1. A computing device, comprising:
- an emitter to emit an acoustic signal;
a sensor to sense the acoustic signal after the acoustic signal has passed through a portion of a user'"'"'s body;
an extractor to extract multiple features of the portion of the user'"'"'s body from the sensed acoustic signal; and
a classifier to determine, based on the extracted multiple features, whether the portion of the user'"'"'s body corresponds to a model of the portion of the user'"'"'s body used by the classifier.

Abstract
A signal may be emitted by an emitter or transducer. The signal may be sensed by a sensor, such as an accelerometer. Features of a body part or portion may be one of detected, extracted, or constructed from the sensed signal. It may be determined whether the body part or portion matches that of a user, such as an authorized user, based on the features.

8. A method, comprising:
-
emitting a vibratory signal via a transducer of a portable device; detecting features of a body part in contact with the portable device based on sensing the vibratory signal via an accelerometer; and determining whether the body part in contact with the portable device matches a body part of an authorized person by inputting the detected features into a pattern recognition model. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor, cause the processor to:
-
instruct a transducer to emit an acoustic signal; receive a sensed acoustic signal detected by an accelerometer in response to the acoustic signal after the acoustic signal has passed through a body part of an unidentified subject; construct feature vectors representing the body part of the unidentified subject from the sensed acoustic signal; and determine whether the unidentified subject matches a user based on the feature vectors. - View Dependent Claims (19, 20)
