A bench headed by Justice BS Chauhan asked the Union Ministry of Communications and Information Technology, of which DoT is a part, to file its response within three weeks.
The bench passed the order after Additional Solicitor General Indira Jaising submitted that the Ministry of Information and Broadcasting, which was earlier issued a notice in the matter, is concerned with content on radio and television and not with regulating websites.
"No problem, we can increase the department," the bench said while issuing the notice to DoT.
The Centre had earlier told SC that it was difficult to block international porn sites in the country and sought time to consult various ministries in order to find a solution.
The court has also pulled up the Centre for taking such a long time in dealing with a "serious" issue while granting it time to devise a mechanism to block such sites, particularly those containing child pornography.
The court was hearing a petition filed by Indore-based advocate Kamlesh Vaswani who pleaded that although watching obscene videos was not an offence, pornographic sites should be banned as they were one of the major causes behind crimes against women.
The petition filed through advocate Vijay Panjwani says that the absence of Internet laws encourages people to watch porn videos and over 20 crore porn videos or clippings are freely available in the market, which have been directly downloaded from the Internet or copied from video CDs.
The petition states that, "The sexual content that kids are accessing today is far more graphic, violent, brutal, deviant and destructive and has put entire society in danger and also poses threats to public order in India.
"Most offences committed against women/girls/children are fuelled by pornography. The worrying issue is that the severity and gravity of such images is increasing. It is a matter of serious concern that prepubescent children are being raped," the petition added.
The petition also referred to the December 16, 2012, Delhi gang rape case in which a 23-year-old paramedical student was brutally assaulted and gang-raped by six persons, leading to her death.
"Offenders' minds are mostly fuelled by pornography as the sexual offender or rapist achieves gratification not from sexual release alone but also from the thrill of domination, control and power," the petition said.
"At best, IPC only recognises the offences of obscenity, kidnapping, abduction and other related offences which are not sufficient to tackle the issue of pornography and such videos," it said, adding that the watching and sharing of obscene videos should be made non-bailable and cognizable offences.
