摘要：
There are disclosed methods and systems (and related data structures) for processing metadata in files, including media files, so that an alteration or falsification of the metadata can be detected. According to certain embodiments, the metadata includes hash values and digital signatures that were generated by a content server. These hash values and digital signatures can be used by a client device to authenticate the metadata.
