Enhanced content resolution method
View Patent ↗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.
1. A method for resolving a content reference identifier (CRID), comprising:
identifying a content item;
obtaining a locator from the identified content item, the locator identifying a location where a specimen of the content item can be obtained;
obtaining, using a content retriever module, the specimen of the content item using the identified location;
providing, using a rights extractor, an access key and a digital right for access to the content to an end user dependent on information provided with the CRID or the locator for obtaining access to the content; and
managing in hardware, using a digital rights management module, access to the content item using the access key and the digital right.
2. A device arranged for resolving a content reference identifier (CRID), comprising:
a locator module configured to provide a locator identifying a location where a specimen of a content item can be obtained;
a retriever module configured to obtain the specimen of the content item using the identified location;
a digital rights extractor module configured to provide an access key and a digital right for access to the content to an end user dependent on information provided with the CRID or the locator for obtaining access to the content; and
a digital rights management module configured to manage access to the content item using the access key and the digital right.
3. The device as claimed in claim 2 , comprising means to verify a digital signature provided for at least a portion of at least one of the CRID and the locator.
4. The device as claimed in claim 2 , comprising means for decrypting at least one of the CRID and the locator provided at least partially in encrypted form.
5. The device as claimed in claim 2 , wherein the specimen of the content item can be obtained conditionally upon verifying a measure applied to at least one of the CRID and the locator to verify integrity.
6. The device as claimed in claim 5 , wherein verifying a measure to verify integrity includes verifying a measure to verify origin authentication.
7. The device as claimed in claim 3 , wherein the digital signature is provided for at least a portion of the locator and can be verified using a public key provided by a CRID provider.
8. The device as claimed in claim 7 , wherein the public key is provided with the CRID.
