Is there a secure cloud?

Question

Information Security

Good afternoon!
I am paranoid. I have nothing to hide, however, I would really hate for someone to have access to my data, at least to media files.
Is there such a decentralized storage (cloud)? Icloud is being checked. Google drive - checked. They themselves write about this in their terms of use, although they say that the data in their repositories is filtered to search for childporn. But what if tomorrow they change the filters and will already be looking for faces? They will search through their vaults for my photo and find my whole life.

I need just such a cloud, where there is synchronization of a mobile phone-computer-tablet. So that you can log into one account from any device and use your data.
I'm also considering options with physical hardware, which means I can buy and install a mini-cloud in my home, where I will upload information. When I personally have a cloud, there is at least hope that the data is encrypted and no one can decrypt it without physical access.
I heard about many options, for example: NextCloud, ownCloud, open source.

Can you give literature or your personal advice?

Answer 1

No
, and it can't be. "Secure cloud" is an oxymoron. By definition, you trust the admins of the storage where your data will be stored. Just a word, without any possibility of verification. The only way to use it is to store encrypted files - archives with a password or encrypted with a certificate when encryption was done by you . Indeed, it is terribly inconvenient.
The option of setting up a server at home is noticeably better - of course there will be admin-type problems - installation location, lighting, backups, spare parts, etc. - but this option removes the issue of access "on the sly". Synology has DSCloud with clients for Windows and Android (or maybe for everything else, I don't know) - if you trust synology, you can install it.

Answer 2

I use the file-crypt-container.
The easiest and most reliable way to prevent file parsing by the other side.

Answer 3

You can make a distributed cluster of VDSok or home servers. But the easiest way, as mentioned above, is to store cryptocontainers.

Answer 4

There is a TresorIt cloud, but (a) it's paid, and (b) you have to trust them.
The cipher container is not the best option for the cloud, there will be a lot of traffic, glitches are possible.
It is better to use file encryption. It's so convenient here. When I was not too lazy, I used BoxCryptor (essentially EncFS under Win). I set him on a folder, he transparently encrypted everything in it. This folder was in my dropbox. The utility itself mounted it as a virtual disk, with which it was possible to work transparently on the fly. Those. already encrypted files are synchronized to the cloud, while I locally work with decrypted files transparently and without any effort.
But here you have to trust the encryption utility :)
The free functionality is limited.

They will search through their vaults for my photo and find my whole life.

They can do it without pictures.

I am considering options with physical equipment, that is, I can buy and install a mini-cloud at home, where I will upload information. When I personally have a cloud, there is at least hope that the data is encrypted and no one can decrypt it without physical access.

Do you trust the provider, the OS manufacturer, the NAS manufacturer, the router manufacturer, the application software manufacturer? All these points are potential places for data leakage, if you are completely paranoid.

Answer 5

I agree with John, I use Rohos Disk instead of BoxCrypt. (Win/Android) for 4GB free. works with any cloud.
If you have "hands" + time + where to put the Server, then use NextCloud as your Cloud. full analogue of gmail + drive + photos. There are win / mac / ios / android app synchronizers. and an online document editor I think will be there soon. A friend showed me how he unrolled for the whole family. and kept all the photos there. Super!
