Abstract
A system associated with predicting authentication of a device user based on a joint features representation related to an echo-signature associated with a device is disclosed. The system performs operations that include emitting acoustic signals in response to a request for processing of a profile associated with the device. The system receives a set of echo acoustic signals that are tailored based on reflection of the acoustic signals from unique contours of one or more depth portions associated with the user relative to a discrete epoch. One or one or more region segments associated with the echo acoustic signals are extracted in order to train a classification model. A classification model is generated based on the one or more region segments as extracted. A joint features representation based on the classification model is generated. A vector-based classification model is used in the prediction of the joint features representation. The system determines whether the joint features representation is associated with the echo-signature based on the prediction of the joint features representation.A corresponding method and computer-readable device are also disclosed.
