Mega is expected to use encryption methods which will mean only users will know what they are uploading.
Dotcom is awaiting a decision in March whether Dotcom should be extradited from New Zealand to the US to face charges relating to copyright theft.
The 38-year-old said he would launch Mega on 20 January 2013 – a year to the day since his arrest. By keeping details of files uploaded on Mega secret from the site’s administrators, Dotcom said he believed this would mean the site was not in violation of US laws.
Announcing the new site on Twitter, Dotcom said the holding page was already getting “millions” of hits. The site’s servers will not be hosted in the US, Dotcom added. A page on the Mega site makes a plea to encourage more investors for the service.
Dotcom currently resides in a New Zealand mansion which was raided by local authorities at the start of this year. The raid and seizure of assets was later deemed illegal by a New Zealand court. It was also ruled that intelligence agencies had illegally spied on Dotcom – an incident which drew an apology from New Zealand Prime Minister.
