A method of authenticating a health measurement taken from a medical measurement device may include establishing a network connection between a computing device and a medical measurement device. The network connection may be established via contact of a user with electrodes of the computing device and contact of the user with electrodes of the medical measurement device. While user contact is maintained with the electrodes of the computing device, the electrodes of the medical measurement device, and a biometric sensor of the computing device health measurement data of the user may be received at the computing device from the medical measurement device. Also while contact is maintained, the user may be authenticated using a measurement of the biometric sensor of the computing device. The health measurement data may be signed based on the authenticating.
