Embodiment Construction

[0035] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0036] The present invention specifically comprises the steps:

[0037] (1) State machine conversion: two mobile devices communicate with each other through Bluetooth connection, device A sends a packet to mobile phone B every time t1, and the sent packet will be placed in the cache (or "buffer") of device B . Device B checks the cache every time t2, t2>t1, uses its own state machine M to judge whether the mobile phone is stolen according to the cache situation. The di...

Abstract

The invention discloses an anti-theft detecting method for mobile equipment based on Bluetooth communication, comprising the following steps of: establishing Bluetooth connection between first mobile equipment and second mobile equipment; sending a data packet by the first mobile equipment to the second mobile equipment every other first time, and storing the data packet into a cache of the second mobile equipment; at the beginning, keeping the state of a state machine of the second mobile equipment as an initial state, operating a detecting progress on the second mobile equipment, and detecting the cache of the second mobile equipment every other second time; maintaining the state of the state machine in the initial state if the content of the cache of the second mobile equipment is increased; skipping the state of the state machine to the next state if the content of the cache of the second mobile equipment is not increased; detecting the cache of the second mobile equipment by the detecting progress; and if the content of the cache of the second mobile equipment is not increased after being detected N times, skipping the state of the state machine to an alarming state, and giving an alarm by the second mobile equipment. An anti-theft effect can be achieved without additional hardware.

Description

technical field [0001] The invention relates to a mobile device anti-theft detection method, in particular to a mobile device anti-theft detection method based on bluetooth communication. Background technique [0002] The current mobile smart device anti-theft technology often needs to add an additional hardware to the smart device, and the anti-theft is performed by associating the mobile smart device with the additional hardware. Once the smart device discovers that its association with the additional hardware has expired, it is considered theft, adding cost and loss of theft protection if the additional hardware fails. Contents of the invention [0003] Purpose of the invention: In view of the problems and deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a mobile device anti-theft detection method based on Bluetooth communication, which can achieve effective anti-theft effect without additional hardware. [0004] Technic...
