[ To this end, the communication unit 410 may support at least one of a wired communication method and a wireless communication method.

The alarm message generating unit 420 generates an alarm message at the request of the anti-theft device 300 or the first portable device 100. According to the embodiment, the alarm message may include at least one of the theft occurrence information indicating the stolen state of the first portable device 100, and the location information of the anti-theft device 300. [

Then, the alarm message generator 420 searches the user information database 430 to select an object to which the alarm message is to be transmitted. For example, assume that the first portable terminal and the second portable terminal are registered in the user information database 430 as a digital device owned by the user. Since the alarm message generation request signal received through the communication unit 410 is received from the first portable device 100 or the anti-theft device 300, the alarm message generation unit 420 generates a second portable The device 200 can be selected.

If the first portable device 100, the second portable device, and the third portable device (not shown) are registered as a digital device possessed by the user, the alert message generator 420 generates an alert message The second portable device 200 and the third portable device can be selected. When an object to which an alarm message is to be transmitted is selected, an alarm message is transmitted to the selected objects.

6 is a flowchart illustrating an operation method of the antitheft system 1 according to an embodiment.

Prior to the description, it is assumed that the first portable device 100 and the second portable device 200 are registered in the server 400 as a digital device possessed by the user.

First, the anti-theft device 300 performs pairing with the first portable device 100 and the second portable device 200 (S610). According to one embodiment, step S610 includes performing automatic pairing when the anti-theft device 300 is contacted with the first portable device 100. [ According to another embodiment, the step S610 may include receiving a pairing execution command from one of the first portable device 100, the second portable device 200 and the anti-theft device 300, And performing a pairing based on the received data.

When the pairing is completed, a password necessary for releasing the theft prevention mode is set and stored in the theft prevention device 300 (S625). The step S625 may include setting the password by adjusting at least one of the rotation direction, the rotation angle, and the rotation number of the input unit 340 of the anti-theft device 300, that is, the knob.

Also, in the first portable device 100, a password necessary for releasing the theft prevention mode is set and stored (S615). According to one embodiment, step S615 may include setting a password by combining at least one of numbers, characters, and special characters. According to another embodiment, step S615 may include inputting a touch pattern to set a password. The password set in step S615 is transmitted to the theft prevention device 300 (S620).

Also, in the second portable device 200, a password necessary for releasing the theft prevention mode is set and stored (S630). According to one embodiment, step S630 may include setting a password by combining at least one of numbers, letters, and special characters. According to another embodiment, step S630 may include inputting a touch pattern to set a password. The password set in step S630 may be the same as or different from the password set in step S615. The password set in step S630 is transmitted to the theft prevention device 300 (S635).

After the password setting is completed in at least one of the first portable device 100, the second portable device 200 and the antitheft device 300, the antitheft device 300, based on the antitheft mode execution command, Theft prevention mode is executed (S640). For example, in step S640, the anti-theft mode execution command may have been input through the input unit 340 of the anti-theft device 300. [ Specifically, it may be input using the push function of the knob. The anti-theft mode execution command input through the input unit 340 may be transmitted to the first portable device 100. [ As another example, in step S640, the anti-theft mode execution command may be input through the first portable device 200 or the second portable device 200 and may be received from the first portable device 100 or the second portable device 200 .

When the anti-theft mode is executed, the anti-theft device 300 detects the surroundings of the anti-theft device 300 and / or the first portable device 100 (S645). For example, the illuminance around the anti-theft device 300, the movement of the anti-theft device 300, the movement of the first portable device 100, the state of contact between the anti-theft device 300 and the first portable device 100 And the like. The degree of illumination change among the illustrated surrounding environments, the movement of the anti-theft device 300 and / or the first portable device 100, the contact state between the anti-theft device 300 and the first portable device 100, 310 may be sensed by a sensor.

Thereafter, the anti-theft device 300 generates an interrupt signal based on the detection result (S650). For example, as compared with before the antitheft mode was executed, when the illuminance around the anti-theft device 300 changed, the anti-theft device 300 moved, or the anti-theft device 300 moved to the first portable device 100), an interrupt signal is generated.

Thereafter, the anti-theft device 300 transmits an interrupt signal to the first portable device 100 (S655). The interrupt signal may be transmitted to the first portable device 100 according to a wired communication method or a wireless communication method.

6, the first portable device 100 detects an electrical connection state between the first portable device 100 and the external power source when the anti-theft mode is executed, and when the first connection state changes, And generates an interrupt signal. For example, when the cable connecting the first portable device 100 and the external power source is disconnected, the first portable device 100 generates an interrupt signal. The interrupt signal generated in the first portable device 100 may be transmitted to the anti-theft device 300.

