TLDR
A data processing system include a plurality of data objects which are accessible by application programs through a system level interface as discussed by the authors. Each data object has an associated user access list, and each object has at least one key indicating which applications can access that object.Abstract:
A data processing system include a plurality of data objects which are accessible by application programs through a system level interface. Each data object has an associated user access list. In addition, each object has at least one key indicating which applications can access that object. The key is preferably maintained in a protected storage area, accessible only by the low level system interface. Both the application identifier key and the user who invoked that application must match the identifier information in the data object for access to be allowed to that object. If an unauthorized user attempts access to the data object through the correct application, or an authorized user attempts access through an incorrect application, access to the data object will be denied by the low level interface.read more
