Abstract

The invention relates to the technical field of biometric features identification, in particular to a pulse wave identification device and method based on power spectrum analysis. The device comprises a fingertip pulse detector, a signal processing unit, a Bluetooth transmitter module, a Bluetooth receiver module and an upper computer. The fingertip pulse wave detector comprises a pulse wave sensor and a preamplifier, wherein the pulse wave sensor is used for acquiring fingertip pulse wave. The output end of the pulse wave sensor is connected with the input end of the preamplifier. The input end of the signal processing unit is connected with the output end of the preamplifier. The signal processing unit is wirelessly communicated with the upper computer through the Bluetooth transmitter module and the Bluetooth receiver module. According to the method, pulse wave serves as a feature extraction classification object, and different objects are identified on the basis of pulse signal processing; identities of people of different features are distinguished by maximum entropy power spectrum estimation, and the pulse wave identification device and a fingerprint acquisition system can be combined to develop a comprehensive identification system.

Description

technical field [0001] The invention relates to the technical field of biological feature identification, in particular to a pulse wave identification device and method based on power spectrum analysis. Background technique [0002] With the advent of the information age, the scope of people's living space is rapidly expanding, and people's requirements for various information security are also getting higher and higher. This demand stimulates the continuous development and progress of modern biometric identification. [0003] The research on the application of identification methods based on biometric identification technology was mainly based on external features such as fingerprints and faces. However, in recent years, counterfeit fingerprints and other technologies have greatly affected people's information security. [0004] As a common physiological signal of the human body, the pulse wave contains a large amount of physiological information of various parts of the hea...
