In an archive environment data integrity is a crucial factor. Cube-Tec offers two levels of additional checksum security:

• File Security Code, seals the metadata and audio content separately
• MD5 checksum, secures the complete archive file

Both checksum types are generated to go along with the archive file through the whole preservation chain. Should a checksum comparison fail, the combination of MD5 and File Security Code allows to tell if modification (or a defect respectively) happened to the audio portion, the metadata or the header of the archive file.
