The former Chief Information Security Officer at the Prime Minister's Office, Dr Gulshan Rai has warned that one-sided, simplistic solutions like attaching a unique ‘hash’ proposed by third party experts may not be a permanent solution to the message traceability issue with encrypted messaging platforms like WhatsApp. <br /> <br />Speaking exclusively to India Today TV, Dr Rai said that both the government and the technology platforms needed to sit together in order to come up with a balanced solution.
