claim 13, reproduced as follows:
13. For a distributed data storage system having plural
data storage devices and plural principals accessing the devices,
a computer-implemented method for managing data access in the
data storage system, the method comprising the acts of:
notionally associating data elements in the data
storage system with colors;
receiving requests for data access from the principals;
and
selectively issuing tickets in response to the
requests, each ticket authorizing at least one type of data
access with respect to at least one color, the tickets being
generated or not in response to requests to manage data access
among the storage devices on the basis of the colors.
The examiner relies on the following references:
