Google storage bucket name privacy

I am trying to share media files via google storage on my website and would like to know whether or not google account name can be found out from the bucket. This will determine whether my identity will be public since credit card information must match with that of the google account. Sharing will be via embedding them onto pages, which will render their url addresses open, something like googleapis./bucketname/objectname

Anonimity is a life and death matter for what I’m trying to do, so I’d really like to know detailed information about this. I’ve heard some people say it’s vulnerable and some say its not without any evidence and I can’t find anything about it online.

Any help would be greatly appreciated
