Paul Wouters has entered the following ballot position for draft-ietf-avtext-framemarking-14: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/about/groups/iesg/statements/handling-ballot-positions/ for more information about how to handle DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-avtext-framemarking/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Thanks to Carl Wallace for their secdir review: https://datatracker.ietf.org/doc/review-ietf-avtext-framemarking-13-secdir-lc-wallace-2022-04-11 which raises a good point about referencing RFC 8285 and authenticated headers. Additionally, I wonder why this document has no Privacy Considerations Section. By exposing previously encrypted information on the outer header, some private information is exposed. For example, when watching a TV or live event stream, just by exposing the Independent Frame bit one might be able to deduce the content being watched. And perhaps advise could be added to not send these bits all the time, but only when an RTP Switch requests it specifically (and then deny excessively repeated attempts to foil fingerprinting the stream). Please consider adding a Privacy Considerations section, or let me know why this would not be useful
