Basically, a woman walked up to the boarding gate to get on a JetBlue flight. She looked into a camera for a few seconds and was granted access, no board pass, no ID. The JetBlue camera took a scan of her face, sent the data to DHS, who confirmed she really is who she said she is and granted access.
The terrifying part is, she never agreed to have her face scanned as part of a security check-in procedure. With anybody, not just JetBlue or DHS. So her face was scanned, analyzed, cataloged and saved with her other personal information without her permission.
I will never fly again. I would rather swim to Hawaii or walk across the continent than go through a system like that.
