First challenge: Tracing misuse of personal data in India within vast digital ecosystem presents a dauting task. Second challenge: The techniques used by cyber criminals such as data encryption and anonymisation add layers of complexity to investigation requiring advanced forensic capabilities and specialised expertise.
