Preferably, the mobile terminal in this embodiment is a MID terminal that accesses the public network based on the wireless mode. In the related art, the hardware is used to realize the high anti-theft cost of the mobile terminal, and the use of software to implement the anti-theft of the mobile terminal has problems such as being easily cracked. In this embodiment, the anti-theft identification card is fixedly disposed in the mobile terminal, so that the anti-theft identification card cannot be easily taken out even if the mobile terminal is stolen, and the anti-theft identification card number is different from the SIM card number of the mobile terminal, so that even in theft In the case of replacing the SIM card of the mobile terminal, the original user of the mobile terminal cannot be prevented from dialing the anti-theft identification card number or making a call to the number, thereby performing effective searching and tracking, thereby solving the prior art mobile terminal anti-theft. The problem of high cost or easy to be cracked in the technology, thereby achieving effective anti-theft and loss tracking effects. Referring to FIG. 2, a block diagram of a security system in a mobile intelligent terminal according to a second embodiment of the present invention is shown. This embodiment takes an anti-theft MID terminal that accesses the public network based on the wireless mode as an example. The special feature of other intelligent terminals is that, in addition to the usual SIM card for identifying the identity, the MID terminal is also built with a special anti-theft SIM card (ie, an anti-theft identification card, referred to as an AT-SIM card), and Like a normal SIM card, an AT-SIM card can also be used as a signal identity of a MID terminal, called a second identity. The wireless receiving module of the MID terminal can receive the signal sent to the AT-SIM card, thereby turning on the anti-theft mechanism, such as audio and video recording, encoding and transmission. It should be noted that the AT-SIM card only has a receiving function and does not have the ability to transmit signals. In addition, the MID terminal system also supports the anti-theft preset function. When the direction sensor and the gravity sensor are set to sense that the X, Y, Ζ direction or gravity force speed of the MID terminal changes, the anti-theft mechanism is activated, such as alarm, sound, Video recording, encoding and transmission functions, etc. The wireless transmitting module of the MID terminal transmits the collected live information, such as recorded audio and video, to a specific server or a designated storage terminal through a wireless transmission protocol such as H.223. To transmit data, the wireless module port is mapped to the AT port, the control port, the audio port, and the video port to receive or send downlink or uplink corresponding data. The specific implementation process is as follows: (1) Booting initial 4匕 Service (Anti-theft system service), Service is mainly responsible for receiving upper layer control, complete audio and video data collection, codec call, data transmission and related device control.

(2) Sending a signal to the AT-SIM card to activate the anti-theft mode. If the user sends a signal to the AT-SIM card, such as dialing the number, the anti-theft scheme of the MID terminal of the embodiment includes: Step 1: Same as the ordinary SIM card, After the MID terminal is powered on, the AT-SIM card is in the IDLE idle state, and the Ring incoming call state is monitored. In order to ensure that the AT-SIM card can have the function of receiving signals while supporting the normal operation of the ordinary SIM card, in the MID terminal, the RF system and the call flow control for processing the AT-SIM card signal can be set independently. The work does not affect the normal operation of the normal SIM card. Of course, the RF system and call flow of the AT-SIM card can also be shared with the common SIM card process. At this time, the AT-SIM card and the SIM card RF system and call control can be integrated. Step 2: When the wireless module of the MID terminal receives the signal and judges that it is the anti-theft system signal, it proceeds to step 4 and does not enter the normal ringing, vibration or incoming call notification interface. Step 3: The MID terminal starts the recording field function, records the real-time sound and video, and records the real-time audio as a PCM (Pulse Code Modulation) code stream, and encodes it into an AMR (Adaptive Multiple Rate) format. To reduce the amount of audio data; record real-time video as a stream conforming to the 263.263 protocol format, and encode it into 3GP or ΜΡ4 format to reduce the amount of video data. To transmit data, the wireless module port is mapped to the AT port, the control port, the audio port, and the video port. The MID terminal transmits the audio and video stream from the audio and video ports of the wireless module to the designated server or terminal through the H.223 protocol. And, send the corresponding command through the AT port. Step 4: After receiving the AT port command, the server or terminal specified by the receiving side receives the audio and video data and saves it as a file. In addition to j3⁄4, when implementing MID terminal anti-theft, you can also use the preset anti-theft method.

