In response to WhatsApp's legal challenge to new digital rules on grounds of violation of user privacy, the government today said it is committed to right to privacy of citizens but it is subject to "reasonable restrictions" and "no fundamental right is absolute". "The government of India is committed to ensure the right of privacy to all its citizens but at the same time it is also the responsibility of the government to maintain law and order and ensure national security," Union IT Minister Ravi Shankar Prasad said.
