There are a number of ways through which you can transfer files between mobile devices. You can use Bluetooth, NFC, Nearby Share, Samsung’s Quick Share or just shoot your recipient an email if it’s not a big file. The question remains, how do you go about ensuring the security of what you’ve just shared?

Samsung seems to have been thinking along the same lines. We hear that the company has been developing a new app called Private Share. This app is going to leverage the power of the blockchain to enable secure file transfer.

Private Share is going to allow users to share their files privately. It’s the same concept as ephemeral messaging. The sender will be able to set an expiration date for the files. The shared files would automatically be deleted from the recipient’s device after expiry.

Recipients will also be prevented from resharing the files. The app will not provide them with an option to reshare the file. Screenshots would ostensibly be disabled as well, but there’s nothing stopping anybody from taking a picture of that device’s screen with another device.

The app will work much in the same way as Quick Share, in that both the sender and the recipient will need to have the Private Share app. The sender will send a transfer request which when accepted by the recipient will create a channel and start the transfer.

It’s quite likely that we’ll see Private Share being introduced as one of the new features that Samsung introduces with the Galaxy S21. Like it did with Quick Share and Music Share, the app will then quickly be rolled out to previous flagships and even mid-range devices. It will really only be useful for Samsung users when the app is available on a wide variety of Galaxy devices.

Fortunately, we won’t have to wait long for the Galaxy S21 lineup. SamMobile has already exclusively confirmed the Galaxy S21 announcement for early January 2021. The handset is expected to hit shelves towards the end of the month.