The MID terminal is especially useful when it is in a static state, as follows: Step A: The MID terminal starts the preset anti-theft mode, for example, sets an alarm tone, enters the automatic dialing function state, etc.; and initializes the sensor, including the direction sensor and the gravity sensor, and monitors the direction sensor. SENSOR ORIENTATION and gravity sensor SENSOR ACCELEROMETER change 4匕. Step B: When the value of SENSOR ORIENTATION or SENSOR ACCELEROMETER changes and exceeds the threshold (a predetermined threshold), it is determined that the MID terminal is touched or moved. Step C: The speaker (audio player) of the MID terminal plays an alarm tone to determine whether the automatic dialing state is set. If the status value is TRUE, that is, automatic dialing is set, the RIL (Radio Interface Layer) layer is called, and the dialing preset is sent. The number command, and the signal is sent by the AT port of the wireless module. At the same time, the recording function is turned on, the real-time audio is recorded as a PCM stream, and encoded into an AMR format to reduce the amount of audio data, the real-time video is recorded as an H.263 code stream, and encoded into a 3GP or MP4 format to reduce the amount of video data. The audio and video streams are sent out by the audio and video ports of the wireless module through the H.223 protocol. And, send the corresponding command through the AT port. Step D: After receiving the AT port command, the receiving terminal (such as the set server or other terminal) receives the audio and video data and saves it as a file. In this embodiment, if the MID terminal is stolen, whether the direction of the MID terminal and the acceleration of the gravity acceleration are detected by the preset anti-theft method, the anti-theft mechanism is activated, and the automatic recording is started. Audio and video, playing 4 alarms, etc., and will be pressed by the wireless module of the MID terminal The shortened audio and video data is sent to the designated server or the designated receiving terminal. At the same time, the use of AT-SIM card also overcomes the shortcomings of data corruption, anti-theft device is easy to be cracked, etc. It can conveniently and flexibly monitor and track MID terminals, improve the timely rate of reporting, and obtain favorable crimes for criminals. Evidence helps the case handlers catch the criminals faster. Therefore, the disadvantages of the anti-theft system of the existing mobile terminal and the mobile terminal itself are overcome, and an anti-theft method capable of quickly tracking and retrieving after the MID smart terminal is lost, and being more convenient and safe when placed in the home is provided, further Improve the anti-theft and security of MID smart terminals. Referring to FIG. 3, a schematic diagram of the anti-theft function activation and operation mode of the first scenario of the embodiment of the present invention is shown. The usage scenario of this embodiment is: When the MID terminal is lost, the AT-SIM card can still be used as the signal identity of the MID terminal. At this time, the wireless receiving module of the MID terminal can receive the signal sent to the AT-SIM card, thereby opening Audio and video recording, encoding and transmission functions. In this embodiment, the MID terminal includes functions of a general smart terminal, such as a touch display screen, media playback, digital photo frame, web browsing, telephone voice, and the like. It is connected to the external network through a wireless communication module (including but not limited to WCDMA, CDMA2000, TD-SCDMA, WiMAX, and LTE, etc.). The AT-SIM card in the MID terminal is different from the ordinary SIM card. It is a dedicated SIM card. It is embedded in the smart terminal at the factory. The user cannot easily take it out, and only dials the card number under certain circumstances (such as theft). , number management, system, etc. can be jointly developed by the manufacturer and the operator. The RF system and call control of the AT-SIM card can be a stand-alone system that has the function of receiving signals, separately supporting the AT-SIM card, or an integrated system integrated with the ordinary SIM card by adding the working mode of the AT-SIM card. . The audio and video collection device of the MID terminal includes a microphone and a camera, and has the function of collecting audio and video data. In addition, a data receiving terminal is provided, including a set server and other terminals. The server is not a component of the mobile intelligent terminal, and belongs to the entire anti-theft system. The server receives and stores the audio and video data information sent by the MID terminal through the wireless communication module. The management authority of the server is the terminal manufacturer or the operator. The data management on the server can be cleaned once every two weeks or one month, and the user requests to delete it or send it to the user for saving. The user can also customize the storage terminal that receives the audio and video stream, but the terminal must conform to the real-time data transmission protocol, and receive the audio and video data of the MID terminal in the open state and sufficient storage space. Since the main feature of the