RANDOMIZED INPUT DEVICE HEATING

摘要

A security code input may be obfuscated from a thermal imaging device by randomly heating a random set of inputs of an input device. The security code is inputted on an input device, which communicates with a security system to grant or deny access to a user based on an entry of the security code. The input device includes a plurality of hearing elements. The input device may receive an input from the user. A random set of heating elements including one or more heating elements, are generated from the plurality of heating elements. A temperature is determined for the one or more heating elements of the random set of heating elements. The temperature is then applied to the one or more heating elements of the random set of heating elements of the input device.

主权项

1. A system for obfuscating a security code, the system comprising:
an input device including a plurality of heating elements, wherein the input device is configured to: receive an input from a user on the input device that grants access to a user based on an entry of a security code, the input device coupled to a plurality of heating elements; a memory; a processor device communicatively coupled to the input device and the memory, wherein the processor device is configured to:
measure an ambient temperature of an input device;display the input device on a graphical user interface;communicate, in response to receiving the input, a random audible tone to the user;record a temperature of the input of the user on the input device;generate, in response to receiving the input, a random set of heating elements including one or more heating elements of the plurality of heating elements;determine a temperature of a temperature range for heating one or more heating elements of the random set of heating elements based on the temperature of the input of the user, wherein the temperature range includes:
an upper threshold of the temperature range which is the temperature of the input of the user, anda lower threshold of the temperature range which is the ambient temperature of the input device; and a heating controller communicatively coupled to the input device, the memory, and the processor device, wherein the heating controller is configured to:
apply the temperature of the temperature range to each of the one or more heating elements of the random set of heating elements.
