Jogand Coulomb Fabrice, Holtzman Michael, Qawami Bahman, Barzilai Ron: Control structure for versatile content control and method using structure. Sandisk Corporation, Jogand Coulomb Fabrice, Holtzman Michael, Qawami Bahman, Barzilai Ron, HSUE James S, June 29, 2006: WO/2006/069311 (16 worldwide citation)

A tree structure stored in the storage medium provides control over what an entity can do even after gaining access. Each of the nodes of the tree specifies permissions by an entity who has gained entry through such node of the tree. Some trees have different levels, where the permission or permissi ...
