Abstract
With the rapid development of intelligent technology, people’s lives have gradually entered the era of information and intelligence. Traditional vision‐based and sensor‐based human motion detection methods have shortcomings such as high illumination requirements, difficulty in preserving privacy, and poor portability. The wireless sensor detection method based on a wireless network can overcome the shortcomings of these methods, so it has become a hot research direction. Human motion parameters are very important data. If leaked, it may cause unimaginable harm to individuals. Blockchain technology is an emerging technology in the field of information technology. Its decentralized nature, distributed storage, and data is not easy. The modification provides a feasible solution for us to realize the data upload. Combining the advantages of wireless sensing and blockchain technology, this paper proposes a method of wireless sensing collection of human motion parameters based on blockchain, and designs a human motion recognition system. The experiment found that under the experiments given in this article, the traditional accuracy rate of sensor data collection is 71.82%, and the accuracy rate of the wireless sensing collection method of human motion parameters based on the blockchain in this article has reached 95.31%, which verifies the effectiveness and superiority of the system designed in this article.

With the rapid development of artificial intelligence technology, people’s lives have gradually entered the era of informationization and intelligence
From the technical means of human motion detection, human motion detection technology is mainly divided into three categories
The advantages of this detection method include the simplicity of the equipment needed and the high precision achieved; the disadvantages are that the target person needs to wear auxiliary equipment actively, which will increase the burden on the target person to a certain extent, and it is difficult to complete the detection of motion state without cooperation
Summary
With the rapid development of artificial intelligence technology, people’s lives have gradually entered the era of informationization and intelligence. The advantages of wireless sensors, combined with the decentralization and distribution of blockchain technology, ensure the reliability of data uploading and enable designing a wireless sensor acquisition system of human motion parameters based on blockchain. The digital signature scheme designed by the SM2 encryption principle is as follows: perform key generation with the input of SM2 elliptic curve parameter parms (elliptic curve equation Ep, large prime number p, base point G, and order n of base point), randomly generate private key d ∈ 1⁄21, n − 1 and keep it secretly, and use the public-private key relationship to generate the following public key:. In this process, computing power competition is gradually replaced by equity competition. Due to the existence of a large number of point-to-point communications, it occupies a large amount of communication resources [12]
