MUMBAI: The controversy over Aadhaar on Friday triggered a heated spat between P Chidambaram and NR Narayana Murthy , with the lawyer-politician flagging concerns from a libertarian perspective and the Infosys co-founder stressing on the need for Parliament to enact laws to protect privacy.Flaying the Modi government's strident move to get everything linked to this national identification number, Chidamabaram said the "government is completely deaf" to any reasoning against linking Aadhaar to everything under the sun.Like any other modern country, there is a need to establish individual identities in the form of a driving licence, at the same time ensuring that there is no violation of privacy with such an identification, Murthy said, speaking at IIT-Bombay's annual Mood Indigo festival here this evening.Chidambaram on the other hand argued that using Aadhaar for every transaction has "serious consequences" that will turn the country into an "Orwellian state", compromising the ideals of a liberal democracy and an open society."If a young man and a young woman want to have a private holiday, they may not be married, what's wrong with that? If a young man wants to buy condoms, why should he disclose his Aadhaar or identity?" the former finance minister quipped."Why should the state, that is the government, know what medicines I buy, what cinemas I visit, what hotels I stay in, who are my friends?" he asked further."If I am in the government, I should resist the temptation to know about all these activities which individual citizens do," he said.Retorting back, Murthy said, "I disagree with you ... all of the things you talked about are available through Google today."Chidambaram said he has not linked his bank account with the Aadhaar number and appealed for a pause on linking activities till January 17, when the a five-judge Constitution bench is slated to resume hearing the bunch of petitions on the matter.He further said right now, all the Aadhaar linking is being done not voluntarily by the people but as a tool to "conform" because of the barrage of SMSs and mails."The question is: there are many agencies which say, 'give me your Aadhaar. And even crematorium is asking for Aadhaar today!," Chidambaram said, clarifying that he doesn't oppose Aadhaar as a means to establish identities and help extend government subsidies.When pointed out about the potential misuse of the individual data while availing of services by the chair of the panel, Murthy said we should not "trash" Aadhaar and took jibes at Parliamentarians for not coming out with a privacy law that can help protect an individual's data.In the wake of criticism of hiding wrongful transactions against those opposing Aadhaar, Chidambaram made it clear that there is nothing to hide and any investigative agencies can access details if needed."... that record should not be accessed by a hacker or a big brother in the government using my Aadhaar. That's my objection," he said.The former two-time finance minister in the Manmohan Singh government, that brought in the Aadhaar, pointed out that the original idea of Aadhaar was to help transfer government benefits and subsidies and plug the leaks."Where there are no government subsidies or benefit being transferred, there is absolutely no reason to link to Aadhaar. There are serious consequences of doing that. But this government seems to be completely deaf to any reasoning against linking Aadhaar to everything under the sun."Picking up quickly on it, Murthy shot back saying "that responsibility is of Parliament ... to ensure that the executive does not do it. You have all the powers."Murthy further said, "Aadhaar is nothing but a simple verification of the identity of an individual. There is no privacy issue here. We've a certain way of identifying individuals and it's like a driver's licence in which there is no privacy violated by that."To this, the former home minister retorted saying Murthy is "disarmingly innocent", and private people do listen-in to calls.The two finally did agree, with Murthy saying, "as long as there are laws that protect privacy, there is no issue. I'm not saying you need an Aadhaar to book a film ticket, or some other trivia."This led Chidambaram to say "in the revised formulation, I entirely agree with Mr Murthy"."The beauty of disagreeing with Mr Chidambaram is that you can disagree with him as long as you are not disagreeable," Murthy concluded.
