Abstract

Computerized systems for authoring, distributing, and using software resources use authorization codes to restrict the use of such resources. For example, the distributed resources might include one or more documents and one or more page imaging resources, where a given document contains references to one or more page imaging resources, such as fonts, which can be used in rendering an image of such a document, and where the authorization code determines if the page imaging resource referenced by a given document is authorized for use with it. In such a scheme, an authoring system allows a user to pick which page imaging resources are authorized to be used with what documents and the system creates authorization codes which reflect the selected authorization. The resources can be distributed in different ways, such as over a computer network or on computer readable media. The authorization code can indicate the address, such as on a network or recording medium, of the documents with which a given page imaging resource is authorized for use, and can be included in its associated page imaging resource's file. The player system used in such a scheme checks if the address from which it obtains a given document matches one of the addresses in a page imaging resource's authorization code before allowing the page imaging resource to be used in rendering the given document.
