Quite possibly, but if so this is a weird result. I was denied automatic (i.e. scan passport, go through automated face detection machine) entry into Australia (my own country) a few years ago (at the Australian end). When i asked the border security officer why it didn't admit me, she said "you have a name similar to someone on a watch list". "Oh, I didn't think my name was that common, is it a close match?" "Not that close, no".
