<p>A system and method for verifying the integrity of digital content in a server environment is described. Content from the server environment, as from a publishing server, is transferred to a content distribution server via a content integrity device. The content integrity device performs cryptographic operations on the content prior to its arrival at the content distribution server. The results of the cryptographic operation are associated and stored with the digital content. Upon receiving a request for the digital content from a source outside of the server environment, the content distribution server identifies and forwards the digital content and results of the associated cryptographic operation to a second integrity device. This device verifies the integrity of the content by comparing the results of similar cryptographic operations performed by the second integrity device with those performed by the first content integrity device.</p> |
