Systems and methods for bluetooth authentication using communication fingerprinting

A method for a computing system, comprising:

• responsive to initiating a Bluetooth connection between a host device and a client device, determining whether a saved communications fingerprint for the client device is stored in a memory of the computing system;
• responsive to determining that the saved communications fingerprint for the client device is not stored in the memory of the computing system, generating a new communications fingerprint for the client device based on response characteristics of the client device and storing the new communications fingerprint in the memory of the computing system;
• responsive to determining that the saved communications fingerprint for the client device is stored in the memory of the computing system, comparing the response characteristics of the client device to the saved communications fingerprint;
• and
• responsive to determining that the response characteristics of the client device do not match the saved communications fingerprint, terminating the Bluetooth connection with the client device.

A computing system, comprising:

• a Bluetooth stack including an RF layer and an application layer;
• a processor communicatively coupled to the computing system;
• and
• a storage device storing instructions executable by the processor to:
• responsive to initiating a Bluetooth connection with a client device, generate a first communication fingerprint for the client device based on response characteristics of the client device.