anti-theft system is that it is not detected and opened, there is basically no function on the interface. Only the setting options include the function of automatically starting the anti-theft system and/or dialing the AT-SIM card after the preset anti-theft system is turned on. The function of the anti-theft system is activated. In this embodiment, the function of starting the anti-theft system when dialing the AT-SIM card is mainly used. After the MID terminal is lost, you can call the preset AT-SIM card to open the related function and start the anti-theft system. After the anti-theft system is activated, all audio and video data collection and codec calls are completed by the Service layer of the anti-theft system. The Service layer is mainly responsible for receiving upper layer control, completing audio and video data collection, codec calling, data transmission, and related device control. The anti-theft process of the MID terminal based on the above setting includes: Step S302: Dialing the AT-SIM card number, the MID terminal determines whether it is a normal voice or a request anti-theft system according to the signal type, and when determining that the AT-SIM card is received, determining to request the anti-theft system , then initialize the protocol stack and request to establish a wireless link. Step S304: determining whether the MID terminal is opening an application such as a voice call, a video call, a photograph, a camera, and the like, and if yes, returning, and prompting that the anti-theft system cannot be turned on temporarily; if not, executing step S306. Step S306: When the MID terminal does not open the application in step S304, establish a link between the dialing party and the MID terminal, and establish a data link between the MID terminal and the set data receiving end. Step S308: Start the MIC of the MID terminal and the 4 image header, record the real-time audio and video data stream, and encode it into an AMR format or an MP4 format or a 3GP format audio and video data stream, and the audio and video port of the wireless module of the MID terminal. Transfer to the set terminal or server through the H.223 protocol. Step S310: The user dialing the AT-SIM card hangs up the phone, stops, releases the protocol stack, removes the link, and the MIC (microphone) and the camera stop working. It should be noted that when the MID terminal is performing an application such as voice call, video call, photographing, camera, or insufficient power supply, the anti-theft system cannot be accessed; and when the AT-SIM card is working, the ordinary SIM card has an outgoing or incoming signal. Or action, it will prompt the network to be busy; When the AT-SIM card is working, if there are actions such as taking pictures, 3⁄4 images or recording, temporarily exit the anti-theft system. Referring to FIG. 4, a schematic diagram of the anti-theft function activation and operation mode of the scenario 2 according to the embodiment of the present invention is shown. The usage scenario of this embodiment is: the MID terminal is placed at home, and the MID terminal supports the anti-theft preset function, and when the sensor senses that the X, Y, Ζ direction or the gravitational acceleration of the MID terminal changes, the alarm, audio and video recording is started. , encoding and transmission functions. The data sent by the wireless module of the MID terminal is transmitted to a specific server or a designated storage terminal through a wireless transmission protocol such as H.223. Different from the mobile intelligent terminal in the embodiment shown in FIG. 3, the MID terminal in this embodiment is further provided with a sensor, including a direction sensor and a gravity sensor, having functions of sensing gravity, direction, temperature, pressure, etc., by judging jitter. The change of direction, etc. determines whether the MID terminal is touched or moved. The anti-theft process of the MID terminal based on the above setting includes: Step S402: Presetting the anti-theft function of the MID terminal. Including: (1) audio recording selection, when the sensor of the MID terminal detects that the position change of the mobile terminal exceeds the set threshold, automatically turns on the microphone to record the sound; (2) video recording selection, when the sensor of the MID terminal detects the mobile terminal When the position change exceeds the set threshold, the image head is automatically opened, and the video data is recorded; (3) the alarm sound is selected, and when the sensor of the MID terminal detects that the position change of the mobile terminal exceeds the set threshold, the automatic play user is pre-stored. The audio, such as the alarm sound of the police car or the alarm sound recorded by the user in advance; (4) automatic dialing selection, when the sensor of the MID terminal detects that the position change of the mobile terminal exceeds the set threshold, the telephone number is automatically dialed, and the telephone number can be Pre-set by the user, such as a mobile phone number that can be carried by the user, or a mobile phone number of another person, or an alarm phone, etc., and the pre-stored audio can be played to the receiving end, and the pre-stored audio can input information such as the home location, what happened, and the like.
