Data Deduplication

[neo]

@oxhill

but isn’t the stored chuck encrypted by a client-specific key?

No, the self encryption algo uses the data itself to form the encryption. This allows anyone who has the datamap of the chunks to decode the file. Each chunk on its own is “impossible” to decrypt, but once you have all the chunks in sequence (datamap) then its possible to decrypt the chunks.

Sorry I don’t have the link to the self encryption encryption with me, but I’m sure a search on “self encryption” in the forum will bring a wealth of information.

EDIT: follow this link and the post has a video in it that explains it (hopefully since I didn’t watch the vid to check)

Not user friendly?

In this video, @dirvine already explains how self-encryption works. It also shows that you’re data-atlas and all the other personal data like private keys etc. are self-encrypted as well. So you’re files are encrypted using self-encryption, really not recognizable because the hashes of the chunk A are used to encrypt chunk B etc. Another layer of protection is done by doing a XOR-trick where you really cannot say anything about that data at all. So here you have a data-atlas of all the chunks a…
