Quantum File Splitter deals with a rather specific case scenario.
Let's imagine three parties: a Sender and two Recipients ("Recipient A" and "Recipient B").
The Sender needs to send a file to both Recipients, but neither A nor B must be able to access the file's content unless the other Recipient agrees to do so as well by providing a proof of consent.
In this case, the following conditions ARE NOT allowed:

• use of passwords;
• use of cryptography;
• unbalanced data distribution (both Recipients must receive the same amount of potential data value).

If you're wondering how all this can be a game, maximize your controlling perspectives.
