'Rear recognition' in smart toilet can ID users

A disease-detecting smart toilet proposed in a new study by Stanford University would also come with a unique identification system.

Although ostensibly created to monitor factors such as stool and urine health, the technology packed superloo also has a built-in identification system that uses a small anal imaging scanner.

“The whole point is to provide precise, individualized health feedback, so we needed to make sure the toilet could discern between users,” said the study's author, Sanjiv “Sam” Gambhir, MD PhD, to the university's newspaper.

The researchers initially wanted to use fingerprint, but decided that they needed stronger security.

The device could be particularly appealing to individuals who are genetically predisposed to certain conditions, such as irritable bowel syndrome, prostate cancer or kidney failure.

“Our concept dates back well over 15 years,” said Gambhir, professor and chair of radiology. “When I’d bring it up, people would sort of laugh because it seemed like an interesting idea, but also a bit odd.”
