Palm-based ECG biometrics

We propose an experimental apparatus for ECG biometrics, that matches the usability and intrusiveness levels of traditional biometric traits like fingerprint or hand geometry centered on subject’s hand or fingers, and that require some degree of contact of proximity to the sensoring device. A hardware device was developed, comprised of a surface with integrated electrodes and signal conditioning circuitry, where the subject rests his/her hand palms, allowing the signal acquisition without the need for conductive gel nor access to more intimate parts of the body. Preliminary results show that this setup led to competitive results matching recognition rate of ECG signals acquired at the fingers.
