Public disclosure of private facts arises where one person reveals information which is not of public concern, and the release of which would offend a reasonable person. Unlike libel or slander, truth is not a defense for invasion of privacy. Disclosure of private facts includes publishing or widespread dissemination of little-known, private facts that are non-newsworthy, not part of public records, public proceedings, not of public interest, and would be offensive to a reasonable person if made public.
Account information of any type is private and there for not of public concern.
