Iran is developing a system wherein Internet users in the country would be identified at the moment of log-on, said the nation's telecommunications minister.
Mahmoud Vaezi said that when people want to use internet they would be identified and that there would not be any web surfer whose identity would remain unknown, reported News24.
He said earlier that the country would have "smart filtering" within six months to weed out internet content the authorities deem offensive or criminal.
Official figures say that more than 30 million people in Iran use the internet.
Censorship of internet remains a bone of contention between conservative hardliners and government members including President Hassan Rouhani who use social networks.
