This paper addresses the problem of dealing with privacy management of confidential data stored by enterprises and other organisations. The paper describes an innovative solution based on an adaptive privacy management system. In this system (arbitrarily complex) data structures are retrieved from standard data repositories, in such a way that parts of these data are obfuscated and associated with privacy policies. Data structures containing confidential data are "First class" objects that can be sent to other parties. Entities that try to access their content can be different from those entities that retrieve these objects. In particular, a Privacy Management Service decides what is visible at a given time for each specific request for content.
