An apparatus for validating integrity of metadata in a standard file includes: a metadata acquiring unit for acquiring metadata from a protected file; an integrity evidence value acquiring unit for acquiring an integrity evidence value from a file or a database; a secret information extracting unit for extracting secret information of a file data; and a metadata integrity validating unit for checking if the metadata is correct by using the acquired metadata, the acquired integrity evidence value, and the extracted secret information.
