The former US National Security Agency (NSA) contractor, who leaked confidential documents detailing the extensive surveillance activities of the NSA and the UK's GCHQ, called for support at the Hackers On Planet Earth (HOPE) conference via a video link from Moscow, Russia.
Snowden addressed the conference on Saturday, requesting that the hacking community channel its resources into developing anti-surveillance technologies which will make government spying more difficult - and said that he planned to spend much of his future time doing the same.
The former NSA contractor said:
We the people - you the people, you in this room right now - have both the means and the capability to improve the future by encoding our rights into programs and protocols by which we rely every day. [..] and that's what a lot of my future work is going to be involved in, and I hope you'll join me in making that a reality.
