Embodiment Construction

[0098] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0099] Such as figure 1 Shown, a kind of method based on the Windows login authentication system of heart sound authentication, described method comprises the following steps:

[0100] (1) Utilize the earphone to extract the heart sound signal;

[0101] (2) The processing stage of the heart sound signal:

[0102] (3) An authentication method combining VQ algorithm and DTW algorithm;

[0103] (4) Log in to the system through Winform to complete the login authentication of the PC.

[0104] Firstly, the unprocessed heart sound signal is obtained through the preparation project stage, and the signal is obtained through the heart sound signal processing stage to obtain the eigenvalue, and the eigenvalue and the template eigenvalue are obtained through the heart sound signal authentication. Finally, the system judges whether it is the person ...

Abstract

The invention discloses a Windows-login-authentication-system method based on heart-sound authentication. The method includes the steps that heart-sound signals are extracted through an earphone, pre-emphasis processing is carried out, then noise passing through the heart-sound signals is removed with the wavelet de-noising method, and as heart sounds are single-cycle repeating signals, the heart-sound signals are subjected to data fusion, and the signal quality is improved. In the recognition stage, an independent wavelet extracting method based on data fusion is adopted, then a MFCC coefficient of reconstructed signals is extracted to serve as a characteristic value, an authentication method combined with the VQ algorithm and the DTW algorithm is designed, and the recognition accuracy rate is increased as far as possible. Login authentication of a PC is completed through a Winform login system.

Description

technical field [0001] The invention relates to a login authentication method, in particular to a Windows login authentication system method for heart sound authentication. Background technique [0002] With the development of science and technology, we have gradually entered the global network information age, and e-commerce and online shopping are also growing. At present, the vast majority of identity authentication technologies are still personal passwords. This security technology has low security and reliability, and is easy to be stolen by others. It cannot meet the high security and reliability requirements of some private information. In contrast, biometric authentication technology utilizes the inherent biological or behavioral characteristics of the human body, which is not easy to be counterfeited, safer and more reliable. At present, biometric authentication technology has entered our life, and the most well-known one is fingerprint recognition technology, whic...
