Abstract

The invention relates to a multiple-template matching identity recognition method based on an ECG (Electrocardiogram) under an electrocardiogram abnormality state, and belongs to the technical field of biological characteristic identity recognition. The ECG data of a user to be recognized is compared with the data of a registered user in a template library to obtain an identity recognition result. The key technology of the method comprises the following steps: carrying out electrocardiosignal preprocessing for eliminating noise interference; carrying out electrocardiosignal decomposition to separate an electrocardiogram waveform of each period; carrying out standardized processing for independently achieving standardization on time and amplitude scales; carrying out characteristic extraction: in the step, characteristics are extracted by wavelet transform, and clustering analysis is carried out by an ISODATA (Iterative Self-organizing Data Analysis Techniques Algorithm) so as to construct an ECC template library; and carrying out correlation analysis: in the step, correlation between ECG test data and each template is calculated, an optimal matching template is selected, and finally, an identity recognition result is obtained. The multiple-template matching identity recognition method provided by the invention utilizes the intrinsic electrocardiosignal of a human body to recognize an identity, and the ECG data under the abnormality state is considered.

Description

technical field [0001] The invention relates to a multi-template matching identity recognition method based on ECG (Electrocardiogram) in an abnormal state of electrocardiogram, which belongs to the technical field of biometric identity recognition. in individuals with cardiac arrhythmias. Background technique [0002] In modern society, identification has important applications in many fields. With the ever-increasing demand for security in today's society, the disadvantages of traditional identification methods are gradually emerging, such as easy to lose documents and easy to crack passwords. In this context, the identification technology based on biometrics gradually arouses people's widespread attention and becomes one of the research hotspots. [0003] Biometric-based identification refers to a technology that uses the physiological characteristics or behavioral characteristics of the human body to identify an individual's identity. The biological characteristics or...
