[@4amalreadyy]

Finally a video that made me understand Yao's Millionaires Problem , Thank you. The pratical example really helped!

You are a legend!

is Db que thing that will desencripte the function EB(x)?

[@SecPrivAca]

Exactly, Db is the decryption function using Bob's private key.

Why there is an inconsistancy in this video, you said if f(x) in Zi, alice earns more in the beginning, but the result shows f(x) + 1 in Zi, shouldn't it be Bob earns more, but you said Alice earns more?

[@SecPrivAca]

Yes, there is a mistake during the theory part of the video. The example is however correct. If f(x)+1 is in Z_i then Alice earns more (as we see in the example).

Dislike music in the background.

I have removed it in my later videos.

What happens when there's equality?

[@SecPrivAca]

If Bob also earns 8, he would increase all numbers following the 9th number, i.e. 9.67 becomes 10.67 So, 8.33 would be unchanged and f(x) would be in the series. That means that Alice knows that she does NOT earn more than Bob. She does not know that he earns as much.
