Accessing a user equipment using a biometric sensor concurrently with an authentication pattern

An apparatus for user authentication, comprising:

• means for receiving a first input representing a fingerprint scan of a finger using a fingerprint sensor;
• while continuing to detect the finger on the fingerprint sensor, means for displaying, on a display, an authentication pattern in response to receiving the first input, wherein to display the authentication pattern, the means for displaying further configured to display sequentially or randomly each of a number of shapes for a duration of time within one or more portions of the display, wherein the means for displaying further configured to display each of the number of shapes for a different duration of time on the display;
• means for receiving a second input representing a detection of a removal of the finger from the fingerprint sensor;
• means for determining an authentication pattern characteristic of the authentication pattern in response to the detection of the removal of the finger from the fingerprint sensor;
• means for determining whether the fingerprint scan corresponds to a stored fingerprint scan and whether the authentication pattern characteristic of the authentication pattern corresponds to a stored authentication pattern characteristic;
• means for triggering an unlock state in accordance with a determination that the fingerprint scan corresponds to the stored fingerprint scan and the authentication pattern characteristic corresponds to the stored authentication pattern characteristic;
• and
• means for maintaining a locked state in accordance with a determination that the fingerprint scan does not correspond to the stored fingerprint scan or that the authentication pattern characteristic does not correspond to the stored authentication pattern characteristic.

A computer-readable storage device storing computer executable code for user authentication, comprising code for:

• receiving a first input representing a fingerprint scan of a finger using a fingerprint sensor;
• while continuing to detect the finger on the fingerprint sensor, displaying, on a display, an authentication pattern in response to receiving the first input, wherein displaying the authentication pattern includes displaying sequentially or randomly each of a number of shapes for a duration of time within one or more portions of the display, wherein each of the number of shapes is displayed for a different duration of time on the display;
• receiving a second input representing a detection of a removal of the finger from the fingerprint sensor;
• determining an authentication pattern characteristic of the authentication pattern in response to the detection of the removal of the finger from the fingerprint sensor;
• determining whether the fingerprint scan corresponds to a stored fingerprint scan and whether the authentication pattern characteristic of the authentication pattern corresponds to a stored authentication pattern characteristic;
• triggering an unlock state in accordance with a determination that the fingerprint scan corresponds to the stored fingerprint scan and the authentication pattern characteristic corresponds to the stored authentication pattern characteristic;
• and
• maintaining a locked state in accordance with a determination that the fingerprint scan does not correspond to the stored fingerprint scan or that the authentication pattern characteristic does not correspond to the stored authentication pattern characteristic.

An apparatus for user authentication, comprising:

• a display;
• a memory;
• a fingerprint sensor;
• and
• at least one processor coupled to the display, the memory, and the fingerprint sensor, wherein the at least one processor is configured to:
• receive a first input representing a fingerprint scan of a finger using the fingerprint sensor;
• while continuing to detect the finger on the fingerprint sensor, display, on the display, an authentication pattern in response to receiving the first input, wherein displaying the authentication pattern includes displaying sequentially or randomly each of a number of shapes for a duration of time within one or more portions of the display, wherein the at least one processor is further configured to display each of the number of shapes for a different duration of time on the display;
• receive a second input representing a detection of a removal of the finger from the fingerprint sensor;
• determine an authentication pattern characteristic of the authentication pattern in response to the detection of the removal of the finger from the fingerprint sensor;
• determine whether the fingerprint scan corresponds to a stored fingerprint scan and whether the authentication pattern characteristic of the authentication pattern corresponds to a stored authentication pattern characteristic;
• trigger an unlock state in accordance with a determination that the fingerprint scan corresponds to the stored fingerprint scan and the authentication pattern characteristic corresponds to the stored authentication pattern characteristic;
• and
• maintain a locked state in accordance with a determination that the fingerprint scan does not correspond to the stored fingerprint scan or that the authentication pattern characteristic does not correspond to the stored authentication pattern characteristic.
