How does raw format contribute to data hiding techniques?
Data hiding techniques by providing an unprocessed state that allows for easier manipulation and embedding of hidden information.
Raw format is only used for image files and does not relate to data hiding.
Data hiding techniques require processed formats for effective embedding.
Raw format complicates the manipulation of hidden information.
Explain the role of metadata in file format analysis.
Metadata provides key information that helps identify and interpret the file's structure and content.
Metadata is irrelevant to understanding file content.
Metadata is only used for file storage purposes.
