In other words, in addition to generating the unlocking signal, the handheld device 100 generates a verification signal by using a chaotic hash algorithm, and transmits the unlocking signal and the verification signal generated by the handheld device 100. The electronic access control device 200 receives the unlocking signal and the verification signal transmitted by the handheld device 100, and determines whether the received unlocking signal and the verification signal are correct. If yes, the electronic access control device 200 can control the electronic lock 300. When the locked state is changed to the unlocked state, the door body 800 is opened; otherwise, if "No", the user who wants to unlock the user may be an illegal intruder, so the electronic access control device 200 can be used by the image capturing device 400. The captured image is transmitted to another handheld device that is authenticated to increase home security.

For example, the handheld device 100 can include at least an unlocking unit 110, a verification unit 120, a first communication unit 130, a second communication unit 140, and a display unit 150, and the electronic access control device 200 can include at least a third communication unit 240, and a fourth The communication unit 250, the storage unit 210, the reference signal generating unit 220, and the processing unit 230. The unlocking unit 110 generates a unlocking signal by using a preset action performed by the handheld device 100, and the verification unit 120 stores the first key parameter and a chaotic hash algorithm, and the storage unit of the electronic access control device 200 stores the storage unit. The second key parameter and the corresponding or identical chaotic hash algorithm, and the first key parameter corresponds to the second key parameter. And, the verification unit 120 uses the first key parameter, the chaotic hash algorithm, and a time parameter to generate the verification signal. In other words, the verification signal generated by the verification unit 120 is related to the time parameter, that is, when the time is changed, the verification unit 120 generates different verification signals. That is to say, the verification signal is a one-time password signal corresponding to time, thereby reducing the risk of the verification signal being stolen.

In other words, after the handheld device 100 generates the unlocking signal and the verification signal, the unlocking signal and the verification can be transmitted by using the first connection unit 130 of the electrical connection unlocking unit 110 and the verification unit 120. The signal is transmitted to the third communication unit 240 of the electronic access control device 200. That is, the third communication unit 240 communicates with the first communication unit 130, so that the third communication unit 240 receives the unlock signal and the verification signal transmitted by the first communication unit 130. The first communication unit 130 of the handheld device 100 can transmit the unlocking signal and the verification signal to the third communication unit 240 of the electronic access control device 200 by using a Bluetooth wireless transmission technology. Moreover, the first communication unit 130 can integrate the unlocking signal and the verification signal into a Bluetooth signal for transmission, or can separately transmit the unlocking signal and the verification signal.

The processing unit 230 determines whether the verification signal is correct or not by comparing or matching the reference signal and the received verification signal. If the first communication unit 130 integrates the unlocking signal and the verification signal into a Bluetooth signal, the processing unit 230 can take out the verification signal from the Bluetooth signal and then perform the determination.

On the other hand, when the verification signal is correct, the processing unit 230 compares the preset data in the storage unit 210 with the received unlock signal to determine whether the unlock signal is correct. If the unlocking signal is still correct, the processing unit 230 controls the electronic lock 300 to switch from the locked state. The door body 800 is opened by changing to the unlocked state. On the other hand, if one or both of the unlocking signal or the verification signal is an error, the processing unit 230 may transmit the image captured by the image capturing device 400 to the fourth communication unit 250 for transmission to another handheld device that passes the verification. . The other handheld device that is verified can be, for example, the handheld device 100 whose data is pre-recorded in the electronic access control device 200. In addition, when the verification signal is an error, the processing unit 230 may not perform the comparison of the preset data and the unlock signal. Moreover, if the verification signal is correct and the unlocking signal is an error, the processing unit 230 may send an unlocking error signal to the handheld device 100 to be unlocked, so that the handheld device 100 performs the unlocking action again. In addition, when the verification signal is wrong and the unlocking signal is correct, the processing unit 230 can transmit a reminder signal to the other handheld device that passes the verification through the fourth communication unit 250, thereby reminding the user to replace the unlocking signal.

When the fourth communication unit 250 receives the image captured by the image capturing device 400, the image is transmitted to the second communication unit of the other handheld device 100 that is verified to communicate with the fourth communication unit 250. 140.
