Self-authenticating electrocardiography and physiological sensor monitor

A self-authenticating electrocardiography and physiological sensor monitor, comprising:

• an electrode patch configured to be worn by a patient, comprising:
• an elongated strip of material;
• a pair of electrocardiographic electrodes exposed on a contact surface of each end of the elongated strip;
• a non-conductive receptacle adhered to an outward-facing surface of the elongated strip and comprising a plurality of electrical pads;
• and
• a circuit affixed on each end of the elongated strip and comprising a pair of circuit traces electrically coupled to the pair of the electrocardiographic electrodes and a pair of the electrical pads;
• and
• an electrocardiography monitor recorder having a sealed housing adapted to be removably secured into the non-conductive receptacle on the electrode patch and electronic circuitry comprised within the sealed housing, comprising:
• a microcontroller comprising a private key or precomputed digest, wherein a copy of the private key or precomputed digest is stored on the electrode patch worn by the patient, and configured to perform self-authentication with the electrode patch on which the electrocardiography monitor recorder is secured each time the monitor recorder is inserted into the electrode patch to authenticate for common entity source of the electrode patch and the electrocardiography monitor recorder by challenging the electrode patch using a code hashed with the private key or precomputed digest and by receiving a response from the electrode patch in reply to the challenge;
• electrical contacts arranged on a portion of an outer surface of the housing and configured to directly contact pads on the electrode patch when the housing is inserted onto the electrode patch, wherein the self-authentication is initiated upon the contact of the pads and the electrical contacts;
• and
• an electrocardiographic front end circuit electrically interfaced to the microcontroller to sense electrocardiographic signals via the pair of electrodes on the electrode patch when the response received by the microcontroller is positive and to continue to sense the electrocardiographic signals until the electrode patch expires.
