USER IDENTIFICATION WITH BIOKINEMATIC INPUT
First Claim
1. A computing device, comprising:
- a multi-touch touch sensitive display including a sensor configured to receive biokinematic input including data representing detected positions of each of a plurality of digit touches made by a corresponding plurality of digits of a user, in each of a series of successive time intervals during a defined identification gesture; and
a user identification module executed by a processor of the computing device, the user identification module being configured to receive the biokinematic input from the sensor, and further configured to compare relative positions of the plurality of digit touches and/or relative rates of change in said positions of the plurality of touches to a stored user template of verified biokinematic data for the user, and if a match is determined, to display an indication on the display that the user has been successfully identified.

Abstract
Systems and methods for user identification based on biokinematic input are disclosed herein. The system may include a multi-touch sensitive display including a sensor configured to receive biokinematic input including data representing detected positions of digit touches made by digits of a user, in each of a series of successive time intervals during a defined identification gesture. The system may further include a user identification module executed by a processor of the computing device. The user identification module may be configured to receive the biokinematic input from the sensor, and to compare relative positions of the digit touches and/or relative rates of change in said positions of the digit touches to a stored user template of verified biokinematic data for the user. If a match is determined, an indication that the user has been successfully identified may be displayed.

11. A computerized user identification method, comprising:
-
receiving user biokinematic input of an identification gesture including a plurality of digit touches made by a corresponding plurality of digits of a user, in each of a series of successive time intervals, via a multi-touch sensitive display of a computing device; comparing respective positions and/or respective rates of change in said positions of the plurality of digit touches during at least a portion of the identification gesture in the biokinematic input to a stored user template of verified biokinematic data for the user; and if a match is determined by the comparing, then displaying an indication on the display that the user has been successfully identified. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A computing device, comprising:
-
a portable multi-touch sensitive display including a sensor configured to receive biokinematic input including data representing detected positions of each of a plurality of digit touches made by a corresponding plurality of digits of a user, in each of a series of successive time intervals during a defined identification gesture; a user identification module executed by a processor of the computing device, the user identification module being configured to receive the biokinematic input from the sensor, the user identification module including; a feature extractor configured to, in a registration phase, receive a first biokinematic input from the sensor and extract user-identifying features from the first biokinematic input, wherein the first biokinematic input includes relative positions of the plurality of digit touches and/or relative rates of change in said positions of the plurality of touches; and a template generator configured to generate a user template including the user identifying features and store the user template in a data store; wherein the feature extractor is further configured to, in a user identification phase, receive a second biokinematic input from the sensor, wherein the second biokinematic input includes relative positions of the plurality of digit touches and/or relative rates of change in said positions of the plurality of touches, wherein a matching engine is configured to compare the second biokinematic input to the stored user template of verified biokinematic data for the user, and if a match is determined, to display an indication on the display that the user has been successfully identified. - View Dependent Claims (20)
