There is a notion of 'privacy', codified in Mishna Baba Batra, which is probably much older than the 2nd century. I don't think so. Jefferson uses the word 'liberty' in the Declaration to express this enlightenment ideal which was first articulated by Spinoza. For that reason, morality and the right to privacy are virtually identical in liberal thinking. Jewish law, on the other hand, knows no fundamental 'rights' or 'freedoms'.
Jewish law is built on the concept of mitzvah, or obligation.
Privacy is not a 'good' in itself, rather an instrumental value for the accomplishement of some other obligation. For example, privacy is derivative of the obligation of modesty and respect for property rights. Unlike enlightenment based systems, the individual is never 'free' from obligation in Jewish law, consequently it makes no sense to speak of 'rights'. The idea that you are entitled to hide significant aspects of your life from your neighbors or your in-laws or your community strikes me as an essentially modern idea. I see no indication of such an entitlement in the Hebrew Bible.
