ELECTROCARDIOGRAPHIC AUTHENTICATION-BASED DOOR CONTROL SYSTEM AND AUTHENTICATION METHOD THEREFOR

An authentication method for an electrocardiographic authentication-based door control system, comprising: performing feature extraction on a pre-processed electrocardiographic signal by using an autocorrelation transform algorithm, so as to acquire an electrocardiographic autocorrelation sequence; and then performing dimensionality reduction on the electrocardiographic autocorrelation sequence by means of orthogonal polynomial fitted regression, so as to generate a feature template; thereafter selecting and estimating an optimal electrocardiographic feature template so as to acquire the best threshold; and performing user identity authentication on the basis of the optimal electrocardiographic feature template and the best threshold. The authentication method has a high level of security, a high degree of recognition accuracy and less stored authentication information.
