"Implicit consent" has specific meaning in privacy community work, meaning that consent is given through action with an understanding of the import, as opposed to "express consent" (or explicit consent) granted by signing a form for example.

Thus this is not colloquial usage and for that reason  I would suggest to keep the existing language. We might consider adding a reference to the Web Application Privacy Best Practices Note[1]; or reference   Opinion 15/2011 on the definition of consent<http://ec.europa.eu/justice/policies/privacy/docs/wpdocs/2011/wp187_en.pdf> which goes into more detail directly (it is referenced from the Note)

Thank you for your comment. The proposed addition addresses the concern we raised, but we have an editorial "friendly amendment". Where the addition says "... giving implicit consent ..." we suggest to replace "implicit" with "explicit", or to drop that qualifier. While "implicit" can mean "unreserved" it also can mean "implied, rather than expressly stated", which conveys a different meaning than is probably intended. The word "explicit" means "fully and clearly expressed or demonstrated" and is probably the intent. If that is not, or if it still seems confusing, it might be better just to drop the qualifier, which could raise more questions than add clarity. Just saying "... giving consent ..." may be sufficient.

We hope you will take this edit to minimize ambiguity, but in any event the PFWG formally accepts your disposition of comment LC-2636.

Your comment on 4. Security and privacy considerations This specification

The Protocols and Formats Working Group took a quick look at the HTML
Media Capture specification
http://www.w3.org/TR/2012/WD-html-media-capture-20120712/. In a
teleconference discussion, minuted at
https://www.w3.org/2012/07/18-pf-minutes.html, we had the following

    * The specification should make explicit statements about security
      expectations, e.g., requesting permission before turning the
      microphone on in order to capture from it.

Working Group Resolution (LC-2636):
Text added to to the Security and Privacy Considerations section

"The user agent should not enable any device for media capture, such as a
microphone or camera, until a user interaction giving implicit consent is
completed. A user agent should also provide an indication when such an
input device is enabled and make it possible to terminate such capture.
Similarly, the user agent should allow the user:

* to select the exact media capture device to be used if there exists
multiple devices of the same type (e.g. a front-facing camera in addition
to a primary camera).
* to disable sound capture when in the video capture mode."
