Abstract

An example described herein may involve receiving a temperature measurement associated with an input component, wherein the temperature measurement is received from a temperature sensor, and wherein the temperature measurement indicates a temperature of an input element of the input component; determining that the temperature of the input element satisfies a threshold temperature; and causing an infrared element to emit infrared light in association with a position of the input component. While the infrared element is emitting the infrared light, capture information associated with a user interacting with the input component may be obfuscated.

Claims

1. A device, comprising:

an input component;

an infrared element associated with the input component,

wherein the infrared element comprises;

an infrared emitter that emits infrared light, and

an infrared optic,

wherein the infrared optic is shaped to redirect the infrared light to substantially surround the input component when the infrared emitter emits the infrared light;

a temperature sensor;

one or more memories; and

one or more processors, communicatively coupled to the one or more memories, to;

receive, from the temperature sensor, a first temperature measurement associated with the input component,

wherein the first temperature measurement indicates a temperature of the input component;

determine, based on the first temperature measurement indicating that the temperature of the input component satisfies a threshold temperature, that a user interacted with the input component; and

cause the infrared element to emit the infrared light until at least one of;

a threshold time period, relative to determining that the temperature of the input component satisfies the threshold temperature, expires, or

the temperature sensor provides a second temperature measurement that indicates that the temperature of the input component does not satisfy the threshold temperature,

wherein, while the infrared element is emitting the infrared light, capture of information, associated with the user interacting with the input component, is obfuscated.

2. The device of claim 1, wherein the input component includes a keypad, and

wherein the infrared optic is embedded in a base of the keypad, and

wherein the infrared optic encompasses each input element of the keypad.

3. The device of claim 1, wherein the capture of the information is obfuscated by obfuscating the temperature of the input component.

4. The device of claim 1, wherein the device further comprises:

a temperature control element, and

wherein the one or more processors are further to;

cause the temperature control element to adjust the temperature of the input component to cause the temperature of the input component not to satisfy the threshold temperature.

5. The device of claim 1, wherein the device further comprises:

a temperature control element, and

wherein the one or more processors are further to;

cause the temperature control element to adjust the temperature of the input component to cause the temperature of the input component to satisfy the threshold temperature.

6. The device of claim 1, wherein the threshold temperature is relative to an ambient temperature that is measured by the temperature sensor or another temperature sensor that is communicatively coupled to the one or more processors.

7. The device of claim 1, wherein the infrared element is configured to emit the infrared light in a pulse pattern based on ambient lighting in a surrounding area of the input component.

8. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to;

determine that a user interacted with an input element of an input component,

the input component comprising a keypad, and

the input element being a key of the keypad;

determine, based on detecting that the user pressed the input element, a temperature of the input element,

wherein the temperature of the input element corresponds to the surface temperature of the key;

determine that the temperature of the input element is greater than an ambient temperature associated with an environment of the device; and

cause an infrared element of the device to emit infrared light until the temperature of the input component is within a range of the ambient temperature,

wherein, while the infrared element is emitting the infrared light, capture of information associated with the user interacting with the input element is obfuscated.

a kiosk device,

an automated teller machine (ATM) device, or

a point of sale (POS) device.

10. The non-transitory computer-readable medium of claim 8, wherein the user is determined to have used the input component based on at least one of:
