| 发明名称 | Determining a user based on features | ||
| 摘要 | 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. | ||

| 主权项 | 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. | ||
