Request: Message Replikation Over Youre Own Devices

[Mikki-10]

Sry for this bad google transalte.

Possibility that message is sent to more of your own computers, for example if you have 3 computers and to use the same email to all 3 then find the only one out of the 3 and the 2 computers can you not write unless using the public key as an opportunity to write a message and then it comes to all recipients computers .. 
In the style of that if I sit on facebook and receive a message that will display the message on all the computers that are on facebook, so that the program understands that it must send the same message to all the computers .. 

example 

Friend 1 writing from PC1: 
Hey what are you doing? 

Friend 2 receives the message on PC2, PC3 and pc4 (if online) 
"Hey what are you doing?" 

Friend 2 writing from PC2 to Friend 1 
Reviews Bleep, you? 

The message is then received on PC1, PC3, and pc4 (if online)

Being able to have the same account on multiple devices is definitely on the roadmap. The interesting aspect of this is that the account exists on your computer (in the form of a private key). The only way to clone this account and have multiple devices logged in at the same time, to the same account, is to duplicate the private key. ideally the private key is not sent via any server, but directly between your devices.

 

Our first way of supporting this is by transferring the private key via a QR code. We still need to come up with a reasonable way of transferring it to a device that doesn't have a camera (like a desktop).

I found a fairly simple method of transferring data to a desktop; use the optical mouse.

 

How you ask? Well, I tried displaying a Hermann grid on the phone and slowly panning the image on the phone (since you can't move the mouse you'll have to move the surface). The results seemed fairly random at first, but slowly a pattern started to emerge. While you can't control the direction (since the optical sensor gets confused by the pixels and the cursor starts to shake), you can control when it moves movement. It seems if the sensor encounters a black image it doesn't move at all. If it encounters a white image, it starts jumping around.

 

The general idea is to have movement present a "1" bit and lack of movement represent a "0" bit, since the interval between the random jumps cannot be easily predicted (perhaps with a bit more research this could be possible too). It works best with AMOLED based screens since they have a true off state, however it seems to work with at least some TFT based phones as well.

 

In short, the user would place his mouse on the phone and after tapping the screen, the phone starts to transmit a test message. After the first try the user is asked to input some tweaking parameters like delays in the display pattern. The process is then repeated until the message is successfully transferred.

 

Yes, it would be terribly slow, but it would hopefully work and perhaps even be good enough for sending relatively short messages like a key. Laptops usually come equipped with webcams nowadays, so they're not really an issue.

Is it in any way possible to have one private key per device (so if it gets lost or stolen it won't leak) and shared 'account' e.g. mymail@domain.com that multiple private keys can access?

 

Of course the private keys should be able to be revoked in case of losing/stealing of a device+/privkey. I'm not an encryption expert but something like key escrow?

 

In addition, for enterprise environments this would be interesting as we can have messages decrypted with user private key and/or admin private key (regulations are a bitch...).

why not cut and paste like btsync. how large is a key?
