Dugan's other idea sounds like something straight out of Minority Report: Taking a daily password pill, just as you would a vitamin. The pill features a small chip with a switch that uses your stomach acids to activate, creating an 18-bit, ECG-like signal inside your body. "My hands are like wires, my arms are like alligator clips," Dugan said. "When I touch my phone, my computer, my door, my car, I’m authenticated."
ATAP—which is remaining with Google when the rest of Motorola is sold to Lenovo—is working with a company called Proteus Digital Health to make these pills a reality. Proteus already has FDA approval to create an ingestible sensor, though its efforts are largely focused on using the sensor as a medical device.
