Under U.S. constitutional law—specifically the Fourth Amendment—there is no general "right to privacy" or reasonable expectation of privacy in public spaces for matters knowingly exposed to the public, such as your face or general appearance. The Supreme Court established this principle in Katz v.

Visual observation (including via cameras or facial recognition technology) of someone in a public place does not constitute a "search" requiring a warrant, because society does not recognize an objective expectation of privacy in one's publicly visible features.
