An individual’s salinity level of salt in the body is believed to be unique. This technology passing a tiny electrical current through the body in order to analysis the salt content. The more salt in the body, the more conductive the body becomes to electricity.

An unexpected benefit of this technology is that as the electrical current passes through the body it can also carry data at a transfer rates equivalent to a 2400-baud modem. Many researchers Michigan State University, Indiana University, Purdue University) have speculated that this technology could be used to facilitate communication between devices (i.e. watches or cell phones).

Infrared Fingertip Imaging and Pattern Recognition

The technology concepts imposed for this biometric is very similar in most respects to the concepts that are used by facial thermography. With both facial thermography and infrared fingertip imagine use thermal mapping to identify patterns. The primary difference the way in which the thermal mapping is acquired. Facial thermography involves the taking of a picture with an infrared camera, while the infrared fingertip imaging and pattern recognition biometric involves the comparing the relative differences in thermal energy being observed by an infrared detector. A further contrasting comparison is that the infrared fingertip imaging and pattern recognition biometric is a contact biometric, while facial thermography is contactless (M.
