Embodiment
Information safety devices below in conjunction with the drawings and specific embodiments to embodiments of the invention and Bluetooth pairing method are described in further detail, but not as a limitation of the invention.
Fig. 1 is the overall structure figure of the information safety devices of embodiments of the invention.As shown in Figure 1, the information safety devices of embodiments of the invention, has the safety protection function of existing information safety means.Information safety devices comprises bluetooth module and information safety protection module, and bluetooth module contains controlled in wireless chip and the antenna of carrying out Bluetooth communication protocol, for mobile terminal radio communication, carry out the mutual of data; Information safety protection module can adopt the module or the encryption chip etc. that in any existing information safety means, configure.The information safety devices of embodiments of the invention also comprises:
Bluetooth transmission power regulation module, it is electrically connected with bluetooth module, and be configured to: in the time that bluetooth module enters Bluetooth pairing state, the transmitting power of bluetooth module is adjusted into pairing power, and after bluetooth module carries out Bluetooth pairing success, the transmitting power of bluetooth module is adjusted into normal power; This normal power is greater than this pairing power.It is that information safety devices enters can Discovery Status that information safety devices enters pairing state.
Optionally, information safety devices is KEY or encryption lock.Bluetooth pairing process can be undertaken by modes such as input pair verification codes, and this is not emphasis of the present invention, repeats no more herein.
Bluetooth transmission power regulation module of the present invention, for be able to the transmitting power of automatic adjustment information safety means in the time that bluetooth module enters Bluetooth pairing state, when opening pairing state, carry out Bluetooth pairing with low transmitting power, after the close also successful matching of other mobile devices, information safety devices recovers normal transmission power again.By information safety devices provided by the invention, accuracy and ease for use can effectively improve multiple equipment and match simultaneously time, promote user and experience, and can prevent that to a certain extent others from intercepting simultaneously, improves fail safe.
As further improvement, the information safety devices of embodiments of the invention also comprises startup module, and it is configured to: according to the Bluetooth pairing instruction that is received from user, the state of change bluetooth module is Bluetooth pairing state.Wherein, as preferred version, start module and can also comprise that the state that operates to change bluetooth module by user is the operating unit of Bluetooth pairing state.Optionally, operating unit can be the button that is arranged at the case surface of information safety devices, specifically can be positioned at front or the side and visible for user of information safety devices, user is by pressing or sliding type makes information safety devices enter pairing state, now information safety devices is can Discovery Status, or operating unit can be for being shown in the interface button on the display screen of the equipment being connected with described information safety devices.In Fig. 1, using button as example is as explanation, start module and be used for receiving button by giving an order, changed information safety means state is pairing state, and now, information safety devices is can Discovery Status.
As further improving, the information safety devices of embodiments of the invention also comprises power supply unit, and power supply unit is the battery being built in information safety devices; Or power supply unit is the power supply interface docking with external power source, for example USB or the power supply of other interfaces.Optionally, battery is lithium battery.
Improve as another kind, Bluetooth transmission power regulation module is built in information safety devices or is external in information safety devices, that is, Bluetooth transmission power regulation module can be positioned at bluetooth module inside, can be also outside functional module.
The invention also discloses a kind of Bluetooth pairing method, be applied to information safety devices described above, method comprises the following steps:
