Accelerometer-based biometric data

Abstract:

A user can provide input to a device in a 2-dimensional manner (such as by entering the data using a stylus or finger to apply pressure to a touchscreen) or in a 3-dimensional manner (such as by moving the device in 3-dimensional space). While the user input is being received, biometric data in the form of accelerometer data is collected. The accelerometer data indicates an amount of force applied in each of one or more directions over time. The collected accelerometer data thus provides an indication of the manner in which the device was moved, whether intentionally or unintentionally, while the user input was being received. The collected accelerometer data can be used in various manners, such as to verify the user input, as a signature of the user, as an authentication value to access a service or device, and so forth.
