This problem is also getting serious in India, which is justified in its criticism of the US for its snooping operations but it should not do similar things domestically, Amnesty International's Secretary General Salil Shetty told PTI here.
Speaking on the sidelines of the WEF Annual Meeting, Shetty said that the 'Big Brother' problem relating to US government has become the defining issue of this time as far as rights of common people are concerned globally, just as the issues like human rights in 60s and 70s, and women rights in 70s and 80s.
"On the one hand, the mobile phones are very empowering in nature, but on the other hand, these mobile phones have also created a situation where government and the companies may be watching you.
"If some one wants to track you down, it becomes very easy today through mobile phones. For repressive governments, it has actually become a new tool for repression," he said.
Shetty said that most of the constitutions enshrine the right to privacy as a fundamental right of a citizen and there is a good reason why this provision has been made.
"Governments have a responsibility to protect the citizens and they have got this very legitimate right to provide security. But this right comes with a lot of responsibility. So if you want to collect data and to snoop on people, you have to have a legal basis for doing so. You cannot just do the mass surveillance.
"You just cannot go on a fishing expedition and you must have sufficient reasons if you want to tap a phone. There must be a judiciary order to tap phones and the governments cannot do such things on their own. One have to be very careful about these things," he said.
