Embodiment Construction

[0033] The following is attached with the manual Figure 1-5 , to further elaborate on the technical solution involved in the present invention.

[0034] figure 1 and figure 2 A schematic structural diagram and a flow chart of the central electrical signal data acquisition system of this embodiment are respectively shown, specifically including the following steps:

[0035] Step S10, collecting electrocardiographic signals. In this embodiment, single-lead ECG signals are used for identification, including medical 12-lead or other portable ECG acquisition devices with different numbers of leads.

[0036] Because the existing ECG signal-based identification technology uses multiple feature points for each lead of the medical 12-lead ECG signal, the signal acquisition is relatively cumbersome, and the application range is small, so only one of them is needed in this embodiment. The ECG data of one lead can collect data of different objects and different time periods, so that...

Abstract

The invention discloses an electrocardiosignal data processing method. The electrocardiosignal data processing method comprises the following steps of (1) collecting data of electrocardiosignals; (2) carrying out preprocessing on the collected data of the electrocardiosignals, wherein baseline drift removal processing and de-noising processing are carried out on the collected electrocardiosignals; (3) decomposing the electrocardiosignals into single-cycle electrocardiosignal sets; (4) carrying out characteristic extraction, carrying out signal classification according to single-cycle electrocardiosignals after normalization and the level of similarity of curve signals, and choosing electrocardiosignals in the maximum class as a template; (5) detecting signal input, carrying out similarity comparison between the electrocardiosignals and a central database template to determine the identity. According to the single-leading electrocardiosignal data processing method, the mode of characteristic curve matching is adopted to carry out curve similarity comparative studies on electrocardiosignal sequences, and complex procedures for extracting characteristic points are avoided.

Description

【Technical field】 [0001] The invention relates to an identity identification technology, in particular to a method for using electrocardiographic signals to process data and then identify an identity. 【Background technique】 [0002] With the development of computer network and electronic technology, a new identity verification method has emerged to replace traditional passwords and passwords - biometric identification technology. Biometric identification technology refers to a technology that uses human biological characteristics or behavioral characteristics for identity authentication. [0003] Automatic identification systems based on biometric features have roughly the same working principle and working process. The first is to collect samples, which can be fingerprints, face images, etc.; the second is to perform feature extraction. According to the unique and unique features of the samples, an algorithm is used to assign a feature code to it, and the feature code is s...
