DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] A SIP user anti-theft device, such as Figure 1 , Figure 2As shown, it includes a box body 1, a computer host 100 is fixedly placed in the box body 1, and a plurality of wiring ports 21 are arranged on the computer host 100, and the wiring ports 21 include multiple interfaces such as an audio line interface, a video line interface, a network cable interface, and a power line interface. An air inlet 2 and an air outlet 3 are sequentially arranged on the box body 1, and a filter screen 4 is fixedly installed in the air inlet 2 and the air outlet 3 respectively, a suction fan 8 is fixedly installed in the air inlet 2, and a hair dryer 9 is fixedly installed in the air outlet 3. An operation hole 5 is arranged on one side of the box body 1 and a blocking cover 6 is provided in cooperation. One end of the blocking cover 6 is hinged on the box body 1, and the operation hole 5 and the air outlet 3 are located on the same side. The cover 6 closes the operation hole 5, and a through groove 7 is provided on the other side of the box body 1, and the through groove 7 is located on the same side as the air inlet 2. The feature is that: a first baffle 10 is slidably installed in the box body 1 corresponding to the air inlet 2 and the through groove 7, and the first baffle 10 can close the air inlet 2, and one end of the cross tube 11 is fixedly connected to the first baffle 10, and the other end of the cross tube 11 is in airtight sliding contact with the through groove 7, and the other end of the cross tube 11 is always installed in the through groove 7 in airtight sliding contact, and a second baffle 12 is slidably installed in the box body 1 corresponding to the air outlet 3, and the second baffle 12 can close the air outlet 3, and the first baffle 10 and the first baffle 12 are in airtight sliding contact with the second baffle 12. The two baffles 12 are both equipped with a nut 13 through a connecting block, and the inner thread of the nut 13 cooperates with the same screw rod 14 to be installed. The two nuts 13 are symmetrically distributed on the left and right, and the threads at both ends of the screw rod 14 are rotated in opposite directions. The nut 13 can only move left and right on the screw rod 14. One end of the screw rod 14 is rotatably installed on the inner wall of the box body 1 through a bearing, and the other end of the screw rod 14 is fixedly connected to the output shaft of the motor 15. The output shaft of the motor 15 is coaxially arranged with the screw rod 14. The motor 15 is fixedly installed in the box body 1, and a controller 16 is fixedly installed in the box body 1. The controller 16 is electrically connected to the motor 15. A fingerprint recognition module 17 is fixedly installed, and the fingerprint recognition module 17 is electrically connected to the controller 16. A battery 19 is fixedly installed in the box body 1. The motor 15, the controller 16, and the fingerprint recognition module 17 are all connected to the battery 19 through a circuit. An adapter 18 is fixedly installed on the corresponding wiring port 21 on the first baffle 10. The adapter 18 is divided into multiple adapters such as an audio adapter, a video adapter, a network cable adapter, and a power adapter. The network cable adapter connecting the adapter 18 to the computer host is a straight-plug plug without a lock, so that it can be plugged in and out smoothly, and the adapter 18 can be plugged in and matched with the corresponding wiring port 21. The present invention has a simple structure and an ingenious design. It can not only protect the computer host 100 from fire and theft through the box body 1, but also disconnect the wiring port 21 from the adapter 18 when the computer host 100 is no longer in use to prevent hackers from invading, thereby achieving higher security. In addition, when the first baffle 10 seals the air inlet 2 and the second baffle 12 seals the air outlet 3, the computer host 100 is separated from the external environment, thereby preventing the spread of fire and protecting customer property. At the same time, it can avoid moisture and dust accumulation caused by long-term idleness of the computer host, thereby meeting actual needs and being suitable for promotion.When using the present invention, first insert various wires into the corresponding ports on the left side of the adapter 18. When using the computer host 100, the user performs identification and authentication through the fingerprint recognition module 17. After the fingerprint authentication is successful, the fingerprint recognition module 17 transmits a signal to the controller 16, and the controller 16 controls the motor 15 to operate, so that the motor 15 drives the screw rod 14 to rotate forward, thereby causing the two screw nuts 13 to move toward each other. The screw nuts 13 move through the connecting block to drive the first baffle 10 and the second baffle 12 to move toward each other, until the first baffle 10 no longer seals the air inlet 2, the second baffle 12 no longer seals the air outlet 3, the adapter 18 is inserted into the corresponding wiring port 21, and then the cover 6 is opened, and the power button of the computer host 100 is pressed, and the computer host 100 can be started and used. During the movement of the first baffle 10, the cross tube 11 is always in airtight sliding contact with the through groove 7 to prevent the unfiltered gas from directly entering the box body 1; during the use of the computer host 100 , power on the suction fan 8 and the hair dryer 9 to make them run, and the outside air can be sucked into the box 1 through the air inlet 2 by the suction fan 8 to dissipate heat for the computer host 100, and then sent out from the air outlet 3 by the hair dryer 9. The filter 4 arranged in the air inlet 2 and the air outlet 3 can filter out external impurities and dust; when the computer host 100 is turned off, the user performs fingerprint recognition authentication through the fingerprint recognition module 17 again. After the fingerprint authentication is successful, the fingerprint recognition module 17 transmits a signal to the controller 16, and the controller 16 controls the motor 15 to run, so that the motor 15 drives the screw rod 14 to rotate in the opposite direction, and then the two screw nuts 13 move back to back. The screw nuts 13 move through the connecting block to drive the first baffle 10 and the second baffle 12 to move back to back, until the first baffle 10 seals the air inlet 2, the second baffle 12 seals the air outlet 3, and the adapter 18 is disconnected from the corresponding wiring port 21. In this state, the computer host 100 has no possibility of being hacked.

