Abstract
A method and apparatus checks a set of files against a manifest to determine whether to accept or reject the files. The manifest contains one or more policy sections that describe whether to accept files that are described in the manifest but not received, or received but not described in the manifest. The method and apparatus determines whether files are listed in the manifest but not received, or received but not listed in the manifest, and can accept the files in these circumstances based on the policy section of the manifest. The manifest may also contain a hash result for each file. The method and apparatus can hash the files received and compare the hash result produced with the hash result specified in the manifest. If the hash results computed for the file are different from the hash result for the file in the manifest, the file or the set of files may be rejected.
