MEGA is designed both to compete with cloud storage giants like Dropbox, Google Drive, CX , Evernote and RapidShare—and also to insulate itself from future charges. The difference that makes a difference is that all files are encrypted using a 2048-bit RSA key. (See a detailed writeup on Ars Technica for more details.) What this means effectively is that Dotcom cannot be accused of knowingly storing copyrighted materials because he cannot technically know the content of the filesstored on MEGA—only the user who uploaded the files and/or possesses the key can.
