Non-contact user identity authentication method based on RFID and convolutional neural network

Abstract

The invention discloses a non-contact user identity authentication method based on RFID and a convolutional neural network, and the method comprises the steps: simulating the unlocking of a sudoku of a mobile phone, deploying an RFID tag matrix, collecting the phase information during the movement of a hand, and achieving the identity authentication of a user through the convolutional neural network. The method comprises the following implementation steps of: 1, acquiring phase information of an action for identity authentication; 2, preprocessing the acquired phase information; 3, extracting starting point information of each action sample from the preprocessed phase information; 4, making the obtained phase information into a data set, and training the data by adopting a deep learning convolutional neural network to obtain a convolutional neural network model for authentication; 5, identifying the action of the user by using the trained model when the identity of the user is authenticated; and 6, obtaining an authentication result, and judging whether authentication succeeds or not. According to the invention, the invention employs the CNN-based convolutional neural network to extract the features in the phase, carries out the motion recognition, carries out the identity authentication, and is better in accuracy, safety and robustness.

Description

technical field [0001] The invention relates to the technical field of action recognition, in particular to a non-contact user identity authentication method based on RFID and a convolutional neural network. Background technique [0002] In recent years, wireless sensing has developed rapidly in various fields, such as activity perception, indoor positioning, smart home and behavior analysis. More and more households are deploying IoT devices. While it brings intelligence and convenience to people, security issues are often overlooked. Some IoT devices can control building access and the environment, and even monitor occupants' audio and video equipment, so authentication is critical. [0003] Traditional contact identification technology already has the problem of carrying special equipment, so the concept of non-contact identification that does not rely on identification objects to carry special equipment has gradually become the focus of research in recent years.
