Abstract

Information rights management (IRM) systems are used to protect the use of information within a data item. An IRM system is provided which will allow access to a data item following at least two interactions with one or more licensing entities. In some examples, the license entities may each issue a license containing part of the information required to access the data item. Each license part may correspond to part of a use policy. For example, a first licensing entity may issue a license to access a document based on one requirement and a second licensing entity may issue a license based on a different requirement. In other examples, a licensing entity may require a second licensing entity to perform a validation before it issues a use license.
