Additionally, when the bicycle 2 has electronic components, the controller 14 can also be integrated into the electronic components as appropriate. For example, the bicycle 2 is driven by an electric device, and the controller 14 can be integrated into the electric device. Again, the controller 14 is still mounted to the bicycle 2 by a separate device, such as on the bicycle 2 frame.

In the present embodiment, the lock 12 can lock the bicycle 2 so that the bicycle 2 cannot move, or the locking of the bicycle 2 can be released to allow the bicycle 2 to move.

The second processor 142 receives the encrypted notification signal via the second wireless communication circuit 146. The second processor 142 determines whether the encrypted notification signal is valid according to the second encrypted information. If the second processor 142 determines that the encrypted notification signal is valid, the second processor 142 generates a confirmation message. In practice, the second processor 142 can display the confirmation message via the second display and input interface 150. The user can input a confirmation input via the second display and input interface 150 according to the confirmation message, as shown in FIG. (The second display and input interface 150 is indicated by a dashed box, which includes a display screen 150a and a plurality of buttons 150b). Or the second processor 142 transmits the confirmation message to the portable device 10 via the second wireless communication circuit 146, and the first processor 102 receives the confirmation message via the first wireless communication circuit 106 via the first display and input interface 110. The confirmation message is displayed, and the user can input the confirmation input via the first display and input interface 110 according to the confirmation message, as shown in FIG. 3 (wherein the first display and input interface 110 is a display control panel, which simultaneously displays The confirmation message and a virtual keyboard can be input by the user through the virtual keyboard; then, the first processor 102 receives the confirmation input via the first display and input interface 110 and transmits the confirmation via the first wireless communication circuit 106. Input to controller 14. When the second processor 142 receives the confirmation input via the second display and input interface 150 or via the second wireless communication circuit 146, the second processor 142 determines whether the confirmation input is valid. If the second processor 142 determines that the confirmation input is valid, the second processor 142 controls the lock 12 to unlock the bicycle 2. Wherein, before the second processor 142 confirms that the confirmation input is valid, the bicycle 2 is locked by the lock 12 even if it is confirmed that the notification signal is valid. Thereby, the bicycle anti-theft system 1 ensures the communication security between the portable device 10 and the controller 14 through the validity judgment of the encrypted notification signal, and prevents the anti-theft system from being cracked; and the bicycle anti-theft system 1 also responds through the response control. The confirmation message sent by the device 14 prevents the bicycle 2 from being unintentionally unlocked. Therefore, the bicycle theft prevention system 1 can effectively prevent the bicycle 2 from being at risk of being stolen.

In addition, the first encrypted information and the second encrypted information respectively include at least a matching encryption key, which can be used for encryption and decryption of the communication, so when the controller 14 is connected to the portable device 10 by short-distance communication (for example, based on The Bluetooth protocol) allows communication between the controller 14 and the portable device 10 to be encrypted. For example, the second processor 142 of the controller 14 encrypts the confirmation message according to the second encrypted information and transmits the encrypted confirmation message to the portable device 10. The first processor 102 of the portable device 10 is configured according to the first encryption. The information decrypts the encrypted confirmation message to obtain the confirmation message; likewise, the first processor 102 of the portable device 10 encrypts the confirmation input according to the first encrypted information and transmits the encrypted confirmation input to the controller 14, and controls The second processor 142 of the processor 14 decrypts the encrypted confirmation input based on the second encrypted information to obtain the confirmation input. The content of the notification signal may include information about identification information, control authority, limited period, and the like of the portable device 10 or the controller 14.

In addition, in practice, the server 4 connected to the telecommunication network 3 can store the first encrypted information and the second encrypted information, so the portable device 10 may not have stored the first encrypted information. Instead, the first processor 102 receives the first encrypted information from the server 4 via the telecommunication network 3 via the third wireless communication circuit 108. Similarly, the controller 14 may not have stored the second encrypted information, but the second processor 142 receives the second encrypted information from the server 4 via the telecommunication network 3 via the fourth wireless communication circuit 148. Or the portable device 10 and the controller 14 originally store the first encrypted information and the second encrypted information respectively, but the portable device 10 and the controller 14 can be updated from the server 4 through the telecommunication network 3. The first encrypted information and the second encrypted information; wherein, when the controller 14 updates the second encrypted information and the portable device 10 fails to update the first encrypted information, the updated second encrypted information is in principle That is, the first encrypted information does not match, thereby generating an effect of eliminating the portable device 10 from starting the controller 14.

In addition, in practice, if the confirmation message is displayed on the controller 14 and the confirmation input is also input through the controller 14, the portable device 10 can be simplified to include only the first processor 102, the first memory. The body 104, the first wireless communication circuit 106 and the first electrical energy storage component 112 enable the portable device 10 to be substantially reduced in size while still providing a short-distance communication connection between the first processor 102 and the second processor 142. The encrypted notification signal is to the function of the controller 14. At this time, the first encrypted information can still be updated by short-distance communication between the portable device 10 and the server 4. Similarly, the controller 14 can also omit the fourth wireless communication circuit 148 and change the second encrypted information by short-distance communication with the server 4.

In practice, the confirmation message includes a confirmation string containing at least one text (eg, Chinese, Korean, etc.), letters (eg, English letters, Latin letters, etc.), numbers, or symbols (eg, an asterisk, a question mark, etc.) . As shown in FIG. 2, the confirmation string is "3847" and is displayed on the display screen 150a of the second display and input interface 150. The user inputs using the button 150b of the second display and input interface 150 as the confirmation input. If the confirmation input includes the confirmation string, the second processor 142 will determine that the confirmation input is valid. Similarly, as shown in FIG. 3, the confirmation string is "3847" and is displayed on the first display and input interface 110. The user inputs using the virtual keyboard of the first display and input interface 110 as the confirmation input. The first processor 102 transmits the acknowledgment input to the controller 14 via the first wireless communication circuit 106. If the confirmation input includes the confirmation string, the second processor 142 will determine that the confirmation input is valid.

Please refer to FIG. 4. FIG. 4 is a flow chart of a bicycle unlocking method according to the present invention. The bicycle unlocking method is used in a bicycle anti-theft system.

Receiving the encrypted notification signal, as shown in step S120; the second processor 142 determines whether the encrypted notification signal is valid according to the second encryption information, and if valid, the second processor 142 generates a confirmation message. As shown in step S130, the second processor 142 displays the confirmation message via the second display and input interface 150 or transmits the confirmation message to the portable device 10 via the second wireless communication circuit 146, as shown in step S140; The second processor 142 receives, via the second display and input interface 150, an input confirmation input by the user according to the confirmation message or via the second wireless communication circuit 14 6 When receiving the confirmation input from the portable device 10, the second processor 142 determines whether the confirmation input is valid. If it is valid, the second processor 142 controls the lock 12 to unlock the bicycle 2, as shown in step S150. Therefore, the bicycle unlocking method ensures the communication security between the portable device 10 and the controller 14 through the validity judgment of the encrypted notification signal, and prevents the anti-theft system from being cracked; and the bicycle unlocking method also responds to the control.

Whether it is valid, as shown in step S230. In practice, whether the encrypted notification signal is valid can be correctly decrypted by the encrypted notification signal, or by determining whether the decrypted notification signal content is valid. In the former, when the encrypted notification signal is correctly decrypted, the decrypted notification signal has meaningful content and format. In the latter case, although the decrypted notification signal has meaningful content and format, the content cannot make the portable device 10 have the authority to legally control the controller 14.
