Storing data in the cloud are modern, easy and efficient way to access it from anywhere through the internet. Cloud storage stores your data in digital pools on storage servers built on virtualization techniques.
But putting your files on cloud also poses some serious issues of some third party deciphering your data being stored. Some uninvited intruder may get access to them by breaking into cloud provider’s servers. Files involving end to end encryption are safe but are vulnerable when they are sitting on the cloud. They can be a chief target for someone looking into your personal space, especially when you are in possession of some highly regulated service.
The solution for this lies in zero-knowledge encryption which allows only you hold the encryption keys. Anyone trying to access your files by breaking into cloud servers will only be able to see encrypted files with no means to decrypt them. Here we present some of the services you can use to save your data from any third party interaction.
