A team of researchers at the University of California, Los Angeles (UCLA) and Stanford University has developed an encrypted, one-touch human-machine interface that can reveal physiological details about users.

The cryptographic bio-human-machine interface (CB-HMI) uses hydrogel-coated chemical sensors to collect and identify circulating molecules on the skin through perspiration, and to record heart rate and blood oxygen levels.

Said UCLA's Sam Emaminejad, "It also can encrypt the data at the point of collection by leveraging the individual's unique fingerprint as a key, so the collected data remain secure and private."

The sensors measure users' ethanol and acetaminophen concentrations.

UCLA's Shuyu Lin said the researchers used CB-HMI to develop a medication dispenser that administers "the appropriate amount of acetaminophen depending on current levels in the blood."
