Method to use physical vibration to turn any solid surface for user authentication

  • Method for utilizing vibration analysis in user authentication
  • Not limited to touch screens; works on solid surfaces constructed of a broad range of materials

Abstract

This technology relates to systems and methods for user input and authentication using vibration analysis. In particular, this technology extends finger-input authentication beyond touch screens to any solid surface for smart access systems (e.g., access to apartments, vehicles, smart appliances, etc.). It integrates passcode, behavioral, and physiological characteristics, and surface dependency together to provide a low-cost, tangible, and enhanced security solution. It significantly differs from traditional password-based approaches, which only authenticate the password itself rather than identifying a legitimate user, as well as behavioral biometrics-based solutions which usually involve specific or expensive hardware (e.g., touch screen or fingerprint reader), and which incur privacy concerns and suffer from smudge attacks. This technology discriminates fine-grained finger inputs and supports a plurality of independent passcode secrets including, but not limited to, PIN number, lock pattern, and simple gestures by extracting unique features in the frequency domain to capture both behavioral and physiological characteristics such as contacting area, touching force, etc. It can be implemented using a low-cost vibration motor and a receiver that can be easily attached to any surface (e.g., a door panel, a desk, or an appliance). Experiments demonstrate that this technology can authenticate users with high accuracy, low false-positive rate, and robustness to various types of attacks.

Advantages

A user authentication solution with smart access capability that can work with any solid surface (such as a door, a table, or a vehicle’s window), is not limited to touch screens, and can be implemented with minimal hardware and maintenance cost.

Potential Applications

This technology extends finger-input authentication beyond touch screens to any solid surface for smart access systems (e.g., access to apartments, vehicles, smart appliances, etc.).
