Identity legality verification method and device and terminal equipment

Abstract

The invention provides an identity legality verification method and, an identity legality verification device and terminal equipment. The method is applied to the field of wireless network and behavior identification. The method comprises the following steps: acquiring a wireless signal reflected when a to-be-verified person to be verified passes through a preset detection area, and acquiring channel state information in the wireless signal; extracting an amplitude sequence of the channel state information, and performing principal component analysis on the amplitude sequence to obtain a principal component analysis sequence; determining whether the amplitude sequence contains personnel activity information or not according to the principal component analysis sequence, and if the channelstate information contains the personnel activity information, extracting human body activity fragments in the principal component analysis sequence; and extracting human body feature data in the human body activity segment, and performing identity legality verification of the to-be-verified person based on the human body feature data. According to the identity legality verification method and device and the terminal equipment provided by the invention, the identity legality verification precision and efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of wireless network and behavior recognition, and more specifically relates to an identity legality verification method, device and terminal equipment. Background technique [0002] In application scenarios such as health monitoring, security detection, and smart home, identity verification plays a very important role. Existing active identity verification systems generally use technologies such as fingerprint recognition and iris recognition. Although the recognition and authentication functions can be realized, the user under test needs to make specified actions, and there are problems such as expensive equipment and limited recognition locations. As a new type of sensing technology, passive sensing can enable the perceived object to be sensed as long as it enters the area to be tested without carrying any equipment or electronic tags. It is an efficient and cheap passive sensing technology. It has broad ...
