METHOD AND SYSTEM FOR SUPPORTING RIGHT SHARING

摘要

PROBLEM TO BE SOLVED: To support right sharing allowing a user to share a right according to the necessity of the user himself/herself.

SOLUTION: The right sharing is supported by enabling derivation of a sub-right from a sharable right assigned from an assignor to an assignee to control the use of a resource in a calculation environment. When it is confirmed that a calculation device is capable of deriving at least one component of the sub-right from at least one corresponding component of an assigned right and the calculation device is capable of deriving the component of the sub-right from the corresponding component of the assigned right by the confirmation step, a consumption license constituted of the sub-right is prepared to control the use of the resource in the calculation environment.
