INTERNET speeds could slow by 30 per cent under the Government's proposed web filtering scheme, even though it will do little to block illegal content.
That's the warning from technical experts, who also say the plan could expose users' financial details during online banking sessions and see popular websites including Facebook and YouTube banned.
The warnings came after Broadband, Communications and Digital Economy Minister Stephen Conroy confirmed the Federal Government planned to introduce a mandatory internet filter, shelving plans to allow Australians to opt out of the scheme.
Internet service providers, who would administer the filter, have been asked to conduct live trials of the filter before the end of the year.
But System Administrators Guild of Australia president Donna Ashelford said the plan was deeply flawed and would slow internet access down by about 30 per cent according to the Government's own laboratory trials.
Despite this, the national web filter would only censor web content, Ms Ashelford said, and could not deal with the remaining 60 per cent of internet traffic, much of which occurred over peer-to-peer networks such as BitTorrent and LimeWire.
"The bulk of internet traffic is over peer-to-peer networks and the bulk of illegal content is trafficked is over peer-to-peer networks," she said. "There is no choke point at which they can block that material. I do not believe this is an issue that has a technical solution."
Electronic Frontiers Australia board member Colin Jacobs warned the web filter could also unwittingly make the internet unsafe for financial transactions by breaking the secure encryption used by banks online.
Five of the six web filters tested by the Australian Media and Communications Authority this year were able to filter websites using the secure protocol HTTPS, which would leave financial details exposed to the internet service provider in charge of operating the filter.
"If they sit in the middle and get between your web browser and the bank's server it really breaks open the security and leaves the details open to attack," he said.
The Minister for Broadband, Communications and the Digital Economy is reported:
"I will accept some debate around what should and should not be on the internet — I am not a wowser," Senator Conroy told The Age. "I am not looking to blanket-ban some of the material that it is being claimed I want to blanket-ban, but some material online, such as child pornography, is illegal."
In response to arguments that the proposal would affect basic civil liberties and the principle that households should be able to be their own internet policeman, he said: "We are not trying to build the Great Wall of China.
"We are not trying to be Saudi Arabia, and to say that is to simply misrepresent the Government's position." [my emphasis]
What a pity that Senator Conroy has already been exposed for lying to the Australian people on the matter of his national ISP-level filtering plans.
