[Full & Detailed Info] Zero Knowledge Cloud Storage

Daisy updated on Jun 02, 2023 | Home > Knowledge Center

Most computer users heard of Cloud backup and tried to back up their files to the Cloud for data protection. But have you ever heard about zero-knowledge cloud storage? You are coming to the right page if not. This article offered by EaseUS will walk you through zero-knowledge cloud storage.

What Is Zero-knowledge Cloud Storage

Zero-knowledge cloud storage will encrypt all of your files client-side, preventing even access by employees who work there.

zero knowledge cloud storage

Zero-knowledge or no-knowledge in cloud computing refers to an online service that can store, transfer, or manipulate data to maintain a high level of confidentiality, where the data is only accessible to the data's owner (the client) and not to the service provider.

Additionally, zero-knowledge services frequently aim to store as little metadata as possible, storing only the required information for the service to function.

How Zero-knowledge Cloud Storage Works

Zero-knowledge cloud storage is accomplished by encrypting the raw data at the client's side or end-to-end (if there are several clients) without providing the service provider with the password. This is called zero-knowledge cloud encryption.

how zero knowledge cloud storage works

Zero-knowledge or end-to-end encryption is a type of encryption in which neither the sender nor the recipient of the encrypted material is aware of its contents. Instead, data is encrypted by the transmitter using a key that is only known to them and decrypted by the receiver using the same key. When the transmitter and receiver desire to keep the contents of the data private, this sort of encryption is frequently utilized.

The Advantages of Zero-knowledge Cloud Storage

Below, we list many essential advantages of using zero-knowledge cloud storage for your files.

You can always know who has access to your data.

Using a zero-knowledge cloud storage service allows you always to know who has access to and doesn't have access to your files. As a result, even if a government official arrives with a warrant, they can only access encrypted files. In addition, zero-knowledge services cannot disclose customers' credentials since they have zero knowledge, unlike non-private encryption providers, who must send over files and passwords.

It has high trust and reliability.

When it comes to privacy, everyone values it. The distinction between a traditional cloud storage service and zero-knowledge cloud storage is comparable to locking your door and trusting your mother not to open it. Unfortunately, cloud storage services like Google Drive do not provide zero-cloud encryption.

It can protect your data from ransomware and spyware.

You may view, edit, and share files online using cloud services without downloading them locally. This significantly strengthens protection against potential ransomware, malware, and other assaults during data transfer.

The Disadvantages of Zero-knowledge Cloud Storage

However, there are certain drawbacks to zero-cloud knowledge storage because nothing is perfect.

If you lose your password, your data is gone.

Since the zero-knowledge service you selected only stores the data you own, not the key itself, recovery is impossible. So if you tend to become lost in thought, you should stay away from these services because you'll just come to despise yourself when your data is lost and there is no way to retrieve it.

Your user experience may occasionally suffer.

For similar reasons, the majority of cloud storage providers can grant access requests from law enforcement organizations; zero-knowledge providers, on the other hand, are unable to do so because their systems are built to make client data inaccessible without the client's explicit cooperation.

To Wrap Things Up

We talked about zero-knowledge cloud storage in this post. Unlike cloud backup, zero-knowledge cloud storage is too much different. As you can see, despite the enormous benefits of adopting a zero-knowledge cloud service, there are some drawbacks that some users would find objectionable. Hopefully, this article can help you to understand zero-knowledge cloud storage better.
