The file sharing service Mega, which should replace Megaupload, will be practically invulnerable, promises Kim Dotcom. All files uploaded to Mega servers will be encrypted in the browser. The key will remain with the user who uploaded the file, and neither the hoster, nor the provider, nor Dotcom itself will know what is stored on its servers. In addition, the servers themselves will be located in at least two different countries, so that the confiscation of equipment by the secret services of one country will not lead to data loss.

The user will decide whether to publish the key, or share it with friends, or even hide it away. If the organization of the right holders can find this key and prove that a specific encrypted file contains illegal content, then the Mega administration, so be it, will delete this file. However, due to encryption, deduplication of files on the server is technically impossible, and there will be no way to destroy all instances of the same file at one stroke. If it is downloaded a hundred times, encrypted with hundreds of different keys, the right holders will have to work with each copy separately.
Such a scheme will make it very difficult to block any files, the keys to which are not published in the public domain, but are distributed in a Friend-to-Friend scheme between users trusting each other.

Also, Dotcom promises film studios and record companies the ability to delete files that they do not like by a simplified procedure, if they sign an agreement to ensure that they do not complain about the service itself.
In the future, Kim Dotcom wants to create not just a centralized web service, but a whole network of thousands of independent nodes, each of which will store part of the Mega files, so his site will remain only the facade of this network, which makes its closure even less likely. Dotcom claims that its lawyers have worked well to ensure that the new file sharing service does not repeat the fate of Megaupload.
