Abstract

A security and protection system is provided for a mobile communication device. When the device is turned on, upon detecting that the SIN card is invalid or is not installed or has been replaced, the system automatically locks a database of personal data of the device or limits or prohibits the use of some or all functions of the device. Further, the device may designate one or more external devices so that when a protection control unit of the device is activated, the device may only accept control instructions issued from the designated external device. Further, when the device detects a replacement SIM card is inserted, the device automatically transmits data and phone number of the replacement SIM card to the designated device to allow an original owner of the device to issue control instructions or making communication with the device.

Claims

1. A security and protection system of a mobile communication device, comprising a subscriber identity module (SIM) card identification unit and a protection control unit coupled to a mobile communication circuit, wherein:

the SIM card identification unit is connected to a master control unit of the mobile communication circuit for reading data stored in the SIM card installed in the device and making comparison with originally built SIM card data in order to make an option of shutting down the device or activating operation of the protection control unit in accordance with the result of inspection; and

the protection control unit is connected to the master control unit of the mobile communication circuit and to the SIM card identification unit, and adapted to receive data from the master control unit and instructions of the SIM card identification unit, then execute internally built control programs according to the data or command;

the protection control unit has lock functions for locking all or partial functions of the device and operates an SMS control instruction, wherein the SMS control instruction further comprises control programs;

locking device, uploading specified data, and deleting specified data.

2. The security and protection system according to claim 1, wherein the SIM card identification unit and the protection control unit product, comprising:

a logic circuit or software or firmware or a combination thereof.

3. The security and protection system according to claim 1, wherein the SIM card identification unit having an inspection function that inspects whether the SIM card is installed or SIM card is replaced or SIM card is invalid.

4. The security and protection system according to claim 3, wherein when detected the SIM card is not installed, the system activates the protection control unit to enter a protection mode.

5. The security and protection system according to claim 3, wherein when detected the SIM card is replaced or the SIM card is invalid, the system activates the protection control unit to enter a protection mode.

6. The security and protection system according to claim 5, wherein when detected the SIM card is replaced, the system automatically transmits data of the replacement SIM card to a designated device through a short message.

7. The security and protection system according to claim 1, wherein the protection control unit comprises a protection mode and a normal mode, each mode comprising three operation flows respectively associated with a function selecting status, a standby status, and an SMS control status.

8. The security and protection system according to claim 7, wherein the operation flow of the function selecting status of the protection mode comprises at least setting a function for prohibiting use of a personal database.

9. The security and protection system according to claim 7, wherein the operation flow of the function selecting status of the protection mode comprises setting a function for prohibiting use of all functions.

10. The security and protection system according to claim 7, wherein the SMS control status of the protection mode and the normal mode comprises inspection of SMS instructions for determining source of SMS control instruction and execution of a job designated by the SMS control instruction after the source is determined to be correct.

11. The security and protection system according to claim 7, wherein the protection mode comprises an unlocking function in connection with the function selecting status, whereby when cause the system to perform the predetermined setting or controlled by SMS control instruction to have partial or all functions locked, the system is allowed to resume operation of normal mode through application of the unlocking function to effect unlocking.

12. The security and protection system according to claim 1, wherein in an initial use of the device, a user is required to set up one or more designated devices for transmission of messages and wherein the protection control unit accepts only SMS control instruction from the designated device.

13. The security and protection system according to claim 1 further comprising a GPS receiving unit coupled to the mobile communication circuit, the GPS receiving unit receiving a positioning signal from a positioning satellite to be coupled to the master control unit, and subsequent sending the positioning signal via the SMS.
