5. Security Considerations
The MIME subtype registration procedure specified in this memo does
not impose any security considerations on its own. This memo also
contains several MIME type registrations. The registrations
themselves do not impose security risks, but some may state security
considerations specific to the particular registration.
Several audio and video encodings are perfect for hiding data using
steganography.
The RTP specification, RFC3550, provides security considerations for
the transport of audio and video data over RTP, including the use of
encryption where confidentiality is required.
