Methods and apparatuses for proximity detection

A proximity detection device, comprising:

• an input configured to receive information indicative of a sequence of keystrokes captured while typing on a keyboard placed on a support structure;
• an input configured to receive, from a sensor device associated with a location and in contact with the support structure in proximity to the keyboard, information indicative of a sequence of captured vibrations of the support structure in response to the typing of the sequence of keystrokes on the keyboard;
• and
• a processor configured to
• check proximity between the person and the sensor device based on a comparison of the captured sequence of keystrokes with the captured sequence of vibrations, wherein the checking the proximity includes confirming the proximity between the person and the sensor device when a captured sequence of vibration peaks temporally corresponds to a captured sequence of keystroke pulses,
• authenticate the person as the user associated with the sensor device under a condition that the captured sequence of keystrokes pulses matches the captured sequence of vibrations peaks, and
• keep the person authenticated as long as one or more post-authentication captured sequences of vibration peaks temporally matches a corresponding one or more post-authentication sequences of keystroke pulses captured during a communication session and based on behaviometrics in the form of typing rhythm of the captured sequence of keystrokes.

A system for proximity detection, the system comprising:

• an input device comprising a keyboard placed on a support structure, wherein the input device is configured to capture a sequence of keystrokes when typing on the keyboard;
• a sensor device in contact with the support structure in proximity to the keyboard, wherein the sensor device is associated with a user and configured to capture a sequence of vibrations of the support structure in response to the typing of the sequence of keystrokes on the keyboard;
• and
• control circuitry configured to
• check proximity between the person and the sensor device based on a comparison of the captured sequence of keystrokes with the captured sequence of vibrations, wherein the checking the proximity includes confirming the proximity between the person and the sensor device when a captured sequence of vibration peaks temporally corresponds to a captured sequence of keystroke pulses,
• authenticate the person as the user associated with the sensor device under a condition that the proximity between the person and the sensor device is confirmed and based on behaviometrics in the form of typing rhythm of the captured sequence of keystrokes, and
• keep the person authenticated as long as one or more post-authentication captured sequences of vibration peaks temporally matches a corresponding one or more post-authentication sequences of keystroke pulses captured during a communication session and based behaviometrics in the form of typing rhythm of the captured sequence of keystrokes.
