Embodiment Construction

[0042] The invention proposes a technical solution for periodically generating tokens using a key (key) of a Bluetooth signal transmitter. Each bluetooth signal transmitter has its own key, and the map navigation server in the positioning service background stores the key of each bluetooth signal transmitter. The map navigation server obtains the UUID, RSSI and token information of the Bluetooth signal transmitter, and first verifies the token when performing positioning calculations. Because the aforementioned tokens change regularly, cloning the UUID to fake a location is no longer feasible.

[0043] Before introducing the embodiments of the present invention, some terms involved in this text are firstly defined.

[0044] 1. Bluetooth Low Energy (Bluetooth Low Energy, BLE): Also known as Bluetooth Low Energy, it is a personal area network technology designed and sold by the Bluetooth SIG, intended for use in healthcare, sports, beacons, security, Emerging applications in a...

Abstract

The invention relates to a method, device and computer-readable storage medium for bluetooth positioning. The method includes: receiving a universally unique identification code UUID, a signal field strength indication RSSI and a first token from a terminal device; when the first token is the same as the second token calculated by the positioning service background, sending the token to the terminal device Feedback of the positioning of the terminal device calculated by the positioning service background, and sending a feedback of refusal of positioning to the terminal device when the first token and the second token are different.

Description

technical field [0001] The present invention relates to the field of positioning, in particular to a positioning method, device and storage medium based on Bluetooth positioning. Background technique [0002] For indoor positioning, Bluetooth positioning is mainly implemented using the Bluetooth Low Energy technology BLE (Bluetooth Low Energy) of Bluetooth 4.0. At present, there is no general international standard for Bluetooth positioning technology, but it is generally based on the positioning principle of RSSI (Received Signal Strength Indication). In the existing technical solution for locating terminal devices, the UUID and RSSI values ​​corresponding to each beacon are uploaded to the map engine service for positioning calculation. The UUID is fixed for each terminal device and is visible to external devices, and is easy to be cloned. For example, if a terminal device clones the data after receiving several beacon data at a certain place, it can still upload the dat...
