Cloak

Cloud is a plug—in transport that extends the capabilities of traditional proxy tools such as Shadowsocks, OpenVPN and Tor to avoid sophisticated censorship and data discrimination.

Cloak is not a separate proxy program. Rather, it works by masking proxy traffic as normal web browsing. 

Unlike traditional tools, which have very noticeable traffic fingerprints and can be blocked by simple filtering rules, it is very difficult to accurately identify a Cloak. This increases the collateral damage from censorship actions, since attempts to block the Cloak can also damage the services that the censorship state relies on.?
