ABSTRACT:
A method and computer-readable medium are provided for generating usage rights for an item based upon rights to access the item. According to the method, a request is received at a document management system for an item stored in a library. In response to the request, access rights to the item for the requester are determined and usage rights are generated based upon the access rights. An encrypted file is then created that contains the item and the usage rights for the item. The location of the item in the library may also be included in the protected file. When an attempt is made to store the item back in the library, a comparison is made between the location where the item was previously retrieved from (as specified within the item) and the requested location in the library for saving the item. The item is only saved in the library if the two locations match.
