You might have read about data security (or the lack of) because of snooping by the NSA and GCHQ; multi-nationals being hacked and embarrassed on a global scale; or whistleblowing by the likes of Edward Snowden. Data security is an understandable concern for individuals, businesses and charities.
Following the iCloud hack in 2014, a positive outcome was to focus the mainstream media’s attention on data security and who is responsible for protecting the data. Ultimately, the owner of the data (not the cloud storage provider) is responsible. Our advice is:
Encryption is the most secure technique to protect data saved to cloud-storage that doesn’t automatically encrypt data. Encrypted data remains safe from hackers and unethical employees. However, if you forget the encryption password, you’ll be unable to decrypt your data, so be careful. After Boxcryptor sold out to Dropbox, we used Cryptomator.
Instead of using cloud storage plus an encryption solution, an alternative is to use encrypted cloud storage. Sync (5GB for free) protects privacy with end-to-end encryption; ensuring your data in the cloud is secure and 100% private. If you lose your password, there will be no way to recover it because Sync keeps no record (known as zero-knowledge). We also use Filen (10GB for free).
End-to-end encryption is a data security measure that scrambles information at its origin and only decrypts it at its destination, making it unreadable to anyone in between. This is important because:
In summary, end-to-end encryption is a cornerstone of modern digital security. It enables individuals and businesses to communicate and share data securely, fostering a safer and more trustworthy digital environment.
