A pairing method and system for wearable smart devices based on heartbeat signals

Abstract

The present invention provides a wearable smart device pairing method and system based on a heartbeat signal. The wearable smart device pairing method includes the following steps: Step S1, the wearable smart device collects the change signal after the light is absorbed by the blood, and converts it Convert it into an electrical signal to obtain the user's heartbeat data; Step S2, filter the user's heartbeat data; Step S3, calculate the heartbeat period of the filtered heartbeat data; Step S4, according to the heartbeat period and the heartbeat data within the heartbeat period The difference value yields a binary key. The present invention analyzes and processes the user's own heartbeat data, and then effectively matches the binary key with the heartbeat data, and can extract accurate heartbeat data in the process of data analysis and processing, and can achieve a good matching effect, giving the user A secure pairing and authentication method is provided, which realizes the data privacy protection of the user's wearable smart device, and has low hardware cost and is easy to implement.

Description

technical field [0001] The present invention relates to a pairing method of a wearable smart device, in particular to a pairing method of a wearable smart device based on a heartbeat signal, and to a pairing system of a wearable smart device using the pairing method of a wearable smart device based on a heartbeat signal . Background technique [0002] With the continuous advancement of the intelligent society and the continuous development of emerging smart devices, especially the explosive growth of wearable smart devices, more and more wearable smart devices appear in our daily life, which can give us For example, smart headphones can provide us with a lot of personal health-related data, allowing us to detect information related to our vital signs in real time, escorting the health of each of us, and greatly improving our quality of life. a strong guarantee. While we are using the convenience of smart devices, we may need to disconnect and reconnect frequently. When tra...

Problems solved by technology

[0003] The pairings studied at home and abroad are as follows: On smart phones, we often pair with Bluetooth, but Bluetooth pairing has the following disadvantages. First, Bluetooth pairing is very insecure. For advanced hackers, it is completely possible to pass the interference of the signal channel To continuously monitor the privacy data we want to send, which has been proved in many literatures; secondly, the number of Bluetooth matching devices is limited, intelligent matching of a device, and we need to match a lot of wearable smart devices, this Bluetooth cannot meet our needs; finally, we all know that turning on Bluetooth all the time consumes a lot of power, which is unacceptable for wearable smart devices with small battery capacity

[0004] Now there is also a way to pair multiple wearable smart devices based on gait, because when a person is walking, the gait will affect the whole body of the person, that is, the whole body will move when walking, and use acceleration to control different devices The signal between them generates a series of keys through signal processing, but this has a big problem that it can only be used when people are moving, that is to say, we cannot pair successfully when we are quiet. , which necessarily limits the scope of its work to a large extent

[0005] There are also some existing technologies that use surrounding information such as ambient light and sound to generate a series of keys. The problem with this existing technology is that due to the complex changes in the surrounding environment and the large noise, it cannot accurately Identify Security Key
