There are many ways a user can transfer files between mobile devices. Technologies and services such as Bluetooth, NFC, Nearby Share, Samsung's Quick Share or, for smaller files, good old email can be used. The question is whether and how the user cares about the security of what he just shared. Samsung seems to be thinking the same way – it is working on a new app called Private Share that will use blockchain technology for secure file transfer. Cryptocurrencies are most often built on it today.
Private Share, as the name suggests, will allow users to share files privately. It's the same concept as disappearing messages - the sender will be able to set a date for the files, after which they will be automatically deleted from the recipient's device.
Recipients also won't be able to share files again - the app won't allow them to do that. The same will likely apply to images, however there is nothing stopping anyone from taking a screenshot using another device.
The app will work in much the same way as Samsung's Quick Share feature, in that both the sender and receiver will need to have it. The sender sends a data transfer request, which, upon receipt by the recipient, creates a channel and begins the transfer.

It is quite conceivable that Samsung will introduce the new application as one of the new features of the upcoming flagship series Galaxy S21 (S30) as he did with Quick Share and Music Share. The app would then target previous "flagships" as well as mid-range devices. In any case, it is clear that it will only be useful for Samsung users if it is available on the widest possible range of devices Galaxy.
As you already know from our previous news, the series Galaxy The S21 should be presented in January next year and go on sale the same month.
