>>> Hello Privacy group,
>>> I'm not clear as to the status of the privacy review of the Presentation API specification. I see that there has been an initial review led by Greg [1] which was also used to fine-tune the privacy questionnaire, and then a call for volunteers to finalize the review [2], although I did not find something else in the mailing-list. Could you clarify the current status?
>>> The Second Screen Working Group had its F2F at TPAC and went over the review at [1]. It seems very focused on audio/video, and we wonder whether that is intended. The Presentation API has two modes of operation:
>>> - the 1UA case where a user agent renders the content at the requested URL locally and indeed streams the resulting audio/video to the second screen
>>> - the 2UA case where a user agent connects with another user agents to ask it to render the content at the requested URL. No audio/video streaming occurs in that case, but a communication channel gets established between the two user agents.
>>> I think the group's idea is to see the 1UA case along the lines of: the second screen is part of the "computer" where the user agent runs, which controls the audio/video link in the same vein as it controls the usual "link" with the main display over some internal bus or a VGA/HDMI/Miracast connection. Is the potential privacy concern around the fact that the audio/video stream could be intercepted, or that the second screen could perhaps be considered as a separate computer that could record the streams?
