Companies who provide customers with a connection to the internet may soon have to retain subscriber's private web browsing history for law enforcement to examine when requested, a move which has been widely criticised by industry insiders. The Attorney-General's Department yesterday confirmed to ZDNet Australia that it had been in discussions with industry on implementing a data retention regime in Australia. Such a regime would require companies providing internet access to log and retain customer's private web browsing history for a certain period of time for law enforcement to access when needed, according to Australian internet service provider sources. Currently, companies that provide customers with a connection to the internet don't retain or log subscriber's private web browsing history unless they are given an interception warrant by law enforcement, usually approved by a judge. It is only then that companies can legally begin tapping a customer's internet connection.
