Google recently admitted it had employees walking the streets in several U.S. cities asking people if they wanted to sell their facial data for $5 gift certificates. They were using this data to help improve Pixel 4's face unlock system. Now, the New York Daily News reports that Google contractors have been using some very dubious tactics to get people's facial data. According to several sources who were working for the Daily News, a contracting agency called Randstad sent teams to Atlanta with the specific intention of finding homeless people with dark skin. According to the report, the contractors often didn't say they were recording the individual's faces or that they were working for Google.

An electrocardiogram, abbreviated ECG, is a test used by doctors to record the electrical activity of patients' hearts. ECG is a painless and non-invasive procedure. Scientists have used artificial intelligence to use ECG data to predict a person's age and sex. With further advancement, scientists could help doctors determine the overall health status of a patient. The research team from the Mayo Clinic in Rochester had published a paper titled "Circulation: Arrhythmia and Electrophysiology."
