US 10,504,310 B2 · Techniques for access control using wearable devices

Abstract

Various embodiments are generally directed to techniques for using little or no electric power to monitor whether a wearable device continues to be worn by a person such that it may continue to be used to access a secured item. An apparatus may include a processor component; a storage to store an access credential; a presentation component to wirelessly transmit the access credential to an access device to enable a grant of access to a secured item; a power source; and a clasp coupled to a wearable portion to prevent removal of the wearable portion unless the clasp is operated to change state from a clasped state to an unclasped state, the clasp to cause loss of electric power from the power source to the processor component and the storage when in the unclasped state to nullify the access credential. Other embodiments are described and claimed.

Dependent claims

A wearable apparatus comprising:

a clasp operable between a clasped state and an unclasped state, the clasped state to place a switch in a first position and the unclasped state to place the switch in a second position;
a transistor comprising first, second, and third terminals, the first terminal connected in parallel with the switch and a positive terminal of a power source, the second terminal connected to a power input of a processor component, and the third terminal connected in parallel with the switch and a tamper signal input to the processor component;
a memory communicatively coupled with the processor component, the memory comprising data;
and
logic, at least a portion of the logic implemented by the processor component, the logic to:
identify a voltage change at the tamper signal input in response to operation of the clasp from the clasped state to the unclasped state;
and
alter one or more portions of the data in response to the voltage change.

5 more elements

At least one non-transitory computer-readable medium comprising a set of instructions that, in response to being executed by a processor component, cause the processor component to:

measure a voltage level of a positive terminal of a power source at a tamper input signal of a processor component when a switch is in a first position, the switch connected to a first terminal of a transistor in parallel with the positive terminal of the power source, a second terminal of the transistor connected to a power input of the processor component, and a third terminal of the transistor connected in parallel with the switch and the tamper signal input to the processor component;
determine a clasp is in a clasped state based on the voltage level measured at the tamper input signal of the processor component;
measure a reference voltage level at the tamper input signal of the processor component in response to operation of the switch into a second position;
determine the clasp is in an unclasped state based on the reference voltage level measured at the tamper input signal of the processor component;
and
altering one or more portions of data in a memory communicatively coupled with the processor component in response to determining the clasp is in the unclasped state.
