Is it possible for foreign women to travel in India without getting sexually assaulted or harassed for pictures?

All racism and hate aside. I am Indian myself. I'm asking for real. I want to bring my American girl friends to visit Kerala. How can I go about doing this without any incident or embarrassment? I'm thinking of booking a driver and a car so they can be escorted at all times, but it's still impossible to avoid contact with local people, and majority of Indians will undoubtedly act creepy or weird around them.