[0023] Specifically, if Figure 1 As shown, in this embodiment, the first baffle plate 10 and the second baffle plate 12 are provided with a plurality of reserved holes, and the slide bars 20 are respectively slidably installed in the reserved holes, one end of the slide bar 20 is fixedly installed on the corresponding inner wall of the box body 1, and the other end of the slide bar 20 is respectively fixedly installed with the limit plate 22. Under the guidance of the slide bar 20, the first baffle plate 10 and the second baffle plate 12 can only slide to the left and right along the corresponding slide bar 20, and the setting of the limit plate 22 can prevent the first baffle plate 10 and the second baffle plate 12 from sliding off the corresponding slide bar 20. When the first baffle plate 10 and the second baffle plate 12 move away from each other, the air inlet 2 and the air outlet 3 can be sealed, and the adapter 18 can be disconnected from the corresponding wiring port 21; when the first baffle plate 10 and the second baffle plate 12 move toward each other, the air inlet 2 and the air outlet 3 can be released from being sealed, and the adapter 18 can be connected to the corresponding wiring port 21 again.

[0024] Specifically, Figure 1 and Figure 2As shown, the connecting block described in this embodiment includes an upper connecting block 30 and a lower connecting block 31, and the upper connecting block 30 and the lower connecting block 31 are slidably connected together. A dovetail slot 32 is provided on the upper connecting block 30, and a dovetail slider 33 is fixedly installed in the corresponding dovetail slot 32 on the lower connecting block 31. The dovetail slider 33 is slidably installed in the dovetail slot 32. The upper connecting block 30 and the lower connecting block 31 can only move relative to each other left and right, and the two connecting blocks are symmetrically distributed left and right; the upper connecting block 30 is fixedly installed on the corresponding nut 13, and the lower connecting block 31 is fixedly installed on the first baffle 10 or the second baffle 12; the gear 34 is rotatably installed on the lower connecting block 31, and the outer periphery of the gear 34 is respectively meshed with a first rack 35 and a second rack 36, and a push plate 38 is fixedly installed on the first rack 35, and the push plate 38 is installed on the corresponding lower connecting block through a first spring rod 37 On the block 31, the push plate 38 is fixedly connected to the movable end of the first spring rod 37, and the fixed end of the first spring rod 37 is fixedly connected to the lower connecting block 31. The box body 1 is provided with a driving mechanism that can push the two push plates 38 to move when a fire occurs. The second rack 36 is installed on the corresponding lower connecting block 31 through the second spring rod 49, one end of the second rack 36 is fixedly connected to the movable end of the second spring rod 49, and the fixed end of the second spring rod 49 is fixedly connected to the lower connecting block 31. A slot 39 is provided on the upper connecting block 30 corresponding to the second rack 36, and the second rack 36 is plugged into the corresponding slot 39. Reset springs 26 are respectively provided on the slide rods 20, and the reset springs 26 are sleeved on the corresponding slide rods 20. One end of the reset spring 26 is fixedly connected to the corresponding slide rod 20, and the other end of the reset spring 26 is fixedly connected to the first baffle 10 or the second baffle 12.When a fire occurs, the driving mechanism will push the two push plates 38 to move oppositely, and the push plates 38 will drive the corresponding first rack 35 to move outward, so that the corresponding gear 34 rotates and the first spring rod 37 is compressed. The gear 34 rotates and drives the corresponding second rack 36 to move downward until the second rack 36 is completely moved out of the slot 39 and the first spring rod 37 is compressed