The author introduces the concept of transformation of access rights to unify a variety of access-control mechanisms. These mechanisms have mostly been proposed independently of each other to deal with various integrity issues. Their common foundation is abstracted in a model called transform. The formalization makes it possible to investigate the minimal features required to support transform. The relation of transform to existing access-control models is then considered. It is shown that the access-matrix model transform is outside the class of systems for which safety is known to be decidable. On the other hand it is shown that transform is an instance of the decidable cases of the schematic protection model.<>
