Abstract
The emergence of Information Systems brought about some problems linked to the notion of privacy. If the computerization of data was generally considered to be a progress, it was sometimes accompanied by fright, or even by fantasies nourished by Big Brother, about possibility for other people or for an instituted power to know everything about an individual. Even if notions of security and privacy are not mutually foreign, in information systems, especially concerning identification technologies, security measures pose problems for the protection of private life.
