Count Mean Sketch

In our use of the Count Mean Sketch technique for differential privacy, the original information being processed for sharing with Apple is encoded using a series of mathematical functions known as hash functions, making it easy to represent data of varying sizes in a matrix of fixed size.

The data is encoded using variations of a SHA-256 hash followed by a privatization step and then written into the sketch matrix with its values initialized to zero.

The noise injection step works as follows: After encoding the input as a vector using a hash function, each coordinate of the vector is then flipped (written as an incorrect value) with a probability of 1/(1 + /2), where is the privacy parameter. This assures that analysis of the collected data cannot distinguish actual values from flipped values, helping to assure the privacy of the shared information.

In order to stay within the privacy budget we do not send the entire sketch matrix to the server but only a random row of the matrix. When the information encoded in the sketch matrix is sent to Apple, the Apple server tallies the responses from all devices sharing information and outputs the mean value for each element of the array. Although each submission contains many randomized elements, the average value across large numbers of submissions gives Apple meaningful aggregate data.
The end-to-end effect of this magic is that Apple can read your characters...so how about privacy ?
 
I think they capture it at the keyboard level, when you type it. Not after it's passed through their servers.

That keyboards are allowed to record what you are typing is the number one reason I stick with the awful stock/Apple keyboard.
Interesting - they can't see imessages but they can see what you type. I guess i'm going to stick with the stock/apple keyboard as well.

I find it very hard to believe that the skull is there but not the poo.
 
How in the world does Apple know this? My emojis should be encrypted!! Next we are going to get photo stats... "The #1 photo sent through iMessage is the Bathroom selfie."

This makes me seriously question Apple's commitment to privacy.

lol.... Tears of joy... awesome stuff.....

Perhaps just a convince the name perfectly fits the popularity.

You just know this one will go viral in seconds.

Differential privacy. A wonderful Orwellian term.

https://en.wikipedia.org/wiki/Differential_privacy includes an example to illustrate the following "individual information can be compromised even without explicitly querying for the information of a specific individual".

Apple started using it in iOS 10.
 
I really do use the upside down smiley too.

I use it with smiley, upside down smiley, smiley in particular, to mean "oh well."

It's like ¯\_(ツ)_/¯ for me, but in proper emoji.
i use upside down when I'm being goofy, which is most of the time and the inquisitive smiley for sarcasm lol.
 
Well, people are very happy in the United States and it's so good! It's a pity that this smiley (emojis.wiki/smirking-face) did not hit the top. :D
