Abstract

This document describes techniques and systems for authentication management through IMU and radar. The techniques and systems use inertial sensor data from an inertial measurement unit (IMU) and/or radar data to manage authentication for a computing device. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for computing-device authentication.

First claim

1 - 20 . (canceled)

21 . A method comprising:
maintaining a first level state of a user equipment, the first level state being an operating state of the user equipment that defines at least one of a first level access, power, or information state; determining, while in the first level state, a presence of a non-user based on radar data received through a radar system associated with the user equipment, the non-user being at least one of an unauthenticated person, an unknown person, or an unauthorized person; and responsive to determining the presence of the non-user, reducing the first level state of the user equipment to a low-level state, the low-level state being a low-access, a low-power, or a low-information state.

22 . The method of claim 21 , wherein the first level state is a high-level state, the high-level state being a high-access, high-power, or high-information state.

23 . The method of claim 22 , wherein:
the high-access state corresponds to an unlocked state of the user equipment and access rights to at least one of data, applications, or accounts of the user equipment; the low-access state corresponds to a locked state of the user equipment and no access rights to at least one of data, applications, or accounts of the user equipment; the high-power state corresponds to a high amount of power to one or more power-consuming components associated with the user equipment; the low-power state corresponds to a low amount of power to one or more power-consuming components associated with the user equipment; the high-information state corresponds to a high amount of information that is presented on a display associated with the user equipment; and the low-information state corresponds to a low amount of information that is presented on a display associated with the user equipment.

24 . The method of claim 21 , wherein the first level state is an intermediate-level state, the intermediate-level state being an intermediate-access, intermediate-power, or intermediate-information state, the intermediate-level state having a higher access, power, or information state than the low-level state but a lower access, power, or information state than a high-level state.

25 . The method of claim 24 , wherein:
the intermediate-access state corresponds to an unlocked state of the user equipment and limited access rights to at least one of data, applications, or accounts of the user equipment; the low-access state corresponds to a locked state of the user equipment and no access rights to at least one of data, applications, or accounts of the user equipment; the intermediate-power state corresponds to an amount of power to one or more power-consuming components associated with the user equipment sufficient to perform authentication; the low-power state corresponds to a low amount of power to one or more power-consuming components associated with the user equipment; the intermediate-information state corresponds to a limited amount of information that is presented on a display associated with the user equipment; and the low-information state corresponds to a low amount of information that is presented on a display associated with the user equipment.

26 . The method of claim 21 , further comprising:
determining, based on at least one of radar data received through the radar system associated with the user equipment or image data received through an image sensor integral with the user equipment, an identity of the non-user; and determining, responsive to determining the identity of the non-user, that the non-user does not possess authentication privileges to the user equipment for the first level state, and wherein the non-user comprises the unauthorized person.

27 . The method of claim 26 , wherein determining that the non-user does not possess authentication privileges comprises performing an authentication process, the authentication process comprising:
determining facial features of the non-user using reflected signals sensed by at least one of the radar system or the image sensor, the reflected signals including at least one of infrared, near-infrared, or radar reflections of infrared, near-infrared, or radar signals, respectively, provided by one or more emitters associated with the user equipment.

28 . The method of claim 21 , further comprising:
prior to maintaining the first level state, determining, based on radar data and by the user equipment, an intent to engage, the intent to engage indicating that a user intends to engage with the user equipment, and wherein maintaining the first level state is in response to the determination of the intent to engage.

29 . The method of claim 21 , wherein:
maintaining the first level state is based on a user interacting with the user equipment; or maintaining the first level state is based on the user recently interacting with the user equipment.

30 . The method of claim 21 , further comprising:
prior to reducing the first level state of the user equipment to the low-level state, determining, based on radar data and by the user equipment, an intent to engage, the intent to engage indicating that the non-user intends to engage with the user equipment, and wherein reducing the first level state of the user equipment to the second level state is further in response to the determination of the intent to engage by the non-user, and wherein the intent to engage is determined based on the radar data indicating that the user is reaching toward the user equipment, looking at the user equipment, or moving toward the user equipment.

31 . The method of claim 21 , wherein determining the presence of the non-user is further based on image data received through an image sensor associated with the user equipment.

32 . A user equipment comprising:
a radar system configured to provide a radar field; and a processor and a memory, coupled with the radar system, the processor configured to:
maintain a first level state of the user equipment, the first level state being an operating state of the user equipment that defines at least one of a first access, power, or information state;
determine, while in the first level state, a presence of a non-user based on radar data received through a radar system associated with the user equipment, the non-user being at least one of an unauthenticated person, an unknown person, or an unauthorized person; and
responsive to the determination of the presence of the non-user, reduce the first level state of the user equipment to a low-level state, the low-level state being a low-access, a low-power, or a low-information state.

33 . The user equipment of claim 32 , wherein the first level state is a high-level state, the high-level state being a high-access, high-power, or high-information state.

34 . The user equipment of claim 33 , wherein:
the high-access state corresponds to an unlocked state of the user equipment and access rights to at least one of data, applications, or accounts of the user equipment; the low-access state corresponds to a locked state of the user equipment and no access rights to at least one of data, applications, or accounts of the user equipment; the high-power state corresponds to a high amount of power to one or more power-consuming components associated with the user equipment; the low-power state corresponds to a low amount of power to one or more power-consuming components associated with the user equipment; the high-information state corresponds to a high amount of information that is presented on a display associated with the user equipment; and the low-information state correspo
