How is a computer looking at the applicant data, including their faces, more insidious than humans looking at it? In either case the company could claim they were totally not paying attention to skin color.
You should check out the history of IQ testing particularly in the US. On paper, it seemed to be a perfectly objective way to determine an individual's intelligence. But correlating the data, it was later shown to disadvantage blacks and that is why IQ testing for jobs is now illegal.
Again, how would this prevent the company from just looking at the applicants with their eyes and discriminating against the ones they don't want?