to the shortest. At this time, when the driving mechanism continues to push the push plates 38 to move outward, it will drive the lower connecting block 31 to move outward together, thereby driving the first baffle 10 and the second baffle 12 to move outward until the air inlet 2 and the air outlet 3 are sealed, so that the computer host 100 is separated from the outside world, and the fire is prevented from spreading from the inside of the box 1 to the outside or from the outside to the inside of the box 1. In addition, when the first baffle 10 and the second baffle 12 move, the return spring 26 is stretched and the second baffle 12 is compressed. The top side of the rack 36 maintains a sliding contact with the bottom side of the upper connecting block 30, and the adapter 18 is separated from the corresponding wiring port 21, so that when a fire occurs, under the action of the driving mechanism, the adapter 18 on the first baffle 10 is automatically separated from the wiring port 21, and the computer host 100 is isolated from the external environment; when the external temperature of the box body 1 or the internal temperature of the box body 1 decreases, the push plate 38 loses the thrust of the driving mechanism, and the first baffle 10 and the second baffle 12 are automatically reset under the action of the corresponding reset spring 26, and at the same time, the lower connecting block 31 is automatically reset, the first rack 35 is automatically reset under the action of the first spring rod 37, and the second rack 36 is automatically reset under the action of the second spring rod 49, and is reinserted into the corresponding slot 39, thereby limiting the relative movement of the lower connecting block 31 and the corresponding upper connecting block 30.

[0025] Further, such as Figure 1As shown, the driving mechanism described in this embodiment includes a vertical cylinder 40. Except for the side walls on the left and right sides of the box body 1, the other side walls are provided with cavities 41 and are connected to each other. The vertical cylinder 40 is fixedly installed on the box body 1 and is connected to the cavity 41 through the air hole on the box body 1. The cavity 41 is filled with gas that is easy to expand when heated. The push plates 38 on both sides of the vertical cylinder 40 are connected to the horizontal cylinder 42 respectively. The vertical cylinder 40 is provided with a through hole 46 corresponding to the horizontal cylinder 42. The vertical cylinder 40 is connected to the horizontal cylinder 42 through the through hole 46. The transverse cylinders 42 on both sides are symmetrically distributed, and pistons 43 are respectively installed in the transverse cylinders 42 in an airtight sliding manner. Push rods 44 are respectively fixedly installed on the pistons 43. The push rods 44 are connected to the corresponding transverse cylinders 42 through springs 45. One end of the spring 45 is fixedly connected to the corresponding push rod 44, and the other end of the spring 45 is fixedly connected to the inner wall of the corresponding transverse cylinder 42. The outer end of the push rod 44 passes through the corresponding transverse cylinder 42 and extends to the outside, and the outer end of the push rod 44 can be in contact with the corresponding push plate 38. When a fire occurs outside or inside the box 1 and the ambient temperature rises, the gas in the cavity 41 expands due to the heat and increases in volume, causing the piston 43 to be pushed outward, thereby pushing the piston 43 to move outward. The movement of the piston 43 drives the push rod 44 to move outward, and the spring 45 is compressed. When the push rod 44 abuts against the push plate 38, the push rod 44 can push the push plate 38 to move; when the ambient temperature drops to normal temperature, the gas in the cavity 41 recovers and shrinks in volume, the piston 43 loses its thrust, and the push rod 44 and the piston 43 automatically reset under the action of the spring 45.

