HP Auth is a trademark of MIS for the technology that combines fingerprint authorization with Enhanced PPG technology as described in US Patent 10, 076, 920

E-PPG is a trademark of MIS for the technology that optically senses a unique cardiac/pulmonary signature and the subcutaneous/dermal spectral profile of an individual—seamlessly integrated into a fingerprint sensor. The technology also implements adaptive reference algorithm to compensate for drift caused by physiological changes. The same sensors are used to detect spoof attacks.

MIS is in the Process of developing a non-functioning prototype whose sole purpose is to give a sense of commitment and history.

This card prototype will demonstrate how a credit card transaction can be authorized using HPAuth.  A functioning credit card with tap and pay (Visa payWave™, MasterCard Tap & Go™ and Interac Flash™) will be used to interact with a payment terminal via NFC.  The card will be physically but not electrically mated with a circuit that holds the fingerprint sensor, Enhanced PGG sensor, and a microcontroller.

For prototype purposes the circuit board will have an NFC jammer which will be deactivated when the verification process passes.  Essentially it will provide the same functional requirement.

An existing commercial fingerprint device will be repurposed for the fingerprint sensor & logic of the prototype. Seeing that these devices have a simple binary output (usually a motor or a solenoid), this output can be sensed by the microcontroller.  

The circuit board will have 3 LED’s to indicate positive verification,  One yellow LED will indicate positive fingerprint authentication, the second yellow LED will indicate a positive Enhanced PPG authentication.  The third green LED will indicate that the transaction is authorized. Similar to the LED’s a piezoelectric speaker will produce the corresponding sounds.

This commerical FOB prototype is the equivalent to the card prototype. The pushbutton on the fob will be functionally replaced by a relay that is activated when both fingerprint and Enhanced PPG are authenticated.
