US passports, on the face page, just have your pic, birth date and gender. I just put my state in as place of birth, so no indication of hometown. That's not a huge amount of info, less than most people have in their Facebook public profiles, but I still refrain from handing over any ID to anyone I don't have to. I always stay in Marriott properties and just give my Rewards number and the credit card I used for the on-line reservation as my proof that I am who I am. I show my DL to TSA and to the rental car company, and if it's an international trip them my passport at the boarding gate or at check-in, and for Immigration. Other than that, I don't show photo ID to pretty much anyone.
