File Format Extension Through Steganography
MetadataShow full metadata
Several file formats in common use can be significantly compressed or refined without noticeable losses in integrity. While various techniques have successfully been used to reduce the footprint of these formats, uncompressed files continue to be readily available in modern systems. The present study repurposes the extra space provided by an unrefined format to store metadata about the file in question. This process does not negatively impact the original intent of the format and allows for the creation of new derivative file types with both backwards compatibility and new features.
