Presto Vivace's Journal: File sharing and privacy

Rapidshare Shares Uploader Info with Rights Holders

Pretty much all torrent sites keep track of the IP-addresses of their (.torrent) uploaders, and if the rights holders can get the IP-address of people who upload to file-hosting services such as Rapidshare, they can easily extend this to BitTorrent sites hosted in Germany. A dream come true for copyright holders, but a nightmare for the privacy of Internet users.

Privacy will be the next killer app on the internet. The company that solves the privacy problem will be sitting on a mountain of money.
