Person Identification Based on Hand Tremor Characteristics
This addresses biometric identification for smartphone users, but it is incremental as it applies existing methods to a new biometric measure.
The paper tackled user identification on handheld devices by analyzing hand tremor characteristics using smartphone sensors, achieving 76% accuracy on a dataset of 10,000 samples from 17 persons.
A plethora of biometric measures have been proposed in the past. In this paper we introduce a new potential biometric measure: the human tremor. We present a new method for identifying the user of a handheld device using characteristics of the hand tremor measured with a smartphone built-in inertial sensors (accelerometers and gyroscopes). The main challenge of the proposed method is related to the fact that human normal tremor is very subtle while we aim to address real-life scenarios. To properly address the issue, we have relied on weighted Fourier linear combiner for retrieving only the tremor data from the hand movement and random forest for actual recognition. We have evaluated our method on a database with 10 000 samples from 17 persons reaching an accuracy of 76%.
