Embodiment Construction

[0029] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0030] The features used in the existing ECG signal authentication technology are mainly manual features, such as time domain features, frequency domain features and statistical features. Since the discriminative power of manual features is not high, the ECG signal authentication in the prior art has the disadvantage of low accuracy.

[0031] In an embodiment of the present invention, a semantic feature-based ECG signal authentication technical solution is proposed.

[0032] figure 1 It is a flow chart of the ECG signal authentication method of the present invention.

[0033] Such as figure 1 As shown, the method includes:

[0034] Step 101: Obtain an ECG signal to be authenticated.

[0035] Step 102: Extract the semantic features of the ECG signal to be au...

Abstract

The application discloses an authentication method and an authentication device for electrocardiographic signals. The method includes: acquiring electrocardiographic signals to be authenticated; extracting semantic features of the electrocardiographic signals based on a deep model, and performing authentication on the electrocardiographic signals based on the extracted semantic features.

Description

technical field [0001] The present invention relates to the technical field of signal processing, and more specifically, to an authentication method and authentication device for an electrocardiogram (ECG) signal. Background technique [0002] Biometric authentication is the use of each person's innate unique physiological or behavioral characteristics such as iris, fingerprints, face, voice and gait to confirm the identity of an individual. Compared with traditional authentication methods, it has great advantages but also faces huge challenges, such as fake fingers, fake faces, voice can be recorded, and so on. ECG signal authentication is the process of using ECG signal to confirm the identity of the operator. Due to its difficulty in counterfeiting, low-cost access and high discrimination, as a new biometric feature, it has gradually attracted widespread attention in the security field. [0003] Common ECG authentication involves the following steps: [0004] 1. Filter...
