Abstract

The invention relates to the field of biological recognition, and provides an identity recognition method based on electrocardiosignals. The method comprises the following steps: S1: acquiring ECG (electrocardio) information data; S2: preprocessing information data; S3: carrying out feature extraction on the information data processed in the step S2; S4: dividing the information data processed in the S3 into a training set and a test set; S5: obtaining a training template library by the training set; and S6: comparing the similarities of the information data of the testing set and the information data of the template library, so as to determine the owner of the ECG information data. According to the method, the electrocardiosignals can be processed to realize the identity recognition, and the reliability of the recognition is strong, the antijamming capability is strong, and the recognition accuracy is high.

Description

technical field [0001] The invention relates to the field of biological identification, in particular to an identification method based on electrocardiographic signals. Background technique [0002] With the improvement of social informatization, more and more people pay attention to information security. However, the original authentication methods such as user and password are being invaded in various ways. How to obtain more secure and accurate identification has become the focus of today's technical research. Biometric technology is making this problem effectively solved. Biometric technology is a technology that uses computers and the inherent physiological characteristics of the human body to distinguish individual characteristics. [0003] The identification technology based on biometric features has been developed rapidly due to its high security, uniqueness, stability and effectiveness. The current biometric technologies mainly include fingerprint recognition, pal...
