In a query-response model system of network communication, to protect user data privacy, a plurality of Camouflage Queries are automatically generated to be sent along with Intended Queries. The mix of intended queries and the Camouflage Queries masks and obscures the intended queries. Camouflage Messages or queries create a noisy background and thus lower the signal to noise ratio (SNR) for a server or interceptor to detect the intended queries.
