Confidential Web Hosting - Any Recommendations?

[Contrarian]

Dear bros and sisters:

My friend need to publish a file on a SECURE website that is anoynmous and generate a URL link so that viewers can play the file uploaded. Something like the dropbox URL.

The author's identity cannot be disclosed or probed.

Any safe confidential hosting sites? Must it be from US only?

No need. Just use BitTorrent Sync. No external hosting. Direct P2P.
