What is atCipher Drive?

atCipher Drive is a multi-cloud storage power tool that is designed to keep your files safe in the cloud.
With the convenience of modern day cloud technology, people can access and share their files on the go; however, with convenience comes risk. atCipher Drive protects your data before you upload it to your cloud storage service. Data at rest in the cloud is protected at all times. This way, no unauthorized third parties, such as your cloud storage service, any ill-intentioned cyber-attackers, or even atCipher, can ever gain access to your files. atCipher Drive then allows its users to share these encrypted files with other atCipher users easily and securely.

atCipher Drive is an easy to use, effective security measure that cloud storage users should consider when uploading sensitive or private information to the cloud.

Why should I be concerned with the security of my files?

When you upload a file to the cloud, you're uploading it to the internet, and no cloud storage provider can guarantee your information's safety from malicious cyber attacks. Whether you're an individual storing your tax return or your bank account information, or a graphic designer working with a team and sharing a client's sensitive information, your data could be at risk. atCipher Drive helps you to safeguard your data when using cloud storage.

Why is atCipher Drive more secure than uploading directly to cloud storage or using other similar services?

Most cloud storage providers use server-side protection, meaning that all of the information you need to access your files is stored in the public domain protected by username and password access. Modern encryption techniques have made it impossibly difficult to brute force decrypt an encrypted file without a key, and as a result most security breaches occur during the sharing or accessing of these keys. Fun fact: an attacker using brute force method to crack AES 128-bit encryption would take 318 billions of billions of years on the fastest supercomputer in the world.

Every time you upload, access, or share a file using atCipher Drive, your key is recreated, meaning that at no point is it ever stored anywhere. This eliminates the possibility of anyone ever having access to your key and therefore your data, other than yourself and the people you have authorized.

Furthermore, this also means that atCipher Drive will have true zero knowledge of your data, keys, and password at all times. We cannot decrypt your information even if we were asked. atCipher Drive has excellent security standards; we regularly monitor our networks, and pass self-imposed penetration tests to make sure that we are providing quality security. However, even if someone did manage to breach our security, they would still not have access to any of your information because there is simply nothing to steal. Our method of regenerating your keys upon request ensures your privacy at all times in all circumstances.

atCipher does accomplishes this using a cryptographic algorithm known as Identity-Based Conditional Proxy Re-Encryption in combination with a highly scalable cloud-based secure key management system.

How do I use atCipher Drive?

Our goal at atCipher Drive is that anybody, regardless of technical expertise, should be able to protect and to securely share file. Therefore, we decided to make atCipher Drive's functions as easy to use as possible.

To protect your files inside a folder, all you have to do is to select the folder, then, right click and select "Protect Folder."
Once you have done this, the icon beside your folder should change. This is so that it is easy to distinguish between protected folders and unprotected ones. You can see for yourself that your data is encrypted on the cloud by viewing your files on your cloud storage provider.

To reverse folder protection (to unprotect a protected folder), right-click a protected folder, and select "Unprotect Folder."
The icon beside the folder should revert back to normal icon.

To share a folder, right-click the folder you would like to share, click "Share Folder." After a sharing window has poped up, type in the e-mail address of the person with whom you'd like to share it. Keep in mind, that in order to maintain the integrity of our security system, sharing encrypted folder can only be done between atCipher Drive users.

atCipher Drive will allow users to choose their own cloud storage, and is currently only compatible with Dropbox™. As a security company, we like to maintain total transparency such that our users can see that their information is safe with us. By using cloud storage services that are not our own, we can show our users that we have nothing to hide.
