How to securely use public cloud storage without losing privacy?

Popular cloud storage providers offer convenient access to files from any device, but the data stored on their servers is typically unencrypted. This means that cloud provider employees, as well as automated scanning algorithms, have full access to your documents, photos, and personal archives, which contradicts the principles of strict privacy.

The only reliable way to protect data in the cloud is client-side pre-encryption. You encrypt files on your computer or smartphone before sending them to the internet using strong cryptographic algorithms, and only then upload the encrypted archives to the remote disk. In this case, only meaningless sets of characters to outsiders are stored in the cloud.

To implement this method, there are special client applications that integrate with popular cloud services and perform transparent "on-the-fly" file encryption without the need to manually pack each document.

Applying this approach allows you to use the unlimited resources of third-party cloud storage for backups and file sharing while maintaining absolute control over your confidential information.
