Mobile phone anti-theft method based on near filed communication (NFC)

Abstract

The invention relates to the field of near filed communication (NFC), in particular to a mobile phone anti-theft method based on the NFC communication. The mobile phone anti-theft method based on the NFC communication comprises an anti-theft application program, wherein the anti-theft application program is arranged on an NFC communication mobile phone and is used for reading information of an integrated circuit (IC) card. When the anti-theft application program is switched on, the anti-theft application program recognizes the IC card and records characteristic information of the IC card. When the NFC communication mobile phone and the bound IC card are placed in short distance, the NFC communication mobile phone reads the characteristic information of the IC card at regular time, and then the read characteristic information of the IC card at regular time is compared with preset characteristic information of the IC card. The NFC communication mobile either continues to work or starts on a frequency locking interface to ask a user to input an unlocking password. If the input unlocking password is not correct, the NFC communication mobile phone starts on alarm ring tone. The mobile phone anti-theft method based on the NFC communication has the advantages of being capable of achieving an anti-theft function without additionally arrangement of any hardware, simple and fast in operation, capable of enabling a user to retrieve the mobile phone in a short time, low in cost and high in usability.

[0002] With the gradual improvement of the intelligence level of mobile phones, the value of mobile phones is also gradually increasing. However, expensive high-end mobile phones are often stolen in public places such as buses and subways. The personal information stored in the mobile phone is stolen, causing troubles in life

In order to get back the mobile phone in time, there are various anti-theft methods, such as installing an anti-theft device on the mobile phone, setting a password when starting up, positioning the mobile phone through satellites, etc. Most of the anti-theft methods and applications are based on the replacement of the mobile phone after the mobile phone is stolen. Card reminder, positioning, etc., but these methods may fail because the mobile phone system is reset, flashing, etc. Even if the positioning is successful, it is often impossible to retrieve the mobile phone due to low positioning accuracy and difficulty in tracking. The process of installing an external anti-theft device is complicated. The high cost even affects the use of the mobile phone itself
