A technique provides user authentication using a smart device (e.g., a smart phone, a tablet, etc.). The technique involves displaying, by processing circuitry of a smart device, a password prompt on a touch screen of the smart device. The password prompt includes a motion video of touch screen gestures to prompt a user of the smart device to enter a gesture password. The technique further involves receiving, by the processing circuitry, a trial gesture password entered by the user via the touch screen. The trial gesture password includes a user-entered sequence of touch screen gestures. The technique further involves performing, by the processing circuitry, multiple gesture password confirmation operations to verify that the user is able to re-enter the trial gesture password via the touch screen over time to authenticate the user to the smart device. |

1. In a smart device, a method of providing user authentication, the method comprising:
displaying, by processing circuitry of the smart device, a password prompt on a touch screen of the smart device, the password prompt including a motion video of touch screen gestures to prompt a user of the smart device to enter a gesture password; receiving, by the processing circuitry, a trial gesture password entered by the user via the touch screen, the trial gesture password including a user-entered sequence of touch screen gestures; and performing, by the processing circuitry, multiple gesture password confirmation operations to verify that the user is able to re-enter the trial gesture password via the touch screen over time to authenticate the user to the smart device;wherein displaying the password prompt on the touch screen of the smart device includes:
generating, by the processing circuitry, a random gesture password which includes a random sequence of touch screen gestures, and outputting, by the processing circuitry, the random gesture password on the touch screen, the random gesture password including the random sequence of touch screen gestures to enable the user to securely use the random sequence of touch screen gestures as the trial gesture password;wherein performing the multiple gesture password confirmation operations includes:
re-prompting the user to enter the trial gesture password via the touch screen, in response to re-prompting the user to enter the trial gesture password, acquiring user input as the user attempts to re-enter the trial gesture password via the touch screen in response to re-prompting, and based on the user input, assessing ability of the user to re-enter the trial gesture password;wherein assessing the ability of the user to re-enter the gesture password includes:
detecting a graduation event in which the user satisfies a set of gesture password entrance criteria, and converting the trial gesture password into an actual gesture password of the user in response to detection of the graduation event. |
