AI Technical Summary

Benefits of technology

This patented technology allows users' biometric data (ECG) to be analyzed without requiring any comparisons between them or even if they have similarities themselves. It uses an algorithm that compares these patterns against existing databases containing known ones to find matches quickly enough. Overall this process helps identify individuals more efficiently than just comparing their own unique pattern from previous experiences.

Problems solved by technology

The technical problem addressed by this patented technique relates to identifying individuals through an electrocardiogram (ECG) pattern alone without requiring any complicated calculations associated with comparing them against databases containing thousands of templates stored previously. This makes current techniques impracticable because they cannot identify new users quickly enough due to their small size compared to existing ones.

Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] The core of the present invention is to provide a method and system for identification based on electrocardiographic signals, so as to overcome the disadvantages in the prior art that the characteristics of heart beats to be identified need to be compared with all heart beat templates in the total template library for each identity recognition in the prior art, and then To achieve the purpose of being able to establish a large-scale identification system.

Abstract

The invention discloses an identity identification method and an identity identification system based on electrocardiosignals. The method comprises steps that, to-be-identified heart beat characteristics of electrocardiosignals of a to-be-identified user are extracted; a preset class group classifier is utilized to classify the to-be-identified heart beat characteristics, and class groups of the to-be-identified heart beat characteristics are determined; similarity between heart beat templates in a template database of the class groups of the to-be-identified heart beat characteristics and the to-be-identified heart beat characteristics is calculated, and a user corresponding to the heart beat template having the largest similarity with the to-be-identified heart beat characteristics is determined to be the to-be-identified user. As the heart beat templates in the template database of the class groups of the to-be-identified heart beat characteristics are only a part of heart beat templates in a template database of various class groups, computational complexity is low, so the method effectively solves a problem that the to-be-identified heart beat characteristics are required to compare with all heart beat templates in a total template database during identity identification, and thereby a large-scale identity identification system can be established.