On the other hand, after transmitting the interrupt signal to the first portable device 100, the anti-theft device 300 outputs an alarm signal based on the interrupt signal (S660). According to the embodiment, the alarm signal can be output in various ways. For example, the alarm signal may be output as sound and / or light. The type in which the alarm signal is output from the anti-theft device 300 may vary depending on the type of output means provided in the anti-theft device 300. [

The first portable device 100 also outputs an alarm signal based on the interrupt signal (S670). According to the embodiment, the alarm signal can be output in various ways. For example, the alarm signal may be output as vibration, sound, light, or a combination thereof. The manner in which the alarm signal is output in the first portable device 100 may vary depending on the type of the output means provided in the first portable device 100. [ For example, when the first portable device 100 includes a speaker, the alarm signal may be output as an alarm sound through the speaker. If the first portable device 100 includes a light emitting element, the alarm signal may be output in such a manner as to blink the light emitting element.

After outputting the alarm signal, the anti-theft device 300 or the first portable device 100 transmits an alarm message generation request signal to the server 400 (S665, S675). The alarm message creation request signal may include at least one of the information of the anti-theft device 300, the location information of the anti-theft device 300, and the information of the first portable device 100.

The server 400 receiving the alarm message generation request signal generates an alarm message (S680). The alarm message may include at least one of the theft occurrence information indicating the stolen information of the first portable device 100 and the location information of the anti-theft device 300.

Thereafter, the server 400 searches the user information database 430 and selects an object to which the alert message is to be transmitted (S685). That is, the second portable device 200 is selected as an object to which the alarm message is to be transmitted.

Thereafter, the server 400 transmits an alarm message to the selected second portable device 200 (S690).

The second portable device 200 outputs the received alarm message (S695). The alarm message can be output in various ways. For example, the alert message may be output as vibration, sound, light, text, image, moving image, or a combination thereof. The format of outputting the alarm message may vary depending on the output means provided in the second portable device 200.

On the other hand, in a state in which the first portable device 100 and / or the anti-theft device 300 are outputting an alarm signal, the user can operate the first portable device 100, the second portable device 200 and the anti- 300) (S700, S710, S715). The step S710 may include inputting a password by adjusting at least one of a rotation direction, a rotation angle, and a rotation number of the knob included in the input unit 340. [ When the password is inputted through the first portable device 100 or the second portable device 200, the inputted password is transmitted to the theft prevention device 300 (S705, S720).

Thereafter, the anti-theft device 300 determines the validity of the password input through at least one of the first portable device 100, the second portable device 200, and the anti-theft device 300 (S725). If it is determined that the input password is not identical to the previously stored password, the step S725 may include determining that the input information is not valid, Is determined to be valid.

If it is determined that the inputted password is valid, the theft prevention apparatus 300 releases the theft prevention mode (S730).

Some of the steps shown in FIG. 6 may be selectively performed. For example, only the steps S615 to S620, S625 to S625, or S630 to S635 may be performed only in the steps S615 to S620, S625, and S630 to S635.

The configuration and operation of the anti-theft system according to the embodiment have been described above with reference to Figs. 1 to 6. Fig. In Figs. 1 to 6, the case where the anti-theft device 300 includes a magnet as an adhesive member has been described as an example.

According to another embodiment, the anti-theft device may include a suction plate as an adhesive member. The attracting plate may be disposed on one side of the anti-theft device. In this case, the user can adjust the attraction force by rotating the anti-theft device's suction plate in a clockwise direction or counter-clockwise direction while the attraction plate is in contact with the installation surface (for example, with the first portable device in tabular contact. 7 and 8 will be referred to for a more detailed description.

7 is a cross-sectional view of an anti-theft device 300 'equipped with a suction plate 303, which is a sectional view showing the unfastened state. 8 is a cross-sectional view of an anti-theft device 300 'equipped with a suction plate 303, which is a sectional view showing a locked state.

The lower case 301 has a cylindrical shape. For example, it may be cylindrical or polygonal. The upper surface of the lower case 301 is an open surface, and the lower surface of the lower case 301 is a closed surface. An upper case 302 is disposed on the upper surface of the lower case 301.

Holes are formed in the center of the lower surface of the lower case 301. A screw groove is formed in the inner peripheral surface of the hole. A screw thread formed on the outer circumferential surface of the attracting plate engaging member 304 is engaged with a thread groove formed on the inner circumferential surface of the hole.

On the lower surface of the lower case 301, there is formed a concave portion 301a rising in a certain region with the hole as a center and facing the upper surface. A sucking plate 303 is disposed in the concave space formed by the concave portion 301a.

A printed circuit board (not shown) is disposed in a space formed inside the lower case 301 and the upper case 302. The components constituting the anti-theft device 300A may be disposed on the printed circuit board. For example, at least one of the components 310, 320, 330, 340, 350, 360, 370 as shown in FIG.
