Embodiment Construction
[0029] like figure 1 Shown is a schematic flowchart of a method for securely transmitting data through Bluetooth technology according to an embodiment of the present invention, including a registration step 102 and a transmission step 106 . In other embodiments, a generating step 100 , a synchronizing step 104 , and / or a verifying step 108 are also optionally included. Each of them will be described in detail below.
[0030] In the generating step 100, the generation of the key can have the following three schemes:
[0031] In one embodiment, a Media Access Control (MAC) address or a random number of the detection device is directly extracted as the key.
[0032] In another embodiment, a keystream is employed. For example, if the linear feedback shift register (LFSR) method is used, taking the 7-byte (6-byte fixed and 1-byte composed of the Checksum in each sent detection data packet) password as an example, the key stream is generated as follows: Figure 2 to Figure 5 As ...

Abstract
The invention discloses a method and apparatus for securely transmitting data through a Bluetooth technology. The method comprises the following steps: a registration step, i.e., a predetermined terminal device receiving and storing device information and a secret key which are sent by a detection device; and a transmission step, i.e., utilizing the device information and the secret key, through identity verification or after encryption of detection data, the detection device transmitting the data to the terminal device. According to the method and apparatus provided by the embodiments of the invention, the detection device employs an open mode, and under the condition that personnel information is effectively protected from being leaked, through multiple means such as multiple intelligent mobile phones, personal computers, special-purpose wireless receiving gateways and the like, the data can be transmitted to a cloud end database or one or more mobile terminals.
Description
technical field [0001] The invention relates to a data transmission method and device, in particular to a method and device for securely transmitting data through bluetooth technology. Background technique [0002] Detection equipment with Bluetooth slave, such as weight scale, fat scale, body scale, blood pressure monitor, blood glucose meter, pedometer, height measuring instrument, waist scale, thermometer, heart rate meter, urine routine, oximeter, ECG Such as home health detection equipment, through bluetooth to transmit relevant data to terminal equipment (such as smart phones, personal computers, dedicated wireless gateways, etc.), and then these data can be stored and managed on the terminal equipment. [0003] At present, in order to realize such transmission, the Bluetooth slave must be docked with the terminal device once, and the data can only be communicated with this terminal device, but cannot be communicated with other terminal devices or transmitted through o...
