, in step S205, the verification device 15 invalidates at least one of the pre-stored identity information according to the loss report request. When the second verification procedure fails, in step S207, the verification device 15 rejects the loss reporting request, for example, displaying a failure reporting screen through a display interface or a personal device.

In an embodiment with a loss reporting mechanism, the pre-stored identity information stored in the verification device 15 includes the changeable identity information and fixed identity information of multiple users. Among them, changeable identity information, as the name implies, refers to changeable identity information, such as passwords, digital data stored in cards, etc.; fixed identity information refers to user identity information that cannot be changed or difficult to change, such as face shape, fingerprints, and voiceprints. , Iris, etc. To further illustrate the second verification procedure, it may include determining whether the second identity information to be verified conforms to one of the above-mentioned pre-stored fixed identity information. If so, the second verification procedure is passed, and the verification device 15 invalidates the changeable identity information corresponding to the second verification identity information. Furthermore, the verification device 15 can delete the changeable identity information or set it to a blacklist to invalidate the changeable identity information.

In addition, the verification device 15 can also actively change the changeable identity information in the pre-stored identity information on a regular basis, and send the changed pre-stored identity information to the corresponding user's personal device. Through the above-mentioned periodic change and loss reporting mechanism, the risk of the user's changeable identity information such as passwords and cards being stolen can be reduced.

With the above-mentioned structure, the security system disclosed in this case not only verifies the identity information of the visitor, but also selectively controls the door lock device to perform special unlocking and then unlocking actions based on the security status of the security host. In this way, the security system disclosed in this case can not only passively eliminate illegal intruders, but also actively counteract illegal intruders and improve the security of the security system. In addition, with multi-stage identity verification, the security system disclosed in this case can reduce the risk of theft of identity information to be verified, improve the accuracy of the system in identifying legitimate users, and thereby enhance the security of the system.
