Abstract

The invention discloses an electrocardiosignal-based authentication method, apparatus and system. An embodiment of the method comprises the steps of preprocessing test electrocardiosignals; performing characteristic selection and classification on the preprocessed test electrocardiosignals by using a dictionary and a classifier, wherein the dictionary and the classifier are obtained through synchronous learning; and determining whether the test electrocardiosignals pass authentication or not based on a classification result of the test electrocardiosignals. According to the embodiment, the robust classifier is obtained through the synchronous learning dictionary and classifier, and the precision and efficiency of authentication are improved.

Description

technical field [0001] The present application relates to the technical field of signal processing, specifically to the technical field of pattern recognition, and in particular to an authentication method, device and system based on electrocardiographic signals. Background technique [0002] With the continuous development of science and technology, there are more and more methods for identity authentication through biometrics. Biometric authentication is the use of each person's unique physiological or behavioral characteristics, such as iris, fingerprints, face, voice, and gait, to confirm an individual's identity. Compared with traditional authentication methods, biometric authentication has the advantage of high authentication accuracy, but it also faces great challenges. For example, some physiological characteristics, such as fingerprints, faces or voices, can be used with fake fingers, fake faces, Pre-recorded voices and the like trick the authentication system. ...
