Samsung adds Private Sharing mode to Quick Share, E2E encryption for backups, synced data

Samsung’s Knox security suite has gained two new features – Private Sharing and E2E encrypted cloud backups. Here’s how they work.

Private Sharing is a new option in the Quick Share menu. Just tap the “…” button in the top right corner and choose Turn on Private Sharing. This allows you to share up to 20 files at once with a total size of up to 200MB.

You can allow only certain contacts to view the shared files and you will be notified when they do. You can also set a timer for automatic expiration of the shared data. Both settings (who can see the data and when it expires) can be changed at any time.

Your images are protected with a read-only setting (that means they can’t be re-shared), even screenshotting is blocked. The shared data is protected by “blockchain-based encryption technology”.

The new Private Sharing feature of Quick Share

Note: Private Sharing is supported between Galaxy devices running Android 10/One UI 2.1 or later. You can share images (.jpg, .png, .heic, etc.), videos (.mp4, .mkv, etc.), audio (.mp3 and so on) as well as documents (.txt or .pdf).

Starting with the Samsung Galaxy S24 trio, Samsung’s Enhanced Data Protection feature offers end-to-end encryption (E2EE) for your backups and synced data. This means that the data stored on your Samsung Cloud account can only be decrypted by your device – even if the server gets compromised and the data stolen, its contents can’t be accessed.

To activate this feature, head over to Samsung Cloud, tap the “…” button and choose Settings, Enhanced Data Protection. You have individual toggles for encrypting backups and synced data.

When you activate this feature, you will be given a recovery code to write down – this is so that you can regain access to your data in the case that you lose your device.