[0026] Furthermore, as shown in the figure, the nut 13 of the present embodiment is respectively fixed with a slider 50, and a slide groove 51 is provided on the inner wall of the box body 1 corresponding to the slider 50, and the slider 50 is slidably connected with the corresponding slide groove 51. The slider 50 can only slide left and right in the slide groove 51, and under the restriction of the slider 50 and the slide groove 51, the nut 13 cannot rotate along the screw rod 14, and the nut 13 can only move left and right along the screw rod 14.

[0027] Furthermore, as shown in the figure, in this embodiment, the first baffle 10 and the second baffle 12 are respectively fixedly mounted with a sealing block 60, and the sealing block 60 can seal the air inlet 2 or the air outlet 3. The sealing block 60 can increase the sealing performance of the air inlet 2 or the air outlet 3.

[0028] Furthermore, the existing anti-fraudulent calling generally sets an address fence, but the SIP user address range needs to be manually set, and requests that are not within the range are rejected; the biggest disadvantage of the address fence technology is that it is inaccurate and untimely. Since the address range is manually specified, there must be a lag, and the user IP address cannot be accurately specified. If the fence range is too large, it will lead to the risk of fraudulent use, and if the fence is too small, it may intercept legitimate users. The computer host 100 described in this embodiment is installed with authentication client software (hereinafter referred to as client), and the authentication client software needs to run in the network where the legitimate user is locally authenticated. The authentication client software and the SIP soft switch background authentication function module (hereinafter referred to as authentication background) constitute the SIP user anti-fraudulent calling system. The method steps of the SIP user anti-fraudulent calling system are described as follows:

[0029] a) The administrator configures the user authentication method (dynamic, static, whether to authenticate the intranet, etc.) in the authentication background;

[0030] b) The client installs and runs the client on a trusted computer. The first run reads the computer's irreproducible hardware information, combines it with the account information, generates an authentication token through MD5 encryption, and transmits it to the authentication backend through the https secure channel;

[0031] c) The authentication backend records and stores the authentication token as a credential for subsequent IP update requests. Each time the authentication backend receives an update request, it needs to verify whether the token carried in the request matches the credential, and also verify the timestamp, and reject illegal requests; for legal requests, it updates the IP information in the user authentication entry;

[0032] d) After the call request initiated by the user's SIP terminal is sent to the soft switch, the soft switch first parses the signaling address and intranet address of the request initiator, accesses the authentication background through the internal interface for verification, and returns to the normal call process if the verification passes, and rejects the request if the verification fails. The present invention can fundamentally prevent the situation where SIP users on the soft switch are impersonated:

[0033] 1. The hardware information of the certified computer is non-replicable and encrypted for storage and transmission. Other computers cannot obtain certification again. This measure ensures that the network where the certified computer is located is the only trusted address;

[0034] 2. The authentication computer and the authentication background periodically shake hands to sense network changes and update address information. The background accurately authenticates the legitimate request address and updates it in quasi-real time. Compared with the "address fence" technology, it greatly improves the timeliness and accuracy of authentication;

[0035] Implementation method 1: Anti-fraud mechanism adopted by the operator's SIP open capability platform to ensure information security:

[0036] 1. During the account opening phase, the system operation and maintenance personnel open an account for the user and distribute the SIP account information to the user's technical administrator in a secure offline manner;

[0037] 2. During the installation phase, the authentication client is installed on the user's registered authentication computer. The system operation and maintenance creates an authentication entry for the user in the authentication background to accept the user's authentication. If the authentication is successful, the installation is completed. Subsequently, only the registered authentication computer can make address update requests;

[0038] 3. During the use phase, the authentication computer should remain turned on, and the authentication client should periodically shake hands with the authentication backend to confirm the address update status. Other SIP terminals in the network where the authentication computer is located can perform normal SIP communication.

[0039] Furthermore, as shown in the figure, the SIP user anti-fraud system described in this embodiment is a universal technical solution, which is not limited by the client programming language or the soft switch brand. Others can develop an authentication mechanism with similar functions based on the ideas in the solution.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
