At a presentation in New York, the company also unveiled a new technology called uProxy that allows citizens under some regimes to bypass government censorship or surveillance software to surf the Web.

Known for its "Don't Be Evil" corporate motto, Google has a well-established reputation for resisting authorities around the world who seek to censor its Web properties, including YouTube and Blogger.

A promotional video made by Google featured an endorsement from Balatarin, a popular Persian-language news website that has already tested the digital shield program. Google has also worked to protect an election monitoring website in Kenya, according to Forbes.
