Abstract
A method of providing automatically verifiable trust in a content resolution process in which a PDR resolves a content reference identifier (CRID) identifying a content item using a resolution authority record (RAR) to obtain a locator identifying a location where the PDR can obtain the content item. Preferably, the measure comprises computing a digital signature over at least part of the contents of the CRID, the locator and/or the RAR. The method may also comprise encrypting at least a data portion of the CRID, RAR or locator. Digital rights needed to access the content item can be provided with the CRID, RAR or locator.
