Thanks Eric ..
for the quick reply.
Yes I accept your point ..actually we are using the .Net webservice and client is Kony mobile framework which one of the cross platform to develope the ios,andriod,windows and desktop. so webservice provide the services for the all apps which developed by the kony.
We are already security followed in server side like implement the https and encrypt and decrypt the response using AES algorthim.but the they are tracking the response and inputs calls from the service using fiddler.
client also same encrypt and decrypt there.but fiddler can able to break the HTTPS and even they are breaking the response .
If any other way to hide the response never shown in fiddler..kindly reply..
