Screen Capture Protection for Jami: Prevent the OTHER Peer from taking screenshots and/or Screen recording
all operating systems:
Is it possible to prevent screen recording with another screen recording app (Windows 10, Android etc.) or hdmi capture card? (https://medium.com/pallycon/how-netflix-protects-contents-part-2-33c1b60002a3 )
This feature should allow me to enable an option that prevents OTHER Jami user(s) from taking screenshots and/or recording the screen - and they should not be able to disable that option.
For example like this messenger: https://9to5mac.com/2018/01/10/confide-messenger-screenshield-screenshot-prevention/ So nobody can record a video call (if you (sender/moderator/admin) enable this setting within Jami)?
Similar (this case just your own screen): https://www.opswat.com/products/oesis-framework/anti-screen-capture
Ideally I can also have an audio protection that does not allow OTHER peers to record the audio of a video/ audio-only call.
Activity
The idea is: If you make a video call (moderator) you can select "restricted" so that all participants can see and hear you and themselves on screen but if another person records the video call (using screen recording apps) the video recording only shows a black screen (ideally no sound can be heard too).
Example: https://youtu.be/HH0o-tDExZ4?t=52 or https://www.youtube.com/watch?v=g8C4HdhywvQ

Sorry if this issue already exists. I was not able to find something similar.
May I ask: regarding android:
Can Jami prevent OTHER user(s) from taking screenshots (and recording their screen to videos) ?
I though you can just prevent screenshots (and screen recordings) of Jami on your own Android device?
If someone is able to record in restricted apps (example: https://www.youtube.com/watch?v=T3gZKjV7hwA), does Jami have a second protection so the person CAN record a call but the video only shows a black or white screen? This would be great for all operating systems. Together with the possibility that (just) moderators have the ability to record protected content (audio and video).
Is there a way to prevent OTHER user(s) from recording sound of your audio/video call (so if you use a call recorder or any other sound recording software there is no sound (voice) in your call recordings)?
Can Jami prevent OTHER user(s) from taking screenshots (and recording their screen to videos)?
No, and there is always workaround to take screenshots
Is there a way to prevent OTHER user(s) from recording sound of your audio/video call (so if you use a call recorder or any other sound recording software there is no sound (voice) in your call recordings)?
Same, there will be always workaround to record sound/video. The only thing we can really do is the notification that a peer is recording (but this will only work if they use the recorder in the app) which is already there
So you think that even Confide's screenshot-proof messenger can't effectively prevent OTHER user(s) to record the screen with all the messages or any other content (technology: https://screenshieldkit.com/)? - Except using an external camera.
For example I found out that if you activate incognito mode in Firefox (android, any device (tablet, smartphone)) and you record / share the screen you just see a black window. As soon as you disable private browsing you can see all the content again.
Is there really no way to use such technology for Jami mobile (android) so that OTHER Persons (no moderators) are not easily able to record the video call (just a black screen)?
So regarding (data) privacy: The only way to prevent other people from recording a video / audio call is to make no audio or video call?
The only thing we can really do is the notification that a peer is recording (but this will only work if they use the recorder in the app) which is already there
This would be a feature request (including conferences). So you get a notification like "User123 started a video call recording" OR "User123 and User34 started a video call recording; User56 started an audio-only call recording". AND same if the user(s) stopped a recording.
And it would be great if you were able to select if (for example if you are in a conference) just the moderator(s) get(s) a noticiation or if ALL participants get such a notification.
So once this patch jami-daemon#699 (closed) is merged all peers should now get a notification?
Now even WhatsApp will have a screenshot protection (for the OTHER peer): https://9to5google.com/2022/08/09/whatsapp-screenshot-blocking-privacy-update/
So it should also be possible for Jami to prevent the other user from taking screenshots?
Not just your own screen? At least Jami on Android?
But you can just disable screen capture of your own phone?
I would like to have an option as soon as (ONLY) you enable options like "secret chat" or "secret video call" ALL peers (even if they allowed to capture their own screen before) can't take screenshots anymore. (Ideally all supported OS not just Android)

Since Jami is open-source/Free software, this is not possible.
Changing the Jami source code to disable such a feature will always be possible. Also, people can always capture the screen with an external camera.
Making a promise that the other side would not be able to record would be lying to the user and breaking their trust.
Not sure if Confide is open-source.
But they claim that their messenger is Screenshot-Proof. https://getconfide.com/
(Android only?; the OTHER peer should not be able to take pictures of your conversation)
Of course you can also use a "real" camera to simply record the screen or you can use a capture card.
But of course this takes time and if someone just quickly wants to take a screenshot and it doesn't work this would be enough imho.
Android has an API to prevent recording, but this would only be guaranteed on a non-rooted Android phone.
Still, we might in the future add the "please don't record" feature that would allow to formally inform others that we don't want to be recorded, which would disable the related Jami feature for contacts, without any guarantee.
D'accord avec @aberaud "Faire une promesse que l'autre partie ne serait pas en mesure d'enregistrer reviendrait à mentir à l'utilisateur et à briser sa confiance." Mentir à l'utilisateur est monnaie courante des logiciels privateurs c'est pourquoi nous apprécions l'éthique du logiciel libre en général et de jami en particulier.
