摘要:
The present invention provides a computer implemented method, data processing system, and computer program product to selectively extracts compressed-encrypted files from an archive. The data processing system receives a command to preprocess the archive from an authenticated user, wherein the authenticated user is associated with at least one fingerprint. The data processing system determines that the at least one fingerprint fails to match all fingerprints in metadata of a first compressed-encrypted file in the archive. The data processing system, responsive to a determination that the fingerprint fails to match all fingerprints, deletes the compressed-encrypted file. The data processing system determines that the fingerprint matches a second fingerprint in metadata of a second compressed-encrypted file in the archive. The data processing system, responsive to a determination that the fingerprint matches the second fingerprint, avoids deleting the second compressed-encrypted file.
